Arguments: window
This generic function is called whenever the user left-clicks the
"question-mark button" on the frame of a frame-window
that has the help-button property.
window is the frame-window that has the
help-button that was clicked. Applications may override the default
method in order to tell the user what to do next in some custom way.
The behavior of the help-button is hard-wired to wait for the user to left-click a control or child window in that window, and to then call context-sensitive-help with that control or child window (unless the user cancels by pressing the ESCAPE key or clicking elsewhere). help-button-pressed is therefore useful only for telling the user to click on a control or child window in that window for some reason.
The default method calls window-message on
window with the string "Left-click a control in
the same window for help on that control." Due to the general
functionality of window-message, this string will
appear in the window's status-bar
or common-status-bar
if the window has
one, or else will appear in an ancestor window's status-bar
or common-status-bar
, if any.
