Python Tkinter，更改特定的行背景顏色？

Question

我已經能夠改變整個窗口，並通過該特定標籤的背景色，

master.configure(background = 'SteelBlue1') 
titlelabel = Tkinter.Label(master, text="my Title", fg = "blue4", bg = "gray80").grid(row=0, column = 1) 

有一個簡單的方法，使行灰度0，而不僅僅是標籤周圍的區域？由於

如果只有該行標題，您可以使用columspan，這樣對所有的列標題跨度和擴大水平標籤：

import Tkinter 

master = Tkinter.Tk() 

master.configure(background='SteelBlue1') 
master.columnconfigure(0, weight=1) # make the column 1 expand when the window is resized 
nb_of_columns = 2 # to be replaced by the relevant number 
titlelabel = Tkinter.Label(master, text="my Title", fg="blue4", bg ="gray80") 
titlelabel.grid(row=0, column=0, sticky='ew', columnspan=nb_of_columns) # sticky='ew' expands the label horizontally 

master.geometry('200x200') 
master.mainloop() 

否則，解決的辦法是遵循scotty3785意見和使用一個框架：

import Tkinter 

master = Tkinter.Tk() 

master.configure(background='SteelBlue1') 
master.columnconfigure(1, weight=1) 

nb_of_columns = 2 # to be replaced by the relevant number 
titleframe = Tkinter.Frame(master, bg ="gray80") 
titleframe.grid(row=0, column=0, columnspan=nb_of_columns, sticky='ew') 
titlelabel = Tkinter.Label(titleframe, text="my Title", fg="blue4", bg ="gray80") 
titlelabel.grid(row=0, column=1) 
# other widgets on the same row: 
Tkinter.Button(titleframe, text='Ok').grid(row=0, column=2) 

master.geometry('200x200') 
master.mainloop()
