Setting Tooltips

Gadgets can be associated with a tooltip. A tooltip is short explanatory text that is displayed when the user places the mouse pointer over a gadget. By default, tooltips are supported by the gadget holders. If you want to use tooltips outside gadget holders, use the class IlvToolTipHandler.

Creating a Tooltip

A tooltip is an instance of the IlvToolTip class. To create a tooltip, call:

IlvToolTip* tooltip = new IlvToolTip(“This is a test”);

Attaching a Tooltip to a Gadget

You can attach a tooltip to a gadget with the member function IlvGraphic::setNamedProperty since IlvToolTip is a subclass of the IlvNamedProperty class:

gadget->setNamedProperty(new IlvTooltip(“This is a test”));

Enabling and Disabling Tooltips

You can enable or disable tooltip management at the application level using the static member function Enable.

Specific Tooltips

Some gadgets have their own tooltip mechanism, including IlvToolBar, IlvTreeGadget, IlvMatrix, IlvStringList, and IlvPopupMenu.

For more information, refer to the sections dedicated to these gadgets.
