I am trying to prevent a user from resizing a frame beyond its
"natural" size as given by winfo_reqwidth and winfo_reqheight, without
any success. Can anyone make any suggestions, based on my code below?
Thanks!
from Tkinter import *
class Table(Frame):
def __init__(self, master,
rows=['row 1'], cols=['col 1'],
row_labels=True,
col_labels=True,
row_buttons=True,
col_buttons=True):
Frame.__init__(self, master)
self.rows = rows
self.cols = cols
self.row_labels = row_labels
self.col_labels = col_labels
self.row_buttons = row_buttons
self.col_buttons = col_buttons
self.col_width = 6
self.draw()
self.bind('<Configure>', self.changed)
def changed(self, ev):
w, h = self.winfo_reqwidth(), self.winfo_reqheight()
cfg = {}
if ev.height > h:
cfg['height'] = h
if ev.width > w:
cfg['width'] = w
if cfg:
self.config(**cfg) ######## this has no effect ########
I'm not sure I follow your code but this method is bound to the
<Configure> event *but* needs to return the string "break" so that it
does not pass that event on to the default event handler.
def changed(self, ev):
w, h = self.winfo_reqwidth(), self.winfo_reqheight()
cfg = {}
if ev.height > h:
cfg['height'] = h
if ev.width > w:
cfg['width'] = w
if cfg:
self.config(**cfg) ######## this has no effect ########
return "break"
This may do what you want.....
Cheers
