I have a variable, x, which I want to update when the content

working now by implementing a custom subclass of EditLine as
below:
class XEditLine : EditLine
{
this(string ID, dstring initialContent = null)

super(ID, initialContent);

override bool onKeyEvent(KeyEvent e)
{
super.onKeyEvent(e);
x = to!double(this.text);
return true;

This works but it seems like there should be a cleaner way to
do this, any suggestions? Thanks.
You can either override onContentChange or use
onContentChangeListener
override void onContentChange(EditableContent content,
EditOperation operation, ref TextRange rangeBefore, ref TextRange
rangeAfter, Object source) {
super.onContentChange(content, operation, rangeBefore,
rangeAfter, source);
// do something
x = to!double(this.text);
}
or
EditLine line = new EditLine();
line.onContentChangeListener = delegate(EditableContent) {
// do something
x = to!double(line.text);
}

If you don't see onContentChange method, probably you have older
version of DlangUI. Try dub upgrade --force-remove
