Creating a dynamic tree like user interface with qml
I am trying to create an application where all the data is organized in a tree like structure stored in many xml files.
There is a root.xml file containing a bunch of elements.
Each element contains the data i want to display to the user and it may also contain a “link” to another xml.
The elements will be displayed in a list view to the user.
If an element contains a link to another xml file I will allow the user to select that element to show another list of items.
The linked xml file will have the same rules as the root.xml; may contain links to other xml files.
This will allow me to configure the application’s tree with xml files.
I would like to know the best way about doing this.
I have created a way that dynamically creates list views, but it seems that I need to put lots of work around in my qml application to make things stable and not crash or do things that were not intended.
I need to be able to show the parent and child xml lists at the same time for a nice looking transition, but once the transition is over I will only need to show one list. Another challenge is that I need the last selected item the user saw when leaving a list to be remembered; so when the user returns to that list it will be as they left it. I am doing that by storing the indexes of each list’s selected item in an associative array, and that seems to work.
Denis, your approach sounds pretty interesting. I will have to use two list views, but I could do a round robin kind of thing for the two list views. And I would have to store a history (stack or have children store links to there parent xml file) so the user could navigate in both directions.
Thanks for the ideas
