draw-focus

Arguments: picture-button-or-multi-picture-button

Returns whether the focus rectangle is drawn in a multi-picture-button or picture-button when it has the keyboard focus.

The value can be t or nil. If nil, no focus rectangle is drawn, and hitting the SPACE key will not press a button since no particular button has the keyboard focus. You click on a button and it appears pressed in as usual, but no focus rectangle gets drawn.

If the value is t, when the argument control has the keyboard focus, draws a focus rectangle around the particular button that has the focus within the control. The arrow keys will move the focus to other buttons, scrolling as needed. You click on a button and a focus rectangle appears over the clicked button.

draw-focus is a property of the multi-picture-button and picture-button classes.
