python3.3 tkinter ttk'填充'

Question

The padding option for widgets can be set like this:

frm = ttk.Frame(padding = "5 5 10 10")

I'd like to examine and change this during program execution, and have written this:

if frm['padding'] == "5 5 10 10":
    do something

The problem is, "5 5 10 10" is not returned! I get pixel object at 0x1d753f0, etc. As the memory location changes with every time the program runs, this is of no use to me. How can I get a usable response?

Answer 1

frm['padding'] returns a tuple of pixel objects. You can get each pixel object value via its string attribute:

for po in f['padding']: 
    print po.string
