从jTabbbedPane的选定选项卡中获取jTextPane [英] Getting jTextPane from selected tab of jTabbbedPane

问题描述

我是java Swing的新手.我正在尝试开发一个工具，其中使用了Jtextpane作为编辑器. Jtextpane包含在Jtabbedpane中以满足我的要求.但是我已经将JTextpane插入到Jscrollpane中，然后插入到Jtabbedpane中.现在，当我选择一个特定的选项卡时，我应该获得相应的Jtextpane.我用过

jTabbedPane.getSelectedComponent();

但是它返回Jscrollpane.因此，我无法将内容保存在相应的Jtextpane中...

有人可以帮我解决这个问题吗?...

在此先感谢...

I am new to java Swing. I am trying to develop a tool, in which I used a Jtextpane as an editor. Jtextpane is enclosed in a Jtabbedpane to meet my requirement. But I have inserted the JTextpane in a Jscrollpane and then to the Jtabbedpane. Now, when I select a particular tab, I should get the corresponding Jtextpane. I have used the

jTabbedPane.getSelectedComponent();

But it returns the Jscrollpane. So, I am unable to save the contents in corresponding Jtextpane...

Can anybody plz help me to resolve this....

Thanks in Advance...

推荐答案

可以使用JScrollPane的getComponent(int)方法获取JTextPane吗?我假设如果JTextPane 是滚动窗格中的唯一组件，则将0 传递给getComponent(int)会得到JTextPane.

Can you use the JScrollPane''s getComponent(int) method to get the JTextPane? I''d presume that if the JTextPane is the only component in the scroll pane, passing 0 to getComponent(int) would give you the JTextPane.

首先获取选项卡(滚动面板)的选定组件:

How about first getting the selected component of the tab (which is the scroll panel):

JScrollPane jscrollpane =(JScrollPane)jTabbedPane.getSelectedComponent();

然后获取该组件的选定组件(将是文本面板):

And then get the selected component of that (which would be the text panel):

JTextPane jtextpanel=(JTextPane)jscrollpane.getSelectedComponent();

为了安全起见，您应该进行一些类型检查.另外，您可以使用getComponents 创建递归方法，以在选项卡或滚动面板上找到所需的文本面板.

祝你好运！

You should do some type checking though to be safe. Also, you could create a recursive method using getComponents to find the desired text panel on the tab or scroll panel.

Good luck!
