GMF 1.0 New and Noteworthy - Released: June 30, 2006
Export Big Diagrams to Images
Huge diagrams that fail to be exported to a single JPEG, JPG, GIF, PNG or BMP image (Bug 160386), now can be exported to a number of images that combined together will display the image of the whole diagram (or selected editparts). An HTML file is created to view the whole image. The HTML file essentially contains a table, each cell of which is occupied by the appropriate piece of diagram's image (i.e. by the image file corresponding to that particular piece of the diagram). GMF's UI for exporting diagrams to images has been added a checkbox "Export to HTML", which will trigger exporting the diagram as described above.
The result of exporting a huge Geoshape diagram to HTML with the HTML file opened looks as follows:
Label Enhancements in the GMF Runtime
There were a number of usability bugs with the WrapLabel implementation and the TextDirectEditManager. The TextCompartmentEditPart and its helper classes also made assumptions that the figure of a TextCompartmentEditPart was a WrapLabel, making it difficult for clients to use any other label figures.
A new WrappingLabel has been created that uses GEF's Flow Figure classes to perform that text wrapping. The TextCompartmentEditPart and its helper classes have been modified so that there is only a dependency on a new interface, ILabelDelegate, which a client could use with any figure for displaying the label. The TextDirectEditManager has been changed to fix a few bugs and work with an ILabelDelegate.
Existing GMF Runtime clients need not make any code changes to enjoy the benefits of the new WrappingLabel as the existing WrapLabel subclasses the new WrappingLabel. However, it would be wise to test all behavior with text on diagrams to ensure there are no regressions.
A document which discusses the design, gives an overview of the changes made, and provides documentation for the clients on how to use the new WrappingLabel is attached to the bugzilla: Bug 162932
Group/Ungroup Functionality in the GMF Runtime
The GMF Runtime now has the ability to group and ungroup shapes. Check out the GMF Runtime Logic and Geoshapes Examples to see the new functionality. It's under the Format menu when multiple shapes are selected. The group/ungroup actions are not contributed by default by the GMF Runtime. To learn how to adopt the group/ungroup in a GMF diagram, see the document attached to Bug 111892. Note at this point, the group/ungroup functionality has not yet been adopted by the GMF Code Generator.
Additional Snap to Grid Functionality in the GMF Runtime
The GMF Runtime has extended the use of snap to grid for two existing components.
Arrange All / Arrange Selection
Edit parts selected will now snap to grid at the end of the arrange session, if the snap to grid property is enabled. Bugzilla 119252 A screen shot of a resulting "arrange all" action with snap to grid on is shown below.
Connection Bend Points
Connection bend points will now snap to grid when being dragged by the user, if the snap to grid property is enabled. Bugzilla 194282 A screen shot of a bend point snapped to grid is shown below.
GEF Alignment Feature: Snap To Geometry added in the GMF Runtime
The GMF Runtime now has the capability to allow edit parts to snap to each other when editing. Bugzilla 188974 Snapping to other edit parts inside compartments are also supported. However, edit parts can snap to other edit parts that share the same parent. (e.g: edit parts inside a compartment can only snap to each other) Some screen shots of this new feature are shown below.
