Interaction with controls

By using a script, complex logic can be incorporated into a dialogue's operation. Let's illustrate this with a simple example. Modify the form like this:

Double-click on the “CheckBox” object to create an “OnClick” event handler and enter the following script:

PascalScript:

procedure CheckBox1OnClick(Sender: TfrxComponent);
begin
  Button1.Enabled := not CheckBox1.Checked;
end;

C++ Script:

void CheckBox1OnClick(TfrxComponent Sender)
{
  Button1.Enabled = !CheckBox1.Checked;
}

This code is the same as is used in Delphi. On running the report the button responds to the state of the check box.
