Hi Jon, Many thanks for your excellent work. One of possible ways to solve your problem is to: - Add an additional field (say, m_drawPriority) in VIEW_ITEM_DATA containing the drawing priority - Modify VIEW::redrawRect() and VIEW::drawItem to first collect all drawable items, sort them by m_drawPriority and then draw. - The m_drawPriority could be accessed by additional methods in the VIEW class and by default initialized to subsequent values as items are added to a VIEW. - Sorting could be optional, for large PCB views it might affect performance. Cheers, Tom PS. If you have time, feel free to C++11-ize the VIEW code ;-) > > Thanks, > Jon > > > _______________________________________________ > Mailing list: https://launchpad.net/~kicad-developers > Post to : [email protected] > Unsubscribe : https://launchpad.net/~kicad-developers > More help : https://help.launchpad.net/ListHelp > _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
