From: random joe on 11 Jun 2010 19:40 Hello all, Hi this i my first post here. I would like to create a tkinter toplevel window with a custom resize action based on a grid. From the Tk docs it say you can do this but for the life of me i cannot figure out how? In my app i wish for the main window to only resize in 20 pixel "jumps" (if you will). I have tried using the toplevel.grid() and setgrid option and no luck! ## here is the tk doc page about setGrid http://www.tcl.tk/man/tcl/TkLib/SetGrid.htm ## here is the Tkinter method from wm class def wm_grid(self, baseWidth=None, baseHeight=None, widthInc=None, heightInc=None): """Instruct the window manager that this widget shall only be resized on grid boundaries. WIDTHINC and HEIGHTINC are the width and height of a grid unit in pixels. BASEWIDTH and BASEHEIGHT are the number of grid units requested in Tk_GeometryRequest.""" return self._getints(self.tk.call( 'wm', 'grid', self._w, baseWidth, baseHeight, widthInc, heightInc)) grid = wm_grid ## Here is my code. from Tkinter import * class TopWin(Tk): def __init__(self): Tk.__init__(self)#, setgrid=1) #self.maxsize(width=50, height=50) #self.minsize(width=1, height=1) self.grid(10, 10, 20, 20) topwin = TopWin() topwin.mainloop() Please help. I am going nuts trying to make this work for three hours already :(

Seems tk just passes the options to the window manager, so if the wm decides to ignore them, you're stuck, I'd say. By the way, you should use more drastic values for your tests. I tried with self.grid(10, 10, 20, 20) and I hardly saw that it worked. Using self.grid(0, 0, 100, 100) made it obvious. HTH - Eric - |
