I am using GWTUpload , the library is in here
https://code.google.com/p/gwtupload/
The Example code at client side found on that website has this structure:
// Attach an image to the pictures viewer
private OnLoadPreloadedImageHandler showImage = new
OnLoadPreloadedImageHandler() {
public void onLoad(PreloadedImage image) {
//showImageFlowPanel code solution 1
image.setWidth("75px");
showImageFlowPanel.add(image);
}
};
private IUploader.OnFinishUploaderHandler onFinishUploaderHandler = new
IUploader.OnFinishUploaderHandler() {
public void onFinish(IUploader uploader) {
if (uploader.getStatus() == Status.SUCCESS) {
new PreloadedImage(uploader.fileUrl(), showImage);
UploadedInfo info = uploader.getServerInfo();
String headShotImageUrl="http://"+Window.Location.getHost()+"/"
+"images/uploaded/"+info.message;
//headShotImage code solution 2
if(!"".equals(headShotImageUrl) &&
UriUtils.isSafeUri(headShotImageUrl)){
headShotImage.setUrl(UriUtils.fromString(headShotImageUrl));
}
}
}
};
The example uses showImageFlowPanel (solution 1) to store the image but I
want to store the image inside headShotImage which take the url after user
uploaded image successfully, see the headShotImage (solution 2) code above.
Ok, the headShotImage code work fine but I dont know how to remove it when
users remove the image. If I use showImageFlowPanel as in the solution 1
then the program remove the image automatically for me and I do not need to
do anything.
So my question is "*Where to call an Action when user remove an uploaded
image in GWTUpload?*"
