I have a variable, x, which I want to update when the content of 
a DlangUI EditLine is modified. I tried making this work with the 
"onContentChange" method listed in the API documentation, but dmd 
told me it's not there. I've got this 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
