C++ Syntax

void

MKI_DrawClear(

HWND f_hWindow );

Clears a dialog window control, i.e. fills it in standard background color for a dialog window.

Parameters

hWindow

[HWND] Handle of the window or control whose client area shall be cleared.

Use this to clear a preview control usually filled using MKI_DrawEntity, MKI_DrawBlock, or MKI_DISPLAYDATA::ControlDrawInit in case there is nothing to display. This will result in the control being filled with dialog background color (instead of drawing window background color), better indicating the "Nothing to draw here" state.
