Ubuntu – The window of a Window’s program running under Wine is not in the front by default

Ubuntuwine

I Often run a program to open a file from terminal, and I just want to take a quick look at the file in the program without clicking the program's window, and then close the program by Ctrl–F4 which requires the program's window is in the front i.e. in the focus by default.

  • If the program is native Linux's one, the program's window is always in front i.e. in focus by default, so I can just close the program by Ctrl–F4.

  • If the program is a Windows' one running under Wine, the program's window is not in the front, i.e. not in focus by default. The program which is in the front is the terminal from which the program is started. I often forget that, and accidentally close the terminal instead of the program by Ctrl–F4. Closing the terminal will close the program as well, but does more than what I want to.

So my question is: how can I make a Windows' program to run in the front by default?

Note:

  1. You can test the above by opening a pdf file with Windows' program PDFXCview.exe under Wine 2.0.1, and with native linux's program evince. I am running them under Ubuntu 16.04.

  2. I run the Windows' program to open a file under wine in terminal by

    wine /home/tim/path/to/PDFXCview.exe myfile.pdf

    and the program's window is not in the front by default.

    Strangely, if I run the program without opening any file by

    wine /home/tim/path/to/PDFXCview.exe

    the window of the program will be in the front by default.

  3. One thing that might or might not be related is that I have set up
    to use PDFXCview.exe to open pdf files from file manager PcManFM in
    LXDE, by adding to ~/.local/share/applications/mimeinfo.cache:

    application/pdf=wine-extension-pdf.desktop;userapp-PDFXCview.exe-NHNW1Y.desktop;

    where the content of the file
    ~/.local/share/applications/userapp-PDFXCview.exe-NHNW1Y.desktop
    is

    [Desktop Entry]
Type=Application
Name=PDFXCview.exe
Exec=wine /home/tim/path/to/PDFXCview.exe %U
Categories=Other;
NoDisplay=true
MimeType=application/pdf
Terminal=false

    It might not be related because it is a setup for running programs
    from desktop environment, while my question is about running
    programs from terminal.

    When I open a pdf file using PDFXCview.exe under wine from PcManFM, by double clicking the file in PcManFM, the window of PDFXCview.exe is not in the front either. See https://askubuntu.com/q/925540/1471

Thanks.

First note that foreground-window and window-with-keyboard-focus are not the same thing. They are for Mircosoft's Windows, and for a lot of window managers, but not necessarily. For example KDE can manage these two properties separately.

Now about your question, like the point I made above, it will depend on the window manager. In Kde there are setting that allow you to control keyboard focus, even settings that depend on the application (but still part of the window manager). enter image description here The above image shows how to do the opposite (set accept focus to yes to do what you are asking for). I tested this configured for one application.

Do not mix up the role of window-manager, launcher etc. Both KDE, Gnome, LXDE and others do all of these. The window manager manages which windows are where, there size, whether they are minimise, which one are behind which, which has keyboard focus. The application can also control this, and so can another application, but ultimately it is the process that is registered as the window manager, that is in charge. It can block other processes from doing these things, and decides where a window is mapped, and whether it gets keyboard focus, when first mapped (or ever). The only visible part of the window manager is the title bar(+close, maximise, minimise etc icons) of all of the other windows.
