Hi all,

I want to upload single image file then displaying it in a Control (Label ?). Then when user submits the form I want to save the file somewhere. I also want to be able to prevent user from uploading other file type.

From what I understand I can use FileUpload or FileDialog, but which one is the most suitable for this use case ?

Any advice would be greatly appreciated.

Thanks & Regards,
SetNug

Hi Team,

I've decided to use FileUpload widget, but I've faced another problem.

On FileUploadReceiver#receive I put some code to update Label widget with the uploaded image in UI thread within Display#syncExec. But the image won't get shown unless I click the label area or drag around the FormDialog that contains the Label.

Upon debugging I found that the execution halts forever at Display#syncExec and eventually at RunnableLock#wait in Synchronizer#syncExec.

Any help would be greatly appreciated.

Thanks & Regards,
SetNug

I would use asyncExec if the calling thread doesn't need to block.

The updating issue sounds like you need to open a ServerPush session so the UI updates can be sent to the browser without a user performing an action. Have a look at org.eclipse.rap.rwt.service.ServerPushSession
