MouseWatcherBase¶

class MouseWatcherBase¶

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.

MouseWatcherBase.add_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.

MouseWatcherBase.clear_regions()¶: Removes all the regions from the group.

MouseWatcherBase.find_region()¶: 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.

static MouseWatcherBase.get_class_type()¶

MouseWatcherBase.get_num_regions()¶: Returns the number of regions in the group.

MouseWatcherBase.get_region()¶: 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.

MouseWatcherBase.has_region()¶: Returns true if the indicated region has already been added to the MouseWatcherBase, false otherwise.

MouseWatcherBase.hide_regions()¶: Stops the visualization created by a previous call to show_regions().

MouseWatcherBase.is_sorted()¶: Returns true if the group has already been sorted, false otherwise.

MouseWatcherBase.output()¶

MouseWatcherBase.remove_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.

MouseWatcherBase.set_color()¶: Specifies the color used to draw the region rectangles for the regions visualized by show_regions().

MouseWatcherBase.show_regions()¶: 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.

MouseWatcherBase.sort_regions()¶: Sorts all the regions in this group into pointer order.

MouseWatcherBase.update_regions()¶: Refreshes the visualization created by show_regions().

MouseWatcherBase.write()¶
