[Qt-interest] Strange modal dialog behaviour in Qt 4.6.0 Windows

[Malyushytsky, Alex]

It looks like non-modal dialogs are affected too in similar pattern.
I build 32 bit application under Windows XP 64 bit with MSVC 2005.

Hi ,

Any simple dialog (ui file created in QtDesigner), displayed as modal with exec() ignores size specified in call to ->resize
and is shown full screen if application ( not parent, cause I tried put different parents) is in maximized state.

If application is not maximized it opens as expected with a size specified in resize.

More of that if parent is maximized and I double click dialog title it makes it smaller (not the size specified in resize).
If I close dialog now and open again it will be opened and resized correct size.
If I make application window get maximized ( restore and maximize again for example) and dialog is opened it will be shown in full screen again.

This did not happen in Qt 4.5.2 - last version I used before 4.6.0.
I expect this being a bug, but since I am not using the latest version and switching to one takes time to me,
I am trying to see if anybody else seen similar behavior?
Anybody has any comments?

QDialog instance is constructed as below:

        Ui_OptionsDialog ui;
        QDialog dlg (this);
        ui.setupUi ( &dlg );

        if ( dlg.exec( ) == QDialog::Accepted )
        {
                ;
        }

Ui file is any simple uio file I put 1 resizable control and add it to layout, auto-generated setupUi has call to resize which is called (verified under debugger) :

    void setupUi(QDialog *OptionsDialog)
    {
        if (OptionsDialog->objectName().isEmpty())
            OptionsDialog->setObjectName(QString::fromUtf8("OptionsDialog"));
        OptionsDialog->resize(548, 227);
        QIcon icon;
........
