Migrate custom css from Ext GWT 2.x to Ext GWT 3.x
I'm trying to migrate our Ext GWT 2.x css-files to Ext GWT 3.x. For EXT GWT 2.x we customized the styles via a new theme css file. If possible we want to reuse this theme css file for customizing the styles in EXT GWT 3 as well.
Now, with the Appearance Pattern I can't detect a possibility for an easy switch. Do I have to support every UI-Element that I want to customize (for example FieldLabel) with a corresponding Appearance Implementation (MyFieldLabelAppearance implements FieldLabel.FieldLabelAppearance)? If not, can you please give me a hint?
Thanks in advance
