[Qtce-preview-feedback] QCursor::Pos()

[Maurice Kalinowski]

Hi,

thank you for trying out Qt/WinCE. I do have some questions/comments on 
this topic.

1. What do you mean with not supported? Is it not available as a class 
or do the return values seem useless?

2. We check on compile time if GWES_ICONCURS is defined. This helps us 
specifying if a SDK supports icon cursors and thus if cursor support 
makes sense. If it is not supported we still do not exclude the QCursor 
support unless one compiles for Windows Mobile 6 Standard Edition 
(reason later).

3. In <qtdir>/src/gui/kernel/qcursor_win.cpp line 85 following you can 
see at the code for Windows CE. We simply call the native hook and ask 
for the position of the cursor. If this call returns invalid data, there 
is not much we can do about it.

4. With which mkspec did you compile Qt/WinCE on. Browsing for the 
device has shown that it is supposed to be a Windows Mobile 6 
professional device, thus wincewm60professional-msvc2005 would be the 
perfect match for that.

To explain above issue about Windows Mobile 6 Standard Edition. Though 
GWES_ICONCURS is defined, all symbols to use an icon cursor are missing 
in the provided libraries, thus linking would fail due to incompatible 
header configuration. This was the reason why we considered to exclude 
QCursor support for this configuration (mkspec: wince60standard-msvc2005).

Looking forward to your answers and


Best Regards,
