Re: [platform-swt-dev] Table with multiple Listeners and Editors
|
Hi Andreas,
This kind of questions should be post to the swt newgroup (see
http://www.eclipse.org/newsgroups/index.html).
You should check out the others SWT snippets
(http://dev.eclipse.org/viewcvs/index.cgi/%7Echeckout%7E/platform-swt-home/dev.html#snippets),
specially:
-place arbitrary controls in a table
-edit a cell in a table (in place, fancy)
The snippet you are testing hard code the EDITABLECOLUMN column to 1, I
made a small modification to it to show how you can set the editable
column using the event coordinates. Here is the code:

[platform-swt-dev] Table with multiple Listeners and Editors
Hello all,
i'm just using a simple table to display some data, i would like to make
some fields of the table editable, for example in a Table with 5 columns,
i would like to make the columns 3 and 4 editable.
I found a snipped which does the stuff for one column using a TableEditor
http://www.jlab.net/eclipse/doc/3.0/org/eclipse/swt/custom/TableEditor.html
i can't figure out, how i can do the same for multiple columns, does
anybody know how this works?
I was also thinking about using a drop down list for one column, ie. it
should allow to choose a value from a pre-defined set. This can be
different for each row, for example:
i use a list of parameters which are shown in a table, each parameter
possibly has a different type
the first row contains a boolean parameter, therefore: in cell number 2
you can select from[true,false]
the second row contains a parameter which uses a value set: in cell number
2 you can select from [1,2,3,5,6]
Does anybody know if this is possible with a simple swt table? any hints?
Many thanks
Andy
