design help on a skin: how should I reference another component
I attached a line numbering component and its skin. At the moment, I have to
tell the line number component which component to "number" by setting the
"ruled" property. I would like to have that automatically detected or set
via a object reference in bxml.
Right now, the way to use this is:
<BoxPane orientation="horizontal">
<NumbersRuler />
<TextArea bxml:id="text"/>
</BoxPane>
I have tried unsuccessfully to have <NumbersRuler ruled="$text"/> but I keep
getting a bxml error about text not being a component. Should this reference
have worked?
Here's the error:
An error occurred while processing atest.NumbersRuler starting at line
number 61:
java.lang.IllegalArgumentException: Unable to coerce java.lang.String to
class org.apache.pivot.wtk.Component.
There are two other approaches to automatically have this done.
a) Be notified once BoxPane is completely loaded. Then numbers ruler
could find any text area peers and use that as the ruled component. But I
have not found a reliable way to detect when BoxPane has finished being
fully loaded. I like this approach but I do not see any way to know when the
BoxPane has fully loaded.
b) Make the text area a child of the numbers ruler. Use containment to
make it easier to set. But then I have to manage the text area child in
layout and perhaps the ruler would want to be separated from the text area
by another line ruler/decorator. So this is not a great solution future-use
wise.
Is there a better way?

That looks like a useful scrollpane property J Now I understand your comment
about a column/row header.
Thanks!

Sure - see below:
<ScrollPane>
<TextArea bxml:id="textArea"/>
<rowHeader>
<NumberRuler ruled="$textArea"/>
</rowHeader>
</ScrollPane>

You need to declare the TextArea before the ruler - otherwise, the "text"
variable will not have been initialized (the same applies to local variables
used in a procedural language - you have to define them before you can refer
to them).
In practice, this generally isn't an issue because you would put the text
area (view) and ruler (column or row header) in a scroll pane and declare
the view first.

Can you show me what you are saying in bxml? Yes, these things are plopped
into a scrollpane, but I am not sure how you would declare it first since it
needs to be to the left of the textarea.
