Donald (and those who
are interested),
From my testing I can
get the tree behavior to change the root node and the underlying node
relationship, in other words select predefined tree views for the data available
with out changing the ContentProvider and LabelProvider, if I can let the my
content and label providers know what the selection is from the dropdown menu.
Of course the content and label providers have to know about the user’s
selection prior to myLabelProvider.getColumnText and
myContentProvider.getChildren being called so they will execute the correct
logic based on the menu selection. There looks like there are some places I can
add a listener however, this will do me no good if it can’t update the providers
before they execute. So far this looks like the must logical way to have
multiple tree views. Am I attacking this problem the right way or am I missing
something in the XViewer architect? I know this is not your main concern and you
have plenty of other responsibilities, but any feedback you could provide would
be greatly appreciated.
Thank
You,
Michael

Donald (or anyone who
would like to chime in),
I got switching between
predefined tables working nicely using your example. However, I have a
requirement to switch between tables and tree views in the same application. I
can do one or the other from different applications but when I try to do both in
the same application I have conflicts with the content and label providers that
represent the 2 different structures as well as the way I structure the input to
get it to layout properly. Also switching between different tree views is clumsy
because it requires you to restructure your tree. I would think this is
something others would find useful but can’t find any examples or information on
it. Is there a mechanism built into XViewer that that supports these types of
different layouts dynamically? So far I’m back to resetting the content and
label providers to as well as restructuring the input. Any guidance would be
greatly appreciated.
Thanks to anyone who
has time and knowledge to rrespond.
Michael

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
