@mj01 Up to you to use or not to use debugger to get more information about your issue, I'm out...

@mrjj Thank you for your tip. Its great help for a QT and C++ beginner. I'll try to implement the logic you mentioned.

I had checked the toolchain with my previous installation which is gone with the crash of my desktop. Therefore, I cannot check anymore. However, the toolchain for cross-compilation on my current installation is broken.

Great ! Happy hacking then :) Don't forget to mark the thread as solved using the "Topic Tools" button ;)

@IL said in Virtual Keyboard for embedd: Can you give me perspective about how hard it to move from QT5.5 to QT5.7? equal zero? :)

Replying to myself as I've found the solution. If other people face the same issue they may find this to be the fix. under /etc/environment I had the line: QWS_MOUSE_PROTO="Tslib:/dev/input/event1" However, this didn't seem to work. I'm not entirely sure why, I'll probably look into it. If, however, I use: export QWS_MOUSE_PROTO="Tslib:/dev/input/event1" , and then run the application, it functions correctly.

Sorry, I meant a more recent version of Qt Creator, as for Qt 4 the latest version is 4.8.7

Hi and welcome to devnet, Boot2Qt is a commercial offering, you should contact the Qt Company/Digia directly through e.g. the Support Center accessible on your Qt account.

Hi Pavlya, did you manage to get this working? I have the same problem. I'm using Beaglebone Black running Debian and have Ubuntu 14.04 on my desktop with QT 5.4.1 (x64)(Creator 3.3.1) I can connect from my Desktop using PUTTY or terminal without any problems. BUT I have problems from QT, when I try to Add a kit (Generic Linux Device) it locks when press OK to accept the IP Address and Username etc. This is when it tests the connection to the device. I have reinstalled, I have also tried from another laptop with the same Ubuntu and have the same problems. Any help appreciated. Thanks
