This plugin allows you to create multiple edit points in the document by which you can simultaneously edit your document at multiple places. Addition of bottom panel should also be done in do_activate.We recently landed a new gedit plugin in the gedit-plugins module named ‘multi-edit’. You will need to learn to read the C documentation for Gnome Libraries, because Python Documentation is out-dated and incomplete.
It may be a little hard to understand for those new to Gtk. Now because gedit is a single window application, but it creates the menu in appmenu, we have to first create AppActivatable. Gtk supports app-menu(which is available for all windows) and window-menu(which is defined for each window).
However weird it may seem here, gui for menu is created in Gedit.AppActivatable while action is defined in Gedit.WindowActivatable. set_text ( "" ) # this is called every time the gui is updatedĭef do_update_state ( self ): # if there is no document in sight, we disable the action, so we don't get NoneException add_action ( action ) def action_cb ( self, action, data ): # On action clear the document.ĭoc = self. SimpleAction ( name = 'clear_document' ) action. It has the power to give us the active document so that we can clear it.ĭef _connect_menu ( self ): action = Gio. It’s now clear why we used WindowActivatable. As soon as activate is fired, action_cb is called. That’s how signals (similar to events) are used in Gtk. We will connect the action to a callback function. Here we connect to the menu and define the action of clearing the document. Gedit.WindowActivatable: We need to create a WindowActivatable class too. set_accels_for_action ( "win.dictonator_start", ()) self. set_accels_for_action ( "win.clear_document", ( "1", None )) #call me in do_deactivateĭef _remove_menu ( self ): # removing accelerator and destroying menu items menu_item ) # Setting accelerators, now our action is called when Ctrl+Alt+1 is pressed. new ( "Clear Document", 'win.clear_document' ) menu. extend_menu ( "tools-section" ) # This is the submenu which is added to a menu item and then inserted in tools menu. Let us create an example plugin which instantly clears the document.ĭef _build_menu ( self ): # Get the extension from tools menu When a plugin is activated, all “activate” methods from the extension points will be called, and when the plugin is deactivated the “deactivate” methods from all extension points will be called. Like removing trailing whitespaces on document save.ĭo_activate is called in the extension point when gedit object of its defined type is created.ĭo_deactivate is called in the extension point when gedit object of its defined type is destroyed.ĭo_update_state is called in the extension point when gedit object of its defined type needs a UI update.Įxample: _activate is called when a window object is created. When operations on all views are required. Should be used when you want to change/delete/create tabs, to access bottom bar, etc. Provides do_activate, do_deactivate, do_update_state. Gedit usually only runs one instance, even if you launch it several times hence, you can get application menu extension, or can initialize singleton objects using this interface. Refer to the following list to know which interface should be used and when: These define the entry points in your code.Īll extension points will have the defined gedit object as a property.Įxample: Extension point from gedit.AppActivatable will have app property and hence would be able to use Gedit.App API. Each extension is derived from GObject.Object and must implement one of the interfaces that gedit provides for the extension points. This section will try to explain how gedit plugins work.Ī Python plugin will be able to have one or more extensions. It can also be a python package.īoth files are placed in either /usr/lib/gedit/plugins/ (system-wide) or ~/.local/share/gedit/plugins/ (single-user). It tells gedit where the plugin is found. This is a comprehensive guide on writing plugins for gedit in Python3.
