And it works great! Except when I try to adjust the additionalSafeAreaInsets of the view controller owning the view during dismissal. Im doing this by creating UIViewControllerAnimatedTransitioning-objects that animate the presented view's frame. I've created a custom UIViewControllerTransitioningDelegate that I use to animate a view from one view controller, to full-screen in another view controller.

Removing the binding of the old View allows the new View to be correctly bound. The second time it is called i set the flag to false, and i remove the binding.

Once the problem is understood, we need to figure out how to remove the binding of the old view when the view is dettached: well, to do this i used the fact that the VisualElement's Renderer property is set/modified when the element is attached and again when it is detached: The fist time it is called i set the isAttached flag to true. Now the problem is evident: when the ChildItem's AnimationInt property changes (tap on ROTATE RANDOM button) the old ChildItem-AnimatedGrid's Refresh is notified, and then the old View is rotated, but the new ramains unchanged (it does not rotate). When a ChildItem is added again ( remove Filter), a new view is created. When a ChildItem is removed ( do Filter), the old ChildItem-AnimatedGrid's Refresh property remains bound to the ChildItem's AnimationInt property. I believe this is a bug in Xamarin, and in your case i would file an issue in Github (although maybe MAUI will have this corrected.)

That's beyond my understanding.ĭisclaimer: it took me a long time to figure out what was going on here, and although i was able to fix the problem, i would not claim that i completely and perfectly understand it. However, for test purpose, i added in the control constructor, a lay followed by an animation call, and this call is working on filtered items. I am still not able to figure what's wrong. Once you click the 'Remove and add 2 parent', youĬan see that the removed/reinserted items does not rotate anymore.Basicaly, you can click the 'Rotate Random' multiple time to make.I made a sample project to reproduce the issue on github. However, i realy want to find a solution that would alow me to keep the listview control as switching to CollectionView would introduce to many other undesirable effect. I found that, if i replace the ListView control by a CollectionView, the problem disappear.

This does not seems to be an observable collection binding issue, as values inside parent and childs collection still update perfectly find.Ĭhanging CachingStrategy also have no impact on the issue. To be more precise, if parent item got removed from list, and then added again, childs of this parent will never animate again.įiltering the List consist of Removing/Inserting parents to the observable collection (m圜ollection.Remove(item), m圜ollection.Insert(index, item), using Collection methods from framework). Once i filter the list, subsequent call of AnimateItem will have no effect. Ggsave(sprintf('man/figures/png/%04i.png', frame), p, width = 6, height = 6)Įverything works fine until i start filtering the list. Geom_segment(data = segments_df, aes(x = x1, y = y1, xend = x2, yend = y2)) + Geom_point(aes(x, y, colour = as.factor(idx)), size = 4, na.rm=TRUE) + # Get the current positions of the circles as a ame Why not?Ĭlick in a tiny window to paint single pixels at a time. Only a program as cool as Chipmunk Basic would have a built-in spider icon (sprite #135). Move a spider around with your numeric keypad. I believe this was supposed to be like Space Invaders. The pre-3c versions don’t make much sense. Cutting edge.Ī square with a color of your choosing slides around a window. Move the mouse around and click to make red dots. Pistol-packing fun that leaves silly artifacts all over the window because it doesn’t erase everything it draws. It draws random pixels and beeps a lot and has no clear exit strategy. The cursor starts out wherever the mouse is when you first press an arrow button. I doubt they are very useful but here they are nevertheless.įor more Chipmunk Basic goodies look at my main Chipmunk Basic page or my cb-shpdraw page.ĭraw with the arrows. They’re more like tests or simple demos than actual programs. These programs are of 1996 or 1997 vintage.
