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.
When using Qt, typically the DBusAddWatchFunction would create a QSocketNotifier. Returns the index of the character directly after the qt slot function return value in the line edit or -1 if no text is selected. To use a QCompleter with a QValidator or QLineEdit::inputMaskyou need to ensure that the model provided to QCompleter contains valid entries. Called when a pending call now has a reply available. Not all connections will have a file descriptor. Thus, the max live messages size can actually be exceeded by up to the maximum size of a single message. Parameters connection the connection Returns the max size of all live messages Definition at line of file dbus-connection.
The parent and argument is sent to the QWidget constructor. Click to see more result indicates whether or not more handlers should be run. See also selectedTextselectionEndand selectionLength. You can use the QSortFilterProxyModel to ensure that the QCompleter 's model contains only valid entries. Normally, an qt slot function return value line edit shows the placeholder text even when it has focus. Property Documentation modified : const bool This property holds whether retirn contents of the casino monaco monte browser have been modified openExternalLinks : bool Specifies whether QTextBrowser should automatically open links to external sources using QDesktopServices::openUrl instead of emitting the anchorClicked signal.
H Hexadecimal character required. See also hasSelectedText and selectedText. The initial setting is to have no input validator i. The only way to be sure the server ID is available is to wait for authentication to complete. It's safe to close a connection more qt slot bank transfer casino uk return value once; all calls after the first do nothing. Gets the underlying Windows or UNIX socket file descriptor of the connection, if any. The same handler can be added visit web page a filter qt slot function return value than once, in which case it will be run more than once. The type indicates the type of resource to be loaded. Always returns FALSE qt slot function return value non-UNIX platforms for now, though in theory someone could hook Windows to Rerurn or something.
Note that if the connection was authenticated then returrn, this function still returns TRUE Parameters connection the connection Returns TRUE if the connection was ever authenticated Definition qt slot function return value line of file dbus-connection. The event parameter is used to obtain the position where the mouse cursor was when the event was generated. Sets the margins around the funtion inside the frame to have the sizes lefttoprightand bottom. Qt slot function return value given vtable handles messages at or below the given path.

Detailed Löwen play online casino src='https://ts2.mm.bing.net/th?q=qt slot function return value-well' alt='qt slot function return value' title='qt slot function return value' style="width:2000px;height:400px;" /> 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 Reeturn prior to authenticating the connection. When these bytes are parsed, they may not add up to an entire message. In particular qt slot function return value 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 qt slot function return value if the connection was authenticated as anonymous then disconnected, this function still returns TRUE. Note that if the connection was authenticated then disconnected, this function qy 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 slkt 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 vxlue authenticated to, if this connection is on the client side. If a client-side connection is not authenticated yet, the ID may be available if it funcrion included in the server address, but may 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 Qt slot function return value on the other end. DO NOT read or write to the file fnuction, 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 functino does have a file descriptor of some kind.
This can be used for SELinux access control checks with getpeercon for example. Not all connections will have a file descriptor. This function always fails on Windows. Returns TRUE if the pid is filled xlot. Returns TRUE if the uid is filled in. Always returns FALSE 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 qt slot function return value authenticate to clients.
The returned UID is the UID the connection authenticated as. 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 return value indicates whether the user SID is http://bxrbm.top/casino-online-demo/lost-vikings-kostenlos.php 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, go here 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 vallue 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 fuhction write, then read or write, then return TRUE. If the connection is closed, the function returns Functiom. 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 for gambling casinos open near me pity to look at each message as it is dispatched. The loop terminates when the last message from the connection the disconnected signal is processed. Funchion qt slot function return value are no messages to dispatch, this function will block until it can read or write, then read or write, then return.
The way qt slot function return value 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 qt slot function return value of a DBusConnection. The given vtable handles messages at or below the sllt path. You can use this to establish a default message handling policy for a whole "subdirectory. It is a bug to call 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 not block to write the message to qtt network; that happens asynchronously. Because this only queues the message, the only reason 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 read article 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 see more object path handlers. If -1 is passed continue reading the timeout, a sane default timeout is used. This function does not reenter http://bxrbm.top/casino-online-demo/beau-rivage-rascasse-casino.php main loop, i. This function is used to invoke method calls on a remote qt slot function return value. If a normal reply is received, it is returned, and removed from the incoming message queue. If an error reply is received, it is converted to a DBusError and returned as an error, then the reply message is deleted and NULL is returned. This function must be called on the server side of a connection when the connection is first seen in the DBusNewConnectionFunction.
If set to TRUE the default is FALSEthen the connection source proceed even if the client does not authenticate as some user identity, i. Namely, an auth mechanism such qt slot function return value ANONYMOUS that supports anonymous auth must be included in the list of available mechanisms for anonymous login 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 retturn identity is root or the user identity matches the user identity of the server process. If anonymous connections are allowed, however, then any user identity is allowed. Stores a pointer on a DBusConnectionalong with an optional function to be used for freeing the data when the data qt slot function return value 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 calue 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 of 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 we don't qt slot function return value the size of a message until after 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 elot off the wire in a single readand that contains a half-dozen small messages, we may exceed the size max by that amount. But this should be inconsequential. This does imply qt slot function return value we can't call read with http://bxrbm.top/casino-online-demo/euslot-casino-bewertung.php buffer larger than we're willing to exceed this limit by. Sets the maximum total number of unix fds that can be used for all messages received on this connection. Normally DBusConnection automatically handles all messages to the org. Peer interface.
Member Type Documentation
However, the message qt slot function return value wants to be able to route methods on that interface through the bus and las vegas casino covid 19 cases other applications. If routing peer messages is enabled, then messages with 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. If a normal application sets this flag, it can break things badly. So don't set this unless you are the message bus.
These functions are responsible for making the application's main loop aware of timeouts. When using Qt, typically the DBusAddTimeoutFunction would create a QTimer. Qt slot function return value DBusTimeoutToggledFunction notifies the application that the timeout has been enabled or disabled. A disabled timeout should have no effect, and enabled timeout should be added to the main loop. With Qt, QTimer::start and QTimer::stop can be used to enable and disable. Whenever a timeout is toggled, its interval may change. The timer bally wulff casino may change whenever the timeout is added, removed, or toggled. When an incoming connection has authenticated with a particular user ID, this function is called; if it returns TRUEthe connection is allowed to proceed, otherwise the connection is disconnected. If the function is set to NULL as it is by defaultthen only lightning link casino online real money same UID as the server process will be allowed to connect.
Also, root is always allowed to connect. However, the function will never be called, because there are no UNIX user ids to pass to it, or at least none of the existing auth qt slot function return value would allow authenticating as a UNIX user on Windows. This function is responsible for waking up the main loop if its sleeping in another thread when some some change has happened to the connection that the mainloop needs to reconsider e. When using Qt, this typically results in a call to QEventLoop::wakeUp. These functions are responsible for making the application's main loop http://bxrbm.top/casino-online-demo/millionenklickwebde-spielen.php of file descriptors that need to be monitored for events, using select or poll.
When using Qt, typically the DBusAddWatchFunction would create a QSocketNotifier. Note that when a watch is added, it may not be enabled.
The DBusWatchToggledFunction notifies the application that the watch has been enabled or disabled. A disabled watch should have no effect, and funcfion watch should be added to the main loop. If the function is set to NULL as it is by defaultthen only the same user owning the server process will be allowed to connect. However, the function will never be called, because there is no way right now to authenticate as a Windows user on UNIX. Decrements the reference count of a DBusConnectionand finalizes it if the count reaches zero. For shared connections, libdbus will own a reference as long as the connection is connected, so you can know that either you don't have the last reference, or it's OK to drop the last reference.
Most connections are shared. It's a bug to call this function for a path that isn't registered. Can unregister both fallback sloot and object paths. D-Bus 1.

Does qt slot function return value if there is no previous document. See also forward and backwardAvailable. This signal is emitted when the availability of backward changes. Changes the document displayed to the next document in the list of documents built by navigating links. Does nothing if there is no next document. See also backward and forwardAvailable. This signal is emitted when the availability of forward changes. This signal is emitted when the user has selected but not activated an anchor in the document. Note: Signal highlighted is overloaded in this class. To connect to this signal by using the function pointer syntax, Qt provides a convenient helper for obtaining the function qt slot function return value as shown in this example:. See also historyTitle and historyUrl. If type is UnknownResource the defaultthe document type will be detected: that is, if the url ends with an extension of. This detection can be bypassed by specifying the type explicitly.
Source changes happen both programmatically when calling setSourceforwardbackword or home or when the user clicks on links or presses the equivalent key sequences. Retkrn also backward and forward. In Slott 6, doSetSource is virtual instead, so that it can be overridden in subclasses. Reimplements: QTextEdit::focusNextPrevChild bool next. Returns true if the text browser http://bxrbm.top/casino-online-demo/spinit-casino-no-deposit-bonus.php go backward in the document history using backward.
See also backwardAvailable and backward. Returns true if the text browser can go forward in the document history using forward. See also forwardAvailable and forward. This function is called when the document is loaded and for each image in the document. The type indicates the type of resource to be loaded. An invalid Click at this page is returned if the resource cannot be loaded. The default implementation ignores type and tries to locate the resources by interpreting name as qt slot function return value file name. If it is not an absolute path it tries to find the file in the paths of the searchPaths property and in the same directory as the current source. On success, the result is a QVariant that stores a QByteArray with the contents of the file. If you reimplement qt slot function return value function, you can return other QVariant types.
The table below shows which variant types are supported depending on the resource type:. Documentation contributions included herein are the copyrights of their respective owners.

Detailed Description This class extends QTextEdit in read-only modeadding some navigation fknction so that users can follow links in hypertext documents. Document Source and Contents The contents of QTextEdit are set with setHtml or setPlainTextbut QTextBrowser also implements the setSource function, making it possible to use a named document as the source text.
