Description

The uhyperlink is a display-only widget that is activates by clicking it. In this respect, it behaves like ucmdbutton, so it can be used where space on a form is limited or you want a different appearance. Unlike a command button, the hyperlink widget can contain only string data.

A hand cursor appears as soon the pointer is above the text of uhyperlink widget. The focus rectangle is not visible when the Transparency property is set.

You can give the uhyperlink widget the same appearance as an HTML hyperlink in a web browser by using the font and color properties of the widget.

Activating Triggers

The uhyperlink widget is for display only, so triggers associated with data modification are never fired. You can, however, use all other field-level triggers as you wish. Typically, you might use the field-level detail trigger to activate another component or spawn a web browser with a URL, for example:

spawn "C:\Program Files\Internet Explorer\Iexplore.exe http://refdesk.whitepages.com/"

You can set the Hyperlink property to False to disable the Detail trigger functionality and the hand cursor. This is useful for creating what appears to be a transparent, dynamic label at runtime.
