Could you give me some ideas on how I can achieve this.
I have SWT Tree with me, which is managed by means of Tree Viewer.
I want every item in the tree to be editable (I mean, if you put mouse on it and start editing its string value , it should change). But the Root item should not change.
User should not be able to modify the top item's name.
As of now Editing Support is provided for all the items in the tree including the top item.
But top item shouldn't be editable.
Kindly give me some idea about it.
Regards,
Venkata Vineel.
If you use JFace you should set a org.eclipse.jface.viewers.EditingSupport implemetation on your org.eclipse.jface.viewers.TreeViewerColumn. The editing-support class has a method org.eclipse.jface.viewers.EditingSupport.canEdit(Object) you have to implement and that should return false for your top-items. For some examples how to use TreeViewers, EditingSupport and all the other stuff regarding JFace see also the JFace Snippets page.

I have a question regarding the linkage of the selection made on the nattable in a custom editor view and the sirius property view. Any ideas, how should i go for it, it will be really kind of you if you can highlight the steps in an easy to understand manner, because i have researched a lot on it and nothing is concrete enough to get me started to solve this task.
I am attaching two screenshots describing, what is the nature of the issue i am facing and what i want to implement.
Screenshots>
1. https://imgur.com/bVqfGc4
In the first screenshot, when i click on the element in the model explorer , its properties show up in the sirius properties view, and they should as that is how sirius property view works
2. https://imgur.com/DKsFQBi
In the second screenshot, when i click on any element on the nattable in a custom editor view containing my nattable, the sirius property view does not respond to the selection made on the nattable in that custom editor view.
I want to implement a solution where when i click on any element in the nattable, its properties hsow up in the sirius property view.
Your help and guidance in this regard will be highly appreciated. Thanks in advance.

You need to implement and register an ISelectionProvider. NatTable provides currently only row based providers like the RowSelectionProvider or the E4SelectionListener.
The corresponding examples can be found here:

Is there a way to add a custom column menu tab with my own favourite icon which on click would render my custom react component?
something like
myColDef.menuTabs: ['generalMenuTab', 'filterMenuTab', 'myCustomMenuTab']
FYI I'm using v12.0.2
What you're after can't be done I'm afraid. The grid supports React components in all sorts of ways (renderers, editors, filters etc), but not via the column menu.
I've updated the docs page to remove the gibberish issue - it'll be fixed properly in the next release, thanks for highlighting this.
This would be helpful to have. In particular for us, we'd like to filter based off row properties, and not row values. Creating our own tab to filter by cell colors that we have assigned with our own set of labels would be useful.
I agree that it would be a nice feature to have. Apparently, there's no quick out-of-the-box solution to do it. The only workaround I see is to implement your own custom Header component which would display any buttons your want.
There you can put a button to open your own custom menu, which you can implement as any regular UI component. It also means you'll need to manually implement all standard menu options that Ag-Grid provides out of the box if you need them.
I have a panorama app that has two panorama items so far, "recent" and "popular." These get populated with data using binding from a viewmodel. I would like to add a third ("search") panorama item that initially shows just a text box and a button.
When the user inputs text and clicks on the button, I want the text box and button to be replaced with the ListBox control that shows the search results.
I cannot find any examples on how to do this using the MVVM pattern. I am not using a MVVM framework and would like not to since I am just learning all this.
If you can explain or better, point me to examples that will allow me to do this, I would very much appreciate the help. If I left out any required info in my request, please let me know.
Sincerely,
Kamal
Typically for something like this you would have a property in your ViewModel that would tell the view what to show. You have lots of different options for how you could do this.
One option would be to have a Results property that your list box is bound to. Put the textbox and button in a Grid and bind the Visibility property of the grid to a property that is Visible is there are no results and not visible if there are.
Lots of different ways to do this.
Examples here and here.
You could probably bind a list of a custom class to the panorama ite .
The custom class contains a title and/or description and a page class.
You can maintain your views in your main viewmodel.
Another solution would be adding the items in xaml and using the same viewmodel for the whole panorama item control. With a property you can control the visibility of each item.
Like Bryant said: there are so many solutions. It depends on your application and requirements... :)
I developed a Sitecore control I'd like to put into a layout on one page.
In this case it's a registration page, and my control is defined as a sublayout.
What I did is went into the Page Editor interface, and plonked the control into one of the placeholders.
What I want to do now is to create a package only containing the information that this control is on this particular page, without affecting e.g. the content or subitems of this node.
Can you please advise on the best way to create such packag, what exactly to select in the Package Designer?
Thanks
I don't believe the Package Designer gives you granular control to include just specific fields of an item. You need to add the item as whole.
You should configure layouts and renderings in the presentation details of an item OR even better in the __Standard Values of the template.
You can call the presentation details dialog through the content editor. Just select an item in the content tree, click on the Presentation tab in the top ribbon and select Details. You can configure all layouts/renderings for the selected item here.
But ff you want to prevent content changes you really SHOULD configure the presentation in the __Standard Values of the template. This is also the way, which is recommended by Sitecore. If you do this, the layouts are all you have to put into a package.
i am using gwt to build my web site.
i would like to create a dropdown/listbox that contains no just text but also images, meaning that in the drop down there will be a what ever widget that ill create.
please advise

You won't be able to do this with a ListBox, because it just creates an HTML < select> element.
You can use a MenuBar that has one menu with MenuItems in it to simulate a dropdown with complex widgets inside it. You will also be able to style the dropdown rather than rely on browser-styled form elements.
Take a look at the Combobox or Suggestion box in Advanced GWT Components.
Another widget is the DropDownListBox in the GWT incubator. I have not used it, but the stated intent is to provide a rich, stylable ListBox. You can pass raw HTML to the addItem() method.
DropDownListBox
it is possible to use Tree inside ScrollPanel, without using nested items
Tree allows TreeItem to be a Widget
