Python GUI tkinter库 自学22

1、一个经典的面向程序写法模块

from tkinter import *
from tkinter.colorchooser import *


class Appication(Frame):
    """
    一个经典的 GUI 类的写法
    """
    def __init__(self, master=None):
        super().__init__(master)
        self.master = master
        self.pack()
        self.CreateWidget()

    def CreateWidget(self):
        pass


if __name__ == "__main__":
    window = Tk()
    window.geometry("200x200+200+200")

    app = Appication(master=window)

    window.mainloop()

2、菜单模块

# class Appication(Frame):
#     """
#     一个经典的 GUI 类的写法
#     """
    def CreateWidget(self):
        # 创建主菜单栏
        self.mainmenu = Menu(window)

        # 创建子菜单
        self.menuFile = Menu(self.mainmenu)
        self.menuEdit = Menu(self.mainmenu)
        self.menuHelp = Menu(self.mainmenu)

        # 将子菜单加入到主菜单
        self.mainmenu.add_cascade(label="文件(F)", menu=self.menuFile)
        self.mainmenu.add_cascade(label="编辑(E)", menu=self.menuEdit)
        self.mainmenu.add_cascade(label="帮助(H)", menu=self.menuHelp)

        # 添加菜单项
        self.menuFile.add_command(label="新建", accelerator="ctrl + n", command=self.test)
        self.menuFile.add_command(label="打开", accelerator="ctrl + o", command=self.test)
        self.menuFile.add_command(label="保存", accelerator="ctrl + s", command=self.test)
        self.menuFile.add_separator()
        # 添加分割线
        self.menuFile.add_command(label="退出", accelerator="ctrl + q", command=self.test)

        # 将主菜单栏加到根窗口
        window["menu"] = self.mainmenu

        # 文本编辑区
        self.textpad = Text(window, width=50, height=30)
        self.textpad.pack()

        # 创建上下菜单
        self.contextMenu = Menu(window)
        self.contextMenu.add_command(label="背景颜色", command=self.test)

        # 为右键绑定上下菜单
        window.bind("", self.createContextMenu)

3、菜单模块引用的函数

# class Appication(Frame):
#     """
#     一个经典的 GUI 类的写法
#     """
    def createContextMenu(self, event):
        # 菜单在鼠标右键单击的坐标出显示
        self.contextMenu.post(event.x_root, event.y_root)

    def test(self):
        pass

4、源代码

from tkinter import *
from tkinter.colorchooser import *


class Appication(Frame):
    """
    一个经典的 GUI 类的写法
    """
    def __init__(self, master=None):
        super().__init__(master)
        self.master = master
        self.pack()
        self.CreateWidget()

    def CreateWidget(self):
        # 创建主菜单栏
        self.mainmenu = Menu(window)

        # 创建子菜单
        self.menuFile = Menu(self.mainmenu)
        self.menuEdit = Menu(self.mainmenu)
        self.menuHelp = Menu(self.mainmenu)

        # 将子菜单加入到主菜单
        self.mainmenu.add_cascade(label="文件(F)", menu=self.menuFile)
        self.mainmenu.add_cascade(label="编辑(E)", menu=self.menuEdit)
        self.mainmenu.add_cascade(label="帮助(H)", menu=self.menuHelp)

        # 添加菜单项
        self.menuFile.add_command(label="新建", accelerator="ctrl + n", command=self.test)
        self.menuFile.add_command(label="打开", accelerator="ctrl + o", command=self.test)
        self.menuFile.add_command(label="保存", accelerator="ctrl + s", command=self.test)
        self.menuFile.add_separator()
        # 添加分割线
        self.menuFile.add_command(label="退出", accelerator="ctrl + q", command=self.test)

        # 将主菜单栏加到根窗口
        window["menu"] = self.mainmenu

        # 文本编辑区
        self.textpad = Text(window, width=50, height=30)
        self.textpad.pack()

        # 创建上下菜单
        self.contextMenu = Menu(window)
        self.contextMenu.add_command(label="背景颜色", command=self.test)

        # 为右键绑定上下菜单
        window.bind("", self.createContextMenu)

    def createContextMenu(self, event):
        # 菜单在鼠标右键单击的坐标出显示
        self.contextMenu.post(event.x_root, event.y_root)

    def test(self):
        pass


if __name__ == "__main__":
    window = Tk()
    window.geometry("200x200+200+200")

    app = Appication(master=window)

    window.mainloop()
