Setting the text color of the tree label provider [message #419523]

Hello,

I have a custom AdapterFactoryLabelProvider for my EMF tabletree. I
customize the text with no problem, however I want to set it's color. I
cannot use it in public String getColumnText(Object object, int
columnIndex) because the function returns only a String.
How can I change the text color? Do I need to overrite another function
in another class?

Thanks,

Mircea

Your LabelProvider has to implement ITableColorLabelProvider and then
you can control the color. I don't know if AdapterFactoryLabelProvider
already implements this none mandatory interface.

Would you happen to know in which plugin this interface might be? I
didn't find it in the source code of the eclipse plugins.

It's ITableColorProvider.

Mircea,

Note that AdapterFactoryLabelProvider.ColorProvider will help. Perhaps
you'll want your item providers to support ITableItemColorProvider;
you'll need to declare that in your adapter factory too and you'll
likely want to update the plugin.xml registration to indicate your
factory supports that...

Thanks Ed,

What I did was to implement the ITableColorProvider. It works fine (I
have a CustomAdapterFactoryLabelProvider that extends
AdapterFactoryLabelProvider and implements ITableColorProvider).
What fundamental difference would the method you described have vs
implementing the ITableColorProvider interface?

That's exactly what the existing (in EMF 2.4) class does.

Like the IItemLabelProvider interfaces, it delegates control of the
colors to the item providers themselves so that each generated item
provider can control the colors directly.
