Issue
Sirs,
In short, my question is "how do you clone a jTable in a GUI developed in Netbeans."
In a little more detail, I have a jTabbedPane that consists of two tabs - myTab1 and myTab2. Both tabs have a jTable that will display columns from a derby database. Any time the data in the database is updated, I want both jTables to update to reflect the new information. Essentially, the two jTables will show identical data in each cell, and any time a change is made to one there will be an automated change to the other.
Obviously, I could do this long-hand. Any time a subroutine (that changes the data in the database) is executed, I could have an UpdateMyTable1() and an UpdateMyTable2() routine to make the changes. However, in my case the UpdateMyTable1() function/method/subroutine would need to be a rather lengthy one, and UpdateMyTable1() would consist of almost identical code to UpdateMyTable2(). There would be a lot of redundant code.
In Neatbeans, is there a way to instantiate (or otherwise create) two jTables in such a way that they always mirror each others contents without writing the code out long-hand?
Solution
The solution is simple: don't think about "cloning" but instead simply have both JTables share table model. Something as simple as
table1.setModel(table2.getModel());
could work.
If they share models, then changes in the model will be shown equally in both JTables.
