问题 Do you change the key binding in the OS to be, i.e., Ctrl-Q? Do you manage to stretch your left hand to the C key? Do you use right ctrl and press shortcuts with your right hand? 回答1: When I switched to Dvorak, I was using primarily Ctrl + Ins and Shift + Ins for copy/paste. Now I use Ctrl + C and Ctrl + V and other program-specific shortcuts, but I have just learned to use them in their "weird" locations. A similar question was asked on SuperUser, with the following answers: Use an

问题 The struct SDL_Keysym has SDL_Scancode and SDL_Keycode members. What is the difference between them? The documentation does not really clear it up for me. I tried both and they seem to do the same thing. 回答1: See the SDL documentation.

On an AZERTY keyboard, pressing A will emit a 'Q' scancode and an 'a' keycode. 回答2: Generally,

I am not starting from zero in programming; I just have no idea on where to start to make a system level device like a virtual keyboard.

问题 In Qt, how can I ignore all mouse and keyboard events and later stop ignoring them? That is: click a button, ignore all events in children; click again, not ignore. Is that clear? I have the following lines, but maybe I'm doing something wrong: setAttribute(Qt::WA_TransparentForMouseEvents); setFocusPolicy(Qt::NoFocus); 回答1: Dont use setFocusPolicy(Qt::NoFocus); and it will propagate events to the parent. Use only setAttribute(Qt::WA_TransparentForMouseEvents); 回答2: You can use Events'

问题 Is there any known combinations of inputTypes on an inputText that would give a Num-pad keyboard with special characters such as $ , * , # and & . I am trying to allow the user to input a number and that field could take the mentioned characters as well. I have tried many but none seem to be giving the required output. Would I have to create my own custom keyboard for this? Since my request is very specific to certain special characters please do not mark this as a duplicate question. Thanks
