MUIPaintBackground¶

MUIPaintBackground, hWin:MUIWND, Backcolor:MUICOLORRGB, BorderColor:MUICOLORRGB

Paint the background of the a window a specified COLORREF color. Optionally provide BorderColor for a border COLORREF color to draw. If BorderColor = 0, no border is drawn. If you require black for border, use 1, or MUI_RGBCOLOR(1,1,1)

Parameters

[in] hWin - handle to window to paint background for
[in] Backcolor - color to paint background with
[in] BorderColor - color to paint border with

Return

None

Notes

You should handle the WM_ERASEBKGND and WM_PAINT events if you are going to use this function.

If you are using this on a window/dialog that does not use the ModernUI_CaptionBar control AND window/dialog is resizeable, you should place a call to InvalidateRect in the WM_NCCALCSIZE handler to prevent ugly drawing artefacts when border is drawn whilst resize of window/dialog occurs.

The ModernUI_CaptionBar handles this call to WM_NCCALCSIZE already by default

Here is an example of what to include if you need:

.ELSEIF eax == WM_NCCALCSIZE
   Invoke InvalidateRect, hWin, NULL, TRUE

Example

.ELSEIF eax == WM_ERASEBKGND
   mov eax, 1
   ret

.ELSEIF eax == WM_PAINT
   Invoke MUIPaintBackground, hWin, MUI_RGBCOLOR(255,255,255), MUI_RGBCOLOR(48,48,48)
   mov eax, 0
   ret
