Tkinter: Mouse drag a window without borders, eg. overridedirect(1)

by

Yes, Tkinter exposes enough functionality to do this, and no, there are no easier/higher-level ways to achive what you want to do. You pretty much have the right idea.

Here’s one example, though it’s not the only way:

import tkinter as tk

class App(tk.Tk):
    def __init__(self):
        tk.Tk.__init__(self)
        self.floater = FloatingWindow(self)

class FloatingWindow(tk.Toplevel):
    def __init__(self, *args, **kwargs):
        tk.Toplevel.__init__(self, *args, **kwargs)
        self.overrideredirect(True)

        self.label = tk.Label(self, text="Click on the grip to move")
        self.grip = tk.Label(self, bitmap="gray25")
        self.grip.pack(side="left", fill="y")
        self.label.pack(side="right", fill="both", expand=True)

        self.grip.bind("<ButtonPress-1>", self.start_move)
        self.grip.bind("<ButtonRelease-1>", self.stop_move)
        self.grip.bind("<B1-Motion>", self.do_move)

    def start_move(self, event):
        self.x = event.x
        self.y = event.y

    def stop_move(self, event):
        self.x = None
        self.y = None

    def do_move(self, event):
        deltax = event.x - self.x
        deltay = event.y - self.y
        x = self.winfo_x() + deltax
        y = self.winfo_y() + deltay
        self.geometry(f"+{x}+{y}")

app=App()
app.mainloop()
