Hi all,

I have the following problem with dialogs on the Mac.

I have a main window/dialog and I am opening a modeless dialog, I need to have both the main window/dialog and the modeless dialog visible at the same time.
I create the modeless dialog as simple as this

QDialog* myDialog = new QDialog(this);
[...]
myDialog->show();
myDialog->raise();
myDialog->activateWindow();

The problem I'm having is that if I click on the main window then the dialog disappears behind the main application window.
The workaround I've found is to create the dialog as a tool dialog. In that case the dialog stays always on top of the main application window, but there are some issues with the modeless dialog default button rendering when the dialog loses focus as visible in the following image where the default button in the first one.

I created a very sample application that opens both a "standard" dialog and a tool dialog, here are both issues in a screenshot

The standard dialog is behind the main application, while the tool dialog default button is not properly rendered when the tool dialog loses focus.

Is there any workaround? Is this a Qt bug?
Attached is the code for the above example.
The example works fine on windows, with both types of dialogs.
