I am trying to make a window form in Mono develop.
in the form, I need a Combobox Entry with Autocomplete/AutoSuggest feature.
Could any one guide me how to do it?
Check this feature out on an Entry field called EntryCompletion:
Entry entry = new Entry ();
entry.Completion = new EntryCompletion ();
There is an an example here of doing an search auto complete.
Edit:
Here is the Documentation for the feature with the same example

This feature has been realized as of Kepler M4, for a detailed information on the usage see my blog
I want to realize a fully dynamic menu contribution to the menu of a handler located in a view toolbar. In Eclipse 3 it was possible to add "dynamic" as org.eclipse.ui.menus contribution to a Menu!
I already found out about www.vogella.com/blog/2010/10/26/processors-e4-model explaining on how to dynamically contribute to menus by means of processor model extensions but I am talking about a completely dynamic menu implementation which changes on every call of the resp. submenu. As mentioned this was no problem to realize in Eclipse 3.x via the dynamic menu contribution and the set of isDynamic() to true.
I already tried several approaches:
Registering a processor hooking to a menu => no dynamic add possible (new elements are simply not shown, also discussed in Eclipse Forum - Cannot replace menu items at runtime)
Listening to the UIEventTopic for the event of creating the menu, getting the widget for Modification => modifications to the swt.Menu gathered are simply ignored (every listener, element etc.) (for info RCP Event Model
Open, untried solutions
Inserting a ToolControl to try an SWT approach -> quite complicated but may work
I've been banging my head for some time now, but can't seem to understand the correct implementation of this problem within E4.
-- This question was also asked in Eclipse Forum - Dynamic menu contributions
----- UPDATE
I tried a different approach up to now:
I added a HandledToolItem to the Menu (please see the following image)
and with the following code I am trying to interfere with the menus way to build, where the code is called by the resp. command handleer as referenced in the image.
#CanExecute
public boolean canExecute(#Optional MApplication application) {
System.out.println("CanExecute Counter="+counter);
// --- 1 ---
// Find the required MMenu Entry in the Application Model
if(application == null) return true;
EModelService modelService = (EModelService) application.getContext().get(EModelService.class.getName());
MPart part = (MPart) modelService.find("at.medevit.emr.contacts.ui.contactselector", application);
List<MToolBarElement> lmte = part.getToolbar().getChildren();
HandledToolItemImpl htil = null;
for (MToolBarElement mToolBarElement : lmte) {
if(mToolBarElement.getElementId().equals("at.medevit.emr.contacts.ui.contactselector.toolbar.handledtoolitem.filter")) htil = (HandledToolItemImpl) mToolBarElement;
}
if(htil != null) {
MMenu elemMenu = htil.getMenu();
// --- 2 ---
// Found it hopefully, let's start the real work, simply add a new item
MDirectMenuItem mdi = MMenuFactory.INSTANCE.createDirectMenuItem();
mdi.setLabel("Counter "+counter);
counter++;
// --- 3 ---
elemMenu.getChildren().add(mdi); // ConcurrentModificationException
}
As one can see, this code is queried once the menu is created, to determine whether the command is executable or not. All the code from 1 - 2 is to find the correct MMenu element to work on. The code from 2 - 3 creates a MenuItem and increments a counter in the field.
BUT at 3 I face a java.util.ConcurrentModificationException the first time the menu is opened! I assume that at this very point the menu is iterating over elemMenu.getChildren() and I am not allowed to enable!
So whats all the fuzz about the entire e4 model being changeable all the time ;) (just kiddin' I know this is a baaaad hack!!!)
Thing is: I really think that the possibility to add fully dynamic menu parts is one of the best usability tools, and if it is not possible to realize it in E4 as it was in E3 this is a very serious degradation of possibilities!!!
-- UPDATE
An Eclipse Bug has been filed for this https://bugs.eclipse.org/bugs/show_bug.cgi?id=389063
Proper dynamic model updates should be handled in the bug you've opened. As a workaround in Eclipse4 in Juno, a MRenderedMenuItem can be created in Eclipse4 to provide the equivalent functionality to the dynamic element (although if you are using 4.2, you would just use org.eclipse.ui.menus).
ex:
ContextFunction generator = new ContextFunction() {
#Override
public Object compute(IEclipseContext context) {
return new MyCompoundContributionItem(context);
}
};
MRenderedMenuItem menuItem = MenuFactoryImpl.eINSTANCE.createRenderedMenuItem();
menuItem.setElementId(id);
menuItem.setContributionItem(generator);
container.getChildren().add(menuItem);
This effectively provides a CompoundContributionItem directly to the Eclipse4 menu renderer.
I am new to NatTable and was looking to print the NatTable.
I know about paperClips for SWT tables but couldn't find anything similar for Nattable.
has anyone tried printing or even saving the Nattable data as imagedata?
You can press CTRL+P while the NatTable has focus. This should give you a print dialog.
In code it will create a new PrintAction. Check out:
org.eclipse.nebula.widgets.nattable.print.action.PrintAction to see how that works.
That's true in case you are using a GridLayer with DefaultGridLayerConfiguration. There the DefaultPrintBindings are aggregated which add the binding for CTRL+P.
Also the PrintCommandHandler is registered against the GridLayer.
So if you are using a GridLayer, the above statement is perfectly correct, otherwise you need to ensure to register the PrintCommandHandler and the corresponding binding to your layer composition.
I want to add a new custom component in the Web page Editor Palete named "myHTMLComponent".
So, as soon as user opens any html page with WPE, myHTMLComponentM should be present there.
How can I do the needful, moreover this component will as well need to generate the code changes accordingly. How to achieve the desired result.
Is there any input I can get for this.
I already created standardmetadata tag, but what next!
Finally, I found the solution of the problem.
For adding new categories in the palette, we need to use pagedesignerextension in plugin.xml as following -
<extension
point="org.eclipse.jst.pagedesigner.pageDesignerExtension">
<paletteFactory
class="com.comp.myeditor.palette.CustomEditorPaletteFactory">
</paletteFactory>
</extension>
Where CustomEditorPaletteFactory will be extending AbstractPaletteFactory. Here in createPaletteRoot(), we can add our category.
public PaletteRoot createPaletteRoot(IEditorInput editorInput){
PaletteRoot paletteRoot = new PaletteRoot();
paletteRoot.add(createStandardComponents());
return paletteRoot;
//return null;
}
private static PaletteContainer createStandardComponents() {
PaletteDrawer componentsDrawer = new PaletteDrawer("CustomHTMLComponent");
TagToolPaletteEntry paletteEntry = new TagToolPaletteEntry(
new FormPaletteComponent(".....);
componentsDrawer.add(paletteEntry);
return componentsDrawer;
}
This will create the component category in the palette and we can add as many components as needed using the componentsdrawer.
For adding a new category in the existing one -
Add this in the constructor -
super();
this._paletteContext = PaletteItemManager.createPaletteContext(file);
this._manager = PaletteItemManager.getInstance(_paletteContext);
Then use Palette Grouping like this -
PaletteGroup controls = new PaletteGroup("CUST HTML");
super.add(controls);
ToolEntry tool = new SelectionToolEntry("CUST Cursor",
"Cursor DESCRIPTION");
controls.add(tool);
setDefaultEntry(tool);
//Custom Marquee
controls.add(new MarqueeToolEntry("Marquee", "Marquee Desc"));
controls.add(new PaletteSeparator());
//This class maintins or load all categories features
controls.add(new CustomComponentToolEntry("Custom Component", "Custom Component Descrition",
This really is a good start but I can't find any tutorial or book that get deeper in this matter. For instance, I don't want to replace the default palette but this code does with "new PaletteRoot()" and I lost my HTML tags. Also I want that my new custom components behave as HTML Tags using Drag and Drop, but I don't know how?????????
More Info:
I discovered this code, that was very helpful, whereas file come from ((FileEditorInput)editorInput).getFile()
PaletteRoot paletteRoot = DesignerPaletteRootFactory.createPaletteRoot(file);
This is very interesting topic and I think we are pioneer documenting this feature of eclipse. Here other good point, I want to personalize the tag... e.g. something similiar what I want to achieve is add a tag like "MY TRUEFALSE TAG" and then when is selected and place it in the HTML Designer, I want to become something like <select><option>YES</option><option>NO</option></select> and I guess that I can achieve it by doing something with the tagTransformOperation extension... if you know how to implement it, please let me know. also there is others extensions(tagConverterFactory, elValueResolver). I am guessing here! please I would like your help.
<extension point="org.eclipse.jst.pagedesigner.pageDesignerExtension">
<paletteFactory ...>
<tagTransformOperation id="plugin.tagTransformOperation1XXXXXX">...
SOLUTION?? (Chinese) -solved with tagConverterFactory

I want to create a word 2007 document without using object model. So I would prefer to create it using open xml format. So far I have been able to create the document. Now I want to add a content control in it and map it to xml. Can anybody guide me regarding the same???
Anoop,
You said that you are able to creat the document using OpenXmlSdk. With that assumption, you can use the following code to create the content control to add to the Wordprocessing.Body element of your Document.
//praragraph to be added to the rich text content control
Run run = new Run(new Text("Insert any text Here") { Space = StaticTextConstants.Preserve });
Paragraph paragraph = new Paragraph(run);
SdtProperties sdtPr = new SdtProperties(
new Alias { Val = "MyContentCotrol" },
new Tag { Val = "_myContentControl" });
SdtContentBlock sdtCBlock = new SdtContentBlock(paragraph);
SdtBlock sdtBlock = new SdtBlock(sdtPr, sdtCBlock);
//add this content control to the body of the word document
WordprocessingDocument wDoc = WordprocessingDocument.Open(path, true); //path is where your word 2007 file is
Body mBody = wDoc.MainDocumentPart.Document.Body;
mBody.AppendChild(sdtBlock);
wDoc.MainDocumentPart.Document.Save();
wDoc.Dispose();
I hope this answers a part of your question. I did not understand what you ment by "Map it to XML". Did you mean to say you want to create CustomXmlBlock and add the ContentControl to it?
Have a look for the Word Content Control Toolkit on www.codeplex.com.
Here is a very brief explanation on how to do what you are attempting.
You need to have access to the developer tab on the Word ribbon. To get this working click on the Office (Round thingy) in the top left hand corner and Select Word Options at the bottom of the menu. On the first options page there is a checkbox to show the developer toolbar.
Use the developer toolbar to add the Content controls you want on the page. Click the properties button in the Content controls section of the developer bar and set the name and tag properties (I stick to naming the name and tag fields with the same name).
Save and close the word document.
Open the Content control toolkit and then open your document with the toolkit. Use the left hand pain to create some custom xml to link to your controls.
Now use the bind view to drag and drop the mappings between your custom xml and the custom controls that are displayed in the right panel of the toolkit.
You can use the openxml sdk 1.0 or 2.0 (still in ctp) to open your word document in code and access the custom xml file that is contained as part of the word document.
If you want to have a look at how your word document looks as xml. Make a copy of your word document and then rename it to say "a.zip". Double click on the zip file and then navigate the folder structure. The main content of the word document is held under the word folder in a file called "document.xml". The custom xml part of the document is held under the customXml folder and is generally found in the file named "item1.xml".
I hope this brief explanation get you up and running.
I'm looking for a Combo(Viewer) in SWT/JFace which supports autocomplete / type-ahead, i.e. the user can enter a couple of characters and the drop down list should show all matching elements.
You can also check out the org.eclipse.jface.fieldassist.AutoCompleteField class. It's not a combo, just a text field, but it adds auto complete functionality as if it were a combo very easily. You can do something as simple as this:
Text textField = new Text(parentComposite, SWT.BORDER);
new AutoCompleteField(textField, new TextContentAdapter(), new String[]
{"autocomplete option 1", "autocomplete option 2"});
I don't think there is anything like this built into either Combo or ComboViewer.
As thehiatus suggests org.eclipse.jface.fieldassist.AutoCompleteField is probably the best place to look for this, however, there is support for Combos:
new AutoCompleteField(combo, new ComboContentAdapter(), new String[]
{"item0", "item1"});
You may be interested in Eclipse's "Content Assist" feature. You can see it in action when using the Eclipse IDE's Java editor. As you edit source code, you will sometimes see a drop-down menu with phrases that complete what you were typing. (Note that you can press Ctrl+Space to force the drop-down menu to be displayed.)
You can implement this in your own SWT/JFace application as well. The "Java Developer's Guide to Eclipse" has an sample application that implements Content Assist. The sample application is a SQL editor, and it is described in Chapter 26, "Building a Custom Text Editor with JFace Text." There's actually an online overview of the chapter here. The sample SQL editor project, com.ibm.jdg2e.editor.jfacetext.sql, can be found here.
On the other hand, if you want to create your own Combo widget and auto-populate it based on input that is being entered, then this might not be very applicable. I'm thinking the org.eclipse.jface.viewers.ComboViewer might be helpful (though I'm not positive).
Check out: http://sourceforge.net/projects/swtaddons/
I use it in my project (with a little tweak).
It's really dead easy to set this up.
As thanks to paz117's comment, thought I'd share the code to make this work:
String[] proposals = new String[controller.model().size()];
for (int i = 0; i < controller.model().size(); i++)
proposals[i] = controller.model().get(i).getAppropriateName();
comboViewer = new ComboViewer(parent, SWT.NONE);
comboViewer.setContentProvider(new ArrayContentProvider());
comboViewer.setLabelProvider(new AppropriateLabelProvider());
comboViewer.setInput(_controller.model());
// additionally, configure the comboViewer arbitrary
new AutoCompleteField(comboViewer.getCombo(), new ComboContentAdapter(), proposals);
The only minor nuisance is that you have to separately populate the model of ComboViewer and AutoCompleteField separately, but that can be at least automated via a static utility method or something similar.
As reference for future visitors, the AutocompleteComboInput (SWT Add-on), can also be a way to achieve this.
Code snippet for screenshot (refer to documentation link above for the code template):
import net.sf.swtaddons.autocomplete.combo.AutocompleteComboInput;
...
subjectCodeCombo = new Combo(tab3Composite, SWT.DROP_DOWN);
// other code modifying Combo appearance here...
// returns a String[] of items retrieved from database
String[] subjectCodeArray = dbQuery.subjectsToArray();
subjectCodeCombo.setItems(subjectCodeArray);
subjectCodeCombo.setText("- SELECT -");
new AutocompleteComboInput(subjectCodeCombo);
The add-on requires all JARs below to be added to the Library: (more info)
eclipse-equinox-common-3.5.0.jar
