Creation Order in JList

[mkornatzki]

Hi,

if i do the following the item of the list is not selected:
* i use a JFrame and place a JList somewhere
* set the Model with the editor
* set selectedIndex in PropertyEditor

Code looks like:

Code: Select all

         lst.setSelectedIndex(0);
         lst.setModel(new AbstractListModel() {
            String[] values = new String[]{"Eins", "Zwei", "Drei"};
            public int getSize() {
               return values.length;
            }
            public Object getElementAt(int index) {
               return values[index];
            }
         });


Should be:

Code: Select all

         lst.setModel(new AbstractListModel() {
            String[] values = new String[]{"Eins", "Zwei", "Drei"};
            public int getSize() {
               return values.length;
            }
            public Object getElementAt(int index) {
               return values[index];
            }
         });
         lst.setSelectedIndex(0);


cheers,

This is a good example of the limitations of the Swing JavaBean model and why we provide our own *wbp-component.xml files.

In this case, the setSelectedIndex() and setModel() methods have an implicit order dependency (an unnecessary one, IMO).

In the latest v7.6 build we will now always generate setSelectedIndex() after setModel() (currently, it depends on the order in which the user defines the properties).
