glade画的gtk界面python里能直接调用

linux下假如没有安装相应库就自己命令装一下

sudo apt install python3-gi python3-gi-cairo gir1.2-gtk-3.0

来一段代码验证下

import gi
gi.require_version("Gtk", "3.0")
from gi.repository import Gtk

window = Gtk.Window(title="Test Window")
window.show()
window.connect("destroy", Gtk.main_quit)
Gtk.main()

能弹出窗口说明环境没问题，再来一段代码

import gi
gi.require_version("Gtk", "3.0")
from gi.repository import Gtk

class SimpleGUI:
    def __init__(self):
        # 创建一个窗口
        self.window = Gtk.Window(title="python GTK+ Example")
        self.window.set_default_size(600,300)
        self.window.connect("delete_event", Gtk.main_quit)

        # 创建一个标签
        self.label = Gtk.Label(label="Welcome to PyGtk!")

        # 创建一个按钮
        self.button = Gtk.Button(label="Click Me!")
        self.button.connect("clicked", self.on_button_clicked)
        # 创建退出按钮
        self.btnExit = Gtk.Button(label="退出")
        self.btnExit.connect("clicked", self.on_btnExit_clicked)
        # 创建一个垂直布局
        self.vbox = Gtk.VBox()
        self.vbox.pack_start(self.label, True, True, 0)
        self.vbox.pack_start(self.button, True, True, 0)
        self.vbox.pack_start(self.btnExit, True, True, 0)
        # 设置窗口的内容
        self.window.add(self.vbox)
        self.window.show_all()

    def on_button_clicked(self, widget):
        self.label.set_text("Button Clicked!")
    def on_btnExit_clicked(self, widget):
        self.window.close()    

if __name__ == "__main__":
    gui = SimpleGUI()
    Gtk.main()

说明python和gtk配合很好，下面就用glade画一个界面 test.glade

然后到python里调用 pygtkmain.py

import gi
gi.require_version("Gtk", "3.0")
from gi.repository import Gtk

class pygtkmain():
    """This is the pygtkmain application"""
    def __init__(self):
        self.builder = Gtk.Builder()
        self.builder.add_from_file("test.glade")
        self.window = self.builder.get_object("form1")
        self.window.set_default_size(600,480)
        self.window.set_position(1)
        self.window.show()
        self.window.connect("destroy", Gtk.main_quit)
        self.text1 = self.builder.get_object("text1")
        self.label1 = self.builder.get_object("label1")
        self.btnTest = self.builder.get_object("btnTest")
        self.btnTest.connect("clicked", self.ontest)
        self.btnExit = self.builder.get_object("btnExit")
        self.btnExit.connect("clicked", self.onexit)
    def ontest(self, event=None):
        self.label1.set_text(self.text1.get_text())
    def onexit(self, event=None):
        self.window.close()

if __name__ == "__main__":
    winf = pygtkmain()
    Gtk.main()

运行顺利，以后python整带界面的就可以照这个思路整了。
