Note for compilition
|
||
|
|
--------------------
|
||
|
|
If you want your own plugin within this source tree
|
||
|
|
don't forget to add the new subdirectory to the plugins' Makefile.am
|
||
|
|
SUBDIRS list and add your Makefile to the list of Makefiles found at
|
||
|
|
about the end of the configure.ac file AC_CONFIG_FILES.
|
||
|
|
The API is currently internal until the API is finalized, so you have
|
||
|
|
to build it in this source tree.
|
||
|
|
|
||
|
|
Some more useful notes on developing plugins:
|
||
|
|
|
||
|
|
Modal Mode
|
||
|
|
----------
|
||
|
|
If you want to display large elements that can be toggled instead of small overlays,
|
||
|
|
you can use wm.begin_modal() to make Gala enter modal mode. In this mode, you'll be
|
||
|
|
able to receive key events and all mouse events will be delivered regardless of the
|
||
|
|
region you have set. Don't forget to call wm.end_modal() and provide an obvious way
|
||
|
|
to exit modal mode for the user, otherwise he will be stuck and can only restart
|
||
|
|
Gala.
|
||
|
|
|
||
|
|
Keybindings
|
||
|
|
-----------
|
||
|
|
To add keybindings, you'll need a gsettings schema. You can take a look at Gala's
|
||
|
|
schema in data/org.pantheon.desktop.gschema.xml for an example. You'll also find
|
||
|
|
how to correctly declare shortcut keys in that file. Once you got this file ready
|
||
|
|
it's pretty easy. Just enable its installation in cmake, the relevant is commented
|
||
|
|
out in this template, and call wm.get_screen().get_display().add_keybinding().
|
||
|
|
The keybinding function takes the name of the shortcut key in your
|
||
|
|
schema, then a GSettings instance for that schema, which can be obtained with
|
||
|
|
'new GLib.Settings("org.pantheon.gala.plugins.my-plugin")', then some flags, for
|
||
|
|
which you can almost always use 0, refer to the vapi for more details, and finally
|
||
|
|
your function as arguments. Its delegate is:
|
||
|
|
|
||
|
|
public delegate void KeyHandlerFunc (Meta.Display display, Meta.Screen screen,
|
||
|
|
Meta.Window? window, X.Event event, Meta.KeyBinding binding);
|
||
|
|
|
||
|
|
So it'd be something like
|
||
|
|
|
||
|
|
void initialize (Gala.WindowManager wm)
|
||
|
|
{
|
||
|
|
[...]
|
||
|
|
var display = wm.get_screen ().get_display ();
|
||
|
|
var schema = new GLib.Settings ("org.pantheon.desktop.gala.plugins");
|
||
|
|
display.add_keybinding ("my-shortcut", schema, 0, my_handler);
|
||
|
|
[...]
|
||
|
|
}
|
||
|
|
void my_handler (Meta.Display display, Meta.Screen screen, Meta.Window? window,
|
||
|
|
X.Event event, Meta.KeyBinding binding)
|
||
|
|
{
|
||
|
|
print ("Shortcut hit! D:");
|
||
|
|
}
|
||
|
|
void destroy ()
|
||
|
|
{
|
||
|
|
wm.get_screen ().get_display ().remove_keybinding ("my-shortcut");
|
||
|
|
}
|
||
|
|
|
||
|
|
Overriding default keybindings
|
||
|
|
------------------------------
|
||
|
|
Libmutter allows you to override exisiting shortcuts, which is a lot easier than
|
||
|
|
adding new ones. All you have to do is:
|
||
|
|
|
||
|
|
Keybinding.set_custom_handler ("shortcut-name", my_handler);
|
||
|
|
|
||
|
|
The signature for my_handler is the same as above.
|
||
|
|
|
||

|

|
---------
|
||
|
|
A great source for exploring the possibilities of mutter's API is scrolling through
|
||
|
|
the mentioned mutter vapi. In some cases you can find documentation on particular
|
||
|
|
functions in the mutter source code. Just grep for their C names.
