You can implement tooltips for a
toolbar-button
exactly as for collections and so on as described in Tooltips for collections, elements and menu items. Supply
help-key
for the
toolbar-button
and a
help-callback
for the
interface
. For an example of this see
examples/capi/elements/toolbar.lisp
.
However, if your
toolbar-button
s are grouped in a
toolbar-component
it is simpler to supply the
:tooltips
initarg.
tooltips
should be a list containing a string giving the tooltip text of each button in the component. For an example of this see
examples/capi/applications/simple-symbol-browser.lisp
.
