Description | Use the customKeys property to find out what customproperties an object has, and to create or delete custom properties. The customKeys lists the names of properties in the object's current customPropertySet. If the object has more than one custom property set, you must switch to the desired property set before checking the customKeys. The following example displays the custom properties in a custom property set called "Francois" :
Alternatively, the custom property set can be accessed using:
If you set the customKeys of an object, and the propertiesList contains a custom property that the object doesn't have, a custom property with that name is created. (A property name can be up to 255 characters long. The number of property names is limited only by LiveCode's total memory space.) The value of a newly-created custom property is empty. If you set the customKeys of an object and do not include the name of an existing custom property, that custom property is deleted. Setting the customKeys to empty deletes all custom properties in the current custom property set. | ||||||
