Unity TextField实现复制粘贴功能
发表于2018-08-21
很多人吐槽说unity的编辑器文本输入框GUILayout.TextField不能快捷键复制粘贴，实际上并非如此，主要是大家还没掌握到技巧，下面就和大家分享下使用TextField实现复制粘贴功能。
代码如下：
public static string HandleCopyPaste(int controlID)
｛
if (controlID == GUIUtility.keyboardControl)
｛
if (Event.current.type == UnityEngine.EventType.KeyUp && (Event.current.modifiers == EventModifiers.Control || Event.current.modifiers == EventModifiers.Command))
｛
if (Event.current.keyCode == KeyCode.C)
｛
Event.current.Use();
TextEditor editor = (TextEditor)GUIUtility.GetStateObject(typeof(TextEditor), GUIUtility.keyboardControl);
editor.Copy();
｝
else if (Event.current.keyCode == KeyCode.V)
｛
Event.current.Use();
TextEditor editor = (TextEditor)GUIUtility.GetStateObject(typeof(TextEditor), GUIUtility.keyboardControl);
editor.Paste();
#if UNITY_5_3_OR_NEWER || UNITY_5_3
return editor.text; //以及更高的unity版本中editor.content.text已经被废弃，需使用editor.text代替
#else
return editor.content.text;
#endif
｝
else if (Event.current.keyCode == KeyCode.A)
｛
Event.current.Use();
TextEditor editor = (TextEditor)GUIUtility.GetStateObject(typeof(TextEditor), GUIUtility.keyboardControl);
editor.SelectAll();
｝
｝
｝
return null;
｝
/// <summary>
/// TextField复制粘贴的实现
/// </summary>
public static string TextField(string value, params GUILayoutOption[] options)
｛
int textFieldID = GUIUtility.GetControlID("TextField".GetHashCode(), FocusType.Keyboard) + 1;
if (textFieldID == 0)
return value;
//处理复制粘贴的操作
value = HandleCopyPaste(textFieldID) ?? value;
return GUILayout.TextField(value, options);
｝
使用上面的TextField，就可以选中想要复制的文本按Ctrl+C,Ctrl+V 进行复制粘贴了。
