GCube Widgets Store

gCube Widgets Store

This page lists the available (reusable) GWT Widgets that developers can integrate in their GWT Projects/portlets if they need to.

Every Widget listed is provided with a screenshot and instructions on how to integrate it.

Available Widgets:

Select the Style

If you want to use the default style just skip this. If you want to use the GXT style instead you have to add the following directive to your WebApp main css stylesheet:

@import url('$MODULE_NAME/old-dialog.css');

Where $MODULE_NAME is the name of your gwt module: example:

if you open your gwt.xml file the module name is the value of the rename-to attribute

<module rename-to='myapplicationname'>

then you would add at the top of your application main css stylesheet the following:

@import url('myapplicationname/old-dialog.css');

Use this widget to display a dialog containing the possibility to upload a file on server with an actual progress of the current uploaded file in percentage; To get to know which file was uploaded listen for the {@link FileUploadCompleteEvent} on the {@link HandlerManager} instance you will have to pass to this widget.

				String fileName = event.getUploadedFileInfo().getFilename();
				String absolutePathOnServer = event.getUploadedFileInfo().getAbsolutePath();
				GWT.log(fileName + " uploaded on Server here: " + absolutePathOnServer);
 
				//just for this example the timer is just to pretend you are doing something with the uploaded file on the server, wait 3 seconds
				Timer t = new Timer() {
 
					@Override
					public void run() {
						dlg.showRegisteringResult(true); //or false if an error occurred	, you must call this method once the upload is finished and you're done processing the file on the server
