Cappuccino 使用界面生成器从CPCollectionView拖放
我正在将Cappuccino 0.9.6与XcodeCapp一起使用。我有一个CPCollectionView,其中填充了CPImageView子类型项(ThumbnailView)。现在我希望这些项目是可拖动的 我将示例中的指令改编为我的xcode接口(拖动目标尚未实现),但是,这些项不可选择,更不用说可拖动了。有什么问题吗 AppController.jCappuccino 使用界面生成器从CPCollectionView拖放,cappuccino,Cappuccino,我正在将Cappuccino 0.9.6与XcodeCapp一起使用。我有一个CPCollectionView,其中填充了CPImageView子类型项(ThumbnailView)。现在我希望这些项目是可拖动的 我将示例中的指令改编为我的xcode接口(拖动目标尚未实现),但是,这些项不可选择,更不用说可拖动了。有什么问题吗 AppController.j @import <Foundation/CPObject.j> @import "MediaController.j" @
