How to switch display mode of table cells? [message #1017009]

Hi,

so far I did not find out how the nattable, its layers, config or ui bindings must be configured to control the edit/normal mode switching.

How can I configure a certain cell to become editable by mouse click or key event? What are the steps to take?

Take a look at the documentation here

I did that (register th editable rule and the editor) but I still miss the point where a cell is being 'activated' for editing by some event. Where is that done or configured? Which layer is responsible for this? Clicking on a cell configured as alwalys_editable does nothing but select it.

There is no special layer needed to enable editing in NatTable. Everything is done via configuration.

The default cell editing configuration is provided by the DefaultEditConfiguration that is used by the DefaultGridLayerConfiguration.

If you want to change the default behaviour you have to create your own configuration and add it to your NatTable instance.

The EditableGridExample is a good place to look at.

Regarding your name I suppose you speak German. So you can also have a look at my articles where I explained how to get started: http://eclipse.org/nattable/documentation.php?page=articles

If you added a configuration that tells a cell to be editable but it doesn't either your label to set the editable mode is not attached or the configuration is not applied.

Well, using the DefaultGridLayerConfiguration causes a weird ClassCastException. I am not sure whether this is a bug or some other problem since I have seen very few exceptions thrown in line 1 of a class.

But I collected the necessary information from the code to make my cell editable on double click, which is enough for the moment.

Good guess. I already read the articles as a starting point for my explorations. Thanks for your help.

Hi,

well if you read my articles, have you also looked at the examples attached? There I'm using an additional configuration for editing instead of reusing the DefaultGridLayerConfiguration.

If you want to reuse the DefaultGridLayerConfiguration you need to know that it is a layer configuration. If you are trying to add it to the NatTable directly, you will get the posted exception. You need to add it to the GridLayer instead.

But I always suggest to create a new edit configuration to avoid any dependencies on existing stuff.

Greez,
Dirk

Thank you for this hint. I took a brief look and have a simple question:

The advanced examples seem to derive from the time when nattable was not an eclipse incubator project. Why are there two example TreeLayer implementations? Was the TreeLayer as it is part of the 0.9.0 release not part of the project at that time?

Are there any changes to the tree thing coming up in 1.0.0?

There aren't! Do you talk about TreeGridLayer and TreeGridLayer2 in my examples? The difference between these two implementations is the different PersonWithAddressTreeFormat
These are special implementations for my examples and are not special to NatTable core. In fact they are using the TreeLayer. That's a difference! Smile

Despite several bugfixes nothing I'm aware of.
