Using multiple channels for events

[André Moraes]

Just an proposition, but maybe instead of a single channel for events, why not use one channel for each kind of event.

So, instead of wd.Window having a single EventChan() method, it had:

MouseEvents()

KeybordEvents()

SystemEvents()

The first problem that I see is how to handle a mouse move simultaneous to a Keyboard keydown, currenctly on most systems those events are pushed into a queue and handled one at time.

The thing you suggest is straight forward to implement on your own. go.wde is meant to be the absolute barest possible bones. More interesting layers like what you talk about can be built on top.

But it's an intresting idea? I was more asking for comments about that than requesting that to go into go.uik :)

Gotcha.

It's actually something I experimented with in the early (or earlier, anyway) stages of uik. I felt it made the internal API too difficult to work with - having a single channel that you type switch off instead of many channels that you select{} on makes it easier to forward the event to, for instance, an embedded type. Like, a widget will forward an event to Block.HandleEvent() in the default case. With select, there is a lot more overhead, both typing and runtime.

Moving back to the single-channel/switch{} strategy simplified a lot of code.
