Testing the upgrade to Qt 5.12

[CiberSheep]

Edit, thanks @jezek I confirmed, it's an error of syntax:
pushing a page created in js, to a PageStack doesn't work in Qt 5.12 if properties are added:

var importPage = mainStack.push(Qt.resolvedUrl("PageHubImport.qml", {"allowMultipleFiles":false}));

Edit: parameters,should be outside of resolvedUrl

var importPage = mainStack.push(Qt.resolvedUrl("PageHubImport.qml"), {"allowMultipleFiles":false});

Interesting:

var importPage = mainStack.push(Qt.resolvedUrl("PageHubImport.qml", {"allowMultipleFiles":false}));

I think, the parentheses are mismatched. I should be:

var importPage = mainStack.push(Qt.resolvedUrl("PageHubImport.qml"), {"allowMultipleFiles":false});

Testing on M10HD.

• Calendar crashes after some secods to be opened (same in E5): https://paste.ubuntu.com/p/d5WXvnFb4h/
  Fixed

• GearSystem works

• Splash screens are a bit too big. Special issue with side stage (don't look at the background color)
  Fixed

I'm not quite sure what's going on in this picture. What's the giant white bar across the screen, and why is OpenStore not filled to the bottom?

There is an issue with splash image in quickddit too, but there is too small. And clock app crashes only when there is any alarm.

[dobey]

OK. I've made another change to the splash image handling that should hopefully fix these last issues. If you could update and test again to verify, that would be great, thanks!

Tried to track this down, and was able to get a crash, but after rebuilding a couple repos so I could get debug symbol packages from CI, it now just works. So please update and see if it still occurs. Thanks.

Crashes in both Clock and Calendar apps has been fixed :party_popper:
Splash image in gallery app is weird, but it can be fixed with new higher resolution icon.
Issue with not remembering settings across app (Morph, Podbird, etc) restarts still persist for me, phone goes to sleep during video playback too. No any other issues for me

Looks like we're slowly getting there, congratulations to everyone involved with a special thanks to @dobey

It's fixed with the latest changes

Some apps with custom splash image are too stretched out like for example Gallery.
It's also the same as Talaan and the common thing with them is that the custom splash images are both png instead of SVG. My guess is that the current behavior is that the size is based on the image size but with qt5.12, it's always stretched vertically or horizontally.

[dobey]

@kugiigi The problem is that Image {} can't magically determine the intent of app devs showing splash screen, and some define it incorrectly. There's an updated splash in gallery-app on GitLab but it hasn't been released yet. But even these new splashes will have some problems in certain situations, and won't work for all possible window sizes under Lomiri. It just happens that apparently some changes in Qt 5.12 are exposing these issues to us.

So, we need to define the expected behavior for X-Ubuntu-Splash-Image better, and stick to that, and then if there are still more complaints about size or scaling, the apps need to be fixed. So, what is the opinion of @CiberSheep and UX group here?

The old Ubuntu platform guide says this on it:

File name of an image present in the directory stated in the Path entry. The splash image is centered on the splash screen and displayed in its actual size (ie, it's not stretched or shrunk and aspect ratio is kept).

For vector images, the splash screen has always scaled the image to fill the minimum value between window width and height. Not sure if we want to change that or keep it...

[dobey]

OK. Did a little more poking at the Splash, and I think I have it working more like it was before, without the weird artifacts happening. Please upgrade and test again. Thanks!

[dobey]

Well, that didn't seem to really fix everything, and with more poking about at the X-Ubuntu-Splash-Image handling I'm surprised it every worked as described in the platform guide. I can't seem to get a configuration of the Image {} component which provides the behavior described there, and which also provides a usable experience with the sample set of apps installed on my test device, nor in my VM running unity8 on 16.04.

Just pulled the latest devel update for my E5, devel.

Calendar app does crash on startup. http://paste.ubuntu.com/p/F4WjzkkQh9/

Notes app does open, but too only gives blank screen when opening a date picker. http://paste.ubuntu.com/p/XYrxkX2PNd/

FluffyChat works, also bottom edge. Although when opeing that the first time it took a few seconds to open up.

Teleports + dekko blank screen on startup.

uTorch does crash after it has lost focus.

Farkle, sprint app, ThemeSwitch, Logviewer, terminal, music app, gallery app, weather app, docviewer, file manager, calculator are working (basic functions).

Ok, thats for a first feedback.

I think this is a good way of going. On Qt 5.9 the image is scaled to the smallest size but that works kind of funny on the tablet.

If that's possible to implement, we can add that to the HIG and change any app that need fixing afterwards.

Is the pastebin from the log file, or from using the run-click.sh script I posted above to run it from CLI?

Notes app does open, but too only gives blank screen when opening a date picker.

I've opened a PR against notes app to fix this now.

uTorch does crash after it has lost focus.

It seems to work OK here on my e4.5. Can you run it using the script I posted above to see what happens?

[dobey]

@CiberSheep I don't think it can be implemented as described, and give a good result. IIRC, the idea was for it to allow people to provide a phone-sized image, but that clearly doesn't translate to tablets or PCs.

I can implement it such that there is a maximum square area that matches the smallest edge, and we can have the image scaled/cropped for that area, but there will still be situations where the result it gives us will not be what app devs desire for their splash images.

• It has to be a square, then?
• I would say scaled rather than cropped if possible
• Developer, we will have to work around the limitations. All is knowing how it works before hand.
