Office allows to ask for preview in the file open dialog.
Is it possible from VIP common dialogs?

[Thomas Linder Puls]

Yes.

[Ferenc Nagy]

How?

[Thomas Linder Puls]

Well, the editor example does it like this:

Code: Select all

predicates
    onFileOpen : window::menuItemListener.
clauses
    onFileOpen(_Source, _MenuTag):-
        FileName = vpiCommonDialogs::getFileName("*.*",["All files","*.*"],"Open text file", [],"",_),
        !,
        _ = editorForm::display(This, FileName).
    onFileOpen(_Source, _MenuTag).

Whether there is preview or not is controlled by the user.

Thomas,
Your code sample displays the Editor Package having its full power.
Windows 7 provides the preview button near to the upper right corner of the file selection dialog.
This button shows the preview - for certain kinds of files.

I beg your pardon for asking a question about a service of the operation system.
