IInputOnElementEventHandler.HandleInputOnElementEvent (METH) ¶ METHOD HandleInputOnElementEvent : BOOL This method will be called when an input on a visualization element was executed. The event is only triggered if any action is performed in the element. The following actions can be triggered: - Optical change in the element - e.g. selection changes - Change of an IEC variable by the element - Call a configured method - e.g. OnMouseDown OnMouseEnter and OnMouseLeave do not trigger this event. The event is triggered on an area in the element if this area can cause a change. At least one event is triggered by any VisuEnumInputInputOnElementType. It can also happen that several different VisuEnumInputOnElementType events are triggered by one input. e.g. sometimes only VisuEnumInputOnElementType.MouseDown, sometimes only VisuEnumInputOnElementType.MouseUp, sometimes both events VisuEnumInputOnElementType.MouseDown and VisuEnumInputOnElementType.MouseUp. RETURN: TRUE - When the handler has handled this event and it should not be handled by someone else FALSE - When the event is not handled by this handler InOut: Scope Name Type Return HandleInputOnElementEvent BOOL Input event VisuStructInputOnElementEvent

IMouseEventHandler.HandleMouseBtnEvent (METH) ¶ METHOD HandleMouseBtnEvent : BOOL This method will be called when a mouse button is pressed. RETURN: TRUE - When the handler has handled this event and it should not be handled by someone else FALSE - When the event is not handled by this handler InOut: Scope Name Type Comment Return HandleMouseBtnEvent BOOL Input bMouseUpEvent BOOL The event type. The value is true if a mouse button was released. btMouseBtn BYTE Information about the button that was pressed or released. At the moment this value is not yet used and will always have the value 0! ptMouse VisuStructPoint The position where the mouse event was raised. The coordinates of this point are relative to the currently active toplevel visualization, even when best fit is activated. pClient POINTER TO VisuStructClientData A pointer to the client structure were the event occurred.

IMouseEventHandler.HandleMouseMoveEvent (METH) ¶ METHOD HandleMouseMoveEvent : BOOL This method will be called when the mouse was moved. RETURN: TRUE - When the handler has handled this event and it should not be handled by someone else FALSE - When the event is not handled by this handler InOut: Scope Name Type Comment Return HandleMouseMoveEvent BOOL Input ptMouse VisuStructPoint The position where the mouse was moved to. The coordinates of this point are relative to the currently active toplevel visualization, even when best fit is activated. pClient POINTER TO VisuStructClientData A pointer to the client structure were the event occurred.

IKeyEventHandler.HandleKeyEvent (METH) ¶ METHOD HandleKeyEvent : BOOL This method will be called after a key event is released. RETURN: TRUE - When the handler has handled this event and it should not be handled by someone else FALSE - When the event is not handled by this handler InOut: Scope Name Type Comment Return HandleKeyEvent BOOL Input bKeyUpEvent BOOL The event type. The value is true if a key up event was released. dwKey DWORD The key code dwModifiers DWORD The modifiers. Possible values are: VISU_KEYMOD_SHIFT : DWORD := 1; VISU_KEYMOD_ALT : DWORD := 2; VISU_KEYMOD_CTRL : DWORD := 4; pClient POINTER TO VisuStructClientData A pointer to the client structure were tje event was released
