If you're using GLib or Qt add-on libraries for D-Bus, there are special convenience APIs in those libraries that hide all the details of dispatch and watch/timeout monitoring. For example, dbus_connection_setup_with_g_main(). If you aren't using these add-on libraries, but want to process messages asynchronously, you must manually call . The home() slot sets the text to the very first document displayed. The anchorClicked() signal is emitted when the user clicks an anchor. To override the default navigation behavior of the browser, call the setSource() function to supply new document text in . This function was introduced in Qt See also textMargins(). void QLineEdit:: setTextMargins (const QMargins &margins) Sets the margins around the text inside the frame. See also textMargins(). This function was introduced in Qt void QLineEdit:: setValidator (const QValidator *v) Sets the validator for values of line edit to v.
See also setSelection and selectAll. Popping messages manually is retturn useful in very simple programs that don't share a DBusConnection with any libraries or funcion modules. Parameters connection the connection Returns TRUE if not authenticated or authenticated as anonymous Definition at line funciton file dbus-connection. Both horizontal and vertical alignment is allowed here, Qt::AlignJustify will map to Qt::AlignLeft. You can use this to establish a default message handling policy for a whole "subdirectory. Otherwise, the document is displayed normally in the text browser with the text set to the contents qt slot function return value the named document with QTextDocument::setHtml or QTextDocument::setMarkdowndepending on whether the qt slot function return value ends with any of the known Markdown file extensions.
The only way to be sure the server ID is available is to wait for authentication to complete. If a normal application sets this flag, it can break things badly. The connection provides DBusWatch and DBusTimeout objects to the main loop. The D-Bus specification describes the server ID and other IDs in a bit qt slot qt slot function return value return value detail. A DBusConnection represents a connection to another application. Start the line edit without the best default, and when the default is known, if modified returns false the user hasn't entered any textinsert the default value. Always returns FALSE on non-Windows platforms for qt slot function return value, though in theory someone could hook UNIX to Active Directory or something. Gets whether the connection is qt slot function return value open.
Normally, an empty line edit shows the placeholder text even when it has focus. This signal is emitted when the availability of forward changes. Increments the reference count of a DBusConnection. This means you can end up deadlocked if the application you're talking to needs you continue reading reply source a method.
In general, each mode of connecting to a given server will have its own ID. To override the default navigation behavior of the browser, call the setSource function to supply new document text in a valu connected to this signal. You can track the online casino ohne umsetzen source by connecting to the sourceChanged signal. See also QTextEditQLabelQComboBoxGUI Design Handbook: Field, Entryand Line Edits Example. The semantics are not: if the next message would cause us to exceed the maximum, we don't read it. Do not display anything. This property specifies whether QTextBrowser should automatically open links the user tries to activate by mouse or keyboard.

Qt::CursorMoveStyle cursorMoveStyle const void setCursorMoveStyle Qt::CursorMoveStyle style. Gets the current state of the incoming message queue. See also QTextEdit and QTextDocument. Display platform-dependent password mask characters instead of the characters actually entered.
The home() slot sets the text to the very first document displayed. The anchorClicked() signal is emitted when the user clicks an anchor. To qt slot function return value the default navigation behavior of the browser, call the setSource() function to supply new document text in. This function was introduced in Qt See also textMargins(). void QLineEdit:: setTextMargins (const QMargins &margins) Sets the margins around the text inside the frame. See also textMargins(). This function was introduced in Qt void QLineEdit:: setValidator (const QValidator *v) Sets the validator for values of line edit to v. If the passed-in slot is not -1, it's assumed to be already allocated, and its retrun is incremented. The same behavior regurn to right arrow key. See also text and setMaxLength.
Adds a message to the outgoing message queue. GetId method invoked on qt slot function return value bus. Called when a message needs to be handled. Peer messages with a bus name set. Detailed Description A line edit allows the user to enter and edit a single line of plain text with a useful collection of editing functions, including undo and redo, cut and paste, and drag and drop see setDragEnabled. Moves the vwlue forward steps characters. No one can get at the message while its borrowed, so return it as qt slot function return value as possible and don't keep a reference to it after returning it. Typedef Documentation By default, this property contains a combination of Qt::AlignLeft and Qt::AlignVCenter.
If enabled, the line edit displays a trailing clear button when it contains some text, otherwise the line edit does not show a clear button the default. See also fnuction and removeAction. When this property is set to Qt::VisualMoveStylethe line edit will use visual movement style. Pressing the left arrow key will always cause the cursor to move left, regardless of the text's writing direction. The same behavior applies to right arrow key. When the property is Qt::LogicalMoveStyle the defaultwithin a LTR text block, increase cursor position when pressing left arrow key, decrease cursor position when pressing the right arrow key.
If the text block is right to left, the opposite behavior applies. If echoMode is Normal this returns the same as text ; if EchoMode is Password or PasswordEchoOnEdit it returns a string of platform-dependent password mask characters text.
See also setEchoModejust click for sourceand EchoMode. This property holds whether the lineedit starts a drag if the user presses and moves the mouse on some selected text. The echo mode determines how the text entered in the line edit is displayed or echoed to the user. The most common setting is Normalin which the text entered by the user is displayed verbatim, but QLineEdit also supports modes that allow the entered text to be suppressed or obscured: these include NoEchoPassword and PasswordEchoOnEdit.
See also EchoMode and displayText. If enabled the default the line edit draws itself inside a frame, otherwise the line edit draws itself without any frame.
Sets the QLineEdit 's validation mask. Validators can be used instead of, or in conjunction with masks; see setValidator. Unset the mask and return to normal QLineEdit operation by passing an empty string "". When qt slot function return value or cleared, the line edit will be filled with a copy of the input mask string where the meta characters have been removed, and the mask characters have been replaced with the blank character by default, a space. Http://gyeongjuanma.top/gmx-passwort-vergessen-ohne-anrufen/room-casino.php an retturn mask is set, the text method returns a modified copy of the line edit content where all the blank characters have been removed. The unmodified content can be read using displayText.
The hasAcceptableInput method returns qt slot function return value if qt slot function return value current content of the line edit does not fulfil the requirements of the input mask. To get rehurn control e. See also maxLengthQChar::isLetterQChar::isNumberand QChar::digitValue. If truncation occurs any selected text will be unselected, the cursor position is set to 0 and the first part of the string is shown. The modified flag is never read by QLineEdit ; it has a default value of false and is changed to true whenever the user changes the line edit's contents. This is useful for things that need to provide a default value but do not start out knowing what the default should be perhaps it depends on other fields on the form. Start the line edit without the best default, and when the default is known, if modified returns false the user hasn't entered any textinsert the default value. Setting this property makes the line edit display a grayed-out placeholder text as long as the line edit is empty.
Normally, an empty line edit shows the placeholder text qt slot function return value when it has focus. However, if the content is horizontally centered, the placeholder text is not displayed under the cursor when the line edit has focus. In read-only mode, the user can still copy the text to the clipboard, or drag and drop the text if echoMode is Normalbut cannot edit it. Redo becomes vaue once the user has performed one or more undo operations on text in the line edit. The text is not validated when inserted with setText. See also insert and clear. The cursor position is set to the end of the line rwturn the maximum text length to characters. See also text and setMaxLength. See also setText and setMaxLength. See also setText and insert. Copies the selected text to the clipboard, if there is any, and if echoMode is Normal. See also cut and paste.
This signal is emitted whenever the cursor moves. The previous position is given by oldPosand the new position by newPos. See also setCursorPosition and cursorPosition. Copies the selected text to the clipboard and deletes it, if there is any, and if echoMode is Normal. See also copypasteand setValidator. This signal is emitted when the Return or Enter key is pressed or the line edit loses focus. This signal is emitted when the user presses a key that is not considered to be acceptable input. For example, if a key press results in a validator's validate call to return Invalid. Another case is when trying to enter in more characters beyond the maximum length of the line edit. Note: This signal will still be emitted in a case where part of the text is accepted but not all of it is.
For example, if there is a maximum length set and the clipboard text is longer than the maximum length when it is pasted. Inserts the clipboard's text at the cursor position, deleting any selected text, providing the line edit is not read-only. If the end result would be invalid to the current validatornothing happens. See also copy and cut. This signal is emitted when the Return or Enter key is pressed. Note that if there is a validator or inputMask set on the line edit, the returnPressed signal will only be emitted if the input qt slot function return value the inputMask and the validator returns QValidator::Acceptable. Selects all the text i. This is useful when a default value has been inserted because if the user types before clicking on the widget, the selected text will be deleted. See also setSelection and deselect.
See also hasSelectedText and selectedText. Unlike textEditedthis signal is also emitted when the text is changed programmatically, for example, by calling qt slot function return value. Unlike textChangedgo here signal is not emitted when the text is changed programmatically, for example, by calling setText. Undoes the last operation if undo is available. Deselects any current selection, and updates the selection start to the current cursor position.
If no text is selected, deletes the character to the left of the text cursor and moves the cursor qt slot function return value position to the left. If any text is selected, the cursor is moved to the beginning of the selected text and the selected text is deleted. Shows the standard context menu created with createStandardContextMenu. If you do not want the line edit to have a context menu, you can set its contextMenuPolicy to Qt::NoContextMenu. If you want to customize the context menu, reimplement this function. If you want to extend the standard context menu, reimplement this function, call createStandardContextMenu and extend the menu returned. The event parameter is used to obtain the position where the mouse cursor was when the event bingo holiday bonus codes generated.
This function creates the standard context menu which is shown when the user clicks on the line edit with the right mouse button. It is called from the default contextMenuEvent handler. The popup menu's ownership is transferred to the caller. Moves the cursor back steps characters. If mark is true each character moved over is added to the selection; if mark is false the selection is cleared. Moves the cursor forward steps characters. If no text is selected, deletes the character to the right of the text cursor. See also setSelection and selectAll. Moves qt slot function return value text cursor to the end of the line unless qt slot function return value is already there. If mark is true, text is selected towards the last position; otherwise, any selected text is unselected if the cursor is moved.
Moves the text cursor to the beginning of the line unless it is already there. If mark is true, text is selected towards the first position; otherwise, any selected text is unselected check this out the cursor is moved. Initialize option with the values from this QLineEdit. This method is useful for subclasses when they need a QStyleOptionFramebut don't want to fill in all the information themselves. Reimplements: QWidget::inputMethodQuery Qt::InputMethodQuery query const.
Deletes any selected text, inserts newTextand validates the result. If it is valid, it sets it as the new contents of the line edit. See also setText and clear. If Return or Enter is pressed and the current text is valid or can be made valid by the validatorthe signal returnPressed is emitted. Reimplements an access function for property: QWidget::minimumSizeHint. Returns the index of the character directly after the selection in the line edit or -1 if no text is selected. See also selectedTextselectionStartand selectionLength. See also selectedTextselectionStartand selectionEnd. You may dispatch the unprocessed incoming message queue even if the connection is disconnected. However, "Disconnected" will always be the last message in the queue obviously no messages are received after disconnection.
However, DBusMessage does NOT have thread locks; you must not send the same message to multiple DBusConnection if those connections will be used from different threads, for example. Also, if you dispatch or pop messages from multiple threads, it may work in the sense that it won't crash, but it's tough to imagine sane results; it will be completely unpredictable which messages go to which threads. That is, multiple threads can make method calls at the same time. Returns FALSE if it lacks enough memory to add the watch. Definition at line of file dbus-connection.

Member Function Documentation
Called during authentication to check whether the given Windows user ID is allowed to connect, if the client tried to auth as a Windows user ID. Normally on UNIX this would never happen. The result indicates whether or not more handlers should be run. Called when a DBusObjectPathVTable is unregistered or its connection is freed. Found in DBusObjectPathVTable. Definition at line 98 of file dbus-connection. Indicates the status of incoming data on a DBusConnection. Definition at line 80 of file dbus-connection. Indicates the status of a DBusWatch. Definition at line 59 of file dbus-connection. Filters are run in the order that they were added. The same handler can be added as a filter more than once, in which case it will be run more than once.
Filters added during a filter callback won't be run on the message being processed. Allocates an integer ID to be used for storing application-specific data on any DBusConnection. The passed-in slot must be initialized to -1, and is filled in with the slot ID. If the passed-in slot is not -1, it's assumed to be already allocated, and its refcount is incremented. The allocated slot is global, i. If the queue is empty, returns NULL. No one can get at the message while its borrowed, so return it as quickly as possible and don't keep a reference to it after returning it. Qt slot function return value you need to keep the message, make a copy of it. This function can be used to do runtime checking for types that might be qt slot function return value to the specific D-Bus client implementation version, i. Attempts to qt slot function return value messages after closing a connection are safe, but will result in error replies generated locally in libdbus.
This function does not affect the connection's reference count. It's safe to close a connection more than once; all calls after the first do nothing. It's impossible to "reopen" a connection, a new connection must be created. You must close a connection prior to releasing the last reference to the connection. You may not close a shared connection. These connections are owned by libdbus, and applications should only unref them, never close them. Applications can know it is safe to unref these connections because libdbus will be holding a reference as long as the connection is open. Thus, either the connection is closed and it is OK to drop the last reference, or the connection is open and the app knows it does not have the last reference. If there's incoming raw data that has not yet been parsed, it is parsed, which may or may not result in adding qt slot function return value to the incoming queue.
The incoming data buffer is filled when the connection reads from its underlying transport such as a socket. Processing has three steps. If threads have been initialized with a recursive mutex function, then this will not deadlock; however, it can certainly confuse your application. Existing data stored on existing DBusConnection objects will be freed when the connection is finalized, but may not be retrieved and may only be replaced if someone else reallocates the slot. When the refcount on the passed-in slot reaches 0, it is set to Returns TRUE if the structure pointer is returned. Always returns FALSE prior to authenticating the connection.
When these bytes are parsed, they may not add up to an entire message. In particular this happens on initial connection, because all sorts of authentication protocol stuff has to be parsed before the first message arrives. If the connection is not authenticated, this function returns TRUEand if it is authenticated but as an anonymous user, it returns TRUE. If it is authenticated as a specific user, then this returns FALSE. Note that if the connection was authenticated as anonymous then disconnected, this function still returns TRUE. Note that if qt slot function return value connection was authenticated then disconnected, this function still returns TRUE. There are not separate states for "closed" and "disconnected," the two terms are synonymous.
If nothing was registered at this path, the data is filled in with NULL. The size is approximate in that you shouldn't use it to decide how many bytes to read off the network or anything of that nature, as optimizations may choose to tell small white lies to avoid performance overhead. Gets the ID of the server address we are authenticated to, if this connection is on the client side. If a client-side connection is not authenticated yet, the 21.co.uk casino login may be available if it was included in the server address, but please click for source not be available. The only way to be sure the server ID is available is to wait for authentication to complete. In general, each mode of connecting to a given server will have its own ID.
So for example, if the session bus daemon is listening on UNIX domain sockets and on TCP, then each of those modalities will have its own server ID. GetId method invoked on the bus. There isn't a convenience wrapper, but you can invoke org. GetMachineId on any peer to get the machine ID on the other end. DO NOT read or write to the file descriptor, or try to select on it; use DBusWatch for main loop integration. Not all connections will have a socket. If the connection is not socket-based, this function will return FALSE, even if the connection does have a file descriptor of some kind. This can be used for SELinux access control checks click here getpeercon for example.
Not all connections will have a file descriptor. This function always fails on Windows. Returns TRUE if the pid is filled in. Returns TRUE if the uid is filled in. Always returns Qt slot function return value on non-UNIX platforms for now, though in theory someone could hook Windows to NIS or something. The UID is only read by servers from clients; clients can't usually get the UID of servers, because servers do not authenticate to clients. The returned UID is the UID the connection authenticated qt slot function return value. Returns TRUE if the ID is filled in. Always returns FALSE on non-Windows platforms for now, though in theory someone could hook UNIX to Active Directory or something. The user is only read by servers from clients; clients can't usually get the user of servers, because servers do not authenticate to clients.
The returned user is the user the connection authenticated as. The click at this page value indicates whether the user SID is available; if it's available but we don't have the memory to copy it, then the return value is TRUE and NULL is given as the SID. If a connection to the given address already exists, returns the existing connection with its reference count incremented. If the open fails, the function returns NULLand provides a reason for the failure in the error parameter. Pass NULL for the error parameter if you aren't interested in the reason for failure. References NULL. This connection will not be saved or recycled by libdbus. The caller owns a reference to the returned message. This function bypasses any message handlers that are registered, and so using it is usually wrong. Popping messages manually is only useful in very simple programs that don't share a DBusConnection with any libraries or other modules.
Preallocates resources needed to send a message, allowing the message to be sent without the possibility of memory allocation failure. Allows apps to create a future guarantee that they can send a message regardless of memory shortages. This function is intended for use with applications that don't want to write a main loop and deal with DBusWatch and DBusTimeout. As long as the connection is open, this function will block until it can read or write, then read or write, then return TRUE. If the connection is closed, the function returns FALSE. The return value indicates whether reading or writing is still possible, i. Note that even after disconnection, messages may remain in the incoming queue that need to be processed. References FALSEand NULL. In this usage you would normally have set up a filter function to look at each message as it is dispatched. The loop terminates when the last message from the connection the disconnected signal is processed.
If there are no messages to dispatch, this function will block until it can read or write, then read or write, then return. The way to think of this function is that it either makes some sort of progress, or it blocks. The return value indicates whether the disconnect message has been processed, NOT whether the connection is connected. This is important because even after disconnecting, you want to process any messages you received prior to the disconnect. Increments the reference count of a DBusConnection.
The given vtable handles messages at or below the given path. You can use this to establish a default message handling policy for a whole qt slot function return value. It is a bug to functuon this function for object paths which already have a handler. It is a programming error to call this function for a handler that has not been added as a filter. If the given handler was added more than once, only one instance of it will be removed the most recently-added instance. Does thought 300 casino bonus deutschland not block to write the message to the network; that happens asynchronously.
Because this fuunction queues the message, the only qt slot function return value it can fail is lack of memory. Even if the connection is disconnected, no error will be returned. If the function fails due to lack of memory, it returns FALSE. The function will never fail for other reasons; even if the connection is disconnected, you can queue an outgoing message, though obviously it won't be sent. This function cannot fail. This function "consumes" the preallocated resources, they need not be freed separately.
A DBusPendingCall will see a reply message before any filters or registered object path handlers. If -1 is passed for the timeout, a sane default timeout is used. This function does not reenter the main loop, i. This function is used to invoke method calls on a remote object. If a normal reply is received, it is returned, and removed from the incoming message queue.
Member Type Documentation
If an error reply is received, it is converted to a DBusError and returned as an error, then the reply message is qt slot function return value and NULL is returned. This function must be called go here the server side of a connection when that unique casino app remarkable connection is first seen in the DBusNewConnectionFunction. If set to TRUE the default is FALSEthen the connection can proceed even if the client does not authenticate as some user identity, i. Namely, an auth mechanism such as ANONYMOUS that supports anonymous auth must be included in the list of available mechanisms for anonymous http://gyeongjuanma.top/gmx-passwort-vergessen-ohne-anrufen/knockout-city-spiel.php to work.
This setting also changes the default rule for connections authorized as a user; normally, if a connection authorizes as a user identity, it is permitted if the user identity is root or the fuction identity matches the user identity of the server process. If anonymous connections are allowed, however, then beschreibung ballontanz spiel user identity is allowed. Stores a pointer on a DBusConnectionalong with an optional function to be funtion for freeing the data when the data is set again, or when the connection is finalized. Indeed, almost any reentrancy in this function is a bad idea.
Instead, the DBusDispatchStatusFunction should simply save an indication that messages should be dispatched later, when the main loop is re-entered. Sets the maximum total number of bytes that can be used for all messages received on this connection. Messages count toward the maximum until they are finalized. When the maximum is reached, the connection will not read more data until some messages are finalized. The semantics qt slot function return value the maximum are: if outstanding messages are already above the maximum, additional messages will not be read.
The semantics are not: if the next message would cause us to exceed the maximum, we don't read it. The reason is that retrn don't know the size of a message until http://gyeongjuanma.top/gmx-passwort-vergessen-ohne-anrufen/2-spieler-spiele-kostenlos-online.php we read it. Thus, the max live messages size can actually be exceeded by up to the maximum size of a single message. Also, if we read say lsot off the wire in a single readand that contains a half-dozen small messages, we may exceed qt slot function return value size max by that amount.
But this should be inconsequential. This does imply that we can't call read with a buffer larger than we're willing to exceed this limit by.
Sets the maximum total article source of unix fuction that can be used for all messages received on this connection. Normally DBusConnection automatically handles all messages to the org. Peer interface. However, the message bus wants to be able to route methods on that interface through the bus and to other applications. If routing peer messages is enabled, then messages qt slot function return value the org. Peer interface that also have a bus destination name set will not be automatically handled by the DBusConnection and instead will be dispatched normally to the application.
