hi there,
i am developing a java application that opens a cml or com file and i want
it to show this file in a jmol viewer.
i added all jar files that belongs jmol into a project library, then i added
all source files into source package of that project. then i added that
project into my main project.
now i am trying to add jmolpanel into a JPanel and make it work but i got
""AWT-EventQueue-0" java.lang.NullPointerException" error all the time.
i use this method and call this when user opens a file :
public void JmolView(){
JmolPanel jmolPanel = new JmolPanel();
Jview.add(jmolPanel); // Jview is my JPanel
JmolSimpleViewer viewer = jmolPanel.getViewer();
viewer.evalString("zap");
viewer.openFile(JName);
jmolPanel.setVisible(true);
}
and my jmol class :
static class JmolPanel extends JPanel {
JmolSimpleViewer viewer ;
JmolAdapter adapter;
JmolPanel() {
adapter = new SmarterJmolAdapter();
viewer = JmolSimpleViewer.allocateSimpleViewer(this, adapter);
}
public JmolSimpleViewer getViewer() {
return viewer;
}
final Dimension currentSize = new Dimension();
final Rectangle rectClip = new Rectangle();
public void paint(Graphics g) {
getSize(currentSize);
g.getClipBounds(rectClip);
viewer.renderScreenImage(g, currentSize, rectClip);
}
}
and errors :
