I have developed an eclipse plugin based on GEF. When I change the properties, I need to close all files and open them manually.
How can I refresh the instances of my plugin after changing properties?
public class MyPreferencePage extends FieldEditorPreferencePage implements IWorkbenchPreferencePage {
public MyPreferencePage() {
super(GRID);
}
public void createFieldEditors() {
addField(new StringFieldEditor(PreferenceConstants.MY_CONF,
"Label", getFieldEditorParent()));
}
public void init(IWorkbench workbench) {
setPreferenceStoreMyEditorPlugin.getDefault().getPreferenceStore());
}
#Override
public boolean performOk() {
boolean res = super.performOk();
// Validated input
// I think I have to refresh the config here
return res;
}
}
You can add a listener to your preference store which will be told about changes to preferences using:
MyEditorPlugin.getDefault().getPreferenceStore().addPropertyChangeListener(listener);
where listener is an implementation of org.eclipse.jface.util.IPropertyChangeListener. The single method in this interface is
public void propertyChange(PropertyChangeEvent event)
{
String changedPropertyId = event.getProperty();
// TODO check if you need to do something for the changed property
}

I added a control in the toolbar which extends WorkbenchWindowControlContribution and implements ISelectionProvider. This control contains a Combo and when I change the selection I want to notify another view. Because it's not a ViewPart I can't call getSite().setSelectionProvider directly. I tried to set it like this:
PlatformUI.getWorkbench().getDisplay().asyncExec(() -> {
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().getActivePart().getSite().setSelectionProvider(MyControl.this);
});
If I add this to the protected Control createControl(Composite parent) method the getActivePart would always be null. I also tried registering it when the Combo's value changes for the first time, but that way my other View wasn't notified about the change event.
Here is the ISelectionProvider methods:
#Override
public void addSelectionChangedListener(ISelectionChangedListener listener) {
listeners.add(listener);
}
#Override
public ISelection getSelection() {
return new StructuredSelection(comboBox.getText());
}
#Override
public void removeSelectionChangedListener(ISelectionChangedListener listener) {
listeners.remove(listener);
}
#Override
public void setSelection(ISelection selection) {
for (ISelectionChangedListener listener : listeners) {
listener.selectionChanged(new SelectionChangedEvent(this, selection));
}
}
The View that should be getting notified implements ISelectionListener. I register it in the public void createPartControl(Composite parent) with getSite().getPage().addSelectionListener(this);
And here is the override of the SelectionChanged too:
#Override
public void selectionChanged(IWorkbenchPart part, ISelection selection) {
if (part instanceof MyControl) {
String selectedProtocol = ((StructuredSelection) selection).getFirstElement().toString();
}
}
Can it be done?
Thanks!
I have custom class InternalTimerServiceController in my application. I want to use it in another class inside android annotations. And it seems that autocompletion does not work correctly in this case.
I have this interface
public interface InternalTimerServiceControllerContract
{
void doWork();
}
And this class
#EBean
public class InternalTimerServiceController implements InternalTimerServiceControllerContract
{
#Override
public void doWork()
{
// do work
}
}
And this is my Activity
public class MyActivity extends Activity
{
// try uncomment line below and see if autocomplete works properly
//#Bean(Internal)
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
It's a bug, thanks for reporting. I've created a ticket for it: http://youtrack.jetbrains.com/issue/IDEA-98298
I have a custom RCP application,
Do you know how to hide the Installation Details button from the About Dialog ??
I haven't found the way to hide that button, I think the only possibility is to extend AboutDialog and make a new command for your plugin.
public class DAboutHandler extends AbstractHandler {
private class DAboutDialog extends AboutDialog
{
public final static int DETAILS_ID = IDialogConstants.CLIENT_ID + 1;
public DAboutDialog(Shell parentShell) {
super(parentShell);
}
#Override
protected Button createButton(Composite parent, int id, String label, boolean defaultButton) {
if(id==DETAILS_ID) return null;
return super.createButton(parent, id, label, defaultButton);
}
}
/*
* (non-Javadoc)
*
* #see org.eclipse.core.commands.IHandler#execute(org.eclipse.core.commands.ExecutionEvent)
*/
public DAboutDialog execute(ExecutionEvent event) throws ExecutionException {
new DAboutDialog(HandlerUtil.getActiveShellChecked(event)).open();
return null;
}
}
I don't think you can ... the Installation Details button is created in the AboutDialog createButtonsForButtonBar method ... and it looks like it's unconditional.
i have created a sample view in eclipse using the following code.i want the view to be
automatically refereshed.the part of code in quotes "" gives refresh option but it is done
manually.can anyone help me know how it can be done automatically
public class SampleView extends ViewPart {
public static final String ID = "tab.views.SampleView";
private TableViewer viewer;
class ViewContentProvider implements IStructuredContentProvider {
public void inputChanged(Viewer v, Object oldInput, Object newInput) {
}
public void dispose() {
}
public Object[] getElements(Object parent) {
return new String[] { "Status of your hudson build is: " +hudson.d};
}
}
class ViewLabelProvider extends LabelProvider implements ITableLabelProvider {
public String getColumnText(Object obj, int index) {
return getText(obj);
}
public Image getColumnImage(Object obj, int index) {
return getImage(obj);
}
public Image getImage(Object obj) {
return PlatformUI.getWorkbench().
getSharedImages().getImage(ISharedImages.IMG_OBJ_ADD);
}
}
public SampleView() {
}
public void createPartControl(Composite parent) {
viewer = new TableViewer(parent, SWT.MULTI | SWT.H_SCROLL | SWT.V_SCROLL);
viewer.setContentProvider(new ViewContentProvider());
viewer.setLabelProvider(new ViewLabelProvider());
viewer.setInput(getViewSite());
PlatformUI.getWorkbench().getHelpSystem().setHelp(viewer.getControl(), "Tab.viewer");
hookContextMenu();
}
" private void hookContextMenu() {
MenuManager menuMgr = new MenuManager("#PopupMenu");
Menu menu = menuMgr.createContextMenu(viewer.getControl());
viewer.getControl().setMenu(menu);
Action refresh =new Action() {
public void run() {
// initialize();
viewer.refresh();
}
};
refresh.setText("Refresh");
menuMgr.add(refresh);
}"
public void setFocus() {
viewer.getControl().setFocus();
}
}
It is only possible to refresh the tree contents automatically, if you fill it using JFace Data Binding, that would not work with remote build results.
I recommend either using a model with notification support: when the model changes, its listeners are notified. Then your view could listen for these notifications and refresh itself.
If for some reason this is not possible, you have to poll your models manually. For that I recommend creating a Job that is executed in the background automatically (its last step is to reschedule itself some times later), that checks whether the model changed and refreshes the view.
I have a view which would like to be notified about all the currently opened editors. Where can I add a listener to achieve this?
I was expecting WorkbenchPage or EditorManager to have some appropriate listener registry, but I couldn't find it.
Does your view uses a org.eclipse.ui.IPartListener2 ?
That is what is using this EditorListener, whose job is to react, for a given view, to Editor events (including open and close)
public class EditorListener implements ISelectionListener, IFileBufferListener,
IPartListener2 {
protected BytecodeOutlineView view;
EditorListener(BytecodeOutlineView view){
this.view = view;
}
[...]
/**
* #see org.eclipse.ui.IPartListener2#partOpened(org.eclipse.ui.IWorkbenchPartReference)
*/
public void partOpened(IWorkbenchPartReference partRef) {
view.handlePartVisible(partRef.getPart(false));
}
Now if your ViewPart directly implements an IPartListener2, it can register itself to the various Editors, like this BytecodeReferenceView
public class BytecodeReferenceView extends ViewPart implements IPartListener2, ISelectionListener {
[...]
public void createPartControl(Composite parent) {
browser = new Browser(parent, SWT.BORDER);
browser.setText(BytecodeOutlinePlugin.getResourceString(NLS_PREFIX
+ "empty.selection.text"));
final IWorkbenchWindow workbenchWindow = getSite().getWorkbenchWindow();
workbenchWindow.getPartService().addPartListener(this);
[...]
I think you're on the right track. You need to listen to the IWorkbenchPage IPartService events:
page.addPartListener(new IPartListener() {
partOpened(IWorkbenchPart part) {
...
}
...
});
