PyGObject - 状态图标上的左键单击菜单

发布于 2024-11-25 15:43:47 字数 425 浏览 3 评论 0原文

我开始为 Gnome 编写一个小面板小程序，我希望用户能够左键单击状态图标来查看一些选项和信息，例如类似于 Gnome 3 中的声音图标，您可以在其中设置音量通过左键单击，同时通过右键单击设置首选项。右键单击代码如下：

statusicon.connect("popup-menu", right_button_click)

其中 right_button_click 是在右键单击事件上调用的函数的名称。重要的部分是 "popup-菜单”。设置左键单击事件的替代方法是什么？

I'm starting to write a small panel applet for Gnome and I'd like the user to be able to left-click on the status icon to see some options and information e.g. similar to sound icon in Gnome 3, where you can set volume via left-click while set preferences via right-click.
Right-click code is this:

statusicon.connect("popup-menu", right_button_click)

where right_button_click is the name of the function that gets called on right-click event. The important part is "popup-menu". What would be alternative for setting left-click event?

这是一个展示其工作原理的小例子。

#!/usr/bin/python3

import gi
gi.require_version('Gtk', '3.0')

from gi.repository import Gtk

class TrayIcon(Gtk.StatusIcon):
    def __init__(self):
        Gtk.StatusIcon.__init__(self)
        self.set_from_icon_name('help-about')
        self.set_has_tooltip(True)
        self.set_visible(True)
        self.connect("popup_menu", self.on_secondary_click)


    def on_secondary_click(self, widget, button, time):
        menu = Gtk.Menu()

        menu_item1 = Gtk.MenuItem("First Entry")
        menu.append(menu_item1)

        menu_item2 = Gtk.MenuItem("Quit")
        menu.append(menu_item2)
        menu_item2.connect("activate", Gtk.main_quit)

        menu.show_all()
        menu.popup(None, None, None, self, 3, time)

if __name__ == '__main__':
    tray = TrayIcon()

    Gtk.main()

This is the tiny example showing how it works.

#!/usr/bin/python3

import gi
gi.require_version('Gtk', '3.0')

from gi.repository import Gtk

class TrayIcon(Gtk.StatusIcon):
    def __init__(self):
        Gtk.StatusIcon.__init__(self)
        self.set_from_icon_name('help-about')
        self.set_has_tooltip(True)
        self.set_visible(True)
        self.connect("popup_menu", self.on_secondary_click)


    def on_secondary_click(self, widget, button, time):
        menu = Gtk.Menu()

        menu_item1 = Gtk.MenuItem("First Entry")
        menu.append(menu_item1)

        menu_item2 = Gtk.MenuItem("Quit")
        menu.append(menu_item2)
        menu_item2.connect("activate", Gtk.main_quit)

        menu.show_all()
        menu.popup(None, None, None, self, 3, time)

if __name__ == '__main__':
    tray = TrayIcon()

    Gtk.main()

首先是查看音量控制的 gnome 代码，那就是这个
其次，您应该查看 GtkStatusIcon 的 API 文档，此处
那应该足够了。

这是一个迟到的回复，但我只是发布此内容，以防其他人寻找对 gtkstatusicon 的左键单击控制。

直接的替代方案是

statusicon.connect("activate", left_button_click)

这是托盘图标弹出菜单的示例，使用左键单击而不是（常见的）右键单击。

#!/usr/bin/env python
import pygtk
pygtk.require('2.0')
import gtk

class TrayIcon(gtk.StatusIcon):
    def __init__(self):
        gtk.StatusIcon.__init__(self)
        self.set_from_icon_name('help-about')
        self.set_has_tooltip(True)
        self.set_visible(True)
        self.connect("activate", self.on_click)

    def greetme(self,data=None):  
        msg=gtk.MessageDialog(None, gtk.DIALOG_MODAL,gtk.MESSAGE_INFO, gtk.BUTTONS_OK, "Greetings")
        msg.run()
        msg.destroy()

    def on_click(self,data): 
        event=gtk.get_current_event()
        btn=event.button #this gets the button value of gtk event.
        time=gtk.get_current_event_time() # required by menu popup. 

        menu = gtk.Menu()
        menu_item1 = gtk.MenuItem("First Entry")
        menu.append(menu_item1)
        menu_item1.connect("activate", self.greetme)

        menu_item2 = gtk.MenuItem("Quit")
        menu.append(menu_item2)
        menu_item2.connect("activate", gtk.main_quit)

        menu.show_all()
        menu.popup(None, None, None, btn, time) 
        #button can be hardcoded (i.e 1) but time must be correct.

if __name__ == '__main__':
    tray = TrayIcon()
    gtk.main()

另外，还有一个替代方案：

statusicon.connect("button-press-event", button_click)

下面的示例代码在右键和左键单击中都会在 gtktrayicon 中引发相同的弹出菜单。

#!/usr/bin/env python
import pygtk
pygtk.require('2.0')
import gtk

class TrayIcon(gtk.StatusIcon):
    def __init__(self):
        gtk.StatusIcon.__init__(self)
        self.set_from_icon_name('help-about')
        self.set_has_tooltip(True)
        self.set_visible(True)
        self.connect("button-press-event", self.on_click)

    def greetme(self,data=None):  
        msg=gtk.MessageDialog(None, gtk.DIALOG_MODAL,gtk.MESSAGE_INFO, gtk.BUTTONS_OK, "Greetings")
        msg.run()
        msg.destroy()

    def on_click(self,data,event):
    #event in this case is sent by the status icon connect. 
        btn=event.button 
        #By controlling this event.button value (1-2-3 for left-middle-right click) you can call other functions.
        time=gtk.get_current_event_time() # required by the popup. 

        menu = gtk.Menu()
        menu_item1 = gtk.MenuItem("First Entry")
        menu.append(menu_item1)
        menu_item1.connect("activate", self.greetme) 

        menu_item2 = gtk.MenuItem("Quit")
        menu.append(menu_item2)
        menu_item2.connect("activate", gtk.main_quit)

        menu.show_all()
        menu.popup(None, None, None, btn, time) 

if __name__ == '__main__':
    tray = TrayIcon()
    gtk.main()

希望上面的代码有帮助。

This is a late response, but i'm just posting this in case someone else ever looks for left click control over gtkstatusicon.

The direct alternative is

statusicon.connect("activate", left_button_click)

This is a sample for trayicon popup menu working with left click instead of the (common) right click.

#!/usr/bin/env python
import pygtk
pygtk.require('2.0')
import gtk

class TrayIcon(gtk.StatusIcon):
    def __init__(self):
        gtk.StatusIcon.__init__(self)
        self.set_from_icon_name('help-about')
        self.set_has_tooltip(True)
        self.set_visible(True)
        self.connect("activate", self.on_click)

    def greetme(self,data=None):  
        msg=gtk.MessageDialog(None, gtk.DIALOG_MODAL,gtk.MESSAGE_INFO, gtk.BUTTONS_OK, "Greetings")
        msg.run()
        msg.destroy()

    def on_click(self,data): 
        event=gtk.get_current_event()
        btn=event.button #this gets the button value of gtk event.
        time=gtk.get_current_event_time() # required by menu popup. 

        menu = gtk.Menu()
        menu_item1 = gtk.MenuItem("First Entry")
        menu.append(menu_item1)
        menu_item1.connect("activate", self.greetme)

        menu_item2 = gtk.MenuItem("Quit")
        menu.append(menu_item2)
        menu_item2.connect("activate", gtk.main_quit)

        menu.show_all()
        menu.popup(None, None, None, btn, time) 
        #button can be hardcoded (i.e 1) but time must be correct.

if __name__ == '__main__':
    tray = TrayIcon()
    gtk.main()

Also , there is this alternative :

statusicon.connect("button-press-event", button_click)

Bellow sample code raise the same popup menu in gtktrayicon in BOTH right and left click.

#!/usr/bin/env python
import pygtk
pygtk.require('2.0')
import gtk

class TrayIcon(gtk.StatusIcon):
    def __init__(self):
        gtk.StatusIcon.__init__(self)
        self.set_from_icon_name('help-about')
        self.set_has_tooltip(True)
        self.set_visible(True)
        self.connect("button-press-event", self.on_click)

    def greetme(self,data=None):  
        msg=gtk.MessageDialog(None, gtk.DIALOG_MODAL,gtk.MESSAGE_INFO, gtk.BUTTONS_OK, "Greetings")
        msg.run()
        msg.destroy()

    def on_click(self,data,event):
    #event in this case is sent by the status icon connect. 
        btn=event.button 
        #By controlling this event.button value (1-2-3 for left-middle-right click) you can call other functions.
        time=gtk.get_current_event_time() # required by the popup. 

        menu = gtk.Menu()
        menu_item1 = gtk.MenuItem("First Entry")
        menu.append(menu_item1)
        menu_item1.connect("activate", self.greetme) 

        menu_item2 = gtk.MenuItem("Quit")
        menu.append(menu_item2)
        menu_item2.connect("activate", gtk.main_quit)

        menu.show_all()
        menu.popup(None, None, None, btn, time) 

if __name__ == '__main__':
    tray = TrayIcon()
    gtk.main()

Hope above code helps.
