Package

Signature

accepts-focus-p element => result

Arguments

element

A CAPI element.

Values

result

A boolean.

Description

Determines if the element element accepts the focus for user input, and controls tabstops.

The method on element uses the value of the accepts-focus-p slot, but methods on some subclasses override this.

accepts-focus-p also influences whether a pane is a tabstop. On Microsoft Windows a pane acts as a tabstop if and only if the function accepts-focus-p returns true and the element accepts-focus-p initarg value is :force. On Motif and Cocoa, a pane acts as a tabstop if and only if the function accepts-focus-p returns true.
