Class TextPart

  • java.lang.Object
    • com.supermap.data.TextPart

  • public class TextPart
extends java.lang.Object
    The TextPart class.

    This class represents the part of the text object, and mainly used to store the information of the text, rotation angle and anchor point etc. of the part of the GeoText.

    The ObjectDisposedException exception will be thrown while invoking the member of this class after being released by the dispose() method.
    Example:
    The following codes demonstrate how to add text child object to text object and display in the map tracking layer. 
     public void textPartTest(){
        // Supposes that you open a workspace object workspace
        // Set the text sub object
        TextPart textPart = new TextPart();
        textPart.setAnchorPoint(new Point2D(500, 500));
        textPart.setRotation(30);
        textPart.setText("Example");

        // Adds the sub object into the text object
        GeoText geotext = new GeoText();
        geotext.addPart(textPart);

        // Initialize the Map object
        Map map = new Map(workspace);

        // Adds the text object into the tracking layer of map and displays it.
        map.getTrackingLayer().add(geotext, "");
        map.setViewBounds(new Rectangle2D(new Point2D(0, 0),new Point2D(300, 300)));

        // Releases the resources
        textPart.dispose();
        geotext.dispose();
        workspace.dispose();
    }
