DISABLE BUTTON ({*; }object)
| Parameter | Type | Description | |
| * | If specified, object is an Object Name (String) | ||
| If omitted, object is a Variable | |||
| object | Form Object | Object Name (if * is specified), or | |
| Variable (if * is omitted) |
Description
The command DISABLE BUTTON disables the form objects specified by object.
A disabled button or object does not react to mouse clicks and shortcuts, and is displayed dimmed or grayed out.
Note: Disabling a button or an object does not prevent you from changing its value programmatically.
If you specify the optional * parameter, you indicate an object name (a string) in object. If you omit the optional * parameter, you indicate a field or a variable in object. In this case, you specify a field or variable reference (field or variable objects only) instead of a string. For more information about object names, see the section Object Properties.
This command (despite what its name suggests) can be applied to the following types of object:
Button, Default Button, 3D Button, Invisible Button, Highlight Button
Radio Button, 3D Radio Button, Radio Picture
Check Box, 3D Check Box
Pop-up menu, Drop-down List, Combo Box, Menu/Drop-down list
Thermometer, Ruler
Note: It is not practical to use this command with an object that is assigned an automatic action, because 4D changes the state of the control when needed.
Examples
