Raster width and height setting problem

[Tran, Vu Binh]

Hi,

I am having problem setting the raster width and height as
well as erasing raster. I am using the sample code from
Marcus G. Daniels TestPixMap. Whenever I call the
r.SetWidth(200) or r.SetHeight(200) or r.setWidth$Height(200, 200)
or r.erase() I always see the Dr. Watson on Windows says access
violation. The code is as follows


import swarm.Globals;
import swarm.simtoolsgui.GUISwarmImpl;
import swarm.gui.PixmapCImpl;
import swarm.gui.PixmapImpl;
import swarm.gui.PixmapC;
import swarm.gui.Pixmap;
import swarm.gui.Raster;
import swarm.gui.RasterImpl;
import swarm.gui.ColormapImpl;
import swarm.gui.Colormap;
import swarm.defobj.Zone;

public class TestPixmap extends GUISwarmImpl {
    static void main (String args[]) {
        Globals.env.initSwarm
("TestCanvas", "0.0",
"address@hidden",
                              
args);

        TestPixmap testPixmap = new
TestPixmap (Globals.env.globalZone);
       
//System.out.println(Globals.env.arguments.getAppDataPath ());

        testPixmap.buildObjects
();
        testPixmap.buildActions
();
        testPixmap.activateIn
(null);
        testPixmap.go ();
    }

    public TestPixmap (Zone aZone) {
        super (aZone);
    }

    public Object buildObjects () {
        super.buildObjects ();

        Colormap colormap = new
ColormapImpl (getZone ());
        colormap.setColor$ToName
((byte) 0, "blue");

        Raster r = new RasterImpl
(getZone ());
        r.setWindowTitle ("My
raster");

//************************************************************************************
// Problems with these lines
        r.setWidth$Height (200,
200);
        r.setWidth(200);
        r.setHeight(200);
        r.erase ();
//************************************************************************************

        r.setColormap 
(colormap);
        r.pack ();

        PixmapC pixmapC = new
PixmapCImpl (new PixmapImpl ());

        pixmapC.createBegin (getZone
());
        String appDir =
Globals.env.arguments.getAppDataPath ();

        pixmapC.setDirectory
(appDir);
        pixmapC.setFile
("ant.png");
        Pixmap pixmap = (Pixmap)
pixmapC.createEnd ();
        pixmap.setRaster (r);

        pixmap.drawX$Y (50, 50);

        return this;
    }
}
