Why would the order of Tabs in a JTabbedPane affect if the content of the tab works as expected?
I am writing my first advanced application and am having some trouble with my JTabbedPane. Here's what I have:
public ProjectTracker() {
initialize();
newJobTab();
newUpdateTab();
newReportsTab();
}
newJobTab(), newUpdateTab() and newReportsTab() are placed into a JTabbed pane within the initialize() method. Each create an instance of a GUI class that I made. It basically has a bunch of Text fields, and comboboxes, etc. and they interact with a database to either populate the fields or collect info from the fields.
The functionality of the buttons on the tab are the main difference between the three. Individually, each tab works as I would expect it to. When I place them in the Tabbed pane, only the third tab works properly. If I switch around the order, it is the same deal. Whichever one is the third tab is the only one that functions the way I want.
Here is my revision to my original post...now with code.
public class SampleTracker {
private JFrame frmProjectTracker;
private JTabbedPane tabbedPane;
public String Title;
SampleTJV newJobPanel;

EventQueue.invokeLater(new Runnable() {

try {
SampleTracker window = new SampleTracker();
window.frmProjectTracker.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}

ColumnSpec.decode("662px"),},
new RowSpec[] {
