Problem with native Windows OpenDialog

Hi,

I just ran into a problem with the native Dialog for Windows that is
created when requesting a filename with the following code:

Dialog
        requestFileNameWithMessage: 'Open'
        default: '*.txt'
        version: #mustBeOld
        ifFail: ['']
        for: nil.

this opens a filerequest and this window is modal, just like it has to be.

If I call another Dialog right before that one, then this native dialog
is not modal, and in some cases also created behind all the other windows.
Try this code:

Dialog warn: 'You will see something wrong now:'.
Dialog
        requestFileNameWithMessage: 'Open'
        default: '*.txt'
        version: #mustBeOld
        ifFail: ['']
        for: nil.

Adding a Delay for some seconds between these two dialogs doesn't help, too.
When a different window is selected during the delay and that one is the
active window when the native dialog appears, then the native dialog is
modal again.

Dialog warn: 'You will see something wrong now:'.
(Delay forSeconds:6) wait.
Dialog
        requestFileNameWithMessage: 'Open'
        default: '*.txt'
        version: #mustBeOld
        ifFail: ['']
        for: nil.

Also stepping through the code with the debugger works fine.
Maybe someone has a solution for this bug.

Kind Regards
Karsten

I'd noticed this too, even with new FileDialog protocols (which Dialog falls
back to anyway in 7.4), and it seems to happen almost every second time
where native dialog would come up but stay behind all the VisualWorks
windows... Slightly confusing for some users.

Cheers!

It is not a bug, but the way modal windows are created in windows

The culprit here is the "for:nil" portion.  Give it a window  like

  Dialog
      requestFileNameWithMessage: 'Open'
      default: '*.txt'
      version: #mustBeOld
      ifFail: ['']
      for: myApplication builder window (or Dialog defaultParent)
.

and it is going to be modal- to the calling app window...
