Hello Everybody,
Thanks for all your help. I have a little problem when i try to open the
view of my plugin. I have the following view class. The intention is to
create a view with a label and i set the text of the view to just the name
of a SimpleName element. This is the class:
public class TableView extends ViewPart{
public TableView(){
}
public void createPartControl(Composite parent){
GridLayout gridLayout = new GridLayout();
parent.setLayout(gridLayout);
Label label = new Label(parent, SWT.CENTER);
ICompilationUnit icomp = this.findProject();
CompilationUnit comp = this.parse(icomp);
SimpleName sn =
((TypeDeclaration)comp.types().get(0)).getName();
label.setText(sn.getFullyQualifiedName());
}
public void setFocus(){
}
protected CompilationUnit parse(ICompilationUnit unit) {
ASTParser parser = ASTParser.newParser(AST.JLS3);
parser.setKind(ASTParser.K_COMPILATION_UNIT);
parser.setSource(unit); // set source
parser.setResolveBindings(true); // we need bindings later on
return (CompilationUnit)parser.createAST(null /* IProgressMonitor
*/); // parse
}
public ICompilationUnit findProject(){
IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot();
// "org.integ.proj.sl" is the project name
IProject project = root.getProject("org.integ.proj.sl");
if (project.exists() && !project.isOpen())
try {
project.open(null /* IProgressMonitor */);
} catch (CoreException e1) {
e1.printStackTrace();
}
IJavaProject javaProject = JavaCore.create(project);
IType lwType = null;
try {
// "Menu" is a class in the "org.integ.proj.sl.gui" package
lwType = javaProject.findType("org.integ.proj.sl.gui.Menu");
} catch (JavaModelException e) {
e.printStackTrace();
}
ICompilationUnit lwCompilationUnit =
lwType.getCompilationUnit();
return lwCompilationUnit;
}
}
After i execute the project as "Eclipse Application", i get a new
workspace and when i try to open the view, i get the following errors and
exception:
Error creating the view
