You can have the run-time and development environments for GTK 4.x and GTK 3.x installed simultaneously on your computer. Many applications still use GTK 3, an older stable version of GTK. If you want all programs to use GTK3 instead of GTK2, it won't work, it's a job for the application developers to port their application. If you are a developer, youll want to install dev files that work with your particular system, if youre using say KDE (kubuntu) or Xfce (Xubuntu) or a particular development environment such as Unity, Go, Github, etc. If you want to use GTK3 yourself, compile against that instead GTK2, or use PyGObject instead of PyGTK if you're using Python. You should already have a package installed (with proper dependencies) called libgtk-3-0. To build the latest development version of GTK you can use a tool like JHBuild, or you can rely on meson which will download and build many of the required dependencies as subprojects, if they are not available on your system. GTK3 is installed by default, please don't download and compile from the GTK website. Installing GTK from packages Distribution To build GTK, see the installation guide.įor additional help, the frequently asked questions page is a good starting point. The current stable API version of GTK is 4.0. To build an environment for GTK, install all the dependencies listed below: Dependency To read more about these packages, please refer to the Architecture. the configuration went perfectly well and ended with the message 'Now you must run '/usr/bin/make'. If the application constructor is given the arguments, it will remove the GTK options, except -help-gtk, our handler just never sees them but can still display help for it.In order to install GTK for GNU/Linux and Unix systems, you will need to get the GLib, GObject-Introspection, Pango, Gdk-Pixbuf, ATK and GTK packages to build GTK. gtk-gnutella installation problems I'm trying to install gtk-gnutella and I've hit a road bump. All Linux Mint systems come with a torrent client like transmission installed. FrostWire is supposed to be a gnutella client and also has Linux versions. the argments can be deferred to the run(argc, argv) call (but don't have to. WireShare is another gnutella client with recent updates and an easy to install Linux Deb file, save and double click. Using gtk_get_option_group adds the GTK options (and help) to it, so -help-all really shows all applicable options, and we don't have to rely on gtk_main(argc, argv) to remove the GTK options, i.e. Here's a subclassed application which parses the command line using Glib, and if -gui is present, opens a window and only terminates after the window is closed. My second example was just missing one line: #include Īpp->activate() // signal_command_line().connect( The default handler which is executed when HANDLES_COMMAND_LINE is not given does that automatically. Turns out, the key is calling activate on the application. Sigc::bind(sigc::ptr_fun(on_cmd), app), false) Glib::MainContext::get_default()->iteration(true) This looks very wrong but seems to work?! app->run(win) - lands here again -> stack overflow. Commands to the gtk-gnutella headless instance must be given from the command line shell. The window is being shown again, but of course the loop continues once it's closed, which is the least problem with that code: #include I haven't found a method that simply waits for the main loop to finish, so I crank it manually. So I figured that the command_line handler isn't actually suppposed to return? But the documentation says run starts the main loop. #include Īuto app = Gtk::Application::create(argc, argv, "my.app",Īpp->signal_command_line().connect(sigc::ptr_fun(on_cmd), false) #include Īuto app = Gtk::Application::create(argc, argv, "my.app") īut simply adding the HANDLES_COMMAND_LINE flag destroys that: The window is never shown. This works as expected, exits when the window is closed. not really great with the command line, but i can get around a little. This is why I'm trying to open the window in the command_line signal handler. Gtk-Gnutella is a reliable and efficient Gnutella client, supporting the latest Gnutella protocol, bandwidth limitation (both incoming and outgoing) traffic compression, and advanced search filters among other features. My goal is to parse the command line after GTK removed its options (like -display), but before opening a window, because I want my app to be usable with a CLI-only interface, too, with both variants making use of Glib etc. I'm trying to use GTK's argv-handling, but there seem to be some issues with the main loop. rather than assuming the major version to get the minor version, one can first run something like: dpkg -get-selections grep 'libgtk.bin' which today will likely show gtk2, gtk3, and gtk4, then you can pass those to dpkg -l, for example, dpkg -l libgtk2.
