This represents a collection of MouseWatcherRegions that may be managed as a group.
This is the base class for both MouseWatcherGroup and MouseWatcher, and exists so that we don't have to make MouseWatcher inherit from ReferenceCount more than once.
addRegion | ( | MouseWatcherRegion | region | ) |
Adds the indicated region to the set of regions in the group.
It is no longer an error to call this for the same region more than once.
clearRegions | ( | ) |
Removes all the regions from the group.
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.
|

int getNumRegions | ( | ) |
Returns the number of regions in the group.
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.
list getRegions | ( | ) |
bool hasRegion | ( | MouseWatcherRegion | region | ) |
Returns true if the indicated region has already been added to the MouseWatcherBase, false otherwise.
hideRegions | ( | ) |
Stops the visualization created by a previous call to show_regions().
bool isSorted | ( | ) |
Returns true if the group has already been sorted, false otherwise.
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.
setColor | ( | const LColor | color | ) |
Specifies the color used to draw the region rectangles for the regions visualized by show_regions().
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.
sortRegions | ( | ) |
Sorts all the regions in this group into pointer order.
updateRegions | ( | ) |
Refreshes the visualization created by show_regions().
write | ( | Ostream | out, |
int | indent_level | ||
) |
MouseWatcherRegion regions[] |
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.
bool sorted |
Returns true if the group has already been sorted, false otherwise.
