我正在使用 eclipse 插件开发开发一个向导。
要求:
我必须创建一个上下文菜单,只要用户右键单击 java 项目中的源文件夹,该菜单就需要填充。一旦用户执行了第一步,我的处理程序需要在我的向导中获取选定的 src 文件夹。我的向导包含一个 treeviewer,我需要在其中打包选定的 src 文件夹。
我的分析:
我有我的处理程序类,它获取选定的包
SampleHandler.java
public Object execute(ExecutionEvent event) throws ExecutionException {
shell = HandlerUtil.getActiveShell(event);
// Initializing workbench window object
IWorkbenchWindow window = (IWorkbenchWindow) HandlerUtil.getActiveWorkbenchWindow(event);
ISelection sel = HandlerUtil.getActiveMenuSelection(event);
final IStructuredSelection selection = (IStructuredSelection) sel;
Object firstElement = selection.getFirstElement();
if (firstElement instanceof IPackageFragment) {
// Get the selected fragment
IPackageFragment packageFragment = (IPackageFragment) firstElement;
modelPackage = packageFragment.getElementName();
boolean a =!ProjectResourceHelper.isEntityBasePackage(modelPackage);
if(a == true){
MessageDialog.openInformation(shell, "Warning", "Please click from entity base package");
Shell shell = HandlerUtil.getActiveShell(event);
GreenWizard wizard = new GreenWizard();
WizardDialog dialog = new WizardDialog( part.getSite().getShell(), wizard);
dialog.create();
dialog.open();
return null;
}
try{
window.run(true, true, new IRunnableWithProgress(){
@Override
public void run(IProgressMonitor monitor) throws InvocationTargetException, InterruptedException {
monitor.beginTask("Layer codes are being generated...", 1);
// Invocation of generate layers method
monitor.worked(1);
// Done with operation completion.
monitor.done();
}
});
}
catch(InvocationTargetException ite){
MessageDialog.openError(shell, "Greenfield Code Generation Exception", ite.getMessage());
}
catch (InterruptedException ie) {
MessageDialog.openError(shell, "Greenfield Code Generation Exception", ie.getMessage());
}
}
我有在此方法中调用的主要向导类。
GreenWizard wizard = new GreenWizard();
我的主向导反过来调用我的向导页面,我需要在用户右键单击时执行选择。
我的向导页面类
public GenerateGreenfieldLayer(IWorkbench workbench,
IStructuredSelection selection) {
super("Greenfield");
setImageDescriptor(ResourceManager
.getImageDescriptor("\\icons\\greenfield-new-wiz.png"));
setTitle("GreenField Generate layer");
setDescription("Select specfic class to grenerate Layers");
}
/**
* Create contents of the wizard.
*
* @param parent
*/
@Override
public void createControl(Composite parent) {
Composite container = new Composite(parent, SWT.NULL);
setControl(container);
container.setLayout(new GridLayout(2, false));
final CheckboxTreeViewer treeViewer = new CheckboxTreeViewer(container,
SWT.BORDER);
tree = treeViewer.getTree();
tree.setToolTipText("Choose package");
GridData gd_tree = new GridData(SWT.FILL, SWT.FILL, true, true, 1, 1);
gd_tree.widthHint = 280;
gd_tree.heightHint = 140;
tree.setLayoutData(gd_tree);
treeViewer.setContentProvider(new GreenfieldTreeContentProvider());
treeViewer.setLabelProvider(new WorkbenchLabelProvider());
treeViewer.addSelectionChangedListener(new ISelectionChangedListener () {
public void selectionChanged(SelectionChangedEvent event) {
}
});
}
谁能指导我如何从对象方法中获取选择并在我的向导页面中作为 treeviewer 初始输入传递。
如果我缺少任何步骤,请纠正我,因为我对此很陌生。
