Member Function Documentation

◆ activateDrawingContext()

GHOST_TSuccess GHOST_ContextWGL::activateDrawingContext ( )

overridevirtual

Activates the drawing context of this window.

Returns: A boolean success indicator.

Implements GHOST_Context.

◆ getSwapInterval()

GHOST_TSuccess GHOST_ContextWGL::getSwapInterval ( int & intervalOut )

overridevirtual

Gets the current swap interval for swapBuffers.

Parameters

intervalOut Variable to store the swap interval if it can be read.

Returns: Whether the swap interval can be read.

◆ releaseDrawingContext()

GHOST_TSuccess GHOST_ContextWGL::releaseDrawingContext ( )

overridevirtual

Release the drawing context of the calling thread.

Returns: A boolean success indicator.

◆ releaseNativeHandles()

GHOST_TSuccess GHOST_ContextWGL::releaseNativeHandles ( )

overridevirtual

Removes references to native handles from this context and then returns

Returns: GHOST_kSuccess if it is OK for the parent to release the handles and GHOST_kFailure if releasing the handles will interfere with sharing

overridevirtual

Sets the swap interval for swapBuffers.

Parameters

interval The swap interval to use.

Returns: A boolean success indicator.
