<![CDATA[Subclassing QAbstractProxyModel to work with QFileDialog]]>Hello,
I would like to create a custom QFileDialog that has a special behaviour:

I'd like the files in the directory to be represented as 1 file if they belong to such a sequence:

@file0.jpg
file1.jpg
file2.jpg
...@

would be represented as only 1 item: @file#.jpg@

Also whenever the user would select file#.jpg I'd like the file dialog to return all the associated file names.

After reading all the Qt documentation I find it really hard to pull-off.
I figured I'd have to subclass @QAbstractProxyModel@ and call @QFileDialog::setProxyModel@ but I don't really know what to do with the @QAbstractProxyModel@
Does anybody have any idea on how to get started on this?

In the later case, how would you custom the view so it has a behaviour as such :

  • when the user clicks the directory, it show the content of the directory, it does not unfold an item in a QtreeView

Here is a picture of what I'd like it to be,

and here is what I have with QTreeView:

Also you will need to have a custom QFileDialog because it has to return multiple files when selected.
