 
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
.
