@prinzkm I don't have any experience with Qt on embedded devices. However, on the same page you provided the screenshot it has a section on "Available Keyboard Drivers". These are Qt-specific drivers, as far as I understand. It seems that currently only two drivers are available: TTY and LinuxInput. By default Qt is only compiled with support for TTY. Unfortunately, this is also the driver which intercepts Ctrl+Alt+F1 and Ctrl+Alt+Backspace. Therefore, you should have a look at the other driver. My understanding is that for this to work you need to compile Qt yourself with the LinuxInput driver enabled (by providing the command line option -qt-kbd-linuxinput when configuring Qt before compilation. I hope, somebody else can help you with these keyboard drivers.

Hi, Why not generate key press events matching the correct key when getting your network packets ?

@JEllery Thanks so much for solving this. It seems to solve my deletion-crash issue as well. :)

I think you need to explicitly accept the event to trigger the override, as mentioned in the QKeyEvent doc. Call "event->accept()" before "return true" may resolve your problem.

@sogo No you don't. eventFilter has two parameters so you can use the object parameter to ensure you apply your filter only on the widgets you want to and not on the others.

That worked fine, thanx a lot for your help

@etiennedm Why don't you just use layouts?

@p3c0 Yeah, i realized i forgot that. Thank you.

Hi, What you do is to send your event to the event dispatcher for it to dispatch said event to the correct object but at the same time you're setting your filter between the dispatcher and the rest of your application. Thus you are seeing the "impossible" Hope it helps

Hi, thanks for your reply. I have been unable to test it for time reasons and this horror will still be going on for months, keeping me from working at this project. I think it's best to bookmark this page and eventually return to it when times are better. Have a nice week-end, Kalsan

@p3c0 Where exactly i should put that code? As I asked earlier how should i know which button is pressed ?If you see my code I did with a signal but in that case i would need so many signals which is not a smart way to do. I am thinking of Bit masking .For example (sudo code) OnClicked(Object sender) { if(sender == "BIT1") { BYTE1 |= 0x01; // AND operation BYTE2 &= 0xFE; // OR operation } But don't know how to get that object and implement in qml.

I found solution. i remplemented keyPressEvent from QTextEdit class void MyTextEdit::keyPressEvent(QKeyEvent *e) { if(e->key() == 16777220){ //enter clicked return; } return QTextEdit::keyPressEvent(e); }

@p3c0 You can upvote answer if you find it useful ;)

@SGaist I got it. Thanks for the reply. Cheers
