Hi @ all!

I don’t want the user to maximize the TkRoot - window with the button on  
the right side of the window! How can I disable this one? Or how can I  
make the size of my window fixed?

Thanks in advance! ALEX

I think this is the code example u are looking for

require “tk”  
p Tk.root.protocol “WM\_DELETE\_WINDOW”, proc {puts “foo”}  
p Tk.root.protocol “WM\_TAKE\_FOCUS”, proc {puts “bar”}  
p Tk.root.protocol “WM\_DELETE\_WINDOW”  
p Tk.root.protocol

p Tk.root.protocol “WM\_DELETE\_WINDOW”, “”  
p Tk.root.protocol “WM\_DELETE\_WINDOW”  
p Tk.root.protocol  
Tk.mainloop

Please try Tk.root.resizable(false, false) or  
Tk.root.maxsize(x, y) or both of them.

Thank you very much, Tk.root.resizable(false, false) works!!!
