Hello,

I am trying to get text wrapping in the row header region and in cells that are being edited. I thought the following code would do it, but that is not the case. What am I missing?

    natTable.getConfigRegistry().registerConfigAttribute(CellConfigAttributes.CELL_PAINTER, 
        new TextPainter(true, true, 2, true), DisplayMode.NORMAL, GridRegion.BODY);
    natTable.getConfigRegistry().registerConfigAttribute(CellConfigAttributes.CELL_PAINTER, 
        new TextPainter(true, true, 2, true), DisplayMode.EDIT, GridRegion.BODY);
    natTable.getConfigRegistry().registerConfigAttribute(CellConfigAttributes.CELL_PAINTER, 
        new TextPainter(true, true, 2, true), DisplayMode.NORMAL, GridRegion.ROW_HEADER);
    
    natTable.configure();

The way you are applying the configurations is incorrect in terms of the "life-cycle". NatTable#configure() is checking all registered configurations in all layers and applies them. This leads to an overriding of your configurations, as you directly write to the ConfigRegistry before.

Considering the configuration mechanism it is wrong what you are doing, because you don't know if there is a configuration in an IConfiguration registered somewhere, that would override your setting.

If you execute that code after NatTable#configure() it should work. Although I would say it is still a bad practice to do this as a general configuration. Directly writing to the ConfigRegistry afterwards is typically only done to dynamically change the configuration at runtime, not at initialization time.

Your configuration to get a multi-line text editor does not make any sense. You try to register a TextPainter for the edit mode. But in edit mode the painter is not even shown. The editor will take over. To get a multi-line TextEditor, you need to configure the editor. We have the MultiLineTextCellEditor to support editing with multiple lines.

Thanks for the response. When trying out the MultiLineTextCellEditor, I got some strange results. It says it should disable commit on enter, however when pressing enter it does commit the changes. Also, instead of wrapping text, it grows the cell horizontally when the text becomes larger than the cell bounds. See the attached image for what happens. Here's the code where I register the MultiLineTextCellEditor.

    configRegistry.registerConfigAttribute(
        EditConfigAttributes.CELL_EDITOR, new MultiLineTextCellEditor(true),
        DisplayMode.EDIT, RequirementsTableConstants.COLUMN_WITH_SINGLE_ENTRY_LABEL);

The Javadoc speaks about the behavior in a subdialog. In in line mode the commit behavior is the default one. To insert a line break you need to press alt+enter.

I think that was a bug report some years ago but I forgot to update the Javadoc.

Regarding the size increase I don't know. Need to check. Raise a ticket if the behaviour should be different.

Thinking about this more you are right. The behavior should be to not commit on enter but on a key combination. That would be more intuitive and consistent with the RichTextEditor.

Please create a ticket for this behavioral change.

Will do. I also submitted a bug report for the automatic text wrapping.

The bug reports are here https://bugs.eclipse.org/bugs/show_bug.cgi?id=526607 and here https://bugs.eclipse.org/bugs/show_bug.cgi?id=526608.

Again thanks for your help and responses.
