I'm still confused here. Maybe I didn't spell out things. I have
more details on this question here:
http://stackoverflow.com/questions/8580225/how-to-set-a-presenter-in-a-composite-widget-in-gwt
Basically, I'm using clientFactory to bind an Activity(Presenter) to a
viewImpl. I have a viewImpl and in the ViewImpl.ui.xml I have a
reference to a widget class: MUpld, which contains a gwtUpload widget.
I have a fileUploadServlet defined in the web.xml that gets called
when the file upload starts. The servlet gets data from the widget
and returns it back to the MUpld class, which is the composite widget,
nested into
the ViewImpl.ui.xml file. Everything is in place, but now, I need
some way to get the instance of the Presenter, the Activity class that
the clientFactory created and bound the view, from inside the
composite widget.
It's probably really simple, I'm just not still seeing how to do it.
I'm using GWT 2.4 and the last project I worked on, we just used GIN
to inject the presenter into the composite widget. I may have to
rewrite this to add GIN
in and take out the clientFactory, I was just not wanting to do that
for sake of time as I have setup GIN in an app before.
My composite widget class is defined in the viewImp as:
@UiField = MUpld mUpld;
and in hte MUpld class I define a handler, using an inner class in the
constructor like so:
public MUpld() {
IUploader.OnFinishUploaderHandler onFinishUploaderHandler = new
IUploader.OnFinishUploaderHandler() {
public void onFinish(IUploader uploader) {
if (uploader.getStatus() == Status.SUCCESS){
...
//
presenter.setRowDataList(rowData);
}
}
};
initWidget(uiBinder.createAndBindUi(this));
uploader.addOnFinishUploadHandler(onFinishUploaderHandler);
