Examples of pl.tecna.gwt.connectors.client.elements.Connector.showOnDiagram()

pl.tecna.gwt.connectors.client.elements.Connector.showOnDiagram()

Calculates positions of Connector's sections and shows Connector on a given panel. The Connector is represented by horizontal or vertical lines which are {@link Section}s. The panel argument's type must be AbsolutePanel.

This method also add all necessary {@link Point}s: {@link EndPoint}s at the beginning and at the end of the Connector and {@link CornerPoint}s at the Connector's corners.

The way sections are generated:
Let "width" a width of rectangle drown on connectors start point and end point
Let "height" a height of rectangle drown on connectors start point and end point
If ("width" < "height") the connection contains two vertical sections and one horizontal section.
If ("height" < "width") the connection contains two horizontal sections and one vertical section. @param diagram a Diagram the Connector will be added to
