Hi everyone!
The problem is as follows.
There're two classes:
public class MyFrame extends JFrame
{
public MyFrame()
{
...
}
public void someFunction()
{
MyDialog dlg = new MyDialog(this);
dlg.setModal(true);
dlg.show();
}
}
public class MyDialog extends JDialog
{
public MyDialog(Frame parent)
{
super(parent);
...
someOtherFinction();
}
/**
* This function doesn't return for a long time, as it performs
some complex math operations.
*/
public void someOtherFunction()
{
...
}
}
The first class represents my application's main frame. The second one
is a dialog which may be called as a child of the main frame. But this
dialog is being constructed for quite a long time (due to
someOtherFunction() working -- see code above) -- about 30 seconds on
my CPU. As a result, parent window is not being repainted. I need to
explicitly repaint the main frame (parent window) from within
someOtherFunction() (it contains a cycle). But standard methods such
as revalidate() and repaint() do not help. Note: when the parent needs
repainted, the child is not constructed yet.
Who knows, how I can fix this problem without dealing with threads?
Any suggestions will be appreciated.
Thanks in advance.
Andrew.
