Platform Package reference: Function EwDoneViewport()

Description of the function EwDoneViewport() available in all Platform Packages for C compatible target systems. This function is intended to be used when integrating the Embedded Wizard created GUI application with the underlying graphics subsystem, graphics hardware or other external GUI applications coexisting on the same system.

Declaration

void EwDoneViewport( XViewport* aViewport )

Parameters

aViewport

Viewport to deinitialize.

Discussion

The function EwDoneViewport() deinitializes the given viewport. If necessary the previously created framebuffers are hidden and associated video memory is released. Usually, the function is called at the shutdown time during the Deinitialization of the GUI Application. To initialize a viewport the function EwInitViewport() is available.
