RE: [platform-swt-dev] FileDialog/DirectoryDialog under Debian

You have to explicitly close the shell,
it won't close for free - try the attached snippet below. BTW, I'm not
sure why you are parenting the dialog on a SYSTEM_MODAL, ON_TOP shell -
this seems wrong. System modal means modal to all other windows on your
desktop! A  FileDialog will be modal to all other shells in your app
(depending on which version of GTK you are running, a shell might seem
to take focus, but you shouldn't be able to click on any other controls.
If you can please open a bug). 


public
static
void
main(String[] args) {
        
        Display
display = new
Display();
        final
Shell shell = new
Shell(display, SWT.ON_TOP | SWT.SYSTEM_MODAL);
        shell.setLayout(new
GridLayout(1, false));
        shell.setBounds(50,
50, 100, 100);
        shell.open();
         
      
        final
FileDialog dialog = new
FileDialog(shell, SWT.OPEN);
        String
s= dialog.open();
        System.out.println(s);
        if
(s != null)
{
         
      shell.close();
        }
        
        while
(!shell.isDisposed()) {
         
      if
(!display.readAndDispatch())
         
              display.sleep();
        }
        display.dispose();
}

Objet : [platform-swt-dev] FileDialog/DirectoryDialog under Debian
 
Hello,
 
I have a problem with both FileDialog and
DirectoryDialog under Debian Lenny (GTK2) : when such dialog is closed
(either when double clicking an item, using select or cancel button, or
simply closing it), the âopenâ method returns with the expected result,
but the shell remains open !
The shell is not repainted anymore, so
it seems to be âdisposedâ, but itâs still visibleâ
Moreover, if I open another file or directory
dialog, the previous one disappears!
Note that the parent shell is created with
style âSWT.SYSTEM_MODAL
| SWT.ON_TOPâ
(and Iâd like to keep this styleâ)
 
I tried with both SWT 3.4.2 and SWT 3.5.1â
 
Here is the code Iâm using :
 
// The following Shell
is not made visible. We only show the file dialog.
final
Shell shell = new
Shell(display, SWT.SYSTEM_MODAL
| SWT.ON_TOP);
         
  try
{
         
        final
FileDialog fd = new
FileDialog(shell, SWT.OPEN);
 
// ... Setting of file
dialog properties : text, filterPath, etc. ...
 
         
        fd.open(); //
Opens correctly, and return normally, but the dialog remains open !
 
// Get the correct result.
         
        final
String[] selectedFiles = fd.getFileNames();
 
         
        //
... Process the result ...
 
         
  } finally
{
         
        //
I tried to close the parent shell in a async runnable just in case... But
it doesnât change anything.
         
        display.asyncExec(new
Runnable() {
         
              @Override
         
              public
void
run() {
         
                   shell.close();
         
                   shell.dispose();
         
              }
         
        });
         
  }
 
Iâm currently trying to remove âSWT.SYSTEM_MODAL
| SWT.ON_TOPâ
just to see if it changes something, but I really need the dialog to be
displayed on top and to block other running applicationsâ
 
Any help is welcome! Thanks in advance!
