Thanks for the feedback. :)
Did you build with Creator or from the command line? There are instructions for both here, and they should just work (i.e. without building submodules manually). What was the specific issue you ran into?
Ah, sorry about that. I think it's time that I started using branches instead of putting all my unstable stuff into master, since that's the branch you get by default when you clone. This is now fixed in master.
Can you please post the failure messages? The tests were passing for me last time I checked.
I haven't tested it on Fedora, only Ubuntu. Which desktop environment/manager/whatever it's called does that use by default? Or which one are you using?
This uses Qt Labs Platform. The docs say:
So it could be that I'll have to go back to using a non-native menu bar on some platforms. How I'm going to detect that at build time.. no idea.
I'm guessing you mean that it's too slow? I changed it a while back to improve it on the MacBook touchpad, but then it started being crappy with a mouse. I need to find a sweet spot. I've created #40 to track this.
This one has been around for a while. It's indeed not nice, but I also don't consider it a huge priority for Slate, as it's meant for doing up-close, pixel-by-pixel stuff, not sketches. I've created #39 to track this. |

I tried to build from QtCreator and then using qmake. Both complain about missing unit. |
I've been thinking about this a bit, and I don't really see the point in this. If I make Since it's mostly just me working on this, and there are packaged releases and tags available, I'm going to document that these should be used instead. With regards to the build issue, I can't do much without the actual failure messages, unfortunately. Feel free to open a separate issue for it. :) |

The full backtrace is below.
My understanding is that this line in TestHelper::addNewGuides
VERIFY(imageGrabber.requestImage(canvas));
results in QQuickItem::grabToImage connecting to this signal:
connect(window(), &QQuickWindow::afterRendering, result, &QQuickItemGrabResult::render, Qt::DirectConnection);
We then wait until the image is not null:
TRY_VERIFY(imageGrabber.isReady());
This is important, as we should really be listening to the ready signal.
Meanwhile, on the render thread, the image is set at some point:
d->image = d->texture->toImage();
I'm guessing that, back in the main thread, we then detect that the image is not null,
store it, and destroy the QQuickItemGrabResult:
const QImage originalCanvasGrab = imageGrabber.takeImage();
QQuickItemGrabResult::render() is still running though, so it tries to delete the texture
and set it to null:
delete d->texture;
d->texture = nullptr;
The latter causes the HUAF.
Fix it by listening to the ready signal, which is emitted via a posted event,
so we can be sure that it's safe to destroy the QQuickItemGrabResult.
