Tasks
Here are the tasks that are discussed in the first tutorial (see slides of tutorial 1).
The tasks should be finished by September 13. If you have
any problems, these can be discussed in the tutorial on Sept. 13.
Note that you do not need to submit the solutions; all solutions must be presented in
the "Tutorial presentation" in week 45 by each group. Each group should make sure
that they, as a group, are up to date with the tutorials.
The installation of Eclipse and of the ePNK, is a task every student should
do within the first two weeks!
- Install Eclipse with the extensions required for this course. See
http://www2.imm.dtu.dk/courses/02162/e13/project/eclipse-installation.html
for detailed instructions.
- Get acquainted with Eclipse as an IDE. See Eclipse help
(check slides of tutorial 1, p.7
where to look in the Eclipse help documents).
- Install the ePNK (version 1.0.1) as explained on the on the
project page
or the ePNK Home Page.
For creating new Petri nets in the ePNK and for using the ePNK editors,
have a look at the
ePNK Users manual (in particular Chapter 3).
- Implement and test a simple view for Eclipse that, for a selected resource,
shows the file extension and, if it is some standard extension (like pdf, doc,
txt, pnml, ...), also shows some information on the type of the selected resource.
The solution can be based on an example view that can be created by an
Eclipse wizard, which will be discussed during the tutorial on Sept. 6
(see slides of tutorial 1, pp.18-22).
Then, the major steps are
- Make the view class that was created by the wizard also implement an
ISelectionListener (and create the
selectionChanged method).
- Add this view (which now is a selection listener) as a listener
to the Eclipse workbench (in the
createPartControl method).
- Implement the
dispose method, where the view unregisters
as a listener again.
- The view has a so-called
viewer, which needs a so-called
content provider and a label provider. In your case, chose
ArrayContentProvider and LabelProvider
(both are part of the standard Eclipse distribution), during the
viewer setup in the createPartControl method.
- Implement the
selectionChanged method. When called, this
method should change the input of the viewer (by calling the
setInput method of the viewer) to an array of Strings
describing the selected file (based on its extension).
More details can be found in the slides of tutorial 1
(pp. 22-24 and pp. 3 and 5).
You can also get some inspiration from the "Readme example" that comes with
Eclipse (in particular the view).
The easiest way to install the "readme example" (and some others) is the
following (see also Eclipse Help "Platform Plug-in Developer Guide",
Section "Examples Guide", Subsection "Installing the examples"): Start the update
manager (Help -> Install New Software), select the standard
"Eclipse Project Update Site", look for "SDK Examples" (make sure that the
feature "group items by category" is NOT checked), select it, and install it.
In order to see the project in your workspace (and to change it), you
can start the "Plug-ins View" via "Window -> Show View ->Plug-ins".
In this view, you will find the plug-in "org.eclipse.ui.examples.readmetool";
Right-click on it, and select "Import as -> Source project". Then, you
will see this project in your resource browser or package explorer.
