Well, it's been a requirement since forever that you put $DEVPREFIX/bin in your path before invoking jhbuild, but I suppose there's no harm in also adding it with jhbuild to prevent path pollution. I hadn't noticed ~/.pythonversion. That's rude of them, I'll look for a way to bury that

Hello all, and thank you for your great work in the GLib library, and the entire GTK ecosystem! :) I am facing an issue, where it seems I am not deallocating correctly an UNIX signal source. I use my_state->unix_signals_src = g_unix_signal_source_new(SIGINT);

missing documentation about how to draw a window

I was browsing gtk.org in the hope to find a guide about how application developers are supposed to manage the contents of the windows they are about to draw in their applications. Unfortunately I found no guidance about that. Lets take the window where I type this email right now for example.

Re: Changing font of GtkSourceView changes font of GtkSourceMap

I haven't played with the FontMap but was thinking of going the route of using CSS. That, in itself, is a bit of a hassle as I can't seem to find a way to convert a PangoFontDescription to CSS but there are some patches that I found online that should help. On Fri, Mar 1, 2019 at 7:16 PM Reuben

Hello, Yes, g_desktop_app_info_search() is exactly what I need. I will test it later. Thanks a lot for your help. // Moma tito-wolit escreveu no dia segunda, 4/03/2019 à(s) 06:59: > > > On 3/3/19 9:53 PM, Osmo Antero wrote: > > Hello Tito, > > Muito obrigado. > > Thank you, the call with

Re: Finding .desktop file and application info

Btw: Totem (GNOME `s Video Player) has very similar problem. It «lies» about its .desktop file name. It says "totem" instead of "org.gnome.Totem". My app asks for it via DBus/MPRIS2 and gets wrong data. $ locate -i totem | grep ".desktop" /usr/share/applications/org.gnome.Totem.desktop It is

Hello, I have an application that uses g_desktop_app_info_new() function to find GDesktopAppInfo. I just wonder why the g_desktop_app_info_new() FAILS to find the GDesktopAppInfo if the .desktop file is in a sub directory under usr/share/applications/. So this fails: GDesktopAppInfo *app_info =

Re: Gtk::Widget::is_mapped ()

No, it's not. The issue is not GTK: it's the windowing system. With the advent of compositing, all windows are "visible" all the time, from a toolkit perspective. The compositor is responsible for building what's presented to the user. For example: are windows fully visible when doing an
