Since GdkColor isn't derived from Boxed, getBoxed will return null.
Try getPointer witch should return the GdkColor*.

I've got assertion error when tried to use it: GLib-GObject-CRITICAL **: g_value_get_pointer: assertion G_VALUE_HOLDS_POINTER (value)' failed`
Using getPointer() assumes that GValue holds gpointer, but AFAIK, in my case it must hold GdkColor wrapped by Boxed.

Yes, you're right the GdkColor is a boxed value, i don't know why it's returning null though.

Solved this way:

RGBA even = new RGBA();
RGBA odd = new RGBA();
StyleContext context = m_uiTreeView.getStyleContext();

context.save();
    context.addClass(GTK_STYLE_CLASS_VIEW);
    context.save();
        context.addRegion(GTK_STYLE_REGION_ROW, GtkRegionFlags.ODD);
        context.getBackgroundColor(GtkStateFlags.NORMAL, odd);
    context.restore();

    context.addRegion(GTK_STYLE_REGION_ROW, GtkRegionFlags.EVEN);
    context.getBackgroundColor(GtkStateFlags.NORMAL, even);
context.restore();

Still dont know why getStyleProperty returns null (I also tried gtk_style_context_get_style C function, which gives null too). Thanks for replies.
