376Chapter 16Getting in the Swing of Things: Designing a GUI for BudgetProbutton and account name information left-justified, and stack the Totaland Remaining labels vertically on top of each other. Do you always needto create new intermediate containers? Can you do it just withGridBagLayout?2. Modify the BudgetPro program so that it displays a pop-up dialog whenyou try to create a subaccount with more money than is available to thataccount.3. Modify the dialog used for creating subaccounts, so that it also promptsfor the owner’s name. This can get more complicated if you want to allowonly valid user names. Instead, let any name be entered and create a Userobject for it.4. Modify the BudgetPro program and associated classes to allow for editingof the values in the accounts, so that the user can change dollar allocations.Start with the ability to edit the value in the table (custom editor).5. Replace the JTable (and the View Subaccount button) with a JTreeobject.
