New way to open DICOM volumes (or other type of directory component) in imp

Overview

Opening a DICOM image from a directory requires many unnecessary clicks. This is true for any other future "directory" components (component that can open a whole directory).

In CamiTK there is two types of component extensions:

• the classic type that can instantiate a component from a file
• the [directory] type that instantiates a component from a directory

Note: At the moment in CamiTK CE, there is only one type of [directory] component extension: the DICOM extension.

To improve the user experience (and completely avoid bugs linked to application global shortcuts such as closed bug 193 on bugzilla), here is something that I suggest:

1. modify the submenu File → Open Data Directory so that
   • it is managed by only one corresponding QAction
   • if their is only one [directory] component extension (check the size of ExtensionManager::getDataDirectoryComponents()), as it is at the moment in CamiTK CE, then the menu should be called Open XXX Directory where XXX is the resulting QString from the component extension getName() (therefore it should be called Open DICOM Directory in the current CamiTK CE). Otherwise it should be called Open Data Directory as before
2. Once triggered the QAction should:
   • if their is only one [directory] component extension, then go directly to the "open XXX directory dialog" (XXX = name of the component) and call the corresponding component extension open(...) method
   • if their is more than one [directory] component extension, then
     • look for all the registered/loaded ExtensionManager::getDataDirectoryComponents()
     • create a submenu with the corresponding menu item (as it is the case in the current version)
     • open the "choose directory dialog" and call the corresponding component extension open method.
3. (dicom component specific) if there is only one dicom series/exam in the directory, it should be selected by default in the dicom dialog (see class DicomDialog), and the user should only have to click on "Ok"

Therefore opening a dicom series should be performed in two (max three if there are more than one series) clicks

Relevant logs and/or screenshots

This is a follow up from the bug 193 (of the late bugzilla system).

Acceptance tests

• there should be a File → Open DICOM directoy menu in camitk-imp
• Clicking on it opens the dicom directory dialog
• if there is only one dicom series/exam in the directory, it should be selected by default in the dicom dialog
