extension point for custom columns [message #1004015]

Deriving a custom FormField is well documented. It's found via the plugin configuration as described in the tutorial:

      <formField
            scope="global"
            active="true"
            modelClass="org.eclipse.scout.rt.client.ui.form.fields.decimalfield.IDecimalField"
            name="decimalfield">
         <uiClass
               class="ch.sbb.cis.scout.rt.ui.swt.form.fields.decimalfield.CisSwtDecimalField">
         </uiClass>
      </formField>

But for a custom table or column this configuration via the Interface does not work

      <formField
            scope="global"
            active="true"
            modelClass="org.eclipse.scout.rt.ui.basic.table.ICisTable"
            name="table">
         <uiClass
               class="ch.sbb.cis.scout.rt.ui.swt.basic.table.ICisSwtScoutTable">
         </uiClass>
      </formField>

Which tag (if possible) is necessary in the plugin configuration?
In my opinion, is there a missing extension point for org.eclipse.scout.rt.ui.basic or org.eclipse.scout.rt.ui.basic.table

You cannot add a custom UI for org.eclipse.scout.rt.client.ui.basic.table.ITable because it is not a form field (i.e. extends org.eclipse.scout.rt.client.ui.form.fields.IFormField). What you can do, is to provide a custom UI representation for org.eclipse.scout.rt.client.ui.form.fields.tablefield.ITableField. ITable is "just" a model for the table, the field itself is subclassed from ITableField (with an ITable as an inner class).

If you look for example at SwingScoutTableField (the mapping class from the Scout model to the Swing widgets) you can see how the ITable is mapped to a SwingScoutTable in setTableFromScout(). You could provide your own CustomSwingScoutTableField class that creates a custom CustomSwingScoutTable.

But beware, because a table is a rather complex widget, the UI implementation is not that simple, too.

Just for my curiosity, can you provide some inputs on why you need a specific column?

I never had a such use case...

If your use case is "add a MyBean Column" (where MyBean is every Object):

If I remember it correctly, you can add a AbstractColumn<MyBean> in your table.

You probably need to override some of the Operation functions. At least execDecorateCell(..)

If you want to reuse the column you can create an abstract class for it (AbstractMyBeanColumn).

Let me know if you want to know more about this approach.
