DataGrid auto-set column width

[misko237]

I have a problem with DataGrid in gwt 2.4. I made table with
CellTable, and everything worked fine. But I needed fixed header, and
then just replaced CellTable with DataGrid. I had problem with .css
file, but than has been resolved.

Now, the problem is that every column have fixed width. I need each
column width to be set as the widest cell in entire column.

Can someone help to make old looking, but with fixed header.

Thanks!

I have the same problem.

For me there are two solutions:
1) calculate the maximum field width at runtime by inspecting the row
data. Then set the field header size.
2) leave as stock and listen for a mouse click or similar on each
field header and then resize it.

I have tried the first solution, and I couldn't manage to read real
cell width at runtime. The second one is not suitable for me.

I have tried with first solution, but I couldn't manage to read real
cell element width. Did you succeed? Second solution is not an option

for me.

Okay - for the first solution I did as follows:
1) for each row of data
1.1) for each field
1.1.1) count the number of characters
1.1.2) keep a running maximum
2) finally you have an array of maximum sizes where each index
corresponds to a column, e.g. List<Integer> maxes;
3) for each cell column
3.1) set the width to the maximum using the unit EM.
Note: this is likely to make the column a little bigger than required.
You can also try the Unit EX

Yeah, it might be a solution (not so nice and clean, but solution)...

But, look at this
http://gwt.google.com/samples/Showcase/Showcase.html#!CwDataGrid

They've made GridTable without setting column width (there is no width
attribute on any element).

Hi,
Had a quick look at this:1) they set dataGrid.setWidth("100%") - but
this just scales it to the width of the screen. 2) they do set fixed
column widths - have a look at initTableColumns()
They are some useful calls available. Have a look at the
JavaDoc:http://google-web-toolkit.googlecode.com/svn/javadoc/latest/
com/google/gwt/user/cellview/client/
DataGrid.html#setTableWidth(double,
com.google.gwt.dom.client.Style.Unit)

OK it is 100% width, but on the link I sent to you, they have columns
with different width, and that width is not set. Am I wrong?

When I make DataGrid, I got equal column width. My table with divide
on equal parts.
eg. table width = 100px, and I have 5 columns -> every column will
have 20px width
