hi, guys! I'm making my first project in GEF, so I'm a newbie here. I took as point of start the schema editor example, that you can find in the GEF homepage.
The project is almost ready, but I got a problem. When I add a new node, it appears in the top-left corner. I would like it to appear in the point where the mouse clicked. can someone help me?
thanks in advance,
Alisson

Alisson,
Are you adding the new node from a palette? Are you using GEF's
CreationTool?

The out-of-the-box behavior of the database table schema editor example is
to place newly added tables at 0,0. I considered this a bug. If we were
in school I think this would be marked "left as an exercise for the
reader" :-)
Anyhow I'm not in school anymore, so here's how I fixed it:
1. TableAddCommand needs a private field of type Point, and a setter
method:
private Point location;
/**
* Sets the desired location of the new item
*
* @param location
* the location to use
*/
public void setLocation(Point location)
{
this.location = location;
}
2. The execute() method of TableAddCommand needs to use the Point data to
set the bounds of the newly added table object:
Line 43:
// -1 for width, height means "resize to accomodate contents"
this.table.modifyBounds(new Rectangle(location.x, location.y, -1, -1));
3. SchemaContainerEditPolicy.getCreateCommand has to pass the point
(location) on to the table add command object:
Line 55: tableAddCommand.setLocation(location);
Hope this helps.
chris...
