Inner Class

[ceyesuma]

I have a JDesktopPane that opens and with a login it will add an InternalFrame with the InternalFrame 'innerclass'.

The problem is that when I want to add another InnerFrame to the desktop I can't call the inner class to add an Internal frame because it wants me to login again first.

Is there some way to add an InternalFraame from another class once the desktop is running alrady?
thanks

yup, if you code it correctly that should be possible.

That's all that can be said without knowing what convoluted code you produced to generate the behaviour you describe.

[ceyesuma]

lol. that is exactly the case. I will try to control the behavior of logging in better to get to the next error. thanks

I have never been able to call a class after it has been

initialized.
I would like to add a InnerFrame to my JDesktopPane if possible.

When I run the program it logs in if

isLoggedIn 

==false

with an actionPerformed from a combobox I need to skip creating

a new JDesktop and login but add a internal frame only.
How is this done?

I tried a new approach but I still have no clue.

public class ViewFrame {
     
   
    public ViewFrame() throws ProfileException, LoginException, FileNotFoundException,
            IOException, model.err.LoginException {
    }

    public void createViewFrame(String ln, JScrollPane scrollpane) throws ProfileException, LoginException,FileNotFoundException,IOException, model.err.LoginException, SQLException,ClassNotFoundException, InstantiationException,
IllegalAccessException {
        System.out.println("in createViewFrame()");
        Class thisClass =Class.forName("view.SchoolJDesktopPane");        
        SchoolJDesktopPane sdjp=(SchoolJDesktopPane)thisClass.newInstance();         
        sdjp.setIsLoggedIn(true);//if true no login();
        sdjp.createViewFrame(ln, scrollpane);
    }
}

I keep hearing that it can be done but is there a link or an example that describes how to call my Innerclass of my JDesktopPane after it is already running the JDesktop?

[jwenting]

you have an instance of a class, you can call methods on that instance if you have a reference to it.
If you don't maintain a reference, you should start figuring out how to do that (or how to get the JDesktop to give you one, no doubt it has functionality to do just that).

It Is encouraging to learn of using a reference to a class. Although I am not sure if I actually do this yet. It seams that I need to build the desktop and re-code the login 'panel' to be called as a actionPerformed() then it may not emerge unwanted later. Then I can see if calling a method using an instance is something I can work in.
