TextArea loading from a file

[Aanjaneya Shukla <aa...@vmware.com>]

Hi,
I am trying to load a text file from json into the window as
JSON:
{
Text:"@sample.txt"
}
BXML:
<TextArea text="%Text"/>

So instead of loading the text into the TextArea from the file sample.txt, it only it shows '@sample.txt' as the text in the TextArea. 

Same logic works fine for images.

Thanks

I understand. However, that syntax only works in BXML files. It does not work in resource (JSON) files.

If the file name can change at runtime, you probably wouldn't want to put it in a resource file anyways, since resources are static and generally read only once at application startup. You could do this:

<TextArea text="$textLocation"/>

Then, before you read the BXML file, you can call:

bxmlSerializer.getNamespace().put("textLocation", new URL(...));

Then the text will be set to the contents of the file specified by the given URL.

What I was trying to achieve was that my bxml pulls that text written in json and since it has '@' symbol so convert it to URL.
For example,
JSON:
{
Image:"@image.bmp"
}
BXML:
<ImageView image="%Image"/>

So in the above case the image is displayed. But when I try this,
JSON:
{
Text:"@sample.txt"
}
BXML:
<TextArea text="%Text"/>
In this, only '@sample.txt' is displayed. But the aim was to display the text in sample.txt file. 
So can the latter case be modified in such a way that I have the contents in the file as the text in my textarea. I don't want to declare the file location in my bxml as the file name to be loaded may change during runtime.

The @ symbol is only converted to a URL when reading a BXML file. It doesn't work in a JSON file. You'll need to put your localized text in the JSON file itself.
