IVisuStreamHandler (ITF) ¶ INTERFACE IVisuStreamHandler EXTENDS __SYSTEM.IQueryInterface This interface is the base interface of IVisuStreamReader and IVisuStreamWriter. Methods: EndOperation StartOperation Structure: EndOperation (Method) StartOperation (Method)

IVisuStreamHandler.EndOperation (METH) ¶ METHOD EndOperation This method will be called after a read or write operation on the current instance operation is finished or to cancel a not yet finished one. It is assumed that this call always succeeds. InOut: Scope Name Type Comment Input xCancel BOOL This value will be TRUE when the operation should be cancelled and FALSE if the call is only a notification about the end of the operation.

IVisuStreamHandler.StartOperation (METH) ¶ METHOD StartOperation : SysTypes.RTS_IEC_RESULT This method will be called when a read or write operation on the current instance operation is started. The return value can either be: ERR_OK: operation successfully started any other error code: starting an operation is not possible (at the moment) InOut: Scope Name Type Return StartOperation SysTypes.RTS_IEC_RESULT

IVisuUserEventManager.SetGestureEventHandler (METH) ¶ METHOD SetGestureEventHandler : BOOL This method assigns the eventhandler for gesture events. The method will return <c>TRUE</c> when there was no previous handler, and <c>FALSE</c> when there was a previous event handler. InOut: Scope Name Type Return SetGestureEventHandler BOOL Input handler IGestureEventHandler

IVisuUserEventManager.SetInputOnElementEventHandler (METH) ¶ METHOD SetInputOnElementEventHandler : BOOL This method assigns the eventhandler for input on element events. InOut: Scope Name Type Comment Return SetInputOnElementEventHandler BOOL TRUE - When there was no previous handler, i.e. the handler was registered successfully FALSE - When there was a previous event handler. Input itfInputOnElementEventHandler IInputOnElementEventHandler

IVisuUserEventManager.SetKeyEventHandler (METH) ¶ METHOD SetKeyEventHandler : BOOL This method assigns the eventhandler for key events. The method will return <c>TRUE</c> when there was no previous handler, and <c>FALSE</c> when there was a previous event handler. InOut: Scope Name Type Return SetKeyEventHandler BOOL Input handler IKeyEventHandler

IVisuManager3.GetPreviousShownVisu (METH) ¶ METHOD GetPreviousShownVisu : IVisualisation For the given client: Returns the previous shown visu, or null, if still the first visu is shown. InOut: Scope Name Type Return GetPreviousShownVisu IVisualisation Input pClientData POINTER TO VisuStructClientData

IVisuManagerBase (ITF) ¶ INTERFACE IVisuManagerBase EXTENDS __SYSTEM.IQueryInterface could be used by endusers too -> visible Methods: GetDialogManagerBase GetFrameManagerBase GetInternCommandManagerBase LastMainVisu NextMainVisu RegisterVisu SetMainVisu UnregisterVisu Structure: GetDialogManagerBase (Method) GetFrameManagerBase (Method) GetInternCommandManagerBase (Method) LastMainVisu (Method) NextMainVisu (Method) RegisterVisu (Method) SetMainVisu (Method) UnregisterVisu (Method)

IVisuManagerBase.GetDialogManagerBase (METH) ¶ METHOD GetDialogManagerBase : IDialogManagerBase InOut: Scope Name Type Return GetDialogManagerBase IDialogManagerBase

IVisuManagerBase.UnregisterVisu (METH) ¶ METHOD UnregisterVisu : INT InOut: Scope Name Type Return UnregisterVisu INT Input visu IVisualisation
