copied!<p>Ubuntu uses <a href="http://en.wikipedia.org/wiki/GConf" rel="nofollow noreferrer">GConf</a> to store settings. It looks like Windows registry. <a href="http://www.howtogeek.com/howto/ubuntu/assign-custom-shortcut-keys-on-ubuntu-linux/" rel="nofollow noreferrer">Those keys</a> are for storing global shortcuts. To set up global keybingings you should deal with GTK. So install those packages:</p> <p><img src="https://i.stack.imgur.com/PpOHU.png" alt="App Centre"></p> <p>And add to your <code>.pro</code> file following lines:</p> <pre><code>INCLUDEPATH += /usr/include/gconfmm-2.6\ /usr/include/glibmm-2.4\ /usr/lib/glibmm-2.4/include\ /usr/include/glib-2.0\ /usr/lib/glib-2.0/include\ /usr/include/sigc++-2.0\ /usr/lib/sigc++-2.0/include\ /usr/include/gconf/2 LIBS += -L/usr/lib -lgconfmm-2.6 </code></pre> <p>then you need to create new <code>.cpp</code> file or class besause you can't include Qt and GTK headers in the same file. </p> <pre><code>#include <gconfmm.h> using namespace Gnome; </code></pre> <p>and the main part:</p> <pre><code>Conf::init(); try { Glib::RefPtr<Conf::Client> pointer(Conf::Client::get_default_client()); pointer->set("/apps/metacity/keybinding_commands/command_2",Glib::ustring("gedit")); pointer->set("/apps/metacity/global_keybindings/run_command_2",Glib::ustring("<Control><Alt>e")); } catch(Conf::Error error) { std::cerr << "Error code: " << error.code(); } </code></pre> <p>You can use all predefined keys instead of <code>command_2</code> (there are <code>command_screenshot</code>, for example) and you can create your own keys such as</p> <pre><code>/apps/metacity/keybinding_commands/command_textedit /apps/metacity/global_keybindings/run_command_textedit </code></pre> <p>but you also need to set up schemas for your custom keys (I don't know how to do it, I'm new to GTK). After code is executed shortcuts work well.</p>
