Member Function Documentation

virtual bool GetEnabled ( ) const

pure virtual

Access to the enabled flag.

Returns: TRUE if enabled

Implemented in ViewportTextButton.

virtual void SetEnabled ( bool v )

pure virtual

Set the Enabled flag.

If set to false, the button will not be drawn

Parameters

v	TRUE to enable, FALSE to disable the button.

Implemented in ViewportTextButton.

virtual MSTR GetLabel ( ) const

pure virtual

Access to the button text to be displayed in the viewport.

Returns: A string containing the current label to be displayed.

Implemented in ViewportTextButton.

virtual void SetLabel ( MSTR & label )

pure virtual

Set the text to be displayed in the viewport.

Parameters

label The string to set.

Implemented in ViewportTextButton.

virtual IPoint2 GetLocation ( ) const

pure virtual

Get the current location for the button.

Returns: The location of the button

Implemented in ViewportTextButton.

virtual void SetLocation ( IPoint2 & loc )

pure virtual

Set the location of the button.

Parameters

loc	The new location for the button

Implemented in ViewportTextButton.

virtual void SetColor ( Color & c )

pure virtual

Set the color for the button to be used.

Parameters

c	The color for button

Implemented in ViewportTextButton.

virtual Color GetColor ( ) const

pure virtual

Get the current color for the button.

Returns: The current color

Implemented in ViewportTextButton.

virtual bool ShowInActiveViewportOnly ( )

pure virtual

Defines whether the button is only shown in the current active viewport.

Returns: TRUE if only drawn in the active viewport

Implemented in ViewportTextButton.

virtual bool OnAction	(	HWND	hwnd,
		GraphicsWindow *	gw,
		IPoint2	hitLoc,
		IViewportButton::Action	action
	)

pure virtual

A callback to allow the button to perform an action, such as pop up a menu, or run a function.

Parameters

hwnd	The Window handle where the action we performed
gw	A pointer to the GraphicsWindow
hitLoc	The point where the action occured - this allows the button to perform a hittest.
action	The type of action

Returns: TRUE if an action was performed.

Implemented in ViewportTextButton.

virtual bool OnUpdate	(	HWND	hwnd,
		ViewExp *	vpt
	)

pure virtual

An update callback that can be used to update internal data structures.

The ViewportTextButton uses this to determine the Label to be used and location based on the current viewport being drawn.

Parameters

hwnd	The Window handle issueing the update request
vpt	A pointer to current View

Returns: TRUE if an update was implemented.

Implemented in ViewportTextButton.

virtual void Display	(	TimeValue	t,
		ViewExp *	vpt,
		int	flags
	)

pure virtual

Callback to display the button.

The ViewportTextButton uses this to draw text into the viewport using GraphicsWindow API. All drawing should go through this API - no GDI.

Parameters

t	The current time
vpt	THe viewport to draw into
flags

Implemented in ViewportTextButton.

virtual void GetViewportRect	(	TimeValue	t,
		ViewExp *	vpt,
		Rect *	rect
	)

pure virtual

Get the viewport rect for the button.

Parameters

t	The current time
vpt	The active viewport
rect	The result of the viewport rect is stored here.

Implemented in ViewportTextButton.
