@J-Hilk said in How to get ALL the keyboard pressed keys WITHOUT RESTRICTION OR FILTER?: Inside main.cpp install an eventfilter on the Q(GUI)Application Thank you very much, this was exactly what I needed!

Well, it's not something that's provided by Qt out of the box, so you'll have to check the platforms you want to support for how they provide that information. You could even consider contributing that to Qt to improve it for everybody. You might also open a feature request on the bug report system for that.

@VRonin said in Send arrow keys via QProcess in any platform: @Mark81 Then do you really need Qt? there are already mature tools to do those kind of things, for windows: http://ahkscript.org/ and for linux: http://www.semicomplete.com/projects/xdotool/ I don't need Qt for this. But I have a quite large application that does a lot of things. One of those, is to launch external applications and send them keystrokes as you would type in front of a keyboard.

Here's the solution. You have to do it in Javascript. Ensure jQuery is loaded in your web pages (even the IFRAME/FRAME ones) and then apply this code: <script type="text/javascript"> $(document).ready(function(){ // Disable backspace key except in fields. $(document).keydown(function(e) { var elid = $(document.activeElement).is('INPUT, TEXTAREA') ; if (e.keyCode === 8 && !elid) { if(e.ctrlKey) { window.history.back(); } else { // disable backspace e.preventDefault(); return false; } } }); }); </script> SOURCE: http://stackoverflow.com/a/17278620/105539

So you already tested the Edit->Advanced possibilities ?
