As seen on the right, I want to create an expandable row. I am confused how to use TableCellBuilder and/or buildContactRow.
Could someone give me any pointers or point me to a tutorial
I am thinking of using a disclosure panel.
You can use Disclosure panel(perfomance is good).
In my project i have tried TableCellBuilder with cell table but not works what i expected.
Using Disclosure panel you can enable animation also. I have created more that 300 Disclosure panel at a single hit dynamically data from mysql db. but it works fine. so perfomance and efficient is faster in UI.

I have a question. I am trying to create an expandable FAQ menu without using a tableviewcontroller. The reason I don't want to use a tableview is because I don't want expandable cells, rather, I want a buttonclick to reveal a label while also sliding down any other buttons on this page.
I'm using Swift in Xcode 7.3
If anyone has any suggestions/knows of a tutorial/a forum post, it would be greatly appreciated.
Thank You.
Sure,nyou could use buttons, and either change constraints on label heights or dynamically add labels. That's a lot of effort and code.
Or, you could use a table view and one of the myriad guides. Remember that table views don't have to be selectable on ever row, and they don't have to display row separator lines (UI).
Indeed you could disable selection on all rows and add buttons to some rows, though I'd personally say that's overkill and why require the user to be 100% accurate with the tap on a button which in your sample image doesn't even look like a button.
My question is: I've an Eclipse RCP table in my view. The table has gridlines Visible and everything is fine. But I want all the cells of first row of the table to be merged as a single row in run-time GUI. How can I achieve this functionality ? Please, I don't expect something like adding a text over the first row obstructing it. If any API level functionality or any clues to do this are welcome.
The swt table is a native widget and does not allow you any span, neither in columns nor in rows. Even OwnerDraw (custom cell rendering) does not support this. The only way I see that could allow you to achieve this kind of hack is the swt table editor which allows you to place controls above cells:
http://www.eclipse.org/swt/snippets/#tableeditor
The table editor tracks the position of single cells and positions controls above them. It hides controls when a cell is not in edit mode, show's them when the cell is in edit mode. You'd have to deactivate this default behavior and make sure the controls are always shown - this should be fairly easy.
The more challenging part would be that you'd have to find out how to place the controls above 2 or more (and not a single) cells.
The only swt control I know to support span is the nebula grid. Grid is a custom control (no native widget) and therefore offers far more possibilites.

u can use GC api to do the needs in table. u can span between two columns.

I have a cellTable with 5-6 columns. I want to put a plus icon in each row on clicking of which will display the details maybe in a disclosure panel. I have been looking around for a while now and I cannot find any information on how to achieve this. Could someone point me in the right direction?
i suspect i probably have to add a cellTree to the column? how do i go about this?
Thank you for your response in advance.
There is work in progress to allow expandable rows in CellTable among other features (maybe GWT 2.3). You can see more details here:
http://groups.google.com/group/google-web-toolkit-contributors/browse_thread/thread/b4a8a6e3c98ac061#
If that is not enough or you can not wait untill it is released I can think of two ways to achieve it:
As you said, using a CellTree.
Creating a custom cell that stores
state (open/close). Depending on the
state the cell will render
differently. In same way it is
similar to how EditTextCell works, in
"edit" state it renders an input
field while in "normal" state it renders
simple text.
I'm trying to do that too ... I managed to mimic that functionality toying with the html and a custom cell class that allows clickable pictures.
It is working for normal content such as text but if you'd like to get an asynchronous data to show in the expended line, I don't know how to do it ... (I'm trying to do exactly that).
Also, it doesn't look good because the columns don't align well ...
So what I've done is:
- create a custom cell class to display a picture (right pointing triangle, looking like the triangle in the disclosure panel)
In the click event get the HTML code of the selected row and copy it. Replace the content of the row (all cells) in the table with only one cell with its colspan set to number of columns. In the cell, add a table with first line the copied row and second line the content to display as expanded.
Get the image to sink an event for closing. In event, reset the original row that we copied.
I hope it helps.
Hie
the demo shows you can click on any column and update the value.
can someone share the code how it has been implemented?
Hi You can use GwtExt or SmartGWT Editable grid and it also gives components for implementing Paging in it.
link to editable grid in GwtExt is here
You can also find paging that is also local and remote both
I have a table view in which i am reordering my cells
Now the issue is that the client doesn't like the icon of the reorder (i.e. 3 horizontal lines)
Is there any way you can help out.
First of all I want to know Is it possible at all?
You cannot change the standard icon. But you should be able to use a custom button and start/end editing mode programmatically (haven't tested this).
If it isn't a very custom UI at all, tell him that messing with standard icons/behavior is the best way to make users frustrated.
