TContentForm

 

This class is a specialization of TContentBase class. It is responsible for redirecting an URL to a IWForm instance, i.e., whenever your IntraWeb application receives a request which path matches the path registered for the TContentForm instance, the associated IWForm will be used to respond to the request.

Unit

IW.Content.Form

Class hierarchy

TObject -> TContentBase -> TContentForm

Methods

Create [Public]

Declaration: constructor Create(aFormClass: TIWAppFormClass; DoBeforeExecuteCallback: TBeforeExecuteHandlerProc = nil); reintroduce; overload;

Description: Constructs an instance of the class TContentForm and initializes its data.

Parameters:

  • aFormClass (TIWAppFormClass): The form class used with this content handler
  • DoBeforeExecuteCallback (TBeforeExecuteHandlerProc): Reference to a TBeforeExecuteHandler procecure. This event will be triggered before execution of the content handler.

Create [Public]

Declaration: constructor Create(const aFormClassName: string; DoBeforeExecuteCallback: TBeforeExecuteHandlerProc = nil); reintroduce; overload;

Description: Constructs an instance of the class TContentForm and initializes its data.

Parameters:

  • aFormClassName (string): Name of the IWAppForm class, e.g, 'TIWForm1'. This allows you to register a TContentForm instance using only the form class name. To use this type of registration, you must register the form class using Classes.RegisterClass() method, because IntraWeb will retrieve this class using RTL's FindClass() method.
  • DoBeforeExecuteCallback (TBeforeExecuteHandlerProc): Reference to a TBeforeExecuteHandler procecure. This event will be triggered before execution of the content handler.
