Dear all I created a child window and I called GUI_Clear() in WM_PAINT of the parent window hoping that it would clear the background of the child window. What happens is the parent window gets cleared leaving a hole in the place where the child window is. Why child window preserves what was drawn by the grandparent? Thanks

Hi Sven Thanks for the quick reply. To answer your question whether there is a specific reason why I want to draw the pixel without WM_PAINT, it is simply because I'd like to draw a simple x-y graph without the overhead of GRAPH widget and to add 'pinch-and-zoom' capability. Hence I created a window in which I drew x-y axes and now I want to start filling the window with x, y data. Simple as that and yet seems not possible? Cheers

Dear all All I want to do is draw a pixel calling GUI_DrawPixel anywhere in the code. It works only in the window WM_PAINT. However every call outside the WM_PAINT isn't drawing any pixels even though I make sure I call WM_InvalidateWindow. Is there some kind a trick I'm misisng? Thanks

Any more info on that please? I would like X axis to start from StartValue and end at EndValue. Thanks

Dear all How to force window to invalidate itself such that it jumps to WM_PAINT? I have been trying to invalidate windows such that a different button is displayed depending which window I find myself in. For example, I have a top window and a bottom window. Inside the top window there are child windows. If I select TopChild1 then different buttons should appear at the bottom window. I managed to get that to work only once. That is thanks to WM_GET_ID with which I communicate from the TopChild1…

Dear all Having this quick question: how to toggle the background colour of a skinned button? Where shall I change the colour: in the WM_NOTIFICATION_RELEASED of the pertinent window callback or in the button skin callback itself? Could you provide a different example than the WIDGET_ButtonRound, please? Thanks

Dear all Thanks very much for the brilliant support. This time I'm wondering if you come across the situation where by selecting an element from a dropdown box, the click impacts the background widgets. I tried disabling and then enabling background window but that is not working either, as shown below. case ID_DROPDOWN: { switch(NCode) { case WM_NOTIFICATION_SEL_CHANGED: { WM_DisableWindow(pMsg->hWin); DROPDOWN_Collapse(pMsg->hWinSrc); WM_EnableWindow(pMsg->hWin); break; } } break; } Any clues?…

Dear all Would you be so kind as to help me understand why number of free blocks increases when number of free bytes decreases, please? I'm updating GUI via GUI_Delay.
