G_signal_connect. You can register a closure with the g_signal_connect family of functions. Connects a gcallback function to a signal for a particular object.
This is similar to g_signal_connect_data(), but uses a closure which ensures that the gobject stays alive during the call to c_handler by temporarily adding a reference count to gobject. Connects a gcallback function to a signal for a particular object. The handler will be called synchronously, after the default handler of the signal.
Gstreamer Does Nothing With This Data Pointer, It Just.
You can register a closure with the g_signal_connect family of functions. These are the top rated real world c++ (cpp) examples of g_signal_connect extracted from open source projects. The basic concept of the signal system is that of the emission of a signal.
The Instance On Which The Signal Is Emitted And Data Will Be Swapped When Calling The Handler.
It is for signals that notify about property change. If closure is a floating reference (see g_closure_sink ()), this function takes ownership of closure. This is useful when calling pre.
It Is Possible For Its Users To Connect At Runtime Any Number Of Callbacks (Implemented In Any.
Signals introduced for a parent type are.

It Is Not For Usual Signals.
If closure is a floating reference (see g_closure_sink ()), this function takes ownership of closure. The basic concept of the signal system is that of the emission of a signal. The basic concept of the signal system is that of the emission of a signal.
The Instance On Which The Signal Is Emitted And Data Will Be Swapped When Calling The Handler.
The first approach is recommended, as the second approach can result in effective memory leaks of the user data if. This is useful when calling pre. Signals introduced for a parent type are.
Connects A Closure To A Signal For A Particular Object.
A user_data parameter is set in the g_signal_connect family functions when a user connects their own signal handler to the signal. Similar to g_signal_connect(), but allows to provide a gclosurenotify for the data which will be called when the signal handler is disconnected and no longer used. The handler will be called synchronously, after the default handler of the signal.
This Can Be Implemented Automatically Using G_Signal_Connect_Data().
You can rate examples to. Connects a gcallback function to a signal for a particular object. It is possible for its users to connect at runtime any number of callbacks (implemented in any.
To Do So, We Use G_Signal_Connect() And Provide The Callback Function To Be Used (Pad_Added_Handler) And A Data Pointer.
Gstreamer does nothing with this data pointer, it just. It is for signals that notify about property change. Connects a gcallback function to a signal for a particular object.
