Window size presetting is not working

No matter if I start it with nvim-qt --geometry 300x200 or nvim-qt --qwindowgeometry 60x10, the window size is always the one of the last closed other nvim-qt window.

I'm using...

    This issue reproduces in v0.2.14, but not v0.2.15. You need this commit: cc2c67891f5525fc463460c9b1c33f127aa54667.

    An upgrade will resolve the issue. Sorry for the break.

    I updated the code:

    10:20:43|facundo:~/sistema/neovim-qt/build (master)$ git rev-parse HEAD

    but opened windows still not being affected by those parameters. I'm executing it like:

    10:20:44|facundo:~/sistema/neovim-qt/build (master)$ bin/nvim-qt --geometry 500x100 --qwindowgeometry 500x100

    Thanks for re-testing!

    From what I can tell: - v0.2.14 -- not working - v0.2.15 -- working, fixed by cc2c67891f5525fc463460c9b1c33f127aa54667 - master -- not working, broken by 847f0271f2af61a35e8676e069a2e8b31a527760

    It looks like the problem lies in:

    NeovimQt::App app(argc, argv);

    The parent constructor, QApplication can modify argc/argv in-place. It will sometimes remove command line arguments! :fearful:

    In this case --geometry is recognized and removed. The removal of the argument prevents m_parser from checking for this scenario, and breaks the fix from cc2c67891f5525fc463460c9b1c33f127aa54667.

    I very much dislike QCommandLineParser and how Qt parses arguments...

    Unrelated thoughts:

    The version output for v0.2.15 is not correct. The CMake constant was not updated for the release.

    It looks like the --version argument could use some additional work. The output for this scenario was not accurate. Instead of NVIM-QT v0.2.14.0, we should output something like NVIM_QT git-eb98732.

    Maybe there is a good way for CMake to automatically generate the version/hash from git?

    Can you test this patch?

    From my tests, we can work around the issue by saving arguments before QApplication clobbers them:

    diff -r ee9766fc4c43 src/gui/main.cpp

    +   for (int i = 1; i < argc; i++)

    +       arguments << argv[i];
    +   }
        NeovimQt::App app(argc, argv);
    -   // Get existing arguments, drop executable, append --nofork.
    -   QStringList new_args{ app.arguments().mid(1) };
    -   new_args.insert(0, "--nofork");
    -   if (!QProcess::startDetached(app.applicationFilePath(), new_args)) {
    +   if (!QProcess::startDetached(app.applicationFilePath(), arguments)) {
            qWarning() << "Unable to fork into background";
            return -1;

    In an ideal world we would have App<{QCoreApplication or QApplication}> app(argc, argv), but Q_OBJECT does not support templates. Inheritance doesn't work well either (multiple inheritance issues).

    I tested the patch; with it both --geometry and --qwindowgeometry (together or separated) work fine.
