Re: [nebula-dev] Ordering columns programmatically?

Donald,

As for the first, I pretty much got that from the code but somewhere along the line I lost my items in the dropdown. I can back out of it and find where I messed up so I’m not too concerned with that. As for the second, I was thinking more in terms of adding Javadoc right in the code so that when browsing or using the Eclipse Javadoc view there would be more documentation for the developer. There is some but it is lacking in most places. As long as the code isn’t modified and all that is added is Javadoc comments, would one still go through the patch process?

 

Also one interesting observation I noticed from your example but haven’t had time to investigate as of yet: If you select a customization either through the Table Customization dialog or from the dropdown menu on the toolbar, then it appears to allow column moving and sorting on any column. However, if you select either of the custimizations from their icon on the toolbar then trying to sort any column give this message in the console:

Only much longer than what I pasted here and the sorting gets ignored. Column moving however seems unaffected.

 

I am taking vacation after today for the rest of the year but will be back at it when I return. Thanks for your help

Mike:

 

First:

 

The original purpose of table customizations was to allow the user in real-time to organize their table and persist these customizations for selection later.

 

Your use case, which is a good one also, is for the developer to provide a canned set of layouts to allow the user to select.  These can be provided through the same mechanism as the saving/loading of the user customizations.

 

To provide either case, you want to extend XViewerCustomizations and provide it to your XViewer through your XViewerFactory via the getXViewerCustomizations method.

 

See the example MyXViewerCustomizations and MyXViewerFactory classes.

 

MyXViewerCustomizations provides the two "canned" customizations through getSavedCustDatas().  Implementing the rest of the methods provides the other case where the user can create their own and persist to filesystem, database, workspace or wherever the developer wants to persist.

 

Second:

 

I have started some documentation at http://wiki.eclipse.org/Nebula_XViewer_Getting_Started, but it is certainly lacking.  I wouldn't mind you taking a crack at enhancing the information as you learn about XViewer.  It's definitely on my list to get done, but other things always seem to get in the way.  :>)

 

Regarding updates to the code.  The correct method is for interested parties to provide patches through bugzilla.  Time permitting, one of the XViewer committers can review and apply the patches.

 

Hope that helps,

Don

Donald,

Great stuff! I got it working with our project EMF model and created 4 different ToolItems to represent my data groupings. I have two questions on the implementation. First, I fail to see the implementation that handles adding menu items to the dropdown list (your example has “Name Status” and “Name Description”). Second, as a result of the first (I’m assuming here) my CustomizeData objects don’t show up in the Table Customization like yours did (again, the same two that were in the dropdown)? I fail to wee where I lost this? The only thing I removed was the refresh button because I am using EMF data binding instead. I tested that removal on your example and it had no effect on ToolItems in you dropdown nor did it remove them from the Table Customization so I’m confident that didn’t affect anything? There is a lot of code and functionality in XViewer and yes examples certainly explain things. However, you can’t provide examples for everything you can do with it and here is where documentation would be useful. If I could find time to add some Java Doc to the classes at least to get the process started, what would be the process of getting the classes promoted to the repository be? I’ve kind of been following some of the additions and changes that others have contributed that last couple of months. What would be nice is to maybe have omething like separate repository branches so changes could be committed without affecting anything else. Then the changes could be reviewed and accepted or rejected from the repository time permitting? What do you think?

I've added an example of this to the example package withing the xviewer plugin.  Sync up the latest source code to see it. 

You can run MyXViewerTest.java  (in Eclipse, right-click -> Run-As -> Java Application) to see it work.

 

The customization icon allows the user to easily toggle between the table default and their stored options.

Also added MyDefaultCustomizations to answer your question, Mike, on how to build a CustomizeData object to be sent in upon user selecting to change.  The example also has two items at the top to show how they can be used.

 

To also answer your question here:

 

   public static CustomizeData getCompletionCustomization() {
      CustomizeData data = "" CustomizeData();
      data.setName("Name Status");
      data.setGuid(XViewerLib.generateGuidStr());
      data.setNameSpace(MyXViewerFactory.COLUMN_NAMESPACE);

 

      XViewerColumn nameColumn = MyXViewerFactory.Name_Col.copy();
      nameColumn.setSortForward(true);
      nameColumn.setWidth(175);
      nameColumn.setShow(true);
      data.getColumnData().getColumns().add(nameColumn);

 

      XViewerColumn percentCol = MyXViewerFactory.Completed_Col.copy();
      percentCol.setWidth(150);
      percentCol.setShow(true);

 

      data.getColumnData().getColumns().add(percentCol);
      return data;
   }

Hope that helps,

Don

Thanks Donald,

I’ve been looking at the code for CustomizeManager, CustomizeData, XViewerColumn, and XViewerFactory to try and determine the best way to go about creating CustomizeData objects to represent my data groupings. Currently in the example code the columns are created and registered in the factory class. As well, what you see in the table are those columns created and registered from the factory class. Are you saying that I should create XViewerColumns and add then to a CustomizeData object along with any filters and sorters I might want and then just load a customization selected by the user as described below. I’m failing to see the connection between the columns defined in the XViewerFactory and those defined from a CustomizeData object? Do all columns need to be defined from the MyXViewerFactory up front and then added to a CustomizeData object to create the different data views? Could you elaborate a little on this process?

 

TIA,

Mike

Since an XViewer customization includes width, sorting, filtering and etc, you can't just reorder the columns, you have to set a full CustomizationData object.  From XViewer class, you can getCustomizationMgr().loadCustomization(CustomizeData)

 

Your pulldown selection can just select the appropriate CustomizeData and set it.

Subject: [nebula-dev] Ordering columns programmatically?

Maybe someone can help me here? I want to be able to build different pre-defined data groupings. I have a dropdown which allows the user to select the group of data they want to see. In the process of doing this the order of the columns needs to change to match the new data and grouping. This requires me to add/delete some columns as well as reorder some columns. I provide content and label providers to define each data grouping and reset them and the input when the user makes a selection from the Group By dropdown menu. I added a function in my extension of the XViewer Factory that calls clearColumnRegistration and then I re-register the columns in the order I want. Problem is that the columns never reorder. The new content and label providers appear to get set and my data gets re-ordered but the column headers remain in the same position? So the headers don’t match the column data? I now you can hide and reorder columns from the Customize Dialog and by just dragging columns to a different position but I’m interested in doing this programmatically to get the data the user really wants to see and the way they want to see it. I’m I going about this in the right way or am I missing something? Anyone try something like this yet? Any explanation of why I can’t reorder the columns by clearing them from the registration and re-registering then would be helpful.

 

TIA,

Michael
