我试图为 Gedit 3 编写一个使用 GObject 自省(introspection)的小插件。下面显示的代码的相关部分只是旨在建立一个环境,然后我可以在该环境中适应按钮回调中的函数。但是,按钮的加速器不起作用。
from gi.repository import Gtk, Gedit, GObject
ui_string = """<ui>
<toolbar name="ToolBar">
<separator />
<toolitem name="Test" action="Test" />
</toolbar>
</ui>
"""
class test:
def __init__(self, plugin, window):
self.window = window
self.plugin = plugin
self.ui_id = None
manager = self.window.get_ui_manager()
action_group = Gtk.ActionGroup("TestPluginactions")
action_test_button = Gtk.Action(name="Test",
label="Test",
tooltip="Test",
stock_id=Gtk.STOCK_EXECUTE)
action_test_button.connect("activate", self.testcallback)
action_group.add_action_with_accel(action_test_button, "<Ctrl>l")
manager.insert_action_group(action_group, -1)
self.ui_id = manager.add_ui_from_string(ui_string)
manager.ensure_update()
def deactivate(self):
manager = self.window.get_ui_manager()
manager.remove_ui(self.ui_id)
self.ui_id = None
self.window = None
self.plugin = None
def testcallback(self,unused):
dialog1 = Gtk.MessageDialog(self.window,Gtk.DialogFlags.DESTROY_WITH_PARENT,
Gtk.MessageType.ERROR,Gtk.ButtonsType.OK,"TEST")
dialog1.run()
dialog1.destroy()
class WindowActivatable(GObject.Object, Gedit.WindowActivatable):
window = GObject.property(type=Gedit.Window)
def __init__(self):
GObject.Object.__init__(self)
self.instances = {}
def do_activate(self):
self.instances[self.window] = test(self, self.window)
def do_deactivate(self):
if self.window in self.instances:
self.instances[self.window].deactivate()
最佳答案
知道 GTK 3 有一些错误,它不允许以上面显示的方式将快捷方式分配给工具项。但是菜单项工作正常。所以下面的代码更好。
from gi.repository import Gtk, Gedit, GObject
ui_string = """<ui>
<toolbar name="ToolBar">
<separator />
<toolitem name="Test" action="Test" />
</toolbar>
<menubar name="MenuBar">
<menu name="ToolsMenu" action="Tools">
<placeholder name="ToolsOps_2">
<menuitem name="test1" action="test1"/>
</placeholder>
</menu>
</menubar>
</ui>
"""
class test:
def __init__(self, plugin, window):
self.window = window
self.plugin = plugin
self.ui_id = None
manager = self.window.get_ui_manager()
action_group = Gtk.ActionGroup("TestPluginactions")
action_test_button = Gtk.Action(name="Test",
label="Test",
tooltip="Test",
stock_id=Gtk.STOCK_EXECUTE)
action_test = Gtk.Action(name="test1",
label="Test",
tooltip="Test",
stock_id=Gtk.STOCK_EXECUTE)
action_test_button.connect("activate", self.testcallback)
action_test.connect("activate", self.testcallback)
action_group.add_action(action_test_button)
action_group.add_action_with_accel(action_test, "<Ctrl>l")
manager.insert_action_group(action_group, -1)
self.ui_id = manager.add_ui_from_string(ui_string)
manager.ensure_update()
def deactivate(self):
manager = self.window.get_ui_manager()
manager.remove_ui(self.ui_id)
self.ui_id = None
self.window = None
self.plugin = None
def testcallback(self,unused):
dialog1 = Gtk.MessageDialog(self.window,Gtk.DialogFlags.DESTROY_WITH_PARENT,
Gtk.MessageType.ERROR,Gtk.ButtonsType.OK,"TEST")
dialog1.run()
dialog1.destroy()
class WindowActivatable(GObject.Object, Gedit.WindowActivatable):
window = GObject.property(type=Gedit.Window)
def __init__(self):
GObject.Object.__init__(self)
self.instances = {}
def do_activate(self):
self.instances[self.window] = test(self, self.window)
def do_deactivate(self):
if self.window in self.instances:
self.instances[self.window].deactivate()
关于python - Accel 在 gedit 3 插件中不起作用,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/22594173/
