When a Python GUI application is designed with Tkinter, widgets (including buttons) require programming so that the underlying application logic can respond to mouse clicks and other actions. Additionally, in order for them to work as intended, widgets need to be positioned intuitively for the user.
Tkinter has three built-in layout managers that use geometric methods to position buttons in an application frame: pack, grid, and place.
- The pack manager organizes widgets in horizontal and vertical boxes that are limited to left, right, top, bottom positions offset from each other.
- The grid manager locates widgets in a two dimensional grid using row and column relative coordinates.
- The place manager places widgets in a two dimensional grid using x and y absolute coordinates.
How to Position Buttons With Pack
Pack() has three options you can use: side, fill, expand.
- The side option aligns buttons horizontally.
- The fill option aligns buttons vertically.
- The expand option takes up the full height of the frame.
How to Position Buttons With Grid
Grid() is used to position buttons based on row and column coordinates on a grid in a frame similar to a spreadsheet.
- The row option aligns button horizontally
- The column option alights button vertically
How to Position Buttons With Place
Place() is used to position buttons based on x,y coordinates in a frame.
- The x variable aligns button horizontally
- The y variable aligns button vertically
If you want to take advantage of the latest version of Tkinter, you’ll need to install a version of Python that supports Tcl/Tk 8.5 or greater. This will provide you with the Ttk (Tile extension integrated into Tk), which is required in order to run the current Tk widget set.
