eYe magnet: contditional formatting of fields
The "eYe magnet" (also called conditional formatting) consists in modifying the visual aspect of a control in order to attract the user's attention to this control. WINDEV allows you to automatically modify this visual aspect according to a set of conditions. For example, a control for which the input is mandatory will be displayed on a red background as long as its content remains empty. The eYe magnet feature applies to the following controls: - Edit controls.
- Combo Box controls.
- Columns of Table controls in input mode.
- Columns of TreeView Table controls in input mode.
- Cells of Pivot Table control.
