Python–在 GTK+ 3 中创建窗口按钮
原文:https://www . geesforgeks . org/python-create-window-button-in-GTK-3/
GTK+ 3 是一个免费的开源跨平台小部件工具包，用于创建图形用户界面(GUI)。它是根据 GNU 小通用公共许可证的条款许可的。与 Qt 一起，它是 Wayland 和 X11 窗口系统最受欢迎的工具包之一。让我们看看如何使用 GTK+ 3 创建窗口和按钮。 遵循 以下步骤:
- 导入 GTK+ 3 模块
- 创建主窗口。
- 创建按钮。
我们必须导入 Gtk 模块才能访问 GTK+的类和函数。 注意:在像 Pycharm 这样的 ide 中，为了使用 GTK+ 3，我们可以安装一个名为 PyGObject 的包。 代码#1: 创建一个 200 x 200 像素的空窗口。
Python 3
import gi
# Since a system can have multiple versions
# of GTK + installed, we want to make
# sure that we are importing GTK + 3.
gi.require_version("Gtk", "3.0")
from gi.repository import Gtk
# Creates an empty window.
window = Gtk.Window()
# Connecting to the window’s delete event
# to ensure that the application is terminated
# whenever we click close button
window.connect("destroy", Gtk.main_quit)
# Display the window.
window.show_all()
Gtk.main()
输出:
代码#2: 创建按钮
Python 3
import gi
gi.require_version("Gtk", "3.0")
from gi.repository import Gtk
# Define our own newWindow class.
class newWindow(Gtk.Window):
def __init__(self):
# Call the constructor of the super class.
# Set the value of the property title to Geeks for Geeks.
Gtk.Window.__init__(self, title ="Geeks for Geeks")
# Create a button widget, connect to its clicked signal
# and add it as child to the top-level window.
self.button = Gtk.Button(label ="Click Here")
self.button.connect("clicked", self.on_button_clicked)
self.add(self.button)
# When we click on the button this method
# will be called
def on_button_clicked(self, widget):
print("Geeks for Geeks")
win = newWindow()
win.connect("destroy", Gtk.main_quit)
win.show_all()
Gtk.main()
输出:
