Here is it:
btnInsertL.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent arg0) {
String textField1Content = textField1.getText();
if (textField1.getText().contains("Nova Categoria")) {
} else {
modelL.addElement(textField1Content);
}
}
});
Obviously, when I click in this "btnInsertL", it adds to my list a new element according to the name of the textField1. But with this, we have a subtle problem if we want the process to be more "dynamic":
It always add the new element to the END of the list, ignoring the selection. How could I add a new element according to the element that is already selected? I suppose this involves element-indexes of the DefaultListModel.
Element 1
Element 2
Element 3
Let us suppose that the "Element 2" is selected. When I click in the "btnInsertL", I want that the FOURTH element goes between the element 2 and the element 3.
Well, I think that this question is not that useless, I hope it helps someone too. I thank you all very much for the attention.
You checked the JavaDocs right?
Take a look at DefaultListModel.add(int, E)
检查DefaultListModel.add(int, E)
并使用ActionEvent的getSource()
方法查看选择了哪个按钮。
Thanks to the MadProgrammer I found the answer:
btnInsertL.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent arg0) {
String textField1Content = textField1.getText();
if (textField1.getText().contains("Nova Categoria")) {
} else {
modelL.add(listL.getSelectedIndex() + 1,textField1Content);
}
}
});
Problem more than solved! :).
