mainLoop

Enter the GLUT event processing loop; it will call as necessary any callbacks that have been registered. This routine should be called at most once in a GLUT program.

main event loop, and events

A main event loop abstraction.

The GMainLoop struct is an opaque data type representing the main event loop of a GLib or GTK application.

Memory-managed wrapper type.

Checks to see if the main loop is currently being run via mainLoopRun.

Create a new MainLoop.

Stops a MainLoop from running. Any calls to mainLoopRun for the loop will return.

Runs a main loop until mainLoopQuit is called on the loop. If this is called for the thread of the loop's MainContext, it will process events from the loop, otherwise it will simply wait.

Returns the MainContext of loop.

Creates a new MainLoop structure.

Stops a MainLoop from running. Any calls to mainLoopRun for the loop will return. Note that sources that have already been dispatched when mainLoopQuit is called will still be executed.

Increases the reference count on a MainLoop object by one.

Runs a main loop until mainLoopQuit is called on the loop. If this is called for the thread of the loop's MainContext, it will process events from the loop, otherwise it will simply wait.

Decreases the reference count on a MainLoop object by one. If the result is zero, free the loop and free all associated memory.

(freeglut only) Process one iteration's worth of events in its event loop. This allows the application to control its own event loop and still use the GLUT package.

Return from mainLoop when any window is closed.

Code to run after the listening socket is ready but before entering the main event loop. Useful for signaling to tests that they can start running, or to drop permissions after binding to a restricted port. Default: do nothing. Since 2.1.0

(freeglut only) Stop the event loop. If actionOnWindowClose contains Exit, the application will exit; otherwise control will return to the function which called mainLoop. If the application has two nested calls to mainLoop and calls leaveMainLoop, the behaviour is undefined. It may leave only the inner nested loop or it may leave both loops. If the reader has a strong preference for one behaviour over the other he should contact the freeglut Programming Consortium and ask for the code to be fixed.
