Setting the Framework Affinity for a Data Module

Go Up to Using Data Modules

Data modules are initially framework-neutral. In order to use framework-specific library elements, you need to set the platform affinity by selecting a framework-specific value for the ClassGroup pseudo-property.

To set the framework affinity for a data module:

1. Create or open a data module. For more information, see Creating and Editing Standard Data Modules.
2. Select the data module in the Form Designer.
3. In the Object Inspector, locate the ClassGroup pseudo-property.
4. To set the framework affinity for the data module, select one of the framework-specific values for ClassGroup, as follows:
   • Vcl.Controls.TControl - sets the VCL framework, including RTL elements that are not framework-specific.
   • FMX.Controls.TControl - sets the FMX framework, including RTL elements that are not framework-specific.
   • System.Classes.TPersistent - the default setting, indicates framework neutrality and includes only RTL elements that are not framework-specific.
