ttk

问题 With this code fragment, I would expect the label to have a background color red. def createWidgets(self): style = ttk.Style() style.configure("Red.TLabel", foreground="green", background="red") self.label1 = ttk.Label(textvariable=self.numberArray[0][0],style="Red.TLabel") self.label1.pack() I get the green foreground color but I can't change the background color. This is on OS X. I'm using ActiveState's tcl and python. The same problem occurs with Python 3.2 and 2.7 回答1: You'll sometimes

问题 I started making a GUI with Tkinter and I added the module tkMessageBox as well. But recently I discovered that importing the module ttk gives more 'up-to-date' results: buttons and texts boxes appear with the actual style of the current OS.

But unfortunately, I can't find a way to use this ttk themed widgets on the common Dialog Boxes (the ones which I imported from

问题 The size of Tkinter windows can be controlled via the following methods: .minsize() .maxsize() .resizable() Are there equivalent ways to control the size of Tkinter or ttk Frames? @Bryan: I changed your frame1.pack code to the following: frame1.pack(fill='both', expand=True) frame1.bind( '<Configure>', maxsize ) And I added this event handler: # attempt to prevent frame from growing past a certain size def maxsize( event=None ): print frame1.winfo_width() if frame1.winfo_width() > 200: print
