[Interest] sin wave with QPainterPath between two points

Hello! I want to figure out how to draw a sin wave between two QPointF’s using QPainterPath. Calculating the cubic control points seems like the best way, but I am far from mastering that theory. This is a diagramming app and the goal is to get a squiggly line between two objects. Thanks!

Re: [Interest] QGraphicsView selection not honoring QGraphicsItem::shape?

Cool, thanks for digging into it a little more. Thanks for the tip on stroking the path for shape(), though I already do that as demonstrated in qgraphicsitemc.cpp - I just removed it from the example code I posted here :) Here is a video of it still not working but with your debug code:

Re: [Interest] QGraphicsView selection not honoring QGraphicsItem::shape?

Thanks for the important tips, I wasn’t aware of any of them! I implemented all of them. Unfortunately it is still selecting based on boundingRect. Any other thoughts? > On Jun 25, 2017, at 5:00 PM, Christian Gagneraud <chg...@gmail.com> wrote: > > On 26 June 2017 at 05:10,

[Interest] black screen with iOS app over airplay?

Hello! Has anyone else had a problem with Qt apps only showing as a black screen when mirroring an iOS device over airplay? Other apps display fine, but then the AirPlay display turns black when the Qt app is brought to the front. Granted, I am using Reflector 2 to show the iPad screen on my

[Interest] Slow touch event sample rate after 10.3.1 iOS sdk

Has anyone else noticed that the sample rate for touch events has dropped to 800ms since the last iOS SDK update? I have tested with both Qt-5.8.0 and Qt-dev and it’s happening on my iPhone as well as iPad pro. I read somewhere that you have to update the view in order to get the sample rate

[Interest] speeding up "make clean" in qt src on OS X?

Hello! Running “make clean” in the root qt src dir calls xcodebuild a whole bunch of times and takes a really, really long time. Is there any faster way to do this? I am already excluding a lot of unnecessary builds in my configure line: ./configure -static -debug-and-release -nomake examples

[Interest] iOS: QPropertyAnimation on QWidget.pos not hardware accelerated?

Hi there! I have a simple QWidget with a single (empty) list view that I am trying to use for a fullscreen slide-in panel on iOS. The problem is that the animation of the ‘pos’ property doesn’t look hardware accelerated on iOS. It looks great on macOS, however. The slide-out widget is covering

[Interest] Prevent QGraphicsView calling fitInView() after addItem()

Hi there! It appears that the default behavior for QGraphicsView is to call fitInView() to center all the items in the scene when a new item is added. Is there a way to prevent this? I don’t see anything in the docs. Thanks! -P ___ Interest mailing
