As we know there are some view type in OpenERP, such as tree, form, kanban, graph, calendar, etc... I want to create a new custom view type for image area selection, it may looks like the geoengine. How can I create this new view type and the template? What are the steps that I have to do? starting from the controller, javascript, etc. Please help me with the steps. I can't find any technical guidance about this modification. Thanks in advance
