| Re: [nebula-dev] Ordering columns programmatically? |

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

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? Mike
From:
nebula-dev-bounces@xxxxxxxxxxx [mailto:nebula-dev-bounces@xxxxxxxxxxx] On Behalf Of Dunne, Donald G 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()
{
XViewerColumn nameColumn =
MyXViewerFactory.Name_Col.copy();
XViewerColumn percentCol =
MyXViewerFactory.Completed_Col.copy();
data.getColumnData().getColumns().add(percentCol); Hope that

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 From:
nebula-dev-bounces@xxxxxxxxxxx [mailto:nebula-dev-bounces@xxxxxxxxxxx] On Behalf Of Dunne, Donald G 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. From:
nebula-dev-bounces@xxxxxxxxxxx [mailto:nebula-dev-bounces@xxxxxxxxxxx] On Behalf Of Stapleton, Mike 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 |
