set top box UI with qt

[Alex_wang]

hi,

I use qt to design the set top box UI，and a remote tv controller can control the UI with the key "Up", "Down","Left","Right" .
The UI has received the key information from the remote tv controller,
but how to Switch the UI interface with the key information like that the UI responses the keyboard

It purely looks like specific implementation.

Your architecture should talk about this.

For example, When you press right arrow, say you want to change the channel

switch(key)
{
    case Right:
    {
        funcShowNextChannel();
    }
    break;
    case Left:
    {
        funcShowPrevChannel();
    }
    default:
    break;
}

Something like this may help you.
