如何同时拖放多个小部件我可以拖动标签但想同时拖动它们

Question

from tkinter import *

def vp_start_gui():
    root = Tk()
    top = Toplevel1 (root)

root.mainloop()

class Toplevel1:
    def __init__(self, top=None):

        top.geometry("300x300")

I use all of your funtions they work great the way you had them but if I put it a class is doesent work well

if I select individually it jumps about half a screen def select_and_drag(widgets_list): """Drags all the widgets together in the given list with mouse point.

            Args:
            widgets_list (list, tuple): Takes list of widgets 
                to be moved together."""

            def set_drag(evt):
                """Set iniitial points."""
                for w in widgets_list:
                    w._drag_x = evt.x 
                    w._drag_y = evt.y

            def on_drag(evt):
                """Drags with mouse."""
                for w in widgets_list:
                    x = w.winfo_x() - w._drag_x + evt.x
                    y = w.winfo_y() - w._drag_y + evt.y
                    w.place(x=x, y=y)

            for wid in widgets_list:
                wid.bind("<Button-1>", set_drag, '+')
                wid.bind("<B1-Motion>", on_drag, '+')

        self.Label1_3 = Label(top)
        self.Label1_3.place(relx=0.687, rely=0.183, height=36, width=124)
        self.Label1_3.configure(text='''Height''', bg="brown")

        self.Label1 = Label(top, text="try")
        self.Label1.pack()

        select_and_drag((self.Label1_3, self.Label1))
        select_and_drag((self.Label1,))

    if __name__ == '__main__':
    vp_start_gui()

Yes, it is possible and you are almost there with your code. I just modified and improved your drag functionality, I made one function select_and_drag(widget_list) which takes a list of widgets and makes a set of them together, which means moving one widget will make all the widgets in that set move along.

Here is the function.

def select_and_drag(widgets_list):
    """Drags all the widgets together 
    in the given list with mouse point.

    Args:
        widgets_list (list, tuple): Takes list of widgets 
                to be moved together."""

    def set_drag(evt):
        """Set iniitial points."""
        for w in widgets_list:
            w._drag_x = evt.x 
            w._drag_y = evt.y

    def on_drag(evt):
        """Drags with mouse."""
        for w in widgets_list:
            x = w.winfo_x() - w._drag_x + evt.x
            y = w.winfo_y() - w._drag_y + evt.y
            w.place(x=x, y=y)

    for wid in widgets_list:
        wid.bind("<Button-1>", set_drag, '+')
        wid.bind("<B1-Motion>", on_drag, '+')

How to use it?

More than one set can be created with different widgets from this function. You can get an idea from this example below, move each SET and see for yourself.

from tkinter import *

root  = Tk()
root.geometry("600x350")

# SET 1
lbl1 = Label(root, text='SET1', fg='red')
lbl1.pack()
lbl2 = Label(root, text='SET1', fg='red')
lbl2.pack()

# Common for SET1 and SET3
lbl3 = Label(root, text='SET1 and SET3', 
             bg='pink', fg='red') 
lbl3.pack()

# SET2
lbl4 = Label(root, text='SET2', bg='lightblue')
lbl4.pack()
lbl5 = Label(root, text='SET2', bg='lightblue')
lbl5.pack()

# SET2
lbl6 = Label(root, text='SET3', bg='pink')
lbl6.pack()

# Make SETS.
select_and_drag((lbl1, lbl2, lbl3))
select_and_drag((lbl4, lbl5))
select_and_drag((lbl3, lbl6))

root.mainloop()
