嗨，我实现了“org.eclipse.core.runtime”的 IProgressMonitor 和 SubProgressMonitor。进度监视器正在工作，但我的问题是它没有像我想要的那样显示进度。在完成之前它没有显示任何进展。我会给你代码示例。
try {
PlatformUI.getWorkbench().getProgressService().
busyCursorWhile(new IRunnableWithProgress() {
@Override
public void run(IProgressMonitor monitor) throws InvocationTargetException,
InterruptedException {
// TODO Auto-generated method stub
try{
monitor.beginTask("Operation in Progress...", ticks);
for(int i = 0; i < getCompilationUnit().size(); i++){
try {
IType type = getCompilationUnit().get(i).findPrimaryType();
IType[] types = getCompilationUnit().get(i).getTypes();
if(monitor.isCanceled())
throw new OperationCanceledException();
updateListPrimaryType(type, totalNumberOfCode, types);
monitor.worked(1/ticks);
IMethod[] method = type.getMethods();
int work = method.length;
updateListIMethod(method);
monitor.worked(1/ticks);
updateListMethodAttributeMember(type,new SubProgressMonitor(monitor, (1/ticks)));
updateListMember(type,types);
monitor.worked(1/ticks);
} catch (JavaModelException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}finally{
monitor.done();
}
}
});
这是方法 updateListMethodAttributeMember 的代码：
private void updateListMethodAttributeMember(IType type,SubProgressMonitor subProgressMonitor) {
// TODO Auto-generated method stub
ClassList tmp;
try{
IMethod[] method = type.getMethods();
IField[] field = type.getFields();
subProgressMonitor.beginTask("Operation in Progress...", method.length);
for(int m = 0; m < method.length; m++){
String methodName = getSubstringName(method[m].toString());
IMethod met = method[m];
tmp = new ClassList(className, methodName, path);
if(!met.isConstructor() || !met.isMainMethod()){
try {
int number = performIMethodSearch(met);
tmp.setNumberOfCalls(number);
} catch (CoreException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
subProgressMonitor.worked(1/method.length);
getMethodClassList().add(tmp);
}
for(int f = 0; f < field.length; f++){
String attributeName = getSubstringName(field[f].toString());
tmp = new ClassList(className, attributeName, path);
String parent = field[f].getParent().getElementName().toString();
String description = "Parent Class: " + parent;
tmp.setDataDescription(description);
getAttributeClassList().add(tmp);
}
} catch (JavaModelException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}finally{
subProgressMonitor.done();
}
}
