I am writing a pretty simple CMS on GAE, and I want my users

  • 0

I am writing a pretty simple CMS on GAE, and I want my users to be able to upload images.
I have written the part that does the actual uploading and showing the images, and here’s what I’d like to do:

Show the usual form for new posts (with a widget that contains a rich text area and a format bar for it) and the list of images the user has ever uploaded (done). Then i want an image to appear in the text area when the user clicks that image.

I generate the list of images on the server, and i can’t find a way to call any methods on the Rich Text Area from non-GWT javascript. And I don’t really want to generate the list of images by means of AJAX, because it seems quite cumbersome and, hopefully, with the advent of HTML5 it is going to be much simpler.

Well, the question is, how can i access a RichTextArea in a widget from a normal javascript on a page, or is there another way of inserting an image into it (i.e. another is there a way to generate a list of images so that they would be in a kind of widget, but without the use of AJAX).

Thank you.

    To answer your general question of getting access to your GWT code from hand written Javascript, you can use the general built in method or Ray Cromwell’s gwt-exporter project. This way, you can expose the specific methods of the RichTextArea instance you’re trying to access from external Javascript.

    As for your other question, generating a list of Images should only require getting the urls for the images and creating a bunch of Image objects with the given URLs. Then display this list in a PopupPanel or some other widget.
