Bases:
PandaNode
The “top” node of the new Panda GUI system. This node must be parented to the 2-d scene graph, and all PG objects should be parented to this node or somewhere below it. PG objects not parented within this hierarchy will not be clickable.
This node begins the special traversal of the PG objects that registers each node within the
MouseWatcher
and forces everything to render in a depth-first, left-to-right order, appropriate for 2-d objects.Inheritance diagram
- static getClassType() TypeHandle
- getGroup() MouseWatcherGroup
Returns the
MouseWatcherGroup
pointer that thePGTop
object registers its PG items with, or NULL if theMouseWatcher
has not yet been set.
- getMouseWatcher() MouseWatcher
Returns the
MouseWatcher
pointer that thePGTop
object registers its PG items with, or NULL if theMouseWatcher
has not yet been set.
- getStartSort() int
Returns the sort index that is assigned during the traversal to the first
PGItem
that is discovered during traversal. SeesetStartSort()
.
- setMouseWatcher(watcher: MouseWatcher)
Sets the
MouseWatcher
pointer that thePGTop
object registers its PG items with. This must be set before the PG items are active.
- setStartSort(start_sort: int)
Specifies the sort index that is assigned during the traversal to the first
PGItem
that is discovered during traversal. SubsequentPGItems
will be assigned consecutively higher sort indexes.This number is used by the
MouseWatcher
system to rank the clickable mouse regions in the same order in which the items are rendered, so that items on top will receive mouse priority.Normally, it makes the most sense to leave this initial value at its default value of 0, unless you need the
PGItems
to have a particular sort value with respect to some other objects in the scene (particularly with a secondPGTop
node).
