Why QFileDialog::getOpenFileName is not centered?

[ricardo]

Hi friends!

Do you know why QFileDialog::getOpenFileName is shown not centered? When I call it, I pass my QMainWindow derived class pointer, but all my open dialogs are wrong, however, my own dialogs that derive from qdialog, are always centered.

Any idea?

Thanks in advance.

This is strange.
Can you post the piece of your code where you call QFileDialog::getOpenFileName?

[ricardo]

Sure:

void CEditor::OpenLevel() {
QString filename_and_folder=QFileDialog::getOpenFileName(this, "Load Level", QString(LEVELS_FOLDER), "Unprocessed Level (*.xml);;All files (*.*)"); 
...
}

void CEditor::OpenLevel() {
QString filename_and_folder=QFileDialog::getOpenFileName(this, "Load Level", QString(LEVELS_FOLDER), "Unprocessed Level (*.xml);;All files (*.*)"); 
...
}

To copy to clipboard, switch view to plain text mode 

CEditor is derived from QMainWindow

Any idea? Am I missing anythig?

Thanks.

Sorry! The only idea was that the pointer passed as QFileDialog's parent was NULL.

Maybe it's a bug.

Using the debugger, "this" has a correct value.

And I read this on docs
http://doc.trolltech.com/4.5/qfiledialog.html
This function creates a modal file dialog with the given parent widget. If parent is not 0, the dialog will be shown centered over the parent widget.

What's going on? Perhaps because I'm using a static call?

The documentation on QFileDialog::getOpenFileName() says that the method, which is static, uses a native file dialog under Windows and not a QFileDialog.
This native dialog doesn't seem to be able to be opened centred in a Qt application.

Are you telling that it is impossible to show that dialog centered?
It's difficult to believe. Can anyone tell me if he/she is having the same problem?

Thanks.

Doesn't it depend on your system settings? Do dialogs in other applications (non-Qt) open themselves centered above their parents?

I don't know, I don't think so. Is Any Qt expert over there?

Of course, I guess my windows is working nicely.

I just saw that QFileDialog::getOpenFileName(...) uses almost the same file dialog as Windows Notpad.
When using opening a file (menu File -> Open...) the dialog is not centered in Notepad. So the problem lies in Windows itself.

Yes, you are right. But it would be nice to have a flag in order to select if you want to center that dialog, doesn't it? Maybe it is not possible because of Win32 API arquitecture, I don't know.

Does Qt have any list where I can suggest new features?


Thanks.
