wait, is something wrong where, a can´t reproduce again... return the issue to me. |
|
|
Please try adding back DCX_CACHE in the call to GetDCEx and let me know if this helps. |
|
|
Ah ok |
|
|
Hi, the error occurs again, using DCX_CACHE the menus are wrong painted I produced the video to show whats happen in the two situations http://giro.no-ip.info:8000/JVMenuError/JVMenuError.html |
|
|
Can you tell me if it works with the very latest SVN version? |
|
|
Using the revision 11747 (last at moment), and patching file on 0004352 the problem continues... can i help with some more information ? ps.: its possible get a commit user on SVN to help on small implementations ? |
|
|
I build a executable on my machine and does not work (same message "Canvas does not allow drawing") then i copy the same executable to another machine using XP too, and the message doesn't appear. After removing the implementation on JVMenus lines 3688~3705 that work in the two machines... source removed: DC := GetDCEx(CanvasWindow, 0, (*DCX_CACHE or *)DCX_WINDOW); try if not Assigned(FBorderCanvas) then begin LastError := GetLastError; if (DC = 0) and (LastError = ERROR_SUCCESS) then FBorderCanvas := TJvDesktopCanvas.Create else FBorderCanvas := TControlCanvas.Create; FBorderCanvas.Handle := DC; end; if FBorderCanvas.Handle <> DC then FBorderCanvas.Handle := DC; DrawBorder(FBorderCanvas, WRect); finally ReleaseDC(CanvasWindow, DC); end; |

Yes, but removing this you no longer have the borders. However, I think you can solve the problem by putting back the code then remove this if (DC = 0) and (LastError = ERROR_SUCCESS) then FBorderCanvas := TJvDesktopCanvas.Create else FBorderCanvas := TControlCanvas.Create; and replace with this FBorderCanvas := TJvDesktopCanvas.Create; That should solve the problem on both your machines. |
|
|
yes, thats works in all machines, you can commit this changes ? |
|
|
The changes are now in SVN |
