### Changing the Sizes of the Panes

If you want to change the sizes of the existing panes or change their maximum/minimum size constraints, you can use the `paneconfigure` method. For example, the following code changes the size of `pane2` to 100 pixels and adjusts its minimum size constraint to no less than 10 pixels:

> `.p paneconfigure pane2 -size 100 -min 10`

Notice that after you call the `paneconfigure` method, the PanedWindow may jitter and that may annoy the user. Therefore, use this method only when it is necessary.
