為多種顏色的Tkinter按鈕着色

Question

我試圖在Tkinter的一個按鈕上放置多種顏色。 這就是我想出的：

from Tkinter import *
master = Tk()
buttons = {}

def press(clicked):
    print clicked
    return
for i in range(1,7):
    button_name = 'button '+str(i)
    buttons[i] = Button(master, text=button_name, command=lambda method=button_name:press(method))
    buttons[i].grid(row=0, column=i-1, padx=15)
    buttons[i].update()

    tot_x = buttons[i].winfo_width()
    tot_y = buttons[i].winfo_height()

    redframe = Frame(buttons[i], width=tot_x/6, background='red')
    blueframe = Frame(buttons[i], width=tot_x/6*5, background='blue')

    redframe.place(x=0, y=0, relheight=1)
    blueframe.place(relx=1./6, y=0, relheight=1)

master.mainloop()

問題在於它使按鈕幾乎不可點擊，因為框架會以某種方式干擾按鈕的“可點擊性”。 當光標放在它們的位置時，彩色框架也會突然消失。

有沒有辦法讓這些框架留在按鈕上並使它們不能停止點擊？

Answer 1

可以說，最簡單的方法可能是使用您想要的顏色創建圖像，然后使用按鈕中的圖像和文本。

Answer 2

雖然我認為Bryan的答案更簡單並且完全解決了問題，但您可以解決綁定的“可點擊性”問題（我沒有遇到第二個問題，所以我的答案沒有解決它）。

我們的想法是在框架上綁定鼠標點擊以觸發按鈕上的單擊並恢復通常的按鈕行為。 在下面的示例中，我綁定了<ButtonPress-1>和<ButtonRelease-1>以查看按鈕緩解效果。 我還綁定了<Enter>和<Leave>以在鼠標懸停時實現按鈕顏色更改。

from Tkinter import *
master = Tk()
buttons = {}

def press(clicked):
    print clicked

def frame_enter(redframe, blueframe):
    redframe.configure(background='coral1')
    blueframe.configure(background='royalblue1')

def frame_leave(redframe, blueframe):
    redframe.configure(background='red')
    blueframe.configure(background='blue')

def on_press(event, button):
    button.event_generate('<ButtonPress-1>', x=event.x, y=event.y)

def on_release(event, button):
    button.event_generate('<ButtonRelease-1>', x=event.x, y=event.y)

for i in range(1,7):
    button_name = 'button '+str(i)
    buttons[i] = Button(master, text=button_name, command=lambda method=button_name:press(method))
    buttons[i].grid(row=0, column=i-1, padx=15)
    buttons[i].update()

    tot_x = buttons[i].winfo_width()
    tot_y = buttons[i].winfo_height()

    redframe = Frame(buttons[i], width=tot_x/6, background='red')
    blueframe = Frame(buttons[i], width=tot_x/6*5, background='blue')

    redframe.place(x=0, y=0, relheight=1)
    blueframe.place(relx=1./6, y=0, relheight=1)
    redframe.bind('<ButtonPress-1>', lambda e, b=buttons[i]: on_press(e, b)) 
    blueframe.bind('<ButtonPress-1>', lambda e, b=buttons[i]: on_press(e, b)) 
    redframe.bind('<ButtonRelease-1>', lambda e, b=buttons[i]: on_release(e, b)) 
    blueframe.bind('<ButtonRelease-1>', lambda e, b=buttons[i]: on_release(e, b)) 
    redframe.bind('<Enter>', lambda e, rf=redframe, bf=blueframe: frame_enter(rf, bf)) 
    blueframe.bind('<Enter>', lambda e, rf=redframe, bf=blueframe: frame_enter(rf, bf)) 
    redframe.bind('<Leave>', lambda e, rf=redframe, bf=blueframe: frame_leave(rf, bf)) 
    blueframe.bind('<Leave>', lambda e, rf=redframe, bf=blueframe: frame_leave(rf, bf)) 

master.mainloop()

編輯：不需要保持按鈕，可以用框架替換它們。 這樣，不需要使用place ，彩色框架可以只包裝在里面：

from Tkinter import *
master = Tk()
buttons = {}

def press(clicked):
    print clicked

def frame_enter(redframe, blueframe):
    redframe.configure(background='coral1')
    blueframe.configure(background='royalblue1')

def frame_leave(redframe, blueframe):
    redframe.configure(background='red')
    blueframe.configure(background='blue')

def on_press(event, widget):
    widget.configure(relief='sunken')  # mimic button's relief effect on click 

def on_release(event, widget, text):
    widget.configure(relief='raised')  # mimic button's relief effect on click 
    press(text)

for i in range(1,7):
    button_name = 'button '+ str(i)
    buttons[i] = Frame(master, relief='raised', width=78, height=24, bd=2)
    buttons[i].grid(row=0, column=i-1, padx=15)
    buttons[i].update_idletasks()

    tot_x = buttons[i].winfo_width()
    tot_y = buttons[i].winfo_height()

    redframe = Frame(buttons[i], width=tot_x/6, height=tot_y, background='red')
    blueframe = Frame(buttons[i], width=tot_x/6*5, height=tot_y, background='blue')

    redframe.pack(side='left')
    blueframe.pack(side='left')
    redframe.bind('<ButtonPress-1>', lambda e, b=buttons[i]: on_press(e, b)) 
    blueframe.bind('<ButtonPress-1>', lambda e, b=buttons[i]: on_press(e, b)) 
    redframe.bind('<ButtonRelease-1>', lambda e, b=buttons[i], t=button_name: on_release(e, b, t)) 
    blueframe.bind('<ButtonRelease-1>', lambda e, b=buttons[i], t=button_name: on_release(e, b, t)) 
    redframe.bind('<Enter>', lambda e, rf=redframe, bf=blueframe: frame_enter(rf, bf)) 
    blueframe.bind('<Enter>', lambda e, rf=redframe, bf=blueframe: frame_enter(rf, bf)) 
    redframe.bind('<Leave>', lambda e, rf=redframe, bf=blueframe: frame_leave(rf, bf)) 
    blueframe.bind('<Leave>', lambda e, rf=redframe, bf=blueframe: frame_leave(rf, bf))
