我想个性化菜单栏。例如,我想删除tk.Menu小部件周围出现的边框(使用add_command()方法)
那是我的代码(我正在使用Windows 10)
import tkinter as tk from tkinter import ttk dark_grey = "#212121" dark_blue="#102A43" blue_1="#243B53" root = tk.Tk() root.state('zoomed') container = tk.Frame(root, bg = dark_grey) container.grid_rowconfigure(0, weight = 0) container.grid_columnconfigure(0, weight = 1) menu_frame = tk.Frame(container, bg = dark_blue) menu1 = tk.Menubutton(menu_frame, text = "Menu1", bg = dark_blue, fg = "white", activebackground = blue_1, activeforeground = "white") menu1.grid(row = 0, column = 0) submenu1 = tk.Menu(menu1, tearoff = 0, bg = dark_blue, activebackground= blue_1, fg = "white",borderwidth = 0, activeborderwidth= 0) submenu1.add_command(label = "Option 1.1") submenu1.add_command(label = "Option 1.2") menu1.configure(menu = submenu1) menu_frame.grid(row = 0, column = 0, sticky = "ew") container.pack(fill = tk.BOTH, expand = "True") root.mainloop()
我的想法是在不使用tk.Menu和tk.MenuButton的情况下创建菜单。我想将<Enter>事件“绑定”到标签,以便在标签下创建某种下拉菜单。可能吗?
<Enter>
问题 :自定义菜单栏是否不使用小部件tk.Menu?
tk.Menu
本示例使用atk.Toplevel作为弹出窗口,并显示添加的tk.Menubutton。 子 菜单 遵循定义的“ 顶部 样式 ”tk.Menubutton。
tk.Toplevel
tk.Menubutton
待办事项 : 如果在外部或其他 顶部 单击,请关闭弹出窗口Menubutton。 除其他以外扩展 tk.Menubutton 键盘支持
待办事项 :
Menubutton
import tkinter as tk class Menu: def __init__(self, parent, **kwargs): self._popup = None self._menubutton = [] self.parent = parent self.parent.bind('<Button-1>', self.on_popup) def on_popup(self, event): w = event.widget x, y, height = self.parent.winfo_rootx(), self.parent.winfo_rooty(), self.parent.winfo_height() self._popup = tk.Toplevel(self.parent.master, bg=self.parent.cget('bg')) self._popup.overrideredirect(True) self._popup.geometry('+{}+{}'.format(x, y + height)) for kwargs in self._menubutton: self._add_command(**kwargs) def add_command(self, **kwargs): self._menubutton.append(kwargs) def _add_command(self, **kwargs): command = kwargs.pop('command', None) menu = self.parent mb = tk.Menubutton(self._popup, text=kwargs['label'], bg=menu.cget('bg'), fg=menu.cget('fg'), activebackground=menu.cget('activebackground'), activeforeground=menu.cget('activeforeground'), borderwidth=0, ) mb._command = command mb.bind('<Button-1>', self._on_command) mb.grid() def _on_command(self, event): w = event.widget print('_on_command("{}")'.format(w.cget('text'))) self._popup.destroy() if w._command is not None: w._command()
用法 :
class App(tk.Tk): def __init__(self): super().__init__() self.geometry("200x200") style = {'bg': "#102A43", 'fg': "white", 'activebackground': "#243B53", 'activeforeground': "white", 'borderwidth': 0} menu1 = tk.Menubutton(self, text="Menu1", **style) submenu1 = Menu(menu1) submenu1.add_command(label="Option 1.1") submenu1.add_command(label="Option 1.2") menu1.grid(row=0, column=0) menu2 = tk.Menubutton(self, text="Menu2", **style) submenu2 = Menu(menu2) submenu2.add_command(label="Option 2.1") submenu2.add_command(label="Option 2.2") menu2.grid(row=0, column=2) if __name__ == "__main__": App().mainloop()
