Why is the widget not at the center of the window although it is in the center of the grid?

I have created a label, which I placed in the center row and center column of a grid:

label .mytext -text "Hello!"

grid x    x    x -in .
grid x .mytext x
grid x    x    x -in .

grid rowconfigure . 0 -weight 1
grid rowconfigure . 1 -weight 1
grid rowconfigure . 2 -weight 1

grid columnconfigure . 0 -weight 1
grid columnconfigure . 1 -weight 1
grid columnconfigure . 2 -weight 1

wm geometry . 300x200

However, the label does not appear exactly at the center of the window; it is above the center:

Why is the label not exactly at the center of the window, even though I have placed it in the center of the grid?

Your grid x x x -in . command effectively does nothing. The grid x .mytext x command puts the label in the first empty row, which is row 0. You can verify this with grid info .mytext.

To achieve what you seem to be trying, you can do:

label .mytext -text "Hello!"
grid .mytext -row 1 -column 1
grid rowconfigure . {0 1 2} -weight 1
grid columnconfigure . {0 1 2} -weight 1
wm geometry . 300x200

When doing it that way, the label does end up centered.
