/*
|
||
|
|
* A Layout tool is a LightWave viewport tool whose draw() function
|
||
|
|
* takes a LWCustomObjAccess instead of a LWWireDrawAccess structure.
|
||
|
|
* It has the following handler functions.
|
||
|
|
*
|
||
|
|
* done destroy the instance when the user discards the tool.
|
||
|
|
*
|
||
|
|
* draw display a wireframe representation of the tool in a 3D
|
||
|
|
* viewport. Typically this draws the handles.
|
||
|
|
*
|
||
|
|
* help return a text string to be displayed as a help tip for
|
||
|
|
* this tool.
|
||
|
|
*
|
||
|
|
* dirty return flag bit if either the wireframe or help string
|
||
|
|
* need to be refreshed.
|
||
|
|
*
|
||
|
|
* count return the number of handles. If zero, then 'start' is
|
||
|
|
* used to set the initial handle point.
|
||
|
|
*
|
||
|
|
* handle return the 3D location and priority of handle 'i', or zero
|
||
|
|
* if the handle is currently invalid.
|
||
|
|
*
|
||
|
|
* start take an initial mouse-down position and return the index
|
||
|
|
* of the handle that should be dragged.
|
||
|
|
*
|
||
|
|
* adjust drag the given handle to a new location and return the
|
||
|
|
* index of the handle that should continue being dragged
|
||
|
|
* (often the same as the input).
|
||
|
|
*
|
||
|
|
* down process a mouse-down event. If this function returns
|
||
|
|
* false, handle processing will be done instead of raw
|
||
|
|
* mouse event processing.
|
||
|
|
*
|
||
|
|
* move process a mouse-move event. This is only called if the
|
||
|
|
* down function returned true.
|
||
|
|
*
|
||
|
|
* up process a mouse-up event. This is only called if the down
|
||
|
|
* function returned true.
|
||
|
|
*
|
||
|
|
* event process a general event: DROP, RESET or ACTIVATE
|
||
|
|
*
|
||
|
|
* panel create and return a view-type xPanel for the tool instance.
