Expand description

The shape of the system cursor a widget can request for a given sub-region (milestone 205). The shell translates it to the window’s cursor; widgets stay independent of the windowing layer.

Variants§

Default

The default arrow.

Pointer

A hand (a clickable element).

Text

A vertical bar (a text entry area).

None

No cursor at all: it is hidden while over the region (milestone 583).

Forbidden

Something that cannot be done here — a disabled control, a drop that is refused.

Wait

The application is busy and takes no input.

Progress

The application is busy, and still takes input.

Help

Help is available.

Precise

A precise pick: a crosshair.

Move

Something that can be moved.

Grab

Something that can be grabbed and dragged.

Grabbing

Something being dragged.

ResizeColumn

A boundary that moves left and right: a column’s edge.

ResizeRow

A boundary that moves up and down: a row’s edge.

ZoomIn

Zoom in.

ZoomOut

Zoom out.

ContextMenu

A context menu is available.
