| − | == Why should I use GEF? == | + | === Discussions === |
| − | GEF enables developers to easily create rich graphical editors within Eclipse. GEF has been used to build a variety of applications, including state diagrams, activity diagrams, class diagrams, GUI builders for AWT, Swing and SWT, and process flow editors. For more information on GEF features, please see the [http://www.eclipse.org/gef/overview.html?cvsroot=Tools_Project Project Overview].

| − | == Which operating systems does GEF support? == | + | === Public Healthcare Serveices === |
| − | GEF is written in pure Java and should run on all operating systems officially supported by the Eclipse platform. It's primarily tested on Windows and Linux (GTK and Motif). See the readme file that came with your installation of GEF for specific versions.
| + | This section contains a list of known public standard healthcare services. |
| | | | |
| − | == How is GEF licensed? ==
| + | The listed services are actors on one of the [http://www.ihe.net IHE] profiles. OHF implements components that interacts with these services. The purpose of the list is to help developers test the plugins they develop, to validate full interoperability across vendors, and to validate comliance with the standard. |
| − | GEF if licensed in accordance with the [http://www.eclipse.org/legal/epl-v10.html Eclipse Public License]. Third party components built using GEF are made available under their own licenses.

| − | == Why isn't GEF showing up in Eclipse? ==
| + | |
| − | After installing GEF by extracting it to the necessary directories, it may be necessary to accept the changes within Eclipse. This can be accomplished by going to Help->Software Updates->Manage Configuration and right-clicking on Eclipse Platform. Select "Detected Changes..." from the menu and click Finish to complete the installation. This is the most common cause of the install not showing up in the aforementioned Plug-in Details view.

| − | | + | |
| − | == When should I use GEF and when should I use just Draw2d? ==
| + | |
| − | The simple answer to this question lies in their names. Draw2d is for drawing. GEF (or Graphical Editing Framework) is for editing.
| + | |
| − | | + | |
| − | Draw2d is used for rendering and layout. If all you want is to display data, all you need is Draw2d. If, on the other hand, you want to be able to manipulate that data, you should use GEF. GEF adds important functionality for editing -- commands for changing your model, a palette and tools for selecting and manipulating the edit parts that represent your model, direct edit, accessibility support such as keyboard navigation, native drag and drop, and much more that I've probably missed.
| + | |
| − | | + | |
| − | There may be only a few of these functions that you need -- for instance, you may just want to add drag and drop support so that you can drag files from the navigator or a file explorer and drop them onto your application/view, but otherwise only need to display the dropped data and not manipulate it. This is where the line gets blurred. You'll need to weigh the advantages and disadvantages of both options. On the one hand, you could move to GEF, get a bunch of functionality that you don't need and increase the complexity of your code. Or you could stick with Draw2d and implement the functionality you need yourself, maintaining a much simpler implementation. For the above example, I would personally implement the drag and drop function myself and stick with Draw2d. However, you should also consider future needs. You may want more of these functions down the road and moving to GEF now may be helpful.
| + | |
| − | | + | |
| − | == How do I redistribute GEF with my application? ==
| + | |
| − | First off, you should probably check out the [http://www.eclipse.org/legal/legalfaq.html Eclipse.org Legal FAQ], the [http://www-106.ibm.com/developerworks/library/os-cplfaq.html CPL FAQ], and/or the [http://www.eclipse.org/legal/cpl-v10.html CPL] itself. More information forthcoming.
| + | |
| − | | + | |
| − | == How do I ask questions? ==
| + | |
| − | Questions about the use of GEF in user projects that are not addressed in this FAQ should be posted to the [news://news.eclipse.org/eclipse.tools.gef GEF newsgroup]. Questions and comments regarding the implementation of GEF itself should be posted to the [https://dev.eclipse.org/mailman/listinfo/gef-dev GEF mailing list].
| + | |
| − | | + | |
| − | == How do I report a bug or request a feature? ==
| + | |
| − | GEF, like the Eclipse project, uses [http://www.bugzilla.org/ Bugzilla] as its bug and feature tracking system. Entering a bug\feature report is as simple as filling in a web form on the [http://dev.eclipse.org/bugs/ eclipse bugzilla page]. The first time you enter a bug you will need to [http://dev.eclipse.org/bugs/createaccount.cgi create a new bugzilla account] for yourself by providing an email address and choosing a password. Before submitting a bug, please be sure to check the list of [https://bugs.eclipse.org/bugs/buglist.cgi?bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&email1=&emailtype1=substring&emailassigned_to1=1&email2=&emailtype2=substring&emailreporter2=1&bugidtype=include&bug_id=&changedin=&votes=&chfieldfrom=&chfieldto=Now&chfieldvalue=&product=GEF&short_desc=&short_desc_type=allwordssubstr&long_desc=&long_desc_type=allwordssubstr&keywords=&keywords_type=anywords&field0-0-0=noop&type0-0-0=noop&value0-0-0=&cmdtype=doit&order=Reuse+same+sort+as+last+time open GEF bugs] and [https://bugs.eclipse.org/bugs/buglist.cgi?short_desc_type=allwordssubstr&short_desc=&product=GEF&long_desc_type=allwordssubstr&long_desc=&bug_file_loc_type=allwordssubstr&bug_file_loc=&keywords_type=allwords&keywords=&bug_status=RESOLVED&bug_status=VERIFIED&bug_status=CLOSED&emailtype1=substring&email1=&emailtype2=substring&email2=&bugidtype=include&bug_id=&votes=&changedin=7&chfieldfrom=&chfieldto=Now&chfieldvalue=&cmdtype=doit&order=Reuse+same+sort+as+last+time&field0-0-0=noop&type0-0-0=noop&value0-0-0= recently closed GEF bugs].
| + | |
| − | | + | |
| − | == Can I develop a standalone GEF application without use of the Eclipse platform? ==
| + | |
| − | The official answer is No, this is not supported. The main reason involves the use of an Eclipse-specific file titled plugin.properties which GEF uses for string externalizations. However, since GEF is an open source project, modifications to the GEF codebase could potentially allow a GEF editor external to Eclipse.
| + | |
| − | | + | |
| − | == How can I get started on my GEF-based editor? ==
| + | |
| − | The best place to investigate initially is the [http://www.eclipse.org/gef/developer/faq.html#install_doc GEF documentation]. This provides high-level concepts of GEF and Draw2d. There is also a sample GEF editor that can be downloaded at the [http://download.eclipse.org/tools/gef/downloads/ GEF download page] . The source code is made entirely available.

| − | == How do I instrument domain model changes that support undo/redo ==
| + | |
| − | | + | |
| − | You can define custom request types that represent model changes for your
| + | |
| − | domain. An example would be how the logic example increments / decrements
| + | |
| − | the LED model item. The IncrementDecrementAction creates a new request constant -->
| + | |
| − | ...
| + | |
| − | request = new Request(INCREMENT_REQUEST);
| + | |
| − | ...
| + | |
| − | | + | |
| − | Then the request is sent to the selected objects on the diagram surface. If the selected object is an LEDEditPart, then it has a custom EditPolicy installed on it's EditPolicy.COMPONENT_ROLE (LEDEditPolicy) that is used to handle model changes. This EditPolicy is instrumented to understand the INCREMENT_REQUEST in it's getCommand method. It then returns a custom command that can handle undo/redo that will get executed on the command stack.
| + | |
| − | | + | |
| − | @see LEDEditPolicy#IncrementDecrementCommand
| + | |
| − | | + | |
| − | If the request is not understood by the selected EditPart (i.e. no EditPolicy installed on EditPolicy.COMPONENT_ROLE), then a null command is returned. This can indicate to the action that it should be disabled for the user.
| + | |
| − | | + | |
| − | == How do I do move an element from one container to another ==
| + | |
| − | If you're moving an element from one container into another, first you need to consider the model changes that persist the container changes. To do that, an EditPolicy for removing the model element on the source (ContainerEditPolicy) is needed and an EditPolicy for adding the model element (XYLayoutEditPolicy).
| + | |
| − | | + | |
| − | If we consider moving a LED from the diagram to a Circuit:
| + | |
| − | First to remove it from the owned container using the OrphanChildCommand in Logic designer which will remove it from the first container.
| + | |
| − | @see LogicContainerEditPolicy#getOrphanChildrenCommand
| + | |
| − | | + | |
| − | Then it is added to the target container using an AddCommand
| + | |
| − | @see LogicXYLayoutEditPolicy#getAddCommand
| + | |
| − | | + | |
| − | These instrument the model changes. Then the EditParts will listen to the model changes accordingly. Both the DiagramEditPart and CircuitEditPart are LogicContainerEditPart which override the method getModelChildren. Subsequent calls to refreshChildren will synchronize the EditPart children with the model children. Alternatively, for performance they can listen to the model changes specifically which will invoke addChild or removeChild based on the corresponding event.
| + | |
| − | @see LogicEditPart@propertyChange
| + | |
| − | | + | |
| − | == How do I do "X" when the User double-clicks? ==
| + | |
| − | Mouse events are handled by a Draw2D event dispatcher. When using GEF, a DomainEventDispatcher is used which allows heterogeneous handling of mouse events. Mouse presses in general can either be processed by a Figure, or by a Tool. A double-click is also a click, so the first event is a MouseDown, followed by a DoubleClick event. When a MouseDown is dispatched, the event dispatcher will continue to send events to either the Figure or Tool until the Mouse is released. So this means if the Tool processes MouseDown, it continues to get DoubleClick, dragging, and MouseUp. If a Figure consumes the MouseDown event, it will receive these events.
| + | |
| − | | + | |
| − | The GEF SelectionTool already processes double-click and will send a SelectionRequest to the target EditPart under the mouse of the type REQ_OPEN. The request is sent by calling EditPart.performRequest(Request). This is the preferred way to do something in response to double-clicks.
| + | |
| − | | + | |
| − | == How do I find the location of the context menu? ==
| + | |
| − | Often, GEF clients want to know the location of the context menu so that, for instance, new parts can be created or pasted at that location. The context menu can be brought up via the keyboard (Shift+F10) and there's no guarantee that the mouse cursor will be over the editor (or even the active window) when the context menu comes up. Hence, we recommend to do this in a location-neutral manner. For instance, new parts can be added to the top-left visible corner of the selected container, or the location can be determined based on the location of the part that was copied.
