Description
This property may be used to cause a Form or SubForm to be displayed on top of all other windows, even those owned by other applications.
Normally, Forms are brought to the front when they receive the input focus. Forms that do not have the input focus may be partially obscured by the one that does. If OnTop is set to 1, the Form or SubForm remains at the front even if it doesn't have the input focus. Indeed, it may partially obscure the Form that does have the focus. The default value is 0 (normal).
More than one Form may have OnTop set to 1. If so, these Forms appear on top of all others, but may overlap one another. Other applications may also have windows with this property.
For a graphical object, the OnTop property controls how it is drawn in a Grid relative to the grid lines and cell text. OnTop is applicable only if the graphic is the child of a Grid and is otherwise ignored.
| 0 | Graphical object is drawn behind grid lines and cell text |
| 1 | Graphical object is drawn on top of grid lines but behind cell text |
| 2 | Graphical object is drawn on top of grid lines and cell text |
