Problem changing background of a child QWidget in Qt 4.1.X

[jpn]

Is there any way of adding some type of conditional compile statement into the code which recognizes Qt 4.0.X versus Qt 4.1.3? I would like to have the code maintain backward compatability (transparently if possible) with older revisions of Qt 4.0.X or higher.

I am still having the same problem with QFrame changing the background color.

I am using Qt 4.1.1 with Visual Studio .NET 2003.
It works perfectly fine with Visual Studio 6.0.

Has anybody seen this?

I am using Qt 4.1.1 with Visual Studio .NET 2003.
It works perfectly fine with Visual Studio 6.0.

Do you use the same Qt version with both of these toolchains?

[newby]

Yes. I am using the same Qt 4.1.1 with both Visual Studio .NET 2003 and Visual Studio 6.0

It displays the correct color when the child QFrame is selected with mouse click or all children QFrames are selected.

It displays the correct color when the child QFrame is selected with mouse click or all children QFrames are selected.

Does it work when you start your application like this:

C:...\> app.exe -style plastique

or

C:...\> app.exe -style windows

?

[newby]

Yes. It works with both those styles.

[jacek]

Yes. It works with both those styles.

So most likely the problem lies in QWindowsXPStyle. Try a newer Qt version to see if the problem was fixed.
