我想在我的应用程序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。但是我在编译时收到了以下弃用警告，我使用的是 Vala 0.16.1 和 GTK3.6（警告不会出现在 GTK3.4 中）。我找不到有关使用 ColorChooser 对话框的示例。如果有人可以帮助我实现 ColorChooserDialog，我将不胜感激。
valac --pkg gtk+-3.0 -X -lm gtk-theme-config.vala -o gtk-theme-config
