Hi,
I have the following. A class McPanel which extends JSVGScrollPane.
I also have a method loadImage(String fileName) which uses canvas.setURI,
the problem is I want this method to wait until the document has been
rendered. I have tried with a flag, as can be seen in the code below, but it
doesn't work. Any suggestions?
public class McPanel extends JSVGScrollPane implements EventListener,
ActionListener {
// Indicate whether the image has already been loaded
boolean imageLoaded = false;
public McPanel(EquipView aCreator) {
super(new JSVGCanvas());
canvas.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC);
// Set the JSVGCanvas listeners.
canvas.addSVGDocumentLoaderListener(new
SVGDocumentLoaderAdapter() {
public void
documentLoadingStarted(SVGDocumentLoaderEvent e) {
System.out.println("Document Loading...");
}
public void
documentLoadingCompleted(SVGDocumentLoaderEvent e) {
System.out.println("Document Loaded.");
}
});
canvas.addGVTTreeBuilderListener(new GVTTreeBuilderAdapter() {
public void gvtBuildStarted(GVTTreeBuilderEvent e) {
System.out.println("Build Started...");
}
public void gvtBuildCompleted(GVTTreeBuilderEvent e) {
System.out.println("Build Done.");
}
});
canvas.addGVTTreeRendererListener(new GVTTreeRendererAdapter() {
public void gvtRenderingPrepare(GVTTreeRendererEvent e)
{
System.out.println("Rendering Started...");
}
public void gvtRenderingCompleted(GVTTreeRendererEvent
e) {
System.out.println("Rendering Done.");
canvas.repaint();
imageLoaded = true;
});
}
public boolean loadImage(String fileName) {
imageLoaded=false;
canvas.setURI(fileName);
while (true) {
if (imageLoaded)
break;
}
return true;
}
Thanks for any help.
Andrej.
