Modal dialog stops method finishing.

Hi,

I'm creating a JDialog that is modal, however it seems that anything after the setVisible(true) prevents the rest of the method finishing. I'm populating a list box, but would like to do it once the dialog is visible (so that error messages appear more in connection with what is displayed), but the function that populates the list box does not get called after the setVisible(true). Possible work arounds?

Thanks,
Uni

The 'setVisible()' hands control over to the dialog until the dialog code say's 'setVisible(false)'.
Then, and no earlier, your method continues.
In between only the dialog buttons can put it to work.
Usually the constructor of a dialog takes up all the data.
I presume the ListBox is displayed in the dialog?
Then do the buildup entirely in the dialog's constructor.

"I presume the ListBox is displayed in the dialog?"
Correct.

"Then do the buildup entirely in the dialog's constructor."
The problem with reading in the data before setVisible(true) is called, is that if there is a problem a message box is shown, but it would appear before the dialog is shown. So the message box appears disconnected from the contents of the dialog box.

Is there anyway to get the readData function called inbetween the dialog being shown and control being passed over to the buttons?

I don't see the problem to pop the messagebox from the constructor, where the data is available.
There is a way to 'activate' code in a dialog after the setvisible, by starting a 1-shot timer
from the constructor with a delay of 1 mSec, but maybe that's not what you want.
