I am trying to create a customized marker view. In this view I want to restrict/filter the resources to selected project only. This project name will be supplied dynamically.
For e.g, in the context menu from project explorer, the user will be given option to open the Custom Marker View.
If the user chooses the Custom Marker View from project1, the view should show only the markers of the project1.
Any suggestions?
I've done something similar. At first define a View in your plugin.xml the corresponding class must extend MarkerSupportView. Something like this:
public class MarkerView extends MarkerSupportView {
public MarkerView() {
super("com.example.markerEventContentGenerator"); //$NON-NLS-1$
}
}
Then you need to define the columns in your new view and what kind of markers have to be shown. Here is an example from plugin.xml.
<extension
point="org.eclipse.ui.ide.markerSupport">
<markerContentGenerator
id="com.example.markerEventContentGenerator"
name="Custom Marker View">
<markerTypeReference
id="com.example.myMarker"/>
</markerContentGenerator>
<markerField
class="com.example.fields.NameMarkerField"
id="com.example.field.name"
name="Name">
</markerField>
</extension>
The NameMarkerField class must extend MarkerField. Another dummy example:
public class AnnotationNameMarkerField extends MarkerField {
public AnnotationNameMarkerField() {
super();
}
#Override
public String getValue(final MarkerItem item) {
return "Dummy Name";
}
/*
* (non-Javadoc)
*
* #see
* org.eclipse.ui.views.markers.MarkerField#getDefaultColumnWidth(org.eclipse
* .swt.widgets.Control)
*/
#Override
public int getDefaultColumnWidth(final Control control) {
return 400;
}
}
Now you have to decide how to create your project specific markers with id="com.example.myMarker".

I have an ObservableList of model items. The model item is enabled for property binding (the setter fires a property changed event). The list is the content provider to a TableViewer which allows cell editing. I also intend to add a way of adding new rows (model items) via the TableViewer so the number of items in the list may vary with time.
So far, so good.
As this is all within an eclipse editor, I would like to know when the model gets changed. I just need one changed event from any changed model item in order to set the editor 'dirty'. I guess I could attach some kind of listener to each individual list item object but I wonder if there is a clever way to do it.
I think that I might have a solution. The following class is an inline Text editor. Changes to the model bean (all instances) are picked up using the listener added in doCreateElementObservable. My eclipse editor just needs to add its' own change listener to be kept informed.
public class InlineEditingSupport extends ObservableValueEditingSupport
{
private CellEditor cellEditor;
private String property;
private DataBindingContext dbc;
IChangeListener changeListener = new IChangeListener()
{
#Override
public void handleChange(ChangeEvent event)
{
for (ITableEditorChangeListener listener : listenersChange)
{
listener.changed();
}
}
};
public InlineEditingSupport(ColumnViewer viewer, DataBindingContext dbc, String property)
{
super(viewer, dbc);
cellEditor = new TextCellEditor((Composite) viewer.getControl());
this.property = property;
this.dbc = dbc;
}
protected CellEditor getCellEditor(Object element)
{
return cellEditor;
}
#Override
protected IObservableValue doCreateCellEditorObservable(CellEditor cellEditor)
{
return SWTObservables.observeText(cellEditor.getControl(), SWT.Modify);
}
#Override
protected IObservableValue doCreateElementObservable(Object element, ViewerCell cell)
{
IObservableValue value = BeansObservables.observeValue(element, property);
value.addChangeListener(changeListener); // ADD THIS LINE TO GET CHANGE EVENTS
return value;
}
private List<ITableEditorChangeListener> listenersChange = new ArrayList<ITableEditorChangeListener>();
public void addChangeListener(ITableEditorChangeListener listener)
{
listenersChange.remove(listener);
listenersChange.add(listener);
}
public void removeChangeListener(ITableEditorChangeListener listener)
{
listenersChange.remove(listener);
}
}
Im using GWTP, working on their tab panel example. My issue is i need to demonstrate taking a search term and adding a new tab to the tab panel with the search results. So if i search 5 times, i have 5 tabs. easy enough, so i thought.
Gin is used extensively in GWTP. So my method to add a new tab, which should be something as simple as
tabPanel.addTab(new SearchDataGridView(), NameTokens.searchPage + 1);
gets confusing because of the constructor for the SearchDataGridView class
#Inject
SearchDataGridView(Binder uiBinder) {
employeeDataProvider = new ListDataProvider<Employee>();
initSearchGrid();
initWidget(uiBinder.createAndBindUi(this));
}
yea, i know im not passing the search term yet, im still trying to get the tab to open.
My gin config is this
bindPresenter(
SearchDataGridPresenter.class,
SearchDataGridPresenter.MyView.class,
SearchDataGridView.class,
SearchDataGridPresenter.MyProxy.class);
The gwtp gin config
#Override
protected void configure() {
// RestDispatchAsyncModule.Builder dispatchBuilder = new RestDispatchAsyncModule.Builder();
// install(dispatchBuilder.build());
// install(new RestDispatchAsyncModule.Builder().build());
install(new DefaultModule(DefaultPlaceManager.class));
install(new ApplicationModule());
bind(CurrentUser.class).in(Singleton.class);
bind(IsAdminGatekeeper.class).in(Singleton.class);
// DefaultPlaceManager Constants
bindConstant().annotatedWith(DefaultPlace.class).to(NameTokens.homeNewsPage);
bindConstant().annotatedWith(ErrorPlace.class).to(NameTokens.homeNewsPage);
bindConstant().annotatedWith(UnauthorizedPlace.class).to(NameTokens.homeNewsPage);
bindConstant().annotatedWith(Names.named("rest")).to("http://localhost/services");
// Google Analytics
// bindConstant().annotatedWith(GaAccount.class).to("UA-8319339-6");
// Load and inject CSS resources
bind(ResourceLoader.class).asEagerSingleton();
}
How do i pull this off?
thanks
Using comments below, sorta got it working. The problem is i can't get the contents of the tab to display. I added debugging code to the setInSlot method of my SearchContainer class and realized that whenever i click the search tab, it fires this setInSlot method, but its fired with my default page presenter listed as content.
#Override
public void setInSlot(Object slot, IsWidget content) {
Window.alert("fired setInSlot: " + slot.toString());
Window.alert("fired setInSlot: " + content.toString());
if (slot == ApplicationPresenter.TYPE_SetTabContent) {
tabPanel.setPanelContent(content);
} else {
super.setInSlot(slot, content);
}
}
Thats the method im using to get my info. Its weird that the tab appears properly, the jsonRPC calls that are built into the view are executed properly, it just doesn't display.
My main container presenter has its view and proxy identified by this
public class ApplicationPresenter
extends
TabContainerPresenter<ApplicationPresenter.MyView, ApplicationPresenter.MyProxy> implements
CurrentUserChangedHandler, AsyncCallStartHandler, AsyncCallFailHandler, AsyncCallSucceedHandler,
ApplicationUiHandler {
/**
* {#link ApplicationPresenter}'s proxy.
*/
#ProxyStandard
public interface MyProxy extends Proxy<ApplicationPresenter> {
}
/**
* {#link ApplicationPresenter}'s view.
*/
public interface MyView extends TabView, HasUiHandlers<ApplicationUiHandler> {
void refreshTabs();
void setTopMessage(String string);
}
Could my issue be with my content type? Here is what i have defined for all my types
/**
* This will be the event sent to our "unknown" child presenters, in order for them to register their tabs.
*/
#RequestTabs
public static final Type<RequestTabsHandler> TYPE_RequestTabs = new Type<RequestTabsHandler>();
/**
* Fired by child proxie's when their tab content is changed.
*/
#ChangeTab
public static final Type<ChangeTabHandler> TYPE_ChangeTab = new Type<ChangeTabHandler>();
/**
* Use this in leaf presenters, inside their {#link #revealInParent} method.
*/
#ContentSlot
public static final Type<RevealContentHandler<?>> TYPE_SetTabContent = new Type<RevealContentHandler<?>>();
The proper way to do this is to use a PresenterWidget and a Provider.
In your ClientModule you define this:
bindPresenterWidget(SearchDataGridPresenter.class, SearchDataGridPresenter.MyView.class, SearchDataGridView.class);
In your Presenter that adds the SearchDataGridView you inject a Provider:
#Inject
public SeachContainerPresenter(final Provider<SearchDataGridPresenter> seachDataGridProvider) {
}
For each search you call addToSlot(TYPE_SetSearchDataGridContent,seachDataGridProvider.get()) in your SearchContainerPresenter.
In the SearchContainerView you override the addToSlot() method:
#Override
public void addToSlot(Object slot,Widget content) {
if (slot == SeachContainerPresenter.TYPE_SetSearchDataGridContent) {
tabPanel.addTab(content, NameTokens.searchPage + 1);
}
else {
super.addToSlot(slot,content);
}
}
Look in binding everything together. I think that you have to add the AsyncProvider of your presenter to yuor Ginjector.
AsyncProvider<SearchDataGridPresenter> getSearchDataGridPresenter();
You can put a SearchDataGridView getSearchDataGridView() method in the GIN Injector and call it in order to obtain the SearchDataGridView instance.
I am looking for a solution to make this tree selection editable in the package explorer view itself.
the idea
for example- if we click rename on any class in package explorer, it will prompt a new window to rename. This functionality is same for any class that implement TreeSelection Class.
But the Solution i am looking for is - when rename is invoked, the rename option is shown at the tree itself (like we have in Windows Explorer view)
any suggestion on how to attain this behavior on eclipse.
You don't need to have some special editable selection, you just want to make the tree editable. For this you use EditingSupport, like this (adapted from http://www.vogella.com/articles/EclipseJFaceTableAdvanced/article.html#jfacetable_editor):
public class NameEditingSupport extends EditingSupport {
private final TreeViewer viewer;
public FirstNameEditingSupport(TreeViewer viewer) {
super(viewer);
this.viewer = viewer;
}
#Override
protected CellEditor getCellEditor(Object element) {
return new TextCellEditor(viewer.getTree());
}
#Override
protected boolean canEdit(Object element) {
return true;
}
#Override
protected Object getValue(Object element) {
// return the name
}
#Override
protected void setValue(Object element, Object value) {
// update the name of your object
viewer.update(element, null);
}
}
// in the code creating the tree
treeViewer.setEditingSupport(new NameEditingSupport(treeViewer));
I am working on eclipse plugin that will allow a java bean to be dragged onto jsp file then on the drop event some code generators will be called.
I'm attempting to use the extension point "org.eclipse.ui.dropActions" but drag and drop listeners never get called .Is there any way to attach drag and drop listener to IFile object.
Am I on the right track with the DropActionDelegate?
Code:
DragListener
class DragListener implements DragSourceListener {
#Override
public void dragFinished(DragSourceEvent event) {
System.out.println("Finish");
}
#Override
public void dragSetData(DragSourceEvent event) {
PluginTransferData p;
p = new PluginTransferData (
"dream_action", // must be id of registered drop action
"some_data".getBytes() // may be of arbitrary type
);
event.data = p;
}
#Override
public void dragStart(DragSourceEvent event) {
// TODO Auto-generated method stub
System.out.println("Start");
}
}
DropActionDelegate
class DropActionDelegate implements IDropActionDelegate {
#Override
public boolean run(Object source, Object target) {
String Data= (String) target;
return true;
}
}
Plugin.xml
<extension point="org.eclipse.ui.dropActions">
<action
id="dream_action"
class="newdreamfileplugin.wizards.DropActionDelegate">
</action>
</extension>
Thanks.
Solved it.Finally i created my own navigator using org.eclipse.ui.navigator.navigatorContent extension which have a property dropAssistant.
I use ListEditor to allow editing list of chilren and I do everything just like I saw in some examples.The only difference from examples is that I want widgets editing children to be added as a tabs to some TabLayoutPanel.
The problem is that I want to give a header to this new tab and this header is not constant but depends on object being edited by newly created sub-editor (so let the header be child.getName()) which I don't know inside EditorSource#create() method.
ListEditor<ChildProxy, ChildPanel> children = ListEditor
.of(new EditorSource<ChildPanel>() {
#Override
public ChildPanel create(int index) {
ChildPanel tab = new ChildPanel();
//here's a problem, how I can get tabHeader here?
tabPanel.add(tab,tabHeader);
}
});
How can I set value-dependent headers to tabs created by create()? Any help/workaround would be greatly appreciated.
Does this approach work for you :
public class ChildrenEditor extends Composite implements
IsEditor<ListEditor<Child, ChildInTabEditor>> {
ListEditor<Child, ChildInTabEditor> editor;
public ChildrenEditor() {
initWidget(uiBinder.createAndBindUi(this));
editor = ListEditor.of(new ChildInTabEditorSource());
}
private class ChildInTabEditorSource extends EditorSource<ChildInTabEditor> {
public ChildInTabEditor create(int index) {
ChildInTabEditor tab = new ChildInTabEditor();
// here's the trick :
Child child = editor.getList().get(index);
tabPanel.add(tab,child.getTabTitle());
return tab;
}
}
#Override
public ListEditor<Child, ChildInTabEditor> asEditor() {
return editor;
}
}
ChildInTabEditor must be a Tab that implements Editor<Child> then too!
What worked for me was passing tabPanel and index to newly created ChildPanel() and make it ValueAwareEditor. Then on setValue() I was setting header on tabPanel reference at given index.
