Hi friends,
here is one for the Java experts amongst you:
I am trying to program this little gui (Java 1.5.0_06 on W2k) that is having a combo box on top a button next to it and a scroll pane with a JTable in it below it.
Now.. My problem is that the "choose an Item" area of my ComboBox is partially hidden by the scroll pane container.
Is there a way to force the "choose an Item" area of my combobox to be always on top?
Here a short description on what this is supposed to do.
There is an instance of this class created by the applications main.
This guis is build,
the user is choosing a query from the combobox,
hits execute.
Then I am creating an instance of another class, that is doing some SQL queries against a Database, and giving 2 vectors to the setTable method of this class. The table is filled, added to the scroll pane.
So all in all not a big deal.
Help and/or pointers to useful information material is really appreciated.
cheers
Sebastian

Looks to me like it is a javax.swing problem. Quite common in fact.
Have you checked that the sizes you defined for all of your components fit in the size of your pane. The easiest way to make sure would be to allow dynamic resizing and make the main window a little bit bigger or a little bit less big. If everything then fits you know what you have to play with...
Might as well have to do with size of the text in the corresponding window that gives a min size to that pane?
Enjoy
