Mobile and Embedded

Hi

I think you have to uninstall everything and reinstall the free version of maintenance tool, and thus everything else behind (creator, design studio, Qt versions etc etc ...), and unless you request Qt to transfer your account to a free account and wait for them to respond, you will have to create a new account.

@kuroro-l First, your code has nothing to do with Qt. When you build it for Android, you need to pack gstreamer build(libs and plugins) for Android with your app.

If you want to use Qt sink in your pipeline, try to make a Qt GUI and use qml or widget sink in your pipeline. There are quite some posts about how to do it in this forum and gstreamer forum.

The original MInGw compiler has not found this problem, because of code reasons to change to the MSVC compiler, this problem occurs frequently.This problem is not frequent.

Thanks, this is great. While I agree that there is no one-size-fits-all, especially considering how much people want in the baseline (ci-cd, gui tests, etc), it still looks to me like the strength of Qt could be captured better - perhaps with more than one template.

I will see if emericg has some bandwidth. Perhaps we can fund one that everyone can just pick up.

I had a similar situation. I needed to control 4 sliders at the same time. I created a slider in a qml file. I added that qml file to the interface with 4 separate QQuickWidgets and I had 4 simultaneously controllable sliders.
Cpp Ui adapt touch event to mouse event. Due to mouse behaviour, you cant click or slide two object at the same time. :D

You should take a look : https://github.com/aaronsnoswell/QMLVirtualJoystick/tree/master

I created a bug report for this case.

Hi,

GitHub is only a mirror of Qt's sources so what exactly did you install ?
As for your project are you using something like cmake to manage your project ?

Hi,

From memory, some of the dependencies that used to be vendored were taken out in 5.15. It might be such a case. You should check the test results to see exactly what made them fail.

Hi Jason, We are too facing similar keyboard integration error for embedded linux. In this case did you rebuild the whole QT source code of v5.11 OR just QtQuickControl2 module only?

@JKSH Thank you,

In fact, on this aarch-linux mechine, qtvirtualkeyboard works well on Konsole, I don't know how Konsole did it.

I even tried Pyside2 5.12.5 and it didn't help.

I just install qt5, and tried a QTextEdit case under Qt/C++, qtvirtualboard works well.

Aren't C++ and pyside calling the same underlying library?

As I already said, QtWidgets has never been intended to work with mobile devices. So knowing the history of Qt, knowing why QtQuick has been created ... I wouldn't expect this bug to be addressed.

Not solved in 6.8 :(
