So where's the test file itself? Is there anything we can try already?
Nothing we can announce to users, just enough for me to play about with graph layout using inkscape instead of dia.
Caveats:
- There is no UI at all, unless you count the XML editor. E.g. there's no tool for creating connectors, nor do connectors disconnect or reconnect when you move the end point of a connector away from or to an object.
- Currently, any edits to curves are lost when either object is moved. Maybe this will be the next thing I'll work on.
- The XML representation should probably change.
- Implemented by listening for SPItem->_transformed signal. Consequences:
- As noted in previous message, there is a bug if the connector is attached to something inside a group, and the group moves or is transformed: the connector won't be notified.
- Using the node-edit tool on an attached object doesn't cause the connector to update. However, interestingly, `Simplify curve' does cause an update. I'll have to look into this.
- When dragging an attached object with the mouse, the connector doesn't update until the mouse is released.
Connectors are represented in XML by a <path> element with attributes inkscape:connection-start and inkscape-connection-end, each with a value of e.g. "#rect1023".
There's no notion of attachment points/magnets as in Dia/Visio/Omnigraffle. We just connect to a point on the bounding box of the attached shape, the point that a line to the object centre would pass through.
(I don't claim that we wouldn't want to support attachment points / magnets, it's just that the current behaviour is better for what I'm using connectors for.)
Simple test case appended. Uses rectangles, so try to use CVS later than 2004-08-16 01:03 +0000.
