ICommandEventArgs.Argument

Syntax

Argument: Variant;

Description

The Argument property returns the value of the argument of the command that was sent to the form.

Example

Suppose that we should send command from the SOURCEFORM form to the DESTINATIONFORM form. To do this, add a link to the DESTINATIONFORM form to the inspector of assemblies in the SOURCEFORM form. The word Public must be added to the description of the class of the DESTINATIONFORM form.

After all actions the text of the macro for the SOURCEFORM form should look as follows:

Class SOURCEFORMForm: Form

Button1: Button;

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);

Var

DestForm: DESTINATIONFORMForm;

Res: string;

Begin

DestForm := New DESTINATIONFORMform.CreateForm;

Res := DestForm.SendCommand("Square", 21) As String;

WinApplication.InformationBox(Res);

End Sub Button1OnClick;

End Class SOURCEFORMForm;

For the DESTINATIONFORM form:

Public Class DESTINATIONFORMForm: Form

Sub DESTINATIONFORMFormOnCommand(Sender: Object; Args: ICommandEventArgs);

Begin

If Args.Command = "Sum" Then

Args.Result := Args.Argument + Args.Argument;

End If;

If Args.Command = "Square" Then

Args.Result := Args.Argument * Args.Argument;

End If;

If Args.Command = "Difference" Then

Args.Result := Args.Argument - Args.Argument;

End If;

End Sub DESTINATIONFORMFormOnCommand;

End Class DESTINATIONFORMForm;

After the Button1 button has been pressed on the SOURCEFORM form the 21 value is sent to the DESTINATIONFORM form that squares this value and returns the result.
