    <p>I have a combobox that is put in a 20x20 field, so only the button is shown. </p> <p>When the user clicks the button, it drops down a popupmenu that is 150 wide (using Mark McLaren's WiderDropDownCombo solution). </p> <p>However, the button is on the rightmost side of the panel, that contains 2 other fields (both JTextFields). When I open the dropdown menu, it starts from the top-left corner by default and goes out of bounds for the area. I need to change that so the combobox would appear beneath all fields. </p> <p>I've tried messing with CellRenderers and orientation, but It doesn't seem to work. Anyone know something about the solution?!</p> <p>My code for the part that creates the field is following :</p> <pre><code> HistoryProcessor processor = new HistoryProcessor(field.getName().toLowerCase()); amount = new JTextField( amountString ); currency = new JTextField( currencyString ); amount.setMinimumSize( new Dimension(94, 20) ); amount.setPreferredSize( amount.getMinimumSize() ); amount.setMaximumSize( amount.getMinimumSize() ); currency.setMinimumSize( new Dimension(30, 20) ); currency.setPreferredSize( currency.getMinimumSize() ); currency.setMaximumSize( currency.getMinimumSize() ); popupButton = processor.populateHistoryBox(); popupButton.setWide(true); popupButton.applyComponentOrientation(ComponentOrientation.LEFT_TO_RIGHT); popupButton.setMinimumSize(new Dimension(20, 20)); popupButton.setPreferredSize(popupButton.getMinimumSize()); popupButton.setMaximumSize(popupButton.getMinimumSize()); panel.add(amount, BorderLayout.WEST); panel.add(currency, BorderLayout.CENTER); panel.add(popupButton, BorderLayout.EAST); popupButton.addPopupMenuListener(new MoneyHistoryListener(this)); </code></pre> <p>where amount is the first field, currency the second and popupButton is the combobox. it is automatically filled by HistoryProcessor.

    1. COfrom this code and description is (only) clear that Mark McLaren's WiderDropDownCombo has bug, or popupButton.applyComponentOrientation(ComponentOrientation.LEFT_TO_RIGHT); is proper (look like as) output from applyComponentOrientation, but everything is about guessing

    2. COI don't think that the DropDownCombo is bugged. http://pastebin.com/rpGcxH2w the only change I've made myself is that it's not text-dependant, but you can set a static size.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
