Hello guys, please I need help. I have develoed an application using net bean,
- I’m making project in java API 6. I’m using “Net Beans 7.1”.
- I want to use “JInternalFrame” in my project
- I made another package and made “JInternalFrame” there. And then call it in my main application window by firing action performed event on “JMenuItem”.
- It works fine but only one problem occurs that is, if i click on “JMenuItem” again and again, new “JInternalFrame” of same instance are opening, How can i stop that?
- I want that, if I open “JInternalFrame” once and then i again click on “JMenuItem” to open the same “JInternalFrame”, it Should do nothing or it shows the window which already opened and minimized.
sample code:
private void empDataActionPerformed(java.awt.event.ActionEvent evt) {
Emps employees = new Emps();
desktop.add(employees);
employees.setVisible(true);
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
employees.setBounds(230, 40, screenSize.width / 2 - 80, screenSize.height / 2 + 105);
}
Thanks In Advance!
