Need Help: QTouchEvent Works but Qt Widgets UI Buttons Not Responding on Resistive Touch (TSC2007, Qt 5.12.12)

Hi and welcome to the Qt Forum, touch handling has been refactored in Qt 6, and 5.12 has been EOL for a long time. Please upgrade to a newer Qt Version, preferably >= 6.5.

Help Needed: Resistive Touchscreen Support with Qt 5.12 on Allwinner A133 (Linux 4.9 / Ubuntu 18.04)

Hello Qt Community,

I’m currently working on an embedded project using the Allwinner A133 processor with the following setup:

OS: Ubuntu 18.04
Kernel: Linux 4.9
Qt Version: Qt 5.12.12 (Qt Widgets)
Touch Type: Resistive touchscreen

I’m looking for guidance on resistive touch controller ICs and their integration with Qt. Specifically:

Any recommended resistive touch ICs with stable Linux driver support
Experiences using Qt Widgets with resistive touchscreens (evdev / tslib / Qt input plugins)
Known issues, patches, or configuration tips for this kernel + Qt version

If anyone has already worked on a similar setup or can share best practices, sample configurations, or IC recommendations, your help would be greatly appreciated.

Thanks in advance for your support.

Regards,
Thirugnanasampantham
