Can anyone tell me how I can do this; I am trying to debug a problem with user32.dll under the native NT comctl32.?
When drawing a ListView --debugmsg +relay shows three consecutive calls;
SetRect (&rect...) FillRect (00000b04,&rect,00000082 (/* I reckon that is GetStockObject(BLACK_BRUSH)*/) DrawIcon (00000b04,0x40,0x60,hicon,...)
Now as it stands I get random rubbish in the background of the icons (in the region covered by the mask).
If I insert a hack into DrawIcon so that it does a FillRect (b04,the rectangle, GetStockObject (WHITE_BRUSH)) then things work out OK.
(Also, the code seems to draw the icon to four hDCs and I can do the same hack on the second hDC to get the same effect but not the third and fourth).
Firstly I don't understand how it has a chance of working given that it fills the rectangle with a black brush.
So what I want is a way of seeing what the contents of the rectangular region is at the exit from the FillRect and the entrance to the DrawIconEx, based on the hDC. (Something like "give me the pixels of the 32x32 rectangle at this location of this hDC")
Also it seems to me that these two function calls are consecutive, so if anything is changing I guess it would be as a result of code within comctl32 itself. Is there any other way that control can come back into the Wine code between a relay exit and entrance?
