Detailed Description

The interface to the functionality for using the Grip Manager.

This class contains key functionality for using grips. It contains functionality for setting which grip is active in addition to various options for how grips are displayed and manipulated. You get this interface by calling GetIGripManager(). This class is created by the system.

See also: IGRIPMANAGER_INTERFACE; GetIGripManager()

Member Function Documentation

◆ SetGripActive()

virtual void SetGripActive ( IBaseGrip * grip )

pure virtual

Make the grip active and show it.

Parameters

[in] grip The grip that will turn active and have its UI displayed. If another grip was active, that grip becomes inactive. Only one grip may be active at a time. If the value is NULL this functions acts like SetGripsInactive.

◆ SetGripsInactive()

virtual void SetGripsInactive ( )

pure virtual

Inactivate the current active grip.

If no grip is active, nothing happens.

◆ GetActiveGrip()

virtual IBaseGrip* GetActiveGrip ( )

pure virtual

Get the current active grip.

Returns: Returns the current active grip. If no grip is active, returns NULL.

◆ ActivateGripItem()

virtual bool ActivateGripItem	(	int	whichItem,
		bool	active
	)

pure virtual

Set whether or not a particular grip item of the active grip will be activated or not.

By default, all grip items are activated and interactive.

Parameters

[in]	whichItem	The zero based index for the item for which we will be activate or not. If out of range of the number of grip items, on the active grip this function will do nothing.
[in]	active	If true the item is active and can get manipulated, if false, the item is disabled and greyed out in the viewport.

Returns: true if the operation succeeded, false otherwise.

◆ IsGripItemActive()

virtual bool IsGripItemActive ( int whichItem )

pure virtual

Get whether or not a particular grip item of the active grip is active or not.

Parameters

[in] whichItem The zero based index for the item for which we are checking to see if it's active or not.

Returns: Returns true if the item is active, false if the item is not and it's been disabled. If the whichItem parameter is out of range or no grip is active then this function will return false.

◆ HideGripItem()

virtual bool HideGripItem	(	int	whichItem,
		bool	hide
	)

pure virtual

Set whether or not a particular grip item of the active grip will be visible or not.

By default, all grip items are visible.

Parameters

[in]	whichItem	The zero based index for the item for which we will display or hide. If out of range of the number of grip items, on the active grip this function will do nothing.
[in]	hide	If true the item is hidden and is not displayed, if false, the item is displayed. Note that by default all grip items are visible. Note in order to see the change in the UI, you must call ResetAllGripUI().

Returns: true if the operation succeeded, false otherwise.

◆ IsGripItemVisible()

virtual bool IsGripItemVisible ( int whichItem )

pure virtual

Get whether or not a particular grip item of the active grip is visible or not.

Parameters

[in] whichItem The zero based index for the item for which we are checking to see if it's visible.

Returns: Returns true if the item is visible, false if the item is not. If the whichItem parameter is out of range or no grip is active then this function will return false.

◆ ResetGripUI()

virtual bool ResetGripUI ( int whichItem )

pure virtual

Tell that grip item it should reset its UI, usually since some value has changed and needs to get refleced in the UI.

When called that item will call the necessary IBaseGrip functions, such as GetValue, to reset and recreate the UI,

Parameters

[in] whichItem The zero based index for the item for which needs to reset its UI.

Returns: Returns true if the item is active, false if the item is not. If the whichItem parameter is out of range or no grip is active then this function will do nothing and return false.

◆ ResetAllUI()

virtual void ResetAllUI ( )

pure virtual

Convienence function to reset all of a grip's UI.

Resetting the UI will cause the system to get the various values from each grip item.

◆ SetShow()

virtual void SetShow ( bool val )

pure virtual

Show grips.

By default grips are shown when one is active.

Parameters

[in] val If true grips will be shown, if false no grips will be shown even if active.

◆ GetShow()

virtual bool GetShow ( ) const

pure virtual

Get if grips are shown.

Returns: If true grips will be shown,if false no grips will be shown even if active.

◆ GetXYLocation()

virtual void GetXYLocation	(	float &	x,
		float &	y
	)

pure virtual

Get the location of the grip in screen space.

Parameters

[out]	x	The x location of the grip in screen space.
[out]	y	The y location of the grip in screen space.

◆ SetLocation()

virtual void SetLocation	(	int	x,
		int	y
	)

pure virtual

Set the location of the grip in screen space.

Parameters

[in]	x	The x location of the grip in screen space that you want the grip's upper right corner to be placed.
[in]	y	The y location of the grip in screen space that you want the grip's upper right corner to be placed.

◆ SetCenterOnSelected()

virtual void SetCenterOnSelected ( bool val )

pure virtual

Set whether or not the grip stays centered around the current selection gizmo.

Parameters

[in] val If true the grip stays centered around the current selection gizmo, if false the grip stays fixed at it's current viewport location.

◆ GetCenterOnSelected()

virtual bool GetCenterOnSelected ( ) const

pure virtual

Get whether or not the grip stays centered around the current selection gizmo.

return If true the grip stays centered around the current selection gizmo, if false the grip stays fixed at it's current viewport location.

◆ SetCenterXYPos()

virtual void SetCenterXYPos	(	float	x,
		float	y
	)

pure virtual

Set the normalized x and y location of the grip in the active viewport.

These values are used if GetCenterOnSelection returns false.

Parameters

[in]	x	The normalized [0-1] x location of the grip in the active viewport. So a value of 0.5 will place the grip in the center of viewport.
[in]	y	The normalized [0-1] y location of the grip in the active viewport. So a value of 0.5 will place the grip in the center of viewport.

◆ GetCenterYPos()

virtual float GetCenterYPos ( ) const

pure virtual

Get the normalized y location of the grip in the active viewport.

These values are used if GetCenterOnSelection returns false.

Returns: The normalized [0-1] y location of the grip in the active viewport. So a value of 0.5 will place the grip in the center of viewport.

◆ GetCenterXPos()

virtual float GetCenterXPos ( ) const

pure virtual

Get the normalized x location of the grip in the active viewport.

These values are used if GetCenterOnSelection returns false.

Returns: The normalized [0-1] x location of the grip in the active viewport. So a value of 0.5 will place the grip in the center of viewport.

◆ SetSelectedOffsetXY()

virtual void SetSelectedOffsetXY	(	int	offsetPixelX,
		int	offsetPixelY
	)

pure virtual

Set the x and y pixel offset from the current selection gizmo where the grip will get placed.

Returns: The x pixel offset off of the current selection where the grip will get placed.

◆ GetSelectedOffsetY()

virtual int GetSelectedOffsetY ( ) const

pure virtual

Get the y pixel offset from the current selection gizmo where the grip will get placed.
