gCube Quick tour guide

gCube Quick tour guide is a customizable dialogBox that can be loaded when your portlet starts up for new users. It is shipped with a built-in clickable option that allows a user to specify to not open it again.

See it in action

See Documentation (Javadoc)

gCube Quick tour guide comes with 12 different themes and is highly customizable. See some available themes in the picture below.

Adding a gCube Quick tour guide to your gCube Portlet Project

  • Get the latest gWL see wiki
  • Download the latest jar from here: gcube-quicktour.jar and add it to your build path.
  • Add the following to your project .gwt.xml file
<!-- inherits GCUBE Quick tour -->
<inherits name='org.gcube.portlets.user.guidedtour.GuidedTour' />
  • Add the following to your project web.xml file (Replace $YOUR_SERVLET_URL_PATTERN with your actual servlet url patter value)
	<!-- quicktourServlet -->
	<servlet>
		<servlet-name>quicktourServlet</servlet-name>
		<servlet-class>org.gcube.portlets.user.guidedtour.server.TourServiceImpl</servlet-class>
	</servlet>
 
	<servlet-mapping>
		<servlet-name>quicktourServlet</servlet-name>
		<url-pattern>/$YOUR_SERVLET_URL_PATTERN/quicktourServlet</url-pattern>
	</servlet-mapping>

You are ready to use it.

Show Quick tour guide at your portlet startup

In order to load the quick tour at portlet startup create a private (void) method in your GWT EntryPoint class, say you name it showGuidedTour() then you would put showGuidedTour() and the end of your public void onModuleLoad() method.


Customize Quick tour guide for your portlet

Within the showGuidedTour() method you must instanciate the GCUBEGuidedTour class (org.gcube.portlets.user.guidedtour.client.GCUBEGuidedTour)

There are several constructors you can use, allowing you to set its size, its theme, whether you want animation transitions or not and much more. Please refer to documentation to find the one that fits your needs.

As an example, see the code below: 

GCUBEGuidedTour gt = new GCUBEGuidedTour(
"gCube Framework", /* caption */
 MyClass.class.getName(),  /* uniqueid (needed for implementing the don'tShowThisAgain feature) */
 750, /* width */
 350, /* height */
 false,  /* mask (When enabled, the background will be blocked with a semi-transparent panel) */
 ThemeColor.MAGENTA /* themeColor */
);

will eventually create the following:

Adding steps to the tour

GCUBEGuidedTour supports templates(GCUBETemplate) for its steps. Although any Composite (com.google.gwt.user.client.ui.Composite) will do, we reccomend to use predefined Templates as shown in the following.

Creating Step from template

There are 3 Templates you can choose from, in each of these three the window is divided in two areas vertically.

  • GCUBETemplate1Text1Image: 

html | image
  • GCUBETemplate1Text2Image:
 
         image
 html |       
         image
  • GCUBETemplate2Text2Image:
html | image
         
html | image


According to the GCUBETemplate you choose for your step you will have to implement some methods, the following example shows how to instanciate a step with a GCUBETemplate1Text1Image as template: 

 
TourStep myFirstStep = new GCUBETemplate1Text1Image(true) {
 
			@Override
			public String setStepTitle() {
				return "What's gCube";
			}
 
			@Override
			public String setStepImage() {
                                //get the image from the web, use relative path to get it from your project
				return "//www.gcube-system.org/templates/gcube/images/logo-top.gif";
			}
 
			@Override
			public String setStepBody() {
				return "gCube is a framework dedicated to scientists. It enables the declarative and interactive creation of transient Virtual Research Environments"
			}
		};

You then need to add the step to the GCUBEGuidedTour instance created previously: 

 
gt.addStep(step1);
 
//the following would set the text vertical alignment (default is TOP)
myFirstStep.setTextVerticalAlignment(VerticalAlignment.ALIGN_MIDDLE);

and eventually show the tour on screen 

 
gt.openTour();

Complete working example

The following shows how to create a Quick Guided tour in Java. See it in action 

 
			private void showGuidedTour() {
		TourStep step1 = new GCUBETemplate1Text1Image(true) {
 
			@Override
			public String setStepTitle() {
				return "gCube Reporting";
			}
 
			@Override
			public String setStepImage() {
				return "images/tour/tour_1.jpg";
			}
 
			@Override
			public String setStepBody() {
				return "<div style=\"line-height: 19px; padding: 10px; font-size: 14px; \">" +
						"<div style=\"padding-bottom: 40px;\">" +
						"<b>gCube Reporting</b> allows users to create Reports and generate different " +
						"export formats (OpenXML, HTML, PDF) ) based on results retrieved from the infrastructure." +
						"</div>" +
						"<div style=\"padding-bottom: 40px;\">" +
						"gCube Templates are dynamically and statically completed." +
						"</div>" +
						"<div style=\"padding-bottom: 40px;\">" +
						"gCube Templates are loaded by the <b>gCube Report Generator</b> to produce actual reports." +
						"</div>" +
						"<div style=\"padding-bottom: 10px;\">" +
						"<b>Discover</b> gCube Reporting features through this quick tour." +
						"</div>" +
						"</div>";
			}
		};
 
		TourStep step2 = new GCUBETemplate1Text1Image(false) {
 
			@Override
			public String setStepTitle() {
				return "Toolbox";
			}
 
			@Override
			public String setStepImage() {
				return "images/tour/tour2.jpg";
			}
			@Override
			public String setStepBody() {
				return "<div style=\"line-height: 19px; font-size: 16px; padding: 10px;\">" +
						"<div style=\"padding-bottom: 90px;\">" +
						"<b>Define</b> your template by selecting from the Toolbox components." +
						"</div>" +
						"<div style=\"padding-bottom: 80px;\">" +
						"Choose from <b>several components:</b><br />" +
						"<span style=\"font-style: italic;\">title, headings, images, tables </span> and much more!</b>" +
						"</div>" +
						"<div style=\"padding-bottom: 10px;\">" +
						"Choose from <b>two different layouts:</b>: one column or double columns for each section." +
						"</div>" +
 
						"</div>";
			}
		};
		TourStep step3 = new GCUBETemplate2Text2Image(false) {
 
			@Override
			public String setStepTitle() {
				return "ToC & Reporting";
			}
 
			@Override
			public String setStepImage() {
				return "images/tour/tourToc.jpg";
			}
 
			@Override
			public String setStepBody() {
				return "<div style=\"line-height: 19px; padding: 10px; font-size: 16px; \">" +
						"<div style=\"padding-bottom: 10px;\">" +
						"Add a dynamic component for automatic <b>Table Of Content</b> creation." +
						"</div>" +
						"</div>";
			}
 
			@Override
			public String setStepOtherImage() {
				return "images/tour/tourFormat.jpg";
			}
 
			@Override
			public String setStepOtherBody() {
				return "<div style=\"line-height: 19px; padding: 10px; font-size: 16px; \">" +
						"<div style=\"padding-bottom: 10px;\">" +
						"<b>Format text</b> as you would in a word processor using the Formatting Bar." +
						"</div>" +
						"</div>";
			}
		};
		TourStep step4 = new GCUBETemplate2Text2Image(false) {
 
			@Override

						"<div style=\"padding-bottom: 80px;\">" +
						"Add static or dynamic <b>Tables</b>." +
						"</div>" +
						"</div>";
			}
 
			@Override

				return "images/tour/tour3_2.jpg";
			}
 
			@Override
			public String setStepOtherBody() {
				return "<div style=\"line-height: 19px; padding: 10px; font-size: 16px; \">" +
						"<div style=\"padding-bottom: 10px;\">" +
						"<b>Merge</b> table cells, add/remove rows and much more!" +
						"</div>" +
						"</div>";
			}
		};
 
		TourStep step5 = new GCUBETemplate1Text1Image(false) {
 
			@Override
			public String setStepTitle() {
				return "Sections";
			}
 
			@Override
			public String setStepImage() {
				return "images/tour/tour4.jpg";
			}
 
			@Override
			public String setStepBody() {
				return "<div style=\"line-height: 19px; padding: 10px; font-size: 16px; \">" +
						"<div style=\"padding-bottom: 70px;\">" +
						"Divide your template into various <b>Sections.</b>" +
						"</div>" +
						"<div style=\"padding-bottom: 50px;\">" +
						"Sections can be <b>imported</b> and/or <b>exported</b> from existing reports or templates." +

				}
		};
		//step1.setTextVerticalAlignment(VerticalAlignment.ALIGN_MIDDLE);
		step2.setTextVerticalAlignment(VerticalAlignment.ALIGN_MIDDLE);
		step3.setTextVerticalAlignment(VerticalAlignment.ALIGN_MIDDLE);
		step4.setTextVerticalAlignment(VerticalAlignment.ALIGN_MIDDLE);
		step5.setTextVerticalAlignment(VerticalAlignment.ALIGN_MIDDLE);
 
		GCUBEGuidedTour gt = new GCUBEGuidedTour("gCube Template Creator", TemplateCreator.class.getName(), "$MyUserGuideURL", 780, 450, false, ThemeColor.BLUE);
		gt.addStep(step1);
		gt.addStep(step2);
		gt.addStep(step3);
		gt.addStep(step4);
		gt.addStep(step5);
		gt.openTour();
	}

Advanced (I wanna write HTML)

Luckily for you GWT has introduced Declarative Layouts with UiBinder. Since this Widget supports any Composite for its steps you are free to use it to create your UI Binder Binded Steps. For more information you can look at their developer's guide.

However if you just want to avoid things like: 

 
...
			public String setStepBody() {
				return "<div style=\"line-height: 19px; padding: 10px; font-size: 14px; \">" +
						"<div style=\"padding-bottom: 40px;\">" +
						"<b>gCube Reporting</b> allows users to create Reports and generate different " +
						"export formats (OpenXML, HTML, PDF) ) based on results retrieved from the infrastructure." +
						"</div>" +
						"<div style=\"padding-bottom: 40px;\">" +
						"gCube Templates are dynamically and statically completed." +
						"</div>" +
						"<div style=\"padding-bottom: 40px;\">" +
						"gCube Templates are loaded by the <b>gCube Report Generator</b> to produce actual reports." +
						"</div>" +
						"<div style=\"padding-bottom: 10px;\">" +
						"<b>Discover</b> gCube Reporting features through this quick tour." +
						"</div>" +
						"</div>";
			}
.....

There's an easy way to do it

  • Create a class with any name you like, make it extends HTML (com.google.gwt.user.client.ui.HTML). Say this class is called IntroHTML you would have this code:
/**
  * IntroHTML.java
  */ 
package org.gcube.portlets.user.guidedtour.client.sample;
import com.google.gwt.core.client.GWT;
import com.google.gwt.dom.client.Element;
import com.google.gwt.uibinder.client.UiBinder;
import com.google.gwt.user.client.ui.HTML;
 
 
public class IntroHTML extends HTML {
 
	interface IntroHTMLUiBinder extends UiBinder<Element, IntroHTML> {
	}
 
	private static IntroHTMLUiBinder uiBinder = GWT.create(IntroHTMLUiBinder.class);
 
	public IntroHTML() {
		setHTML(uiBinder.createAndBindUi(this).getInnerHTML());
	}
} //end class
  • Create an XML file with same name of your .java class above. You must change the extension to .ui.xml. IntroHTML would have the following xml file associated (IntroHTML.ui.xml):
 
<!--    IntroHTML.ui.xml   -->
<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder">
	<ui:style>
		/* Add CSS here. See the GWT docs on UI Binder for more details */
		.important {
			font-weight: bold;
		}
	</ui:style>
	<div>
		<!-- Add HTML content here -->
		<div style="line-height: 19px; padding: 10px; font-size: 14px; ">
			<div style="padding-bottom: 40px;">
				<b>gCube Reporting</b>
				allows users to create Reports and generate different
				export formats (OpenXML, HTML, PDF) based on results retrieved from the
				infrastructure.
			</div>
			<div style="padding-bottom: 40px;">gCube Templates are dynamically and statically completed.
			</div>
			<div style="padding-bottom: 40px;">
				gCube Templates are loaded by the <b>gCube Report Generator</b> to produce actual reports.
			</div>
			<div style="padding-bottom: 10px;">
				<b>Discover</b> gCube Reporting features through this quick tour.
			</div>
		</div>
	</div>
</ui:UiBinder>
  • both your .java and .ui.xml must stay in the same package

SamePackage.png

  • your public String setStepBody() previous method would just have the following body:
 
...
public String setStepBody() {
				return new IntroHTML().getHTML();   //no more HTML in Java Strings
			}
...

Enjoy!

Advanced (I wanna write only a configuration file)

 
...
public String setStepBody() {
				return new IntroHTML().getHTML();   //no more HTML in Java Strings
			}

Adding MultiLanguage Support

If you want to give the quick tour in another language other than English, you can add as many as you wish. All you need to do is the following:

  • Add the Language you intend to support in the GCUBEGuidedTour Constructor, the following example to support Italian also.
	GCUBEGuidedTour gt = new GCUBEGuidedTour("gCube Template Creator", TemplateCreator.class.getName(), 
"http://www.myguide.com", 780, 450, false, ThemeColor.BLUE, TourLanguage.EN, TourLanguage.IT);  //add as many as TourLanguage you want here
  • Use the "ML" suffix for your GCUBETemplate instance:

NO 

         TourStep step1 = new GCUBETemplate1Text1Image(true)

YES 

         TourStep step1 = new GCUBETemplate1Text1ImageML(true)
  • Provide the tour in the languages you support, you will have to return a HashMap<TourLanguage, String> instead of a String, use TourLanguage Type as key, and the translation for the value.
			@Override
			public HashMap<TourLanguage, String> setStepTitle() {
				HashMap<TourLanguage, String> languages = new HashMap<TourLanguage, String>();
				languages.put(TourLanguage.EN, "Tables");
				languages.put(TourLanguage.IT, "Tabelle");
				return languages;
			}
