Refresh JTextField (Swing) 1

[adrianjohnson]

I'm developing software which will retrieve some information from a database, but I'd like to have a text field which will be display "Working" whilst the system is getting the data. The user will activate this part by selecting the table name from a JTree.

So, I've added the text field, set it's text, but when the user selects the table name from the JTree, the text field doesn't update. When the system's finished, and I set the text field to "Waiting" - that works ok.

Some example code (off the top of my head, as I'm not at work):

// Set the text in the text field.
lblStatus.setText("Waiting");
 
// Do something.
 
// Now get the info from the database.
lblStatus.setText("Working");     // This line not working!
fillTable();    // Call method to get data.
lblStatus.setText("Waiting");     // This line does work.

If I print to the bebug window at those points, it works fine - it's just the text field that isn't updated.

Any ideas?

Thanks,

Adrian,

Try forcing the window to repaint...
It's nice to have prompts, but if the fillTable() is always executing at a constant rate (i.e. the table isn't expanding) then you may want to reconsider having the extra prompts.

lblStatus.setText("Working");     // This line not working!
[red]lblStatus.update(lblStatus.getGraphics());[/red]
fillTable();    // Call method to get data.
lblStatus.setText("Waiting");     // This line does work.

Brilliant, Ron - that worked a treat.

I hadn't come across it before, as I did a search on this and other forums.

Thanks for your help.
