Member Function Documentation

virtual HWND GetHwnd ( )

pure virtual

Remarks

Returns the handle of the control.

virtual void Enable ( BOOL  onOff = TRUE )

pure virtual

Remarks

This method is used to enable the control so it may be operated by the user.

Parameters

onOff

TRUE to enable; FALSE to disable.

Implemented in IVertToolbar.

virtual void Disable ( )

pure virtual

Remarks

This method is used to disable the control so it may not be selected or used. When disabled, the control usually appears grayed out.

virtual BOOL IsEnabled ( )

pure virtual

Remarks

This returns TRUE if the control is enabled and FALSE if it is disabled.

virtual void Enable2 ( BOOL  onOff = TRUE )

pure virtual

Remarks

This method is used internally and should not be called by plug-in developers. This second enable function is used to disable and enable custom controls when the associated parameter has a non-keyframable parameter. The effective enable state is the AND of these two enable bits.

For example, when a parameter has a controller plugged into it, and the controller is not keyframable, any spinner control associated with it won't be effective. That's because the controller doesn't take input – it only outputs values. To prevent the user from being confused by the ineffectiveness of the spinner the control it's automatically disabled by the system using this method.

Parameters

onOff

TRUE to enable; FALSE to disable.

virtual INT_PTR Execute ( int  cmd, ULONG_PTR  arg1 = 0, ULONG_PTR  arg2 = 0, ULONG_PTR  arg3 = 0  )

inlinevirtual

Remarks

This is a general purpose function that allows the API to be extended in the future. The 3ds Max development team can assign new cmd numbers and continue to add functionality to this class without having to 'break' the API.

This is reserved for future use.

Parameters

cmd	The command to execute.
arg1	Optional argument 1 (defined uniquely for each cmd).
arg2	Optional argument 2.
arg3	Optional argument 3.

Returns

An integer return value (defined uniquely for each cmd).

Default Implementation:

{ return 0; }

{ return 0; }

virtual void SetTooltip ( bool  bEnable, const MCHAR *  text  )

pure virtual

Sets a tooltip for the custom control.

This method allows for turning on or off the tooltip for a custom control.

Parameters

bEnable	- if true, the tooltip is enabled, otherwise disabled. When disabled, the tooltip won't be displayed when the the mouse hovers on top of the control. Enabling the tooltip repeatedly will have the same effect as enabling it once.
text	- pointer to a string representing the text to be displayed in the tooltip window. This parameter is ignored when the tooltip is being disabled.

CoreExport void UpdateEnableState	(	Animatable *	anim,
		int	subNum
	)

Helper function to disable or enable this UI control based on whether the Animatable associated with it is keyframable or not (locked parameter or scripted parameters are not keyframable).

When a UI control is associated with a parameter residing within a parameter block with the optional p_ui tag then the control will be automatically disabled when the parameter is non-keyframable and this method does not need to be used. When the control is not using that automatic association this helper method can be used. Caller needs to identify the parameter associated to the control as the subanim number of an Animatable.

Parameters

[in]	anim	The parent of the Animatable this control is associated with (if NULL, this method will do nothing).
[in]	subNum	The subanim number of the Animatable associated with this control. For IParamBlock2 use IParamBlock2::GetAnimNum to get subNum from ParamID (see sample code, for instance maxsdk\samples\materials\stdShaders.cpp).
