Row-wise table editing [message #64712] Fri, 19 June 2009 08:15 Go to next message

Hi,

Is there a support to have different editors on different rows of Nebula
grid? Currently, we can have editors (text, combo etc.) on columns and this
would mean it will display the same editor for that column in all the
rows...My requirement is something kind of a Transposed table. Is it
possible with Nebula Grid?

Thanks

Hi,

Yes this is supported using JFace 3.3 API named EditingSupport where you
are asked every time for an editor before displaying it.

You can simply use the code from
http://wiki.eclipse.org/JFaceSnippets#Snippet034CellEditorPe rRowNewAPI
This is a general rule everything available from JFace upstream is
available in the Nebula-Grid-Viewer (with small exception when it comes
to Grid-TreeViewer) else it is a bug and needs fixing.

Hi Tom,

Thanks for the reply. Yes i did went through the idea you provided in this
article. I can see that you are using Model which is represented in Rows,
although this is the obvious approach of TableViewer/Nebul Grid, my
requirement extends further to the fact that I need Model represented by
Columns rather than rows. Is that possible using the inbuild JFace APIs? or
i will have to do something manually to manage the Model input/output ?

Consider a normal Nebula Grid editor but Rows will take place of Columns and
vice-versa.

Thanks
Mustufa

Hi,

Sorry I don't get the problem. Whenever the viewer wants to show an
editor he asks the EditingSupport for one.

Based on the information provided to you (you know the column and you
get the domain-object representing the row) you can switch your editor
for every single cell.

Are you asking for a viewer where the Columns are the dynamic part
instead of the rows? Then this is not possible but you should be able to
handle this at the model part by transforming your column domain model
into a row model and feeding it into the viewer. But you original
question was about something completely different so I'm not sure I
understood your problem.

Hi Tom,

I think you got my question that I want a viewer where Columns are the
dynamic part. Sorry for the confusion. The previous question was related to
this one as i want dynamic columns plus different editor on each row.

Your suggestion about transforming Column model to Row model could be
explored (it will too complicated though). I was just looking if there is
some inbuilt facility already provided by Nebula Grid.

Anyways, Thanks a lot for the answers.

Hi,

There no such support for this but IMHO transforming a Row-Model into
Column-Model isn't a problem. Using reflection this is done quite easily
in a generic manner.

I just gave it a try and came up with the snippet attached to this mail
and available from our snippets collection.

Hi,

Yes this is supported using JFace 3.3 API named EditingSupport where you
are asked every time for an editor before displaying it.

You can simply use the code from
http://wiki.eclipse.org/JFaceSnippets#Snippet034CellEditorPe rRowNewAPI
This is a general rule everything available from JFace upstream is
available in the Nebula-Grid-Viewer (with small exception when it comes
to Grid-TreeViewer) else it is a bug and needs fixing.

Hi Tom,

Thanks for the reply. Yes i did went through the idea you provided in this
article. I can see that you are using Model which is represented in Rows,
although this is the obvious approach of TableViewer/Nebul Grid, my
requirement extends further to the fact that I need Model represented by
Columns rather than rows. Is that possible using the inbuild JFace APIs? or
i will have to do something manually to manage the Model input/output ?

Consider a normal Nebula Grid editor but Rows will take place of Columns and
vice-versa.

Thanks
Mustufa

Hi,

Sorry I don't get the problem. Whenever the viewer wants to show an
editor he asks the EditingSupport for one.

Based on the information provided to you (you know the column and you
get the domain-object representing the row) you can switch your editor
for every single cell.

Are you asking for a viewer where the Columns are the dynamic part
instead of the rows? Then this is not possible but you should be able to
handle this at the model part by transforming your column domain model
into a row model and feeding it into the viewer. But you original
question was about something completely different so I'm not sure I
understood your problem.

Hi Tom,

I think you got my question that I want a viewer where Columns are the
dynamic part. Sorry for the confusion. The previous question was related to
this one as i want dynamic columns plus different editor on each row.

Your suggestion about transforming Column model to Row model could be
explored (it will too complicated though). I was just looking if there is
some inbuilt facility already provided by Nebula Grid.

Anyways, Thanks a lot for the answers.

Hi,

There no such support for this but IMHO transforming a Row-Model into
Column-Model isn't a problem. Using reflection this is done quite easily
in a generic manner.

I just gave it a try and came up with the snippet attached to this mail
and available from our snippets collection.
