在jTabbedPane中的jTextarea中添加文本

Question

I have a desktop program with 3 tabs i'm building in netbeans. There is 1 text input field below the three tabs. each tab has a jtextarea component. When i type in the text input field and hit enter i want it to add that text to the textarea contained by the currently selected tab.

I've been playing around with

jTabbedPane1.getSelectedIndex()

jTabbedPane1.getTabComponentAt()

How can i use the index to reference it back to the textarea associated with that tab?

Big java noob here.

Answer 1

The simplest way would be to use an array of JTextArea components corresponding to the order that they appear on the JTabbedPane .

JTextArea[] textArea = new JTextArea[3];
// assign textAreas... 

You could then set the text using the appropriate index:

int index = jTabbedPane1.getSelectedIndex();
textArea[index].setText(myField.getText());
