Qt::WindowStaysOnTopHint is not working

Cesius

Hello everyone,

I need to create a file dialog displayed on top. At first I tried with QFileDialog::getExistingDirectory but I didn't succeed so I changed to:

@
QFileDialog dialog(0, Qt::WindowStaysOnTopHint);
dialog.setOptions(QFileDialog::ShowDirsOnly);
dialog.setFileMode(QFileDialog::Directory);
dialog.setDirectory(QDir::homePath());

if(dialog.exec())
folderPath = dialog.selectedFiles();@

The first time the dialog is displayed on bottom but the following times is displayed on top.

Could someone please explain me why this behaviour? It happens in Windows XP/7/8

Thanks in advance.

which platform did you try. Normally with above code, it should show on top always. What is the sequence in which this dialog is opened ? If it is X11, you may need to pass Qt::X11BypassWindowManagerHint as well.

Hi Dheerendra,

The application is run in a Windows platform. The sequence is the following:

Object A of class 1 is created in main thread and moved to a secondary thread.
The previous object creates object B of class 2 and moves it into the main thread.
Object B creates the file dialog.

I´ve just realised that if I do @setOptions(QFileDialog::DontUseNativeDialog);@

then the dialog is displayed on top.

Does anyone know why is this happening?

Thanks.
