File Open Dialog Preview

[CoeurdeLeon 8]

What File Open dialog supports preview of the file to be opened.  I am using Delphi 12.2.

 

Thank you in advance.

TFileOpenDialog supports the same previews as Windows Explorer.

I would like to clarify.  I am looking for a Dialog that allows a user to select a file and that file content is displayed to the right.  This allows the user to select the file knowing he has the right file.

 

What delphi dialog achieves this objective?

 

Thank you in advance.

I have tried this and cannot see a preview of the file.  What am I doing wrong?

Set the fdoForcePreviewPaneOn flag on in the Options property. It should be noted however, that this will work only where preview of the selected file type is supported.

You might have missed to make the preview pane visible, either by clicking the corresponding symbol or by setting the appropriate option ad Dave already mentioned.

Of course, if there is no code to create a preview it obviously cannot be shown.

 

In case you think about creating your own previews used by Windows Explorer, I once wrote an article about how to do that with Delphi: Windows 7 Previews – the Delphi Way (not sure if that is still valid for more recent Windows versions, though).

SVG Shell Extensions contains examples of how to create Windows File Explorer extensions, both preview and thumbnail.
