go.uik's Introduction

This project is closed. If I begin again, it will be from scratch and using lessons learned while writing go.uik. Of course, if I begin again it will still be called go.uik.

#go.uik

A concurrent UI kit written in pure go.

This project is in its infancy. Feel free to experiment, but don't expect too much yet.

There is a google group dedicated to this project.

###A concurrent UI kit

Every component visible on the screen is backed by a Block. Every collection of components is backed by a Foundation. All Blocks are built upon a Foundation, but a Foundation itself is made up of a Block, which must itself be laid upon a Foundation. The only exception to this rule is the WindowFoundation.

All communication between Foundations, Blocks and the widgets and layouts composed of them is done via non-blocking channel communication.

While this is a break from the typical polymorphism approach, the result is that a component that stalls while processing input cannot get in the way of other components.

I copy/pasted your widget tutorial code, built it, and tried to run it.

Am I missing something?

xgb backend problem

I'm currently migrating an application I'm working on from go-ui to go.uik

I discovered an issue while building on Linux, and the fixes are simple (incorrect and missing casts)

I got the following errors when trying to build:

../../github.com/skelterjohn/go.wde/xgb/icon.go:57: cannot use width (type int) as type uint in field value
../../github.com/skelterjohn/go.wde/xgb/icon.go:58: cannot use height (type int) as type uint in field value
../../github.com/skelterjohn/go.wde/xgb/icon.go:59: cannot use data (type []int) as type []uint in field value

so I changed the function SetIcon like so:

func (w *Window) SetIcon(icon image.Image) {
    width := icon.Bounds().Max.X - icon.Bounds().Min.X
    height := icon.Bounds().Max.Y - icon.Bounds().Min.Y
    data := make([]uint, width*height)
    for x := 0; x < width; x++ {
        for y := 0; y < height; y++ {
            i := x + y*width
            c := icon.At(x, y)
            r, g, b, a := c.RGBA()
            data[i] = uint(a + r<<8 + g<<16 + b<<24)
        }
    }
    wmicon := ewmh.WmIcon{
        Width:  uint(width),
        Height: uint(height),
        Data:   data,
    }
    ewmh.WmIconSet(w.xu, w.win.Id, []ewmh.WmIcon{wmicon})
}

and it now builds and runs properly.

compiling on windows

I tried to build the uikradio on windows 7 64 bit using 64bit go (tip):
