Vote count: 0 I am populating a QGraphicsScene with instances of a custom item class (inherting QGraphicsPathItem). At some point during runtime, I try to remove an item (plus its children) from the scene by calling: delete pItem; This automatically calls QGraphicsScene::removeItem(), however it also leads to a crash in the class QGraphicsSceneFindItemBspTreeVisitor during the next repaint. asked 24 secs agoPhilip Allgaier 1 Answer Vote count: 0 TL;DR: The solution is to ensure that QGraphicsItem::prepareGeometryChange() gets called before the item's removal from the scene. The problem is that during the item removal from the scene, the scene inteal index was not properly updated, resulting ...

Vote count: 0 I want to add an whole object to my listview using Firebase. Have been illustration this with a image because sometimes an image is just easier than text. Firebase tutorials show how to retu each child as an item and display it with Firebase UI and I want to almost do the same thing but the difference is that I want the whole object to be the child and the childs inside that object will be additional information for each listitem. So in my image I have object Camping and the "Mountains", "Nature", "Place".

Vote count: 0 (Leaing Swift as 1st programming language) (1st time using stack) Hi, I am creating a local delivery app where users will be messaging me to place orders for delivery. However users can see every other user registered on the app and message them. How would I make it so that just 1 primary admin can see and message every other users, whereas users can only message me? I'm using Firebase for back-end.

Vote count: 0 I have to produce several hundred USB drives and am using a supplier who can preload files onto each one. What I'd like to do is replace the default drive icons— —with a custom icon I've created. I know about the copy+paste method, but the number of drives makes that prohibitive. I know about the .VolumeIcon.icns method, but it seems that too requires another step, namely ruing SetFile -a C .VolumeIcon.icns on each drive (if I'm mistaken, please correct me). What I'm looking for is a way to have the supplier load a (.icns) file onto each drive that will automatically set the drive's icon. One thread hinted at a way of adding 3 files, but I'm not sure how to come by these. Any i...

I can print the barcode labels from Chrome, after choosing the right Paper Size and it works flawlessly.
