Detailed Description

A manager to control the usage of the viewport buttons.

A Manager that the developer uses to register viewport buttons. It also contains helper function to provide global hittesting and per button hittesting. The developer can use these from within the OnAction callback. The manager is not responsible for deleting the manager. The developer should Unregister and then delete the button
To use IViewportButtonManager simply use static_cast<IViewportButtonManager*>(GetCOREInterface(IVIEWPORTBUTTONMANAGER_INTERFACE ))

Member Function Documentation

◆ RegisterButton()

virtual void RegisterButton ( IViewportButton button)
pure virtual

Register a new button.

Register a new button with the manager. The system will check against buttons already registered

Parameters
buttonThe new button to register

◆ UnRegisterButton()

virtual void UnRegisterButton ( IViewportButton button)
pure virtual

Remove a previously registered button.

Remove a button already registered with the system. The manager will not delete the button, simply removes it from the table

Parameters
buttonThe button to remove

◆ IsButtonRegistered()

virtual bool IsButtonRegistered ( IViewportButton button) const
pure virtual

A query to check if a button is registered.

Check to see if the button is registered. Developers can use this to check to see if a button is registered before trying to register it

Parameters
buttonThe button to test against

◆ GetNumRegisteredButtons()

virtual int GetNumRegisteredButtons ( ) const
pure virtual

The total number of buttons.

The number of button registered with the manager

Returns
The total button count

◆ GetViewportButton()

virtual IViewportButton* GetViewportButton ( int  index)
pure virtual

Access an indivdual button.

Access to a specfiic button by index.

Parameters
indexThe index of the button to acess
Returns
The actual button, or NULL if index is invalid

◆ EnableButtons()

virtual void EnableButtons ( bool  val)
pure virtual

globally enable/disable the viewport buttons

A global method for enabling the viewport button. If the buttons are disabled, nothing will be displayed or processed.

Parameters
valTRUE if the buttons are to be enabled

◆ GetButtonsEnabled()

virtual bool GetButtonsEnabled ( ) const
pure virtual

Globally acces whether the viewport buttons are enabled.

A global method for querying viewport buttons enabled status. If the buttons are disabled, nothing will be displayed or processed.

Returns
TRUE if enabled

◆ OnAction()

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

Sends the OnAction command.

Send the OnAction command to all registered viewports

Parameters
hwndThe Window handle where the action we performed
gwA pointer to the GraphicsWindow
hitLocThe point where the action occured - this allow the button to perform a hittest.
actionThe type of action
Returns
TRUE if an action was performed.

◆ OnUpdate()

virtual bool OnUpdate ( HWND  hwnd,
ViewExp vpt 
)
pure virtual

Send the OnUpdate command.

Sends the OnUpate command to all registered viewports

Parameters
hwndThe Window handle issueing the update request
vptA pointer to current View
Returns
TRUE if an update was implemented.

◆ HitTest() [1/2]

virtual bool HitTest ( HWND  hwnd,
GraphicsWindow gw,
IPoint2  stringStartLoc,
IPoint2  hitLoc,
const MSTR string 
)
pure virtual

Provides a single hittest of the text.

Utility function to perform hittesting on the supplied string and the location provided The derived IViewportButton can use this for localised hit testing, for example in the OnAction method

Parameters
hwndThe window handle
gwGraphicsWindow pointer from the active viewport
stringStartLocThe start location of the supplied string
hitLocThe mouse position
stringThe label to hittest against
Returns
TRUE if the mouse point intersects the string rectangle

◆ HitTest() [2/2]

virtual bool HitTest ( HWND  hwnd,
GraphicsWindow gw,
IPoint2  hitLoc 
)
pure virtual

Global hittesting on all registered buttons.

Utility function to allow hittesting on all buttons registered. It will simply return TRUE on the first successful hit test on the button label

Parameters
hwndThe window handle
gwThe GraphicsWindow for the active viewport
hitLocThe mouse position
Returns
TRUE if the mouse point intersects any button's label

◆ DrawButtons()

virtual void DrawButtons ( ViewExp vpt,
Rect rect = NULL 
)
pure virtual

Render the buttons.

Global function to draw each button registered in the system.

Parameters
vptThe current active viewport
rectIf none NULL, the complete viewport Rect is stored here.

◆ RefreshButtonDisplay()

virtual void RefreshButtonDisplay ( )
pure virtual

Utility function for forcing a refresh of the button display.
