Tkinter has three mechanisms for geometry management: place, pack, and grid.

The place manager uses absolute pixel coordinates.

The pack manager places widgets into one of 4 sides. New widgets are placed next to existing widgets.

The grid manager places widgets into a grid similar to a dynamically resizing spreadsheet.

Place

The most common keyword arguments for widget.place are as follows:

• x, the absolute x-coordinate of the widget
• y, the absolute y-coordinate of the widget
• height, the absolute height of the widget
• width, the absolute width of the widget

A code example using place:

class PlaceExample(Frame):
    def __init__(self,master):
        Frame.__init__(self,master)
        self.grid()
        top_text=Label(master,text="This is on top at the origin")
        #top_text.pack()
        top_text.place(x=0,y=0,height=50,width=200)
        bottom_right_text=Label(master,text="This is at position 200,400")
        #top_text.pack()
        bottom_right_text.place(x=200,y=400,height=50,width=200)
# Spawn Window
if __name__=="__main__":
    root=Tk()
    place_frame=PlaceExample(root)
    place_frame.mainloop()

Pack

widget.pack can take the following keyword arguments:

• expand, whether or not to fill space left by parent
• fill, whether to expand to fill all space (NONE (default), X, Y, or BOTH)
• side, the side to pack against (TOP (default), BOTTOM, LEFT, or RIGHT)

Grid

The most commonly used keyword arguments of widget.grid are as follows:

• row, the row of the widget (default smallest unoccupied)
