TIWLink

TIWLink

The TIWLink control allows the developer to add a "link like" control to the IW forms. The Caption of the control is shown as a HTML link but it does not work as an usual HTML link, ie, it does not open a new page automatically, for example. The developer needs to use one of the control’s events to execute any code you want to associate with the IWLink control.

TIWLink = class(TIWCustomControl)
