Textarea and triggerField in Ext 4.1?

[hshu]

Hello guys,
I want to make a textarea with a triggerField. But since triggerField extends from textfield, it is not easy to do. In Ext 2, there was a "defaultAutoCreate" config I could override and change the textfield into a textarea.

But how to do this in Ext 4.1? The only way I see is to create my custom triggerField class so that it extends from textarea.

Also, instead of extending from textarea, another alternative would be to somehow make a textfield display multiple lines, but I can't figure that out. ('\n' and '<br/>' won't work)

Thoughts? Thanks in advance!

What would happen after the trigger .. update the current line? You could always create a container with a button in a hbox layout ...

Also .. Both triggerfield and textarea extend from textfield. You could create your own widget.

Hi Scott,
Thank you for your reply!
The trigger will open up something like a to-do list (one thing each line).
I don't want all my to-do things to be in a single line, that's why I need a textarea.

Currently, my solution is to create my custom triggerTextArea class. It copies all the source code of Ext.form.trigger. The only difference is that it extends from Ext.form.TextArea.
So this solution is not a good way of code reusing (too much duplicate code.)
Is there a better way?

Also can you elaborate on "a container with a button in a hbox layout" ?
