What are you trying to achieve by "drawing over" widgets?
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.
Sorry for being unclear.
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('<ButtonPress-3>', button_pressed)
widget.bind('<B3-Motion>', button_moved)
widget.bind('<Any-ButtonRelease-3>', 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()
