[platform-swt-dev] New to Java and SWT

["Smith, Mike" <Mike_Smith@xxxxxxxxxxxxxxxx>]

Title: Message

Hi,

I'm taking a java class and one of the things i need to do for a final project is create a program that has 3 or 4 queries over a database file.  For extra Credit we can turn this into a GUI.  We haven't gone over GUI at all and when we do it will be SWING.  However, i would like to do this in SWT.  I've been looking at some samples, and have created my first screen.  This screen allows the user to enter a Id and Password to connect to the database.  Conceptually this is what i would like to do

 

Display  Signon Screen.  Connect to database when button is pressed.

Then display a second screen that has the available options.  ie list team info by owner id, etc, etc.   As i press  a button for each query  on the same panel, i would like to display instructions and the corresponding text fields etc for enter my search criteria..

After entering search criteria, i would like to display a new window showing results. 

 

Now the problem is that i don't have a clue how to create a new window.  When i try to do this, i get a 'Thread exception'.  I think it has to do with needing to use syncExec and runnable, but i can't really figure out how to take what i have currently and implement this. 

 

Can someone provide me a simple example of a 2 window application. 

 

here is what i have currently.  keep in mind it doesn't really do anything yet, i'm just trying to figure out the GUI part.  

 

Thanks

 

Mike
