Rad Studio 10.1 Berlin Dialog API Sample Source

Simplified Dialog API

Several procedures and functions to show dialog boxes are now deprecated, and have been replaced by the procedures and functions of the new IFMXDialogServiceAsync and IFMXDialogServiceSync platform services that provide support for synchronous and asynchronous dialog boxes, respectively.
The following table summarizes the API changes:

Deprecated Members New Members
  • FMX.Dialogs.MessageDlg
  • FMX.Dialogs.MessageDlgPos
  • FMX.Dialogs.MessageDlgPosHelp
  • FMX.Platform.IFMXDialogService.MessageDialog
  • FMX.Dialogs.InputBox
  • FMX.Dialogs.InputQuery
  • FMX.Platform.IFMXDialogService.InputQuery
