MGL_wmUpdateDC

Updates invalidated parts of window manager's DC.

Declaration

void MGLAPI MGL_wmUpdateDC(
winmng_t *wm)

Prototype In

mgraph.h

Parameters

wm | the window manager

Description

This function updates the device context by redrawing all areas previously invalidated by either explicit calls to MGL_wmInvalidateXXX functions or by operations that modify visual appearance of windows (such as MGL_wmSetWindowPosition, MGL_wmShowWindow or MGL_wmRaiseWindow).

Painter callbacks attached to windows are used to do actual painting.

Note: A typical application will run in event loop and repeatedly call EVT_halt, MGL_wmProcessEvent and MGL_wmUpdateDC.

Note: This function automatically hides mouse pointer if neccessary to avoid occurence rendering artifacts.
