Ax formBuildDesign class

在dialog中返回一个formBuildDesign的object，利用这个object，可以加formdesign的control，例如button

static void AKBackupMorphXVCData(Args _args)
{
    SysDataExport           sysDataExport;
    SysDataImport           sysDataImport;

    FormRadioControl        radioResults;
    
    dialog.addText("Warning, if you choose Import, this will replace your VCS data and is not reversible!");
    
    // Add the radio button, name it anything
    fbImportExport = dialog.formBuildDesign().addControl(FormControlType::RadioButton, 'RadioButton1');
    fbImportExport.caption("Choose Import/Export");
    fbImportExport.items(2); 

    fbImportExport.item(1);
    fbImportExport.text("Export");
    
    fbImportExport.item(2);
    fbImportExport.text("Import");

    dialog.doInit();
    dialog.formRun().design().moveControl(fbImportExport.id());
    dialog.run();

                }
        }
        else if (radioResults.selection() == 1) // Import

                sysDataImport.parmFiletype(FileType::Binary);
                sysDataImport.run();

                versioncontrol.init();
            }
