Sizegrip

Sizegrip is a small resize handle that indicates a window (or pane) can be resized.

It wraps bs.Sizegrip and is typically placed in the bottom-right corner of a resizable window, status bar, or footer.

Quick start

import bootstack as bs

app = bs.App()

content = bs.Frame(app, padding=20)
content.pack(fill="both", expand=True)

status = bs.Frame(app, padding=(8, 4))
status.pack(fill="x", side="bottom")

grip = bs.Sizegrip(status)
grip.pack(side="right")

app.mainloop()

When to use

Use Sizegrip when:

  • your UI includes a status bar/footer and you want an explicit resize affordance

  • your users expect classic desktop window cues

  • you want to provide a visual affordance for resizing

  • you want to match platform expectations in desktop apps

Consider a different control when:

  • your UI already makes resizing obvious (or resizing is disabled)

Appearance

On many platforms, users can resize windows by dragging the window border even without a sizegrip, so this widget is mainly a UX hint.

Design System

Examples & patterns

Sizegrip typically doesn't require additional configuration. Layout is controlled by geometry manager options such as side=, anchor=, padx=, and pady=.

Behavior

  • The sizegrip is not focusable and is not intended for keyboard interaction.

  • Dragging the grip resizes the toplevel window in standard ttk implementations.

Additional resources

  • Frame -- common container for status bars/footers

  • PanedWindow -- resizable split regions
