Re: Tkinter custom drawing
Thank you this is nice code. I never thought of using the move_pending method.. Still it doesn't answer my question (which I ensure is very unclear). But do not worry, I found some way to get throught my dilemma and I can live easily with it. Thanks for your help. -- http://mail.python.org/mailman/listinfo/python-list

You may want to look into the place() method. The python mega widgets
(PMW) has a PanedWidget that implements this smoothly. You may want to
emulate that approach:
#! /usr/bin/env python
from Tkinter import *
def button_pressed(e):
moved = e.widget
moved.move_pending = True
moved['cursor'] = 'hand1'
moved.press_x = e.x
moved.press_y = e.y
def button_moved(e):
moved = e.widget
if moved.move_pending:
moved.after_idle(lambda e=e: _button_moved(e))
moved.move_pending = False
def _button_moved(e):
moved = e.widget
delta_x = e.x - moved.press_x
delta_y = e.y - moved.press_y
size, wx, wy = moved.winfo_geometry().split('+')
new_x = int(wx) + delta_x
new_y = int(wy) + delta_y
moved.place(x=new_x, y=new_y)
moved.update_idletasks()
moved.move_pending = True
def button_up(e):
e.widget['cursor'] = ''
def register(widget):
widget.bind('', button_pressed)
widget.bind('', button_moved)
widget.bind('', button_up)
widget.update_idletasks()
def test():
tk = Tk()
b = Button(tk, text='Button')
b.pack()
c = Button(tk, text='Another Button')
c.pack()
x = Label(tk, text='Drag Me', relief=RIDGE, border=1)
register(x)
x.pack()
tk.geometry('200x200')
tk.mainloop()
if __name__ == "__main__":
test()

Want I want to do is a sort of GUI builder for Tkinter. I already finished a rough version, but for now I'm making a lighter version of this project. So, my intent, is to create a widget under the widget. While dragging the mouse, I want to see this rectangle that defines the boundaries of the new widget I'm creating.
