Oh, sry i missread the diff. But it's ok in both ways :)

I would never do that. A part that locate is the weirdest program i have ever seen in unix...such a crappy file indexer. And rm -rf can result on a really desperating situation..and leastly using sudo..which is a really bloated app.. Really. Those two lines make my day.

I cant find swk useful in any game. Only as simplistic frontend for many apps to interact on touchscreens and small devices, and probably on desktop boxes takes some sense to enable my mother to do some basic things..also a mail client, web browser, image viewer... But never in a game..games NEED fancy graphics, and this is not what i try to do.

Why you need to encapsulate such simplicity? Can you remove those imposed requeriments from your mind?

This will be added, and its not that complex (maybe 15LOC) just dont blame me to publish a POC. Because i already put that in todo.

Same as above

Same as above

i never said that

Why do you need that?

This is already supported

Point this understand dont I.

Did you read config.h?

This is about the backend..can you explain less on this?

This will be optional in config.h. Maybe i should buy new glasses, but i still fins this feature useul.

You are free to send pull request.

Means 'it is supported'. So..you can use swk on a touchscreen without having to mess with invalid input events. This doesnt means multitouch or anything else. It just means touchscreen.

Swk_box_newline(-1) // its a macro.

This isnt clear, because isnt defined at all, feel free to propose a better design/name for it.

The thing is that positive newlines are just that, and negative ones open a scrolling area.

Neither of them. Its a TODO.

Yep. User interfaces requires a long list of design guidelines. And we should define new rules for suckmore UI apps.

I agree with all those points, but which points do you think swk doesnt follow?
