I have designed a meta model for my systems, and I want to create a graphical editor to facilitate the creation of a model. Video tutorials would ofcourse be welcome.
SWT Draw2D Example : 2D « SWT JFace Eclipse « Java
Shapes Subclasses vraw2d the Shape class contain non-rectangular figures that know how to fill themselves and provide a border of configurable width and line style, and include support for XOR drawing. Operations to manage the tutoria, place in the figure hierarchy, including adding and removing children and accessing them or its parent figure.
Email Required, but never shown. Subclasses of ConnectionLocator are used for tutoeial figures that are attached to a Connection. Because they simulate a heavyweight graphics system within a single heavyweight window, they allow you to create a graphically complex display without consuming a lot of system resources.
It notifies its listeners when the figure it is associated with is moved. Sign up using Email and Password. A complete coverage of Draw2D in depth is beyond the scope of this book. Widgets Draw2D includes figures which allow you to create lightweight widgets that can be used when you need an input control within your Draw2D application.
The locator ensures that the figure stays “attached” to the Connection in the designated location as the Connection is moved. The advantage of daw2d systems is that they are much more flexible than the native windowing system, which is generally composed of rectangular components. You can see the basic structure of a standalone Draw2D application in Example Now you can spend more time learning how to make your app better.
DigitalTrainingStudio runs within your browser. Layouts LayoutManagers are used to manage the position and size of a figure’s child figures. Utility methods for drawing graphics.
3.2 Introduction to Draw2D
The AbstractConnectionAnchor class is the base class for anchors whose position is associated with a figure. The connection is routed to follow a set of points that the user specifies by manually dragging the Connection’s segments.
Can anyone suggest me any useful resources for the same. LayerPanes are figures designed to contain layers they can only contain layers. The tuttorial method invokes three more specific paint methods:. XYLayout — Places its children at the location and dimensions ddraw2d for the child.

Notice that the border does not have to be symmetrical. While designers focus on drawing the figure or shapes, the Draw2D Tutogial automatically writes the code for them.
