[Interest] simple crash with QGraphicsScene

Hello! I have reproduced a crash with QGraphicsView where you: - add a single item in the middle of the scene, - resize (shrink) the window with the mouse so the item is not fully visible - resize (grow) the window again - ***the issue happens right when item is fully visible again.*** Any idea h

[Interest] Child QWidget fade-in with QGraphicsOpacityEffect

I have a QGraphicsView (under QMainWindow) with a pop-up QWidget for item properties which fades in with QGraphicsOpacity effect. The problem is that when I start the animation the outer frame border of the widget fades in as expected, but the contents of the widget remains transparent until I c

[Interest] Slow refresh rate on QPropertyAnimation => pos for child widget?

Hello! I am getting pretty good refresh rates on QPropertyAnimation for QGraphicsScene, as the interval set in the qt source is for 60fps. But animating a child widget’s position looks more like 20fps. The widget in question is a child of the QGraphicsView. See the following screencast, which i

[Interest] QMake: Way to set capabilities for Xcode project?

I am dependent on a tool that uses qmake to regenerate an xcodeproject whenever I add a source file, and so I always have to find the way to make any changes to the Xcode project within the .pro file. I have done well until this point with the Info.plist file. But now I need to be able to enabl

I am generating an Xcode project from a .pro file and want to set an xcconfig file as the build configuration for a particular target in the project. This means that I need to edit the .pro file to: 1) add the xcconfig file to the project 2) set the xcconfig in the build settings for the target

[Interest] Pan-scroll gesture for QGraphicsView on iOS?

The pan gesture scrolls qgraphicsview just fine on macOS, but the same code doesn't work on iOS. Is there something special I need to do there? Thank you! smime.p7s Description: S/MIME cryptographic signature ___ Interest mailing list Interest@qt-proje

[Interest] Building & Running on High Sierra

Is there a version or commit that runs on high sierra? I am getting segfaults in a 300-or-so deep stack of calls in libqcocoa.dylib using the branch on git (need to try again to get a useful stack trace). Qt-5.9.1 fails to build in qcoregraphics.mm like so: dor/pyqt-sysroot-base/src/qt-everywh

[Interest] Synchronous painting on QGraphicsScene

Hi there! I have a graph-ish diagram app where dragging some objects (like nodes) necessitates dragging other objects (like connecting edges). However, if I update an edge from the mouse event or ItemChanged(position) event then the edge isn’t painted until the next paint event. At times, this

That is correct, this did fix the antialiasing issue at the expense of performance. I suppose it is a trade off. > On Oct 7, 2017, at 1:09 AM, Christian Gagneraud wrote: > >> On 7 October 2017 at 16:11, Patrick Stinson wrote: >> >> Hello! >> >> I am se

Re: [Interest] Synchronous painting on QGraphicsScene

possible to implement painting in a synchronous way, where all paint events which result from a single mouse event are done in the same buffer frame. Make sense? > On Oct 7, 2017, at 1:01 AM, Christian Gagneraud wrote: > > On 7 October 2017 at 16:08, Patrick Stinson wrote: >> Hi there
