TableViewer change column amount depending on Input [message #664335]

Hi, I need to change the column amount of my table with the given Input.

I want to display the tabledata depending on the selected table. So the amoutn of columns need to be changed, and also I need to display the column in the header. But I don't really know how to.

Thanks in advance.

Ok, solved this with an extra method which is called at cration of the Controls and everytime my Input is changed.

But this leads me to another question. All my values are written in the first column. How do I get the TableViewer to write the ResultSetData in the correct column.
In the ContentProvider i create an array which holds all values of the result set like this:

Column 1 | Column 2  | Column 3
--------------------------------
Value1.1 | Value 2.1 | Value 3.1
Value1.2 | Value 2.2 | Value 3.2
...

Then my array looks like this:
Value1.1, Value 2.1, Value 3.1, Value 1.2, Value 2.2, Value 3.2...

Is this correct or do I have to create an array for every column?

Edit: Ok, I see the problem is that the columIndex is alway 0 in the method getText from the TableLabelProvider....

I'm not quite sure about the solution. It seems that after selecting another table the columns are beeing added.

It there no way to get a proper TableViewer for a SQL ResultSet where the amounts of columns could differ?

hi,

i had the same problem in a project without using jface and came along that the underlying SWT Table cannot handle different column sizes. At least it works if and only if you get more columns cause adding coumns is allowed and changing the header caption always works.

I used it with SWT.VIRTUAL and disposes all TableHeaders in the SWT.SetData event and recreate the new needed amount of headers. Maybe you have to rewrite much of the code in AbstractStructuredViewer to get this working with JFace but at least this solution works for me without JFace Smile

Good luck
Johan
