Re: question about gtk_dialog (gtk2)

2018-06-21 Thread Emmanuele Bassi via gtk-app-devel-list
You haven't specified which windowing system you're using. If it's X11, then the position of a window is always the remit of the window manager; the position set is a hint, which is taken into account by the window manager itself, alongside the "this is a dialog" hint that GtkDialog sets.

Use the GdkMonitor API; GdkScreen is an X11-ism, and a single screen can cover multiple outputs. https://developer.gnome.org/gdk3/stable/GdkMonitor.html Ciao, Emmanuele. On Thu, 2 Aug 2018 at 14:58, Wojciech Puchar wrote: > > > On 2018.08.02 15:55, Wojciech Puchar wrote: > > how to get

You probably want to ask on gtk-devel-list and gnome-shell-list. Wayland interfaces need to be implemented by the compositor, and typically not piecemeal. That KDE interface seems to be a private interface shared between Plasma and kwin, like the gtk_shell interface is a private interface between

Do you have an example of how you want to modify the style? Changing the style does not require access to the widget: it requires loading a CSS fragment in your application's startup code, and applying the appropriate selector to match the treeview inside the file chooser dialog. Ciao,
