我想在我的应用中使用颜色选择器对话框 - https://github.com/satya164/gtk-theme-config
我在vala中找不到任何有关ColorChooserDialog的文档。目前我正在使用颜色按钮来选择颜色。但是我在编译时得到了以下弃用警告，我正在使用Vala 0.16.1和GTK3.6（警告不会出现在GTK3.4中）。我在使用ColorChooser对话框时找不到示例。如果有人可以帮我实现ColorChooserDialog，我将非常感激。
valac --pkg gtk+-3.0 -X -lm gtk-theme-config.vala -o gtk-theme-config

答案 0 :(得分：2)
将您的Vala升级到最新的0.17.x版本（或暂时忽略警告 - 它们没有造成任何伤害）。
