[Qt-interest] Does Qt::WindowModal works on windows XP?

[techsgin]

Hi Acenes

Many thank for your time and effort.

It is a bug of Qt 4.4.0 commercial. 
When using Qt 4.4.5 snapshot the behavior is as expected. :)

Our configuration:

- Window XP Professional, all fixes installed
- Qt 4.4.5 snapshot
- VS2005 Professional

Regards
TechSgin

With this configuration:

- Window XP Home, all fixes installed
- Qt 4.4.3 commercial
- VS2005 Professional

Everything works as expected for true Qt widgets and dialogs, I can switch 
to and use other independant windows in the same application while the 
window modal dialog is shown.

However for native windows dialogs (file, print) the behaviour is as you 
describe.

Hope this helps.

Hi All, and thanks in advance.

This is a bit urgent for us.

According to the help (Qt Assistant)

Qt::WindowModal -
The window is modal to a single window hierarchy and blocks input to its 
parent window, all grandparent windows, and all siblings of its parent and 
grandparent windows.
Qt::ApplicationModal -
The window is modal to the application and blocks input to all windows.

Well I have successfully used many times Qt::ApplicationModal, but never 
Qt::WindowModal.

Our pseudo code goes like this.

We have two top level windows (Documents) with no parents, Lets call them 
"window one" and "window two".

Window one creates a QDialog:

QDialog* createWindowModalDialog()
{
      QDialog *lMyDialog = new QDialog(this);

      lMyDialog->setWindowModality(Qt::WindowModal);

      connect(lMyDialog, SIGNAL(finished(int)), this, 
SLOT(sltChildFinished(int)));

      lMyDialog->show();
      return lMyDialog;
}

Now accurding to the ducomentation, I should be able to access "window two" 
and continue with my work on it, but I cant!!!! hmmmm

Am I doing something wrong? Is it a bug?

*There is also a weird behavior in the taskbar when I activte "window two" 
it gets the focus but it is still frozen.

Thanks
TechSgin
