I want to use a color Chooser dialog in my app – https://github.com/satya164/gtk-theme-config
I cannot find any documentation about a ColorChooserDialog in vala. Currently I’m using color button to choose color. But I get following deprecation warnings while compiling, I’m using Vala 0.16.1 and GTK3.6 (The warnings don’t show up in GTK3.4). I cannot find a sample on using ColorChooser dialog. If anyone can help me implement the ColorChooserDialog, I’ll be really grateful.
valac --pkg gtk+-3.0 -X -lm gtk-theme-config.vala -o gtk-theme-config

Upgrade your Vala to the latest 0.17.x release (or ignore the warnings for now–they’re not doing any harm).
