tooltips have unique
ids. The second and subsequent
tooltips with the same
id get ignored.
type must always be
“label”, this is currently ignored but should be set for
future extensibility.
elements'
tooltip attribute refers to a tooltip
with the given
id. More then one
element may refer to the same tooltip.
Only supported theme widgets have a
tooltip attribute;
named element widgets are under the callbacks'
control and only the callbacks can set their tooltips.
tooltips' contents are the same
as label widget's
label. This is equivalent to using a widget's
create_tooltip() to create a basic,
label tooltip.
<container tooltip="container-tooltip"> ... </container> <tooltip type="label" id="container-tooltip"> ... </tooltip>
container elements also
have optional tooltip attributes.
