I am doing POC on how global level preferences can be store at Project level as well.
I have created the sample application in which I have created the MyPreferencePage page and used the org.eclipse.ui.preferencePages extension to add this page in eclipse preferences.
I am also able to save the page data and retrieve it using the code setPreferenceStore(Activator.getDefault().getPreferenceStore()).
Now I want to create new page under projects properties level and should able to store page values at project level.
Below is the code for MyPreferencePage and preferencePages extension.
<extension
point="org.eclipse.ui.preferencePages">
<page
class="com.vogella.preference.MyPreferencePage"
id="com.vogella.preference.page1"
name="MyPreferencePage">
</page>
</extension>
public class MyPreferencePage extends FieldEditorPreferencePage implements
IWorkbenchPreferencePage {
public MyPreferencePage() {
super(GRID);
}
#Override
public void createFieldEditors() {
addField(new DirectoryFieldEditor(PreferenceConstants.P_PATH,
"&Directory preference:", getFieldEditorParent()));
addField(new BooleanFieldEditor(PreferenceConstants.P_BOOLEAN,
"&An example of a boolean preference", getFieldEditorParent()));
addField(new RadioGroupFieldEditor(PreferenceConstants.P_CHOICE,
"An example of a multiple-choice preference", 1,
new String[][] { { "&Choice 1", "choice1" },
{ "C&hoice 2", "choice2" } }, getFieldEditorParent()));
addField(new StringFieldEditor(PreferenceConstants.P_STRING,
"A &text preference:", getFieldEditorParent()));
addField(new StringFieldEditor(PreferenceConstants.P_STRING,
"A &text preference:", getFieldEditorParent()));
}
#Override
public void init(IWorkbench workbench) {
setPreferenceStore(Activator.getDefault().getPreferenceStore());
setDescription("A demonstration of a preference page implementation");
}
You can use a ScopedPreferenceStore for the project as the preference store passed to setPreferenceStore. Create it like this:
new ScopedPreferenceStore(new ProjectScope(project), "your plugin id");
where project is the IProject for the project.

I currently have en Eclipse plugin that provides a multi-page editor, one page for a visual editor and one page for a source editor, similar to other editors, i.e:
This is the important part of my code:
public class DockerfileEditor extends FormEditor implements IResourceChangeListener {
....
#Override
protected void addPages() {
try {
SourceEditor sourceEditor = new SourceEditor(); // Extends from EditorPart
addPage(new DesignForm(this, "Design")); //$NON-NLS-1$
addPage(sourceEditor, sourceEditor.getEditorInput());
} catch (PartInitException e) {
e.printStackTrace();
}
}
}
In the addPages() method I'm adding my 2 pages, the first of them extends from FormPage so setting the title is really easy, but the second page extends from EditorPart (this will be my source editor), how can I set the title of this page?
addPage returns you the index of the page that was added so you can use:
int pageIndex = addPage(sourceEditor, sourceEditor.getEditorInput());
setPageText(pageIndex, "Source");
I am new to android. My Preference Screen option is not showing. I am following below tutorial section "Preferences" and "Creating the Settings Activity"(https://wiki.oulu.fi/display/esde/List+views%2C+Intents%2C+Preferences+and+Notifications)
This is my SettingsActivity.java class
public class SettingsActivity extends Activity {
public static class SettingsFragment extends PreferenceFragment {
private SettingsFragment settingsFragment = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Load the preferences from an XML resource
addPreferencesFromResource(R.xml.preferences);
settingsFragment = new SettingsFragment();
// Display the fragment as the main content.
getFragmentManager().beginTransaction()
.replace(android.R.id.content, settingsFragment)
.commit();
}
}
This is the settings for Preference
<?xml version="1.0" encoding="utf-8"?>
<PreferenceCategory android:title="#string/server_settings" >
</PreferenceCategory>
<CheckBoxPreference
android:defaultValue="false"
android:key="#+id/pref_check"
android:summaryOff="#string/pref_off"
android:summaryOn="#string/pref_on" >
</CheckBoxPreference>
<EditTextPreference
android:key="#+id/pref_edit"
android:defaultValue="#string/pref_default"
android:dialogTitle="#string/edit_text_pref">
</EditTextPreference>
In the main activity I have below method for launching SettingActivity class.
// launch the settings activity
public boolean onOptionsItemSelected(MenuItem item) {
startActivity(new Intent(this, SettingsActivity.class));
//return super.onOptionsItemSelected(item);
return true;
}
Also I have added below code under main activity, onCreate method to initialize the default values for the settings, from the preferences setting file
PreferenceManager.setDefaultValues(this, R.xml.preferences, false);
Could you help me on this issue?
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));
When i am going to one page(A) to another page(B) using Ajax link URL show like ...?wicket:interface=:58::::#
On B page i have a link for open model window.when we direct click on link of model window its working fine but when first open link in new Tab by right click and then click on model window link its throwing an error.
I am using setResponsePage( new B(variable)) for come to another page.when i am using setResponsePage(B.class) instead of setResponsePage( new B(variable)) its working fine.
Note : I don't want to use pageparameter with bookmarkable and setResponsePage.
Error is :
org.apache.wicket.WicketRuntimeException: component listForm:group:issueList:1:editStatus not found on page com.B[id = 18], listener interface = [RequestListenerInterface name=IBehaviorListener, method=public abstract void org.apache.wicket.behavior.IBehaviorListener.onRequest()]
org.apache.wicket.protocol.http.request.InvalidUrlException: org.apache.wicket.WicketRuntimeException: component listForm:group:issueList:1:editStatus not found on page com.B[id = 18], listener interface = [RequestListenerInterface name=IBehaviorListener, method=public abstract void org.apache.wicket.behavior.IBehaviorListener.onRequest()]

"editStatus" is a link name on model window.
Code that i am using Class A
class A extends WebPage {
Link<String> escalated = new Link<String>("escalated") {
public void onClick() {
setResponsePage(new B(Variables));
} };
}
class B extends WebPage {
public B(variables..) {
}
final ModalWindow model = new ModalWindow("UpdateModel");
model.setContent(new C(model,variables,model.getContentId()));
item.add(new AjaxLink<Void>(**"editStatus"**) {
public void onClick(AjaxRequestTarget target) {
model.show(target);
}
}.add(new Image("edit_icon", "image/edit.png")));
}
}
class C extends Panel {
public C(.....) {
}
}
I have solved this issue.Error was relating with state of wicket component.
Use StatelessLink instead of Link.
correct code :
class A extends WebPage {
StatelessLink escalated = new StatelessLink("escalated") {
public void onClick() {
setResponsePage(new B(Variables));
} };
}
it would also removed "...?wicket:interface=:58::::#" from url.
when we used Link,AjaxLink it would maintain state.so when we open any link in new tab it would changed state on server side(change ids of component) but on client side it would remain same. so when we click any link on same page there are no information of updated ids and it would have thrown an error.
I have implemented my own editor and added a code completion functionality to it. My content assistant is registered in source viewer configuration like this:
public IContentAssistant getContentAssistant(ISourceViewer sourceViewer) {
if (assistant == null) {
assistant = new ContentAssistant();
assistant.setDocumentPartitioning(getConfiguredDocumentPartitioning(sourceViewer));
assistant.setContentAssistProcessor(getMyAssistProcessor(),
MyPartitionScanner.DESIRED_PARTITION_FOR_MY_ASSISTANCE);
assistant.enableAutoActivation(true);
assistant.setAutoActivationDelay(500);
assistant.setProposalPopupOrientation(IContentAssistant.PROPOSAL_OVERLAY);
assistant.setContextInformationPopupOrientation(IContentAssistant.CONTEXT_INFO_ABOVE);
}
return assistant;
}
When I press Ctrl + SPACE inside the desired partition, the completion popup appears and works as expected.
And here's my question.. How do I implement/register a documentation popup that appears next to completion popup? (For example in java editor)
Well,
I'll answear the question myself ;-)
You have to add this line
assistant.setInformationControlCreator(getInformationControlCreator(sourceViewer));
to the configuration above. Then when creating CompletionProposals, the eighth (last) parameter called additionalProposalInfo of the constructor is the text, which will be shown in the documentation popup.
new CompletionProposal(replacementString,
replacementOffset,
replacementLength,
cursorPosition,
image,
displayString,
contextInformation,
additionalProposalInfo);
More information about can be found here.
Easy, isn't it.. if you know how to do it ;)
For the styled information box (just like in JDT).
The DefaultInformationControl instance need to received a HTMLTextPresenter.
import org.eclipse.jface.internal.text.html.HTMLTextPresenter;
public class MyConfiguration extends SourceViewerConfiguration {
[...]
public IContentAssistant getContentAssistant(ISourceViewer sourceViewer) {
if (assistant == null) {
[...]
assistant.setInformationControlCreator(getInformationControlCreator(sourceViewer));
}
return assistant;
}
#Override
public IInformationControlCreator getInformationControlCreator(ISourceViewer sourceViewer) {
return new IInformationControlCreator() {
public IInformationControl createInformationControl(Shell parent) {
return new DefaultInformationControl(parent,new HTMLTextPresenter(false));
}
};
}
}
Proposals can then use basic HTML tags in the string from method getAdditionalProposalInfo().
public class MyProposal implements ICompletionProposal {
[...]
#Override
public String getAdditionalProposalInfo() {
return "<b>Hello</b> <i>World</i>!";
}
}
