I have same problem and I suppose that is related with Dropbox service that I use for backup my project few days ago I switch off auto sync for Dropbox and looks like it helps (need more time for guarantee) perhaps you have similar problem with some process that lock files

Just as @J-Hilk said: You create a class that derives from QWidget and then override its paintEvent method. Have a look at the documentation of Qt how to do your own painting in paintEvent. Most likely you need a member variable inside your custom class that knows the current percentage which could then be used during painting.

In the past I've used the i2c and spi hardware on a raspberry pi. The Qt framework hasn't got this type of implementation because it is related to each particular device. For the rasperry pi there are at lmany libraries to do this and I think there is someting similar for imx6. Normally the i2c / spi / gpio libraries are provide from the hardware vendor.

Hi, which hardware platform do you have?

Hi, IIRC (it's been a long time), you can use the QMAKE_BUNDLE_DATA variable to copy additional items to the app bundle. Hope it helps

The Qt developers (or at least one of them) say "We don't use it and never did".

@jsulm thanks !!

@KH-219Design said in Using Qt based shared library with the Android NDK: ion for And Thanks for your answer. Yes, compile the shared library and link statically Qt could be the solution. I'll give it a try. The only thing that worries me is any licensing issues. I'll mark this thread as solved.

Hi, Using what for scrolling ? Widgets ? QtQuick ? Mouse ? Finger ?

Here I described what worked for me in hopes that nobody else ever needs to go through all the stuff I went through before coming up with a solution: https://stackoverflow.com/questions/65263280/qt-android-unable-to-debug-error-unable-to-find-dynamic-linker-breakpoint-fun/65275623#65275623

I have fixed it after a period of debugging . but it's not likely going to appear every time . Or if you install your environment the first time , the phenomenon will not appear . i fix it just add by the fellowing approach : QT += core gui multimedia multimediawidgets

@jsulm yes i have follow your steps 2 times the it get solved. Thanks

Hi and welcome to devnet, One thing you can do is try to build the module yourself. Another one would be to update Qt to an actual version like the latest LTS which is 5.15
