One or more rectangles or squares. Options for border and solid or transparent fill also allow rectangular frames.
See also element type backColor.
In the unusual case that you draw multiple rectangles in the same element and they overlap and have transparency, (properties color, borderColor below), you need to set backColor = <cds>"opaque"<cds> for accurate display.
"Ends on its own" means ends automatically at that point. If an element can end on its own, you don't need to set end conditions for it in property end (unless you want it to maybe end earlier).
No—runs until any condition you set in property end.
You can vary or allow the subject to adjust the following properties of an object of this type when it's running. If you need to make other properties adjustable, you can edit the element type code—see Element Type Programming Manual.

Default: a square with sides 5 deg
A number that is side length for a square, or a vector [width height] for a rectangle (deg). Or you can use multiple rows for different sizes for different rectangles—see positions below.
Default: white
A 1×3 RGB vector with numbers between 0–1 setting fill color. You can also use a 1×4 RGBA vector to give the fill transparency, and set A = 0 for no fill. Or an n×3/4 matrix for different colors/transparencies for different rectangles—see positions below.
Default: borderWidth = no border
Default: borderColor = white
borderColor is a 1×3 RGB vector with numbers between 0–1 setting border color. You can also use a 1×4 RGBA vector to give the border transparency. Or an n×3/4 matrix for different border colors/transparencies for different rectangles.
Default: show one rectangle centered at element position
If you show multiple rectangles then for each of the other properties above you can set one value for all of them, or you can set different values for different rectangles using a vector or matrix (see property).
<cd>[]<cd> = show one rectangle centered at element position.
PsychBench uses record properties to record information during experiments. You can't set record properties but you can see them in experiment results using input property report.
