has_tooltip
Description:
Enables or disables the emission of query_tooltip on status_icon
.
A value of true indicates that status_icon
can have a tooltip, in this case the status icon
will be queried using query_tooltip to determine whether it will
provide a tooltip or not.
Note that setting this property to true for the first time will change the event masks of the windows of this status icon to include leave-notify and motion-notify events. This will not be undone when the property is set to false again.
Whether this property is respected is platform dependent. For plain text tooltips, use tooltip_text in preference.
