OK, I figured out this call hierarchy for
* execute() (in AbstractPlugIn.toActionListener()) and
* run() (in TaskWrapper.run()).
=== FeatureInstaller.addMainMenuItem() ===
public void addMainMenuItem(PlugIn executable, String[] menuPath,
String menuItemName, boolean checkBox, Icon icon, EnableCheck
enableCheck) {}
=== FeatureInstaller.associate() ===
private void associate(JMenuItem menuItem, PlugIn plugIn) {
menuItem.addActionListener(AbstractPlugIn.toActionListener(plugIn,
workbenchContext, taskMonitorManager));
}
=== AbstractPlugIn.toActionListener() ===
boolean executeComplete = plugIn.execute(plugInContext);
if (plugIn instanceof ThreadedPlugIn && executeComplete) {
taskMonitorManager.execute((ThreadedPlugIn) plugIn, plugInContext);
}
=== TaskMonitorManager.execute() ===
final TaskWrapper taskWrapper = new TaskWrapper(plugIn, context,
progressDialog);
=== TaskWrapper.run() ===
plugIn.run(dialog, context);
