This event class both informs items that the mouse cursor is nearby and allows items to communicate with one another about whether each item will accept *potential* mouse events. It is common for multiple overlapping items to receive hover events and respond by changing their appearance. This can be misleading to the user since, in general, only one item will respond to mouse events. To avoid this, items make calls to event.acceptClicks(button) and/or acceptDrags(button). Each item may make multiple calls to acceptClicks/Drags, each time for a different button. If the method returns True, then the item is guaranteed to be the recipient of the claimed event IF the user presses the specified mouse button before moving. If claimEvent returns False, then this item is guaranteed NOT to get the specified event (because another has already claimed it) and the item should change its appearance accordingly. event.isEnter() returns True if the mouse has just entered the item's shape; event.isExit() returns True if the mouse has just left. cd|_||_d|_tj|_tj|_d|_||j|_ |j|_ |j|_ |j|_|j!|_|j%|_yd|_y)NFT)enter acceptableexitweakrefWeakValueDictionary_HoverEvent__clickItems_HoverEvent__dragItemsrrrrrrKrrNrr r!r$r%)r'r(rs r,r-zHoverEvent.__init__ s $ #779"668  &//1DN'113DO!*!7!7!9D "+"9"9";D %--/DM'113DODIr.c|jS)z;Returns True if the mouse has just entered the item's shape)rr2s r,isEnterzHoverEvent.isEnterrdr.c|jS)z:Returns True if the mouse has just exited the item's shape)rr2s r,isExitzHoverEvent.isExit s yyr.cn|jsy||jvr|j|j|<yy)aRInform the scene that the item (that the event was delivered to) would accept a mouse click event if the user were to click before moving the mouse again.
