Subclassing QAbstractProxyModel to work with QFileDialog
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:
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?
As far as model is concerned you will need to implement rowCount(), data(), mapToSource() and mapFromSource().
Also you will need to have a custom QFileDialog because it has to return multiple files when selected.
Do you mean deriving QFileDialog or make my own file dialog?
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:
