qvirtualkeyboard for linuxfb embedded linux device

[gkris]

Hi,
I am trying to implement virtual keyboard using qt.
I came across this documentation

https://doc.qt.io/archives/qt-5.11/qtvirtualkeyboard-index.html

But I have the following constraints:

1. The target embedded linux device I use supports only linuxfb.
2. The device supports qt 5.11 only
3. I want to integrate virtual keyboard in a QWidget application

How to go about building virtual keyboard for this setting? Any suggestions will be appreciated.

Hi and welcome to devnet,

If you do not have any OpenGL available, you should check if your version of Qt supports the software rendering.
