Returns the value of the on-set-focus event property of
dialog-item. The value of the on-set-focus property should be a
function object or a function name (a symbol naming a function). This
function is called when the focus moves to
dialog-item. This function should accept one
argument, the dialog-item. The value may be
nil if no function need be called. Because the focus
can change a lot if the user moves the cursor about, this function
should be simple and fast so as not to slow down the application. A
standard use is to change the cursor. See also on-kill-focus.
