Purpose: To display pop-up help.

Description

The TipField is used to display pop-up help when the user moves the mouse pointer over an object.

Most of the GUI objects supported by Dyalog APL/W have a Tip and a TipObj property. TipObj specifies the name of, or ref to, a TipField object, and Tip specifies a "help" message. The TipField automatically pops-up to display the Tip when the user moves the mouse pointer over the object. It disappears when the user moves the mouse pointer away.

The TipField is a simple box with a 1-pixel black border in which the text specified by Tip is displayed. FCol, BCol and FontObj can be used to customise the appearance of the text within the box. FCol specifies the colour of the text; BCol specifies the background colour with which the box is filled. The default is black on yellow.

If you wish to display Tips for particular objects in different fonts and colours, you must create a separate TipField for each combination of colour and font you need.
