program wait for input

Hello,

I have a program that pops up a dialog box that will gather user input. I'd like execution to stop until the user has supplied that input and pressed "OK" on the dialog box.

I thought that gSystem->ProcessEvents() would force that wait, so I have the present code snippet:

// Pop up a dialog box and get info about the file.

      SimpleDialog();               // pop up the dialog
      gSystem->ProcessEvents();     // should wait for input?
      cout << "File has " << ncols << " columns" << endl;

The output from the cout line shows that the system is not waiting for input.

Thanks for any help,
