Testing the upgrade to Qt 5.12



  • @dobey said in Testing the upgrade to Qt 5.12:

    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.

    I would say yes, because it's the only way we can have any sort of guarantee for something reasonable across all form factors.

    I would say scaled rather than cropped if possible

    I think both PreserveAspectCrop and PreserveAspectFit will likely behave the same way with what I described, anyway, since the image will always be smaller than the window.

    Developer, we will have to work around the limitations. All is knowing how it works before hand.

    Right. We need a proper and accurate description of the behavior, for which we can judge against when any complaint is made about that behavior to determine if said complaint is a valid issue or not (ie, whether we need to fix it in Lomiri, or app dev needs to fix their image). I don't think the current description is accurate for what the code is doing, and if we modify the code to actually behave that way, it will not give the desired effect in most cases. Though, if we want the existing description to stand, I can certainly make it work that way.

    Vertical splash images from Sailfish or Seedsheep look ok only on portrait, true. Square it is then

    Though, if we want the existing description to stand, I can certainly make it work that way.

    The only thing I can think of is: scale down the splash image to the size of the screen but when scaling up, maximum to the size of the image.
    Say, fit a 512x512 image in smaller screen but show the corresponding image size in tablet (without scaling it up)

    The idea would be showing a relatively same image across devices.



  • @CiberSheep OK. So, in the current build I have changed the code to accurately behave according to the existing description. In this way there is no scaling, and the image is centered.

    Please try it with many apps and let me know what you think.



  • A bit less important but I'll report anyway and with the upcoming Volla and Fxtec, this might be more noticeable to users 🙂

    The icons in the indicator gets squished in the external display with the exemption of some.

    And going back to the device screen expands them. I think I've encountered this issue before from to time to time though so this isn't exactly new but with Qt5.12, it seems that it always happen.

  • @dobey Ok, finally found time to run some tests.

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

    It is from logviewer.

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

    Great! 👍

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

    Ok, whenever I try to start an app via terminal app with bash runclick.sh com.ubuntu.clock, I do get the same error:

    aa-exec_ ERROR: profile 'com.ubuntu.clock_clock_3.12.5' does not exist



  • Just my findings, may they help others:

    Running Rodneys script from terminal app from within the phone does not seem to work. But using adb shell works great!

    If you need to find the proper names of the apps to run them, use click list (thanks Rodney for this hint). Copy/paste possible in adb shell for even more convenience. 😉

    Updated and testing.

    • I think it works good for staged splash
    • With side staged or windowed, not so. Is it possible to scale down to fit the window size on those cases (when splash image is bigger than the window)?

  • Hm. When changing from one view to another in calendar app, the first time I enter a view, the header gets messed up. After switching back and entering a second time, things look fine.

    Just me? (Testing a few other things, so might be.)

    The only entry in log (Logviewer) that seems to be new is this:

    file:///opt/click.ubuntu.com/com.ubuntu.calendar/0.8.4.2/qml/EventListModel.qml:183: TypeError: Value is undefined and could not be converted to an object
    file:///opt/click.ubuntu.com/com.ubuntu.calendar/0.8.4.2/qml/DayView.qml:94: TypeError: Cannot call method 'scrollToTime' of null
    


  • @danfro this might be a state that has no default or the when condition is checked before the boolean is ready

    Nope, but I haven't found anything in logs that would point to the cause, other than the fact that Tabs is deprecated.



  • In notes app, when opening a note and going back to notes list, the header disappears. I think notes and calendar need to be stripped of the deprecated components to work properly with Qt 5.12.

    Header of notes app is the bad boy I suppose. Tabs the bad boy for calendar.
