windowtoolbar

A window toolbar, or toolbar, is a graphical user interface element that provides quick access to a set of actions within a window. It is typically a horizontal strip located near the top of the window’s client area, just under the title bar, but in many applications it can be docked to the sides, auto-hidden, or shown as a collapsible panel.

A toolbar contains controls such as buttons, icons, text labels, separators, and sometimes drop-down menus or split buttons. The items usually reflect commands that are frequently used, and they can be bound to application actions so their enabled state reflects context. Tooltips and keyboard shortcuts improve discoverability and accessibility. In many frameworks toolbars can be customized by the user or by the application, enabling addition, removal, or rearrangement of items.

Across major platforms, toolbars are implemented with platform-specific controls: Windows uses the ToolBar control (Win32) and newer ToolStrip in Windows Forms and ToolBar in WPF; macOS uses NSToolbar; Qt provides QToolBar; GTK offers GtkToolbar.

Design considerations include:

- Placement and visibility: maintain balance with other UI elements; allow auto-hide or docking.

- Iconography and labeling: use clear icons; include text when space allows; ensure localization.

- Accessibility: provide keyboard access and screen reader support; maintain logical focus order.

- Customization and persistence: support user-defined layouts and saving them.

- Responsiveness: adapt to window resizing and high-DPI scaling.

Although some modern interfaces favor ribbons or contextual action bars, traditional window toolbars remain common in many desktop applications for providing rapid access to frequently used commands.
