To implement tooltips in an
output-pane
, call
display-tooltip
via a
:motion
gesture in the pane's
input-model
. The tooltip text might depend on the cursor position or, in the case of a
pinboard-layout
, on the pinboard object under the cursor.
See the example in
examples/capi/graphics/pinboard-help.lisp
.
