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

Changing in response to freetype-go changing their scaling of stuff. They switched up the scaling factors, so now you need to get FUnitsPerEm() and send that to font.Bounds() and use that where you would before have used UnitsPerEm(). Seems a bit silly. Still, fixed.

Hi

I wrote a little hello world tutorial to help people getting started with go.uik. Are you interessted in more tutorials (e.g. labels and buttons)?

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

Am I missing something?

Looking at go.wde/init it seems the examples in go.uik/examples possibly set a bad example.

If there's a reason it's done this way in go.uik, I'm all ears by the way. I don't mind being wrong ;-)

2 problems with backspace on OSX on an entry field:

• Pressing backspace on an entry inserted a character; KeyTypedEvent.Glyph contains a character on backspace.
• Once the previous problem was fixed: Focusing on an entry by clicking sets the selecting field to true, which caused problems with the range calculation on backspace and delete.

(This is my first time contributing to an open-source project, so please be gentle :smile:)

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.

go get github.com/skelterjohn/go.uik go/src/pkg/github.com/skelterjohn/go.uik/fonts.go:34: not enough arguments in call to font.Bounds go/src/pkg/github.com/skelterjohn/go.uik/fonts.go:35: font.UnitsPerEm undefined (type *truetype.Font has no field or method UnitsPerEm)

This fix is needed to get it to compile, but I haven't yet successfully used the package, so I'm not sure if I used the "scale" parameter right.

John,

I've got cut, copy, and paste fully working for the entry widget. Don't forget to pull in my changes on go.wde. This won't work without them.

Also, I fixed a minor issue where any selected text in the entry widget would drop it's selection when only a modifier key is pressed. :)
