Additional Inherited Members

- Public Member Functions inherited from MouseWatcherBase
 addRegion (MouseWatcherRegion region)
 Adds the indicated region to the set of regions in the group. It is an error to add the same region to the set more than once. More...
 
 clearRegions ()
 Removes all the regions from the group. More...
 
MouseWatcherRegion findRegion (str name)
 Returns a pointer to the first region found with the indicated name. If multiple regions share the same name, the one that is returned is indeterminate. More...
 
int getNumRegions ()
 Returns the number of regions in the group. More...
 
MouseWatcherRegion getRegion (int n)
 Returns the nth region of the group; returns NULL if there is no nth region. Note that this is not thread-safe; another thread might have removed the nth region before you called this method. More...
 
list getRegions ()
 
bool hasRegion (MouseWatcherRegion region)
 Returns true if the indicated region has already been added to the MouseWatcherBase, false otherwise. More...
 
 hideRegions ()
 Stops the visualization created by a previous call to show_regions(). More...
 
bool isSorted ()
 Returns true if the group has already been sorted, false otherwise. More...
 
 output (Ostream out)
 
bool removeRegion (MouseWatcherRegion region)
 Removes the indicated region from the group. Returns true if it was successfully removed, or false if it wasn't there in the first place. More...
 
 setColor (const LColor color)
 Specifies the color used to draw the region rectangles for the regions visualized by show_regions(). More...
 
 showRegions (const NodePath render2d, str bin_name, int draw_order)
 Enables the visualization of all of the regions handled by this MouseWatcherBase. The supplied NodePath should be the root of the 2-d scene graph for the window. More...
 
 sortRegions ()
 Sorts all the regions in this group into pointer order. More...
 
 updateRegions ()
 Refreshes the visualization created by show_regions(). More...
 
 write (Ostream out, int indent_level)
 
- Public Member Functions inherited from ReferenceCount
int getRefCount ()
 Returns the current reference count. More...
 
 ref ()
 Explicitly increments the reference count. User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically. More...
 
bool testRefCountIntegrity ()
 Does some easy checks to make sure that the reference count isn't completely bogus. Returns true if ok, false otherwise. More...
 
bool testRefCountNonzero ()
 Does some easy checks to make sure that the reference count isn't zero, or completely bogus. Returns true if ok, false otherwise. More...
 
bool unref ()
 Explicitly decrements the reference count. Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete(). More...
