Java Swing:如何在TreeListeners:valueChanged之前调用stopCellEditing()? [英] Java Swing : How to invoke stopCellEditing() before TreeListeners:valueChanged?
问题描述
这是这些先前问题的后续内容:
This is a follow-up to these earlier questions:
- How to stop editing with DefaultCellEditor when a separate JBtton is pressed
- Sun Bug 4724980: JTable: Add API to control what happens to edits when table loses focus.
当我使用terminateEditOnFocusLost属性时，如下所示，当表格失去焦点时，我的CellEditor会正确停止
When I use the terminateEditOnFocusLost property, like below, my CellEditor correctly stops editing when the table loses focus:
jtable.putClientProperty("terminateEditOnFocusLost", Boolean.TRUE);
它也可以与我的JButtons一起使用.在处理按钮按下动作之前，为TableCellEditor 调用了stopCellEditing()方法.但是当我将其与JTree一起使用时，并且树的选择发生了变化，TreeSelectionListener.valueChanged方法被称为 before stopCellEditing().
It also works with my JButtons. The stopCellEditing() method is called for my TableCellEditor before the button press action is processed. But when I use it with a JTree, and the tree selection changes, the TreeSelectionListener.valueChanged method is called before stopCellEditing().
有人知道是否有一种方法可以强制首先调用stopCellEditing()，或者我是否应该为此问题做出一些解决方法?
Does any one know if there is a way to force stopCellEditing() to be invoked first, or should I just make up some work-around for this issue?
推荐答案
JTree在Swing中没有相似的客户端属性.
但是SwingX是SwingX的派生类，它是SwingX的派生类:invokeStopEditing.
JTree does not have similar client property in Swing.
But JXTree, a derived class from JTree, in SwingX does: invokeStopEditing.
如果您不能使用SwingX，则始终可以查看JXTree的源代码，并查看此StopEditing机制的工作原理:
If you can't use SwingX, you can always look at the source code of JXTree and see how this StopEditing mecanism works: JXTree SwingX 1.0 API Documentation and Javadoc (go to Source tab)
特别是从974行开始，创建了一个侦听器以监视KeyboardFocusManager等上的"permanentFocusOwner"属性更改...
Specially, starting from line 974, a listener is created to monitor "permanentFocusOwner" property change on the KeyboardFocusManager etc...
