hello everybody,

lately i have started working on gef and have learned about creating the starting editor for gef with a palette, i got some source code also like of the shape example,

but one thing i m really confused is that the objects we create like the rectangle or ellipse is how created?, i saw several methods of, setting size location etc, but i didnt find any class or method for editparts,

for connections also there was a list which keep track of the connections made, but i didnt found any such list for the objects, please can anyone just give me a simple explanation or anything similar about the edit part or about my doubt??..,

thanks.

You should have an EditPartFactory which creates the edit parts and the getSourceConnections & getTargetConnections in the edit parts should give the connections

The interface is org.eclipse.gef.EditPartFactory. Look for implementations of this in your project

Not sure of why you don't want to use the factory, but the answer is yes, you can create EditParts without using the EditPartFactory. You have to override the createChild method in your EditPart

i asked so because in the shape examples source code there was no edit part factory used neither any abstract graphical edit part, so i was confused how the edit part are actually generated, and thats why i asked you,

createChild method is of which class??..,
