Tabs & Panels

Tabs

Top: Horizontal Tab header in the Topbar. Bottom: Vertical Tab header shows tab icons in the Properties Editor.

Tabs are used to control overlapping sections in the user interface. Contents of only one Tab is visible at a time. Tabs are listed in Tab header, which can be vertical or horizontal.

Switching/Cycling

Vertical tabs can be switched with Ctrl-Wheel from anywhere in the region, and horizontal tabs with mouse cursor over tab headings.

You can also cycle through tabs with Ctrl-Tab and Shift-Ctrl-Tab, or press down LMB and move mouse over tab header icons.

Panels

Panels in Properties editor.

A panel is highlighted in yellow and a sub-panel in red.

The smallest organizational unit in the user interface is a panel. Panel header is always visible, and it shows the title for the panel. Panels may also include sub-panels.

Collapsing and Expanding

A panel can either be expanded to show its contents, or collapsed to hide its contents. An expanded panel is indicated by a down-arrow (▼) in the panel header, while a collapsed panel is shown with a right-arrow (►).

  • A click with the LMB on the panel header expands or collapses it.

  • Pressing A expands/collapses the panel under the mouse pointer.

  • A Ctrl-LMB click on the header of a specific panel will collapse all other panels and make this the only expanded one.

  • Dragging with LMB over the headers will expand or collapse many at once.

Position

You can change the position of a panel within its region by clicking and dragging it with the LMB on the grip widget (::::) located in the Panel Header on the right side.

Pinning

Sometimes it is desirable to view panels from different tabs at the same time. This has been solved by making panels pinnable.

A pinned panel remains visible regardless of which tab has been selected. You can pin a panel by clicking on the pin icon in its header. Panels that do not have a pin icon can also be pinned by RMB and selecting Pin, alternatively you use Shift-LMB on the panel to also pin it.

Zoom

The zoom factor of a whole region with panels can be changed by Ctrl-MMB clicking and moving the mouse anywhere within that region or use the NumpadPlus and NumpadMinus to zoom in and out the contents. Pressing Home (Show All) will reset the zooming at the screen/panel focused by the mouse pointer.
