#Variable Value
Type | Description |
---|---|
Tdx |
A reference to a “Expression Editor“ form class. |
#Remarks
Assign a reference to a TdxExpressionEditor class descendant to this global variable to replace the default “Expression Editor” dialog with a custom implementation. This is particularly useful if you need to show custom lists of categories and/or elements or adjust the default dialog layout.
The ShowExpressionEditor global procedure uses the FExpressionEditor variable to call the constructor of the active “Expression Editor” dialog form class.
