Allow focus on window when file opened

[ghost]

In most applications where opening a file creates a new tab in an existing window (e.g. Chrome, Firefox) the window is brought to focus. Using retext 8.0.0 with Linux Mint 21 Cinnamon, when Retext is already open in a window that does not have focus, opening a Markdown file results in its being opened in a new tab in the Retext window, and the Retext icon in the desktop panel is highlighted, but the window is not brought to focus.

I would request that there be an item in the preferences dialog allowing the user to specify the Retext window should be brought to focus whenever a file is opened.

We do have this line, which is supposed to raise the window to the top of the window manager's stack.

retext/ReText/__main__.py

Line 121 in 0987c28

qWidgetIface.call('raise')

However, for some reason this does not happen. Maybe the window manager protects you from the aggressive windows and only highlights them, instead of actually raising.

I tried other Qt's methods such as activateWindow() and setWindowState() but none of them or their combinations has the needed effect with my window manger (Metacity). I also read about some hacks such as marking the window as top-level (and unmarking again), or showing and hiding a message box, but such methods look too ugly for me.

Advices how to better implement it are welcome.
