Mobile and Embedded

@jsulm ,

Got it,
I will check it first
Very Appreciate your help

This is not legal advice. But I can tell you an anecdotal story from my previous company I worked for.

The company produced heavy duty machines that could, for a better user experience, be equipped with a of the shelf android tablet and a custom app made in Qt.

We used to own a normal commercial licence there and developed that app with that licence. After some years during a renewal process, the QtC decided that this was an embedded device since the tablet was sold/shipped with the app preinstalled and would like money for each sold unit.

The end of the story is, the mechanic setting the machine up now has to do the extra step of connecting the tablet to the internet, getting the app from the Appstore and than placing it back into the machine.

Oh, and the company startet to transition away from Qt.

It compiles for me, too, but it doesn’t run.

do_install:append() = " mygui" is the correct syntax.

@Juan-Gomez If your board only has Qt5 then use Qt5 to build your app.
You can't mix Qt5 and Qt6.

Known issue in the Qt bug tracker:
https://bugreports.qt.io/browse/QTBUG-130813?filter=-4&jql=text ~ "ios ffmpeg" order by created DESC
and
https://bugreports.qt.io/browse/QTBUG-129533

I decided to move on with the build image following the st instructions, which seem to be a little more documented.

Change android: lunchMode ="single instance" did the trick

@MicHes said in QT Widgets not responding to touch event sometimes:

Hi @JoeCFD,
speed is not the main issue here - I meant that code you need to change every time you add or remove a button would not be maintainable. There would need to be an routine that automatically finds the button (if any) a touch event belongs to, otherwise it will cause more problems down the line.

Greetings, Michael.

or use static cast for find button name and apply code for that when find it.

seems to be related to;

@StudentScripter No, I haven't. But I think it must be possible to improve the performance. If you try the Qt positioning examples that use the QtQuick Map element the responsiveness to drag gestures is good. The Qt documentation states that Map uses OpenGL (ES) but I have not found a way to match the responsiveness of QtQuick Map even using OpenGL.

However, I find that a QGraphicsView with a QOpenGLWidget viewport performs really well on mobile platforms, even though some people in this forum claim that you can't use QWidgets on them.

Second part of the post. I was unable to post all at once.

Data that may be considered relevant:

Window flags configuration: flags: Qt.FramelessWindowHint | Qt.Window // If Qt.Window is not present, drag is not allowed (In Windows 10 at least)

Touch works well in raspberry. I can drag and drop without any problem.

Also multitouch works well outside the app

Seems related with QXcbDrag Github dev but i didnt find any related bug.

After the first touch event, when the next touch event is performed, the drag and drop works as it should BUT the swaped element is the one that had the root.held = true not the new i dragged.
