insert a rect into JSVGCanvas
Hi, i must to insert a rect into JSVGCanvas. This is the code that i wrote
but it doesn't nothing:
private JButton getProva() {
if (prova == null) {
prova = new JButton();
prova.setBounds(new Rectangle(446, 13, 110, 35));
prova.setText("pro");
prova.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent e) {
SVGDocument doc = JSVGCanvas.getSVGDocument();
SVGElement svgRoot = doc.getRootElement();
JSVGCanvas.setDocument(doc);
String svgNS = "http://www.w3.org/2000/svg";
Element elem = doc.createElementNS(svgNS, "rect");
elem.setAttributeNS(null, "id", "bgrectangle");
elem.setAttributeNS(null, "x", "200");
elem.setAttributeNS(null, "y", "100");
elem.setAttributeNS(null, "width", "100%");
elem.setAttributeNS(null, "height", "100%");
elem.setAttributeNS(null, "pointer-events", "fill");
elem.setAttributeNS(null, "style", "fill:none;stroke:none");
svgRoot.appendChild(elem);
}
});
}
return prova;
}
"prova" is a JButton...

Hi Peppe.
Peppe:
> Hi, i must to insert a rect into JSVGCanvas. This is the code that i wrote

When you set the document to be shown with .setDocument(doc), it is
asynchronously parsed and rendered. You should wait until the document
has been built before performing the update. See:
http://xmlgraphics.apache.org/batik/svgcanvas.html#eventhandling
When performing the DOM modification in response to this event, you
should schedule it to be done in the canvas’ update thread. See:
http://xmlgraphics.apache.org/batik/javaScripting.html#Threads
Alternatively, if you only make modifications once, initially, you could
do them before the call to setDocument.

Then the bug I mentioned can't be affecting you. There is likely a bug
in your code, I've looked over your code and it isn't obvious to me.
I would suggest adding println's to print the 'id' of the element that
is clicked on, to print the transform before you set it, etc...
Good luck.

I use the last version of Batik, version 1.6. Perhaps i wrong something in
file loading?...see my post "appendchild, error?"...thanks

Hmm, what Batik are you using? Trunk? If so you might be
hitting a recently introduced bug in the animated transform support.
You might try 'batik/branches/svg11' which is more stable but
less feature right (most notably it lacks sXBL and animation
support).

RE: insert a rect into JSVGCanvas
Posted by "Bishop, Michael W. CONTR J9C880" <Mi...@je.jfcom.mil>.
The short answer is yes. You'd record the point on mousePressed, record the point on mouseReleased and then transform them from screen coordinates to document coordinates and render the rectangle accordingly.

RE: insert a rect into JSVGCanvas
Posted by Peppe <pe...@gmail.com>.
This is the code where i load the svg image:
private JButton getJButton() {
if (jButton == null) {
jButton = new JButton();
jButton.setBounds(new Rectangle(10, 5, 59, 28));
jButton.setText("load");
jButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
JFileChooser fc = new JFileChooser(".");
int choice = fc.showOpenDialog(panel);
if (choice == JFileChooser.APPROVE_OPTION) {
File f = fc.getSelectedFile();
try{
JSVGCanvas.setURI(f.toURL().toString()); //carica
l'immagine dal file all'interno del canvas
//JSVGCanvas listener
JSVGCanvas.addSVGDocumentLoaderListener(new
SVGDocumentLoaderAdapter() {
public void
documentLoadingStarted(SVGDocumentLoaderEvent e) {
label.setText("Caricamento immagine...");
}
public void
documentLoadingCompleted(SVGDocumentLoaderEvent e) {
label.setText("Immagine caricata");
}
});
JSVGCanvas.addGVTTreeBuilderListener(new
GVTTreeBuilderAdapter() {
public void gvtBuildStarted(GVTTreeBuilderEvent
e) {
label.setText("Build Started...");
}
public void
gvtBuildCompleted(GVTTreeBuilderEvent e) {
label.setText("Build Done.");
}
});
JSVGCanvas.addGVTTreeRendererListener(new
GVTTreeRendererAdapter() {
public void
gvtRenderingPrepare(GVTTreeRendererEvent e) {
label.setText("Rendering Started...");
}
public void
gvtRenderingCompleted(GVTTreeRendererEvent e) {
label.setText("");
}
});
}catch(IOException error){
error.printStackTrace();
}
}
}
});
}
return jButton;
}
when i press JButton "prova" my console shows this error:

Hi Peppe,
I noticed a few things that look problematic in your example.
First I don't see where you load the base document. In which case
getDocument()

So this would return null.

You should not call 'setDocument'.

Isn't 'pt2d' null here? You null it out above and I don't see where
you assign it.
All of which leads me to believe that you are not looking at the
error messages the JVM is spitting out. I understand you are running
in an Applet but usually there is a way to show the error log from
the browser.

Set the JSVGCanvas's state to ALWAYS_DYNAMIC and run the code that modifies
the document in the JSVGCanvas's RunnableQueue.
Michael Bishop
Thank you for your answers, i modified code in this way but it doesn't
works....sorry but it's my first time that i use batik:
//This code is wrote in a JApplet class
private JSVGCanvas getJSVGCanvas() {
if (JSVGCanvas == null) {
JSVGCanvas = new JSVGCanvas();
JSVGCanvas.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC);
JSVGCanvas.setBounds(new Rectangle(114, 54, 476, 333));
JSVGCanvas.getInteractors().add(rotateInteractor);
JSVGCanvas.getInteractors().add(zoomInteractor);
}
return JSVGCanvas;
}
private JButton getProva() {
if (prova == null) {
prova = new JButton();
prova.setBounds(new Rectangle(446, 13, 110, 35));
prova.setText("pro");
prova.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent e) {
JSVGCanvas.getUpdateManager().getUpdateRunnableQueue().invokeLater(new
Runnable() {
public void run() {
SVGDocument doc = JSVGCanvas.getSVGDocument();
Point2D pt2d = null;
SVGElement svgRoot = doc.getRootElement();
JSVGCanvas.setDocument(doc);
String svgNS = "http://www.w3.org/2000/svg";
Element elem = doc.createElementNS(svgNS, "rect");
elem.setAttributeNS(null, "id", "bgrectangle");
elem.setAttributeNS(null, "x",""+pt2d.getX());
elem.setAttributeNS(null, "y",""+pt2d.getY());
elem.setAttributeNS(null, "width", "100%");
elem.setAttributeNS(null, "height", "100%");
elem.setAttributeNS(null, "pointer-events", "fill");
elem.setAttributeNS(null, "style", "fill:none;stroke:none");
svgRoot.appendChild(elem);
}
});
JSVGCanvas.repaint();
}
});
}
return prova;
}

Subject: insert a rect into JSVGCanvas
Hi, i must to insert a rect into JSVGCanvas. This is the code that i wrote
but it doesn't nothing:
private JButton getProva() {
if (prova == null) {
prova = new JButton();
prova.setBounds(new Rectangle(446, 13, 110, 35));
prova.setText("pro");
prova.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent e) {
SVGDocument doc = JSVGCanvas.getSVGDocument();
SVGElement svgRoot = doc.getRootElement();
JSVGCanvas.setDocument(doc);
String svgNS = "http://www.w3.org/2000/svg";
Element elem = doc.createElementNS(svgNS, "rect");
elem.setAttributeNS(null, "id", "bgrectangle");
elem.setAttributeNS(null, "x", "200");
elem.setAttributeNS(null, "y", "100");
elem.setAttributeNS(null, "width", "100%");
elem.setAttributeNS(null, "height", "100%");
elem.setAttributeNS(null, "pointer-events", "fill");
elem.setAttributeNS(null, "style", "fill:none;stroke:none");
svgRoot.appendChild(elem);
}
});
}
return prova;
}
"prova" is a JButton...
