frame

This is the code that's giving me trouble. f = Frame(root, width=1000, bg="blue") f.pack(fill=X, expand=True) l = Label(f, text="hi", width=10, bg="red", fg="white") l.pack() If I comment out the lines with the Label, the Frame displays with the right width. However, adding the Label seems to shrink the Frame down to the Label's size. Is there a way to prevent that from happening? By default, tk frames shrink or grow to fit their contents , which is what you want 99% of the time. The term that describes this feature is "geometry propagation". There is a command to turn geometry propagation on

I have a pretty basic setup with a UINavigationController inside a UITabBarController. I'm wanting to programmatically layout the view of the rootViewController of that navcontroller, but when I look at self.view.frame inside viewDidLoad, I get this (in landscape , for example): 1. view frame: {{20, 0}, {748, 1024}} // looks like an odd portrait mode Then I autorotate to Portrait, and I get this: 2. view frame: {{0, 0}, {768, 911}} Then when I go back to Landscape, the frame is now this: 3. view frame: {{0, 0}, {1024, 655}} And further autorotation events will flip-flop between frame values #2
