Tooltips

DRAFT - WIP

Tooltips are widgets that appear bellow other widget after user hover mouse pointer on that other widget. Showcase

Tooltip can be attached to any actor, only one tooltip can be attached to actor at the same time.

Creating tooltip for label:

VisLabel labelWithTooltip = new VisLabel("label with tooltip");
new Tooltip(labelWithTooltip, "this label has a tooltip");

Dettaching any tooltip from actor:

Tooltip.removeTooltip(someActor)

As you can see tooltips are not part of actor (i.e. method like actor.setTooltip(...) does not exist). Tooltips works by attaching listener to target actor, if you remove that listener from actor(for example by calling actor.clearListeners()) then you have to attach tooltip again by calling tooltip.attach(), you can also remove tooltip manually by calling tooltip.detach(),

Tooltip target can be changed by calling tooltip.setTarget(Actor newTarget), this will automatically detach tooltip from old target and attach it to new target.

VisImageButton

VisImageButton has constructor that allows to add tooltip along side with button icon, for example:

VisImageButton exploreButton = new VisImageButton(Assets.getIcon("folder-open"), "Explore");
VisImageButton settingsButton = new VisImageButton(Assets.getIcon("settings-view"), "Change view");
VisImageButton importButton = new VisImageButton(Assets.getIcon("import"), "Import");

(Assets class is part of VisEditor, getIcon(...) returns Drawable)
