» Exkurs: Providing buttons with Hover effect

For depicting the Hover effect, one button is needed in the active state and one in the selected state. The active button is saved as a gif file with the prefix btn and the suffix 1.gif (e.g. btnBack1.gif). For the Hover effect, one button is required with the ending 3.gif (e.g. btnBack3.gif).

Name conventions and states for form buttons:

State	Example	Name convention
Activ		btnXXX1.gif
Inactiv		btnXXX3.gif
Actively selected		btnXXX5.gif
Pressed		btnXXX6.gif

The images are automatically exchanged as soon as the mouse pointer is moved over a form button. A JavaScript Eventhandler, which is registered for the MouseOver and MouseOut-Event in the file fw/def/jscript/controls.js, is responsible for this.

This script is automatically included in every HTML page by the default painter.
