FMX.Platform | IFMXDialogServiceAsync |
Description
Displays a dialog box with the specified message and an OK button.
ShowMessageAsync works asynchronously. Calls to ShowMessageAsync finish instantaneously, they do not wait for the user to close the dialog box. To work synchronously, use IFMXDialogServiceSync.ShowMessageSync. FMX.Dialogs.ShowMessage works differently depending on the run-time platform.
ShowMessageAsync receives the following parameters:
AMessageis the text message.ACloseDialogProcorACloseQueryEventis an optional anonymous method or event handler that is called after the user closes the dialog box.AContextis an optional object that you can provide as a context for the event handler assigned toACloseQueryEvent.
When the user closes the dialog box, ShowMessageAsync calls the specified anonymous method or event handler with the following arguments:
Sender(ACloseQueryEventonly) contains the specifiedAContext.AResultis the modal result value of the button used to close the dialog box.
To call ShowMessageAsync without the need of an instance of IFMXDialogServiceAsync, use TDialogServiceAsync.ShowMessage instead.
