Releases for Linux? #46

Hi, thanks for trying it out. Sorry that it didn't build for you. As Qt Quick Controls 2 is fairly new and new features and fixes are coming in all the time, I need to use the latest version to take advantage of them. I've briefly looked into binaries for Linux (e.g. flatpak) but didn't get very far with it. I have an Ubuntu machine that I can build binaries on, so I could just try to do it the simplest way and zip up the binaries. |
|
That would work for me, thank you! |
I just tried building pickawinner with a pre-built Qt 5.10.0 on Mac and it worked fine, so I'm not sure that the issue is there. |
|
I got very close to a working release build, but ran into a bug which I think is an issue in Qt: |
|
Just wanted to say this looks really awesome. I would really appreciate a Linux build as well. :) |
Thanks! I'll try to look into the release build issue to see if I can get this moving again. |
|
That was a wild ride. I ended up building statically. The bug seems to be here: Here's a Linux (Ubuntu) build - I hope it works for you! :) https://github.com/mitchcurtis/slate/releases/tag/v0.0.12 |
|
Thanks! I'll try it out tomorrow. |
|
Thank you very much! It seems to be working at a first glance, I will give it some more testing. One thing I noticed so far is that when the cross or box cursor is displayed, the movement of it has a perceptible lag, which is a bit annoying when drawing. That doesn't happen when a hand cursor is displayed (inside a selection), so I suspect it's something about the custom cursor shape. |
|
There is also no menu bar being displayed — I noticed there is a menu bar in the Windows screenshots. Should I be reporting those as separate issues? |
Could you please create a bug report for this (along with a video or GIF of it in action if you don't mind)? I haven't noticed any slowness, but I can imagine that it's indeed due to it being a custom Item cursor instead of a system cursor.
Which OS are you on, and what kind of menu bar does it use? It's probably #41, which links to the bug in Qt: |
|
I have reported the cursor lag under #52, but I am at a loss about how I could record this on a video — the lag is between the mouse movement and cursor movement, so I would need to somehow record both in sync? And the lag is small — felt rather than seen — so I have no idea what framerate I would need to have to make it visible on video. As for the menu bar, I'm testing it on Xubuntu 17.10 without any special "kind" of menu bar — just the normal GTK/QT menu bars that you can usually see near the top of the windows. The Slate window misses it. |
No worries, that's fine. :)
Hmm, I dunno what kind of menus they are, but it sounds like you're saying they're Windows-style menus; integrated with the window itself as opposed to the Unity/macOS style "global" menu bar that sits at the top of the desktop? |
|
Yes, they are integrated with the application window. |
|
Hmmm, damn. I've added it here: |

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.

Hi, I wanted to try this editor, but I couldn't find any released binaries for Linux. I decided to try and build it myself, so I went looking for QT 5.11 — turns out it's not released yet. Then I tried to build the beta release of it, and it doesn't build on Linux due to ^M characters in all the configure scripts. At this point I simply gave up.
Any chance for Linux binaries to be included in the releases?
