Where do I find the GTK widget properties?

General Usage
1

Hi
I started using Julia to build a form generator by GTK and I haven’t find a list of widget properties so, for example, for set the button width. I have tried this:

function createButton(caption,width)
        btn = GtkButton(caption)
        set_gtk_property!(btn, :width,width)
        return btn
end
...
ok = createButton("Ok",70)

obtaining this warnig:

g_object_set_is_valid_property: object class 'GtkButton' has no property named 'width'

Thanks

Unfortunately, the documentation is very sparse. I scoured the unit tests and source code, and also cross referenced the GTK documentation here.

I hadn’t seen this documentation yet.
On first examination it would seem (perhaps) that the solution is CSS. I try to investigate this.

Hello
I was able to set some button properties (text color, border), but not width:

function createButton(name,caption,width)
        btn = GtkButton(caption)
        sc = GAccessor.style_context(btn)
        pr = CssProviderLeaf(data="#$name {background:olive;border-width:10px}")
        push!(sc, StyleProvider(pr), 600)
        set_gtk_property!(btn, :name, caption)
        return btn

set_gtk_property!(b, :width_request, 1000) is probably what your are looking for. The widgit properties are all printed when a widget is displayed as text at the REPL. This is a REPL session where I found it:
