java wickets menu on image button

[ASHU_JAVA]

I'm trying to create a image button. When this button clicked, a drop down
menu should appear with External Links to other websites.

Till now, I've managed to create drop down menu with External links but on
navigation bar as provided in example:
http://tomaszdziurko.pl/2012/03/wicket-and-twitter-bootstrap-navbar/. 

HTML: 
 
Code:
public Builder withMenuItemAsDropdown(MenuItemEnum menuItem, String
pageToLink, String label) {
//BookmarkablePageLink link = new
BookmarkablePageLink("link", pageToLink);
   ExternalLink linkExternal = new ExternalLink("link", pageToLink,
label); 
   linkExternal.setBody(new Model(label));
   linksMap2.put(menuItem, linkExternal);

return this;
}

And then in Base JAVA class:
add(new TwitterBootstrapNavBarPanel.Builder("navBar", HomePage.class,
"Example Web App", getActiveMenu())
.withMenuItem(MenuItemEnum.CLIENTS, ClientsPage.class)
 .withMenuItemAsDropdown(MenuItemEnum.PRODUCTS2, "Sample_URL", "Product 1")
.withMenuItemAsDropdown(MenuItemEnum.PRODUCTS2,  "Sample_URL",
"Product 2")
.withMenuItemAsDropdown(MenuItemEnum.PRODUCTS2,  "Sample_URL",
"Product 3")
   .build());


Now to add a Image, I've added the code:-

final ContextImage image=new ContextImage("image","IMAGE.png");
ExternalLink link = new ExternalLink("link", "SAMPLE_URL");
 //Image image = new Image("img", new
SharedResourceReference(BasePage.class,
"/wicket-bootstrap/img/QuestionMark_2.png"));
 link.add(image);
 add(link);

But I'm unable to add the drop down menu to this Image button. Kindly
suggest some inputs.

Thanks in advance.

Re: java wickets menu on image button

[ASHU_JAVA]

Hi Martin,

Thanks a lot for your suggestion.

My requirement is nearly complete, the only issue I'm facing right now is
*how to open the List link in new tab ?*.
Please find below my current code:

/SamplePage.Java/
add(new LinkPanel("navBar"));

/SamplePage.html/


/LinkPanel.Java/



/LinkPanel.html/



/style.css/



The output looks like below image:
 

So, when I click on link it open in the same window. 

I tried to change the *"LinkPanel.java" *code as below:-

The output now looks like below image:
 

I'm able to now open the links in different tabs but the appearance is now
not in the list.

I think if the LinkPanel.Java code can generate an HTML like below it will
become perfect according to my requirement:-


Kindly suggest inputs on how to achieve it in my current code.
Thanks in advance.




You need to add the dropdown to the  element.
In the blog article you mentioned in your first email this is:  

The blog uses:

 <#> 
 **

   
 
   
 

You need to remove * and use   instead of .
In the Java code replace:

itemContainer.add(new Label("label", currentMenuItem.getLabel()));

with

itemContainer.add(new ContextImage("img", ...));

Hi Martin,

I've implemented the External Links as shown in below code


Can you please suggest how to provide a Pop-up if the External link doesn't
work i.e. if a link is clicked and the link is an invalid URL, it should
open a pop-up with error message instead of a new tab?

Thanks in advance.

Java Wickets Delete Multiple Entries CheckboxGroup

[ASHU_JAVA]

Hello All,

I've been using CheckBoxGroup in my application and followed the below
example URL:-
http://examples7x.wicket.apache.org/compref/wicket/bookmarkable/org.apache.wicket.examples.compref.CheckGroupPage;jsessionid=A65260928022BEDC4A2943D0F5FD6996?0

  

I need to remove single, multiple or all entries from database by selecting
checkbox.

 

On clicking the delete button, I was able to fetch the corresponding entries
like "Manoj", "Neeraj" and then I performed below operation in my panel:-



For first username record, deleteUserStoreDomain() method return TRUE but
for each next username record it returns FALSE.

Thus, I'm unable to perform 'multiple' and 'all' username records deletion.

Kindly suggest solutions for this issue.
Thanks in advance.

Java Wickets Refresh Model Window

[ASHU_JAVA]

Hello All,

I'm having a table containing a button on each row.
Onclick of this button, a model window appear, providing user two options,
either use text field for single record or upload a file for multiple
records and then click "Add Details" button to save the record(s) in
database.

The issue is if a user enter data in text field OR upload file then the user
input's reference remains existent even after the clicking of "Add Details"
button.
Thus, the data remains present and if the user clicks on "Add details"
button again, it executes the last performed operation again "single record
entry using text field input" OR "multiple record entry using File upload".

What I want to achieve is to refresh the model window after clicking the
"Add details" button, remove the reference of last executed operation and
make sure that the user enter the text field or upload the file again to
repeat the ADD DETAILS operation.
Currently I've to close the model window and refresh the Parent page to
reload everything.

The Page view looks like the below attached image.

 

Can anyone please share some input to achieve this functionality?

thanks in advance.

Re: Message Scroll Banner in Wickets

[ASHU_JAVA]

Hello Martin,

I'm trying to use  "Jquery Marquee"
to implement the required
functionality.

I've made an  HTML sample    (JSfiddle),
which is working fine but I'm unable to replicate the same in Java Wickets.

Here's my code:-

HomePage.html




HomePage.Java

add(new MyPanel("newsDetails"));

MyPanel.Html


http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>



 














 







MyPanel.Java

public class MyPanel extends Panel {

private static final long serialVersionUID = -7322692526459024428L;
@SpringBean(name = "manageMyApplication")
protected ManageMyApplication manageApp;
private List list;

public MyPanel (String id)
{
super(id);

RepeatingView repeatingView = new RepeatingView("news");
List results = getAllItem(); //Getting List from 
database
if(results!=null){
MyBeanvalues = results.get(0);

if(StringUtils.isNotEmpty(values.getList1())){
repeatingView.add(new
Label(repeatingView.newChildId(),values.getList1()));
}
if(StringUtils.isNotEmpty(values.getList2())){
repeatingView.add(new
Label(repeatingView.newChildId(),values.getList2()));
}
if(StringUtils.isNotEmpty(values.getList3())){
repeatingView.add(new
Label(repeatingView.newChildId(),values.getList3()));
}
}
  
   add(repeatingView); 
 }

  
}

MyResourceInitialize.java file contains javascript reference to load:

@Override
public void renderHead(final IHeaderResponse response) {
response.renderJavaScriptReference(new
JavaScriptResourceReference(LocateResources.class,
"js/vendor/jquery.marquee.min.js"));

response.renderJavaScriptReference(new
JavaScriptResourceReference(LocateResources.class,
"js/newMarquee.js"));
super.renderHead(response);
}

The Javascript code has been added to "newMarquee.js" file as given below:-

$(function () {
$('.marquee').marquee({

duration: 15000,
duplicate: false,
delayBeforeStart:2000,

allowCss3Support: true,
gap: 600,

});
});


But the issue is the Javascript file "newMarquee.js" and the css mentioned
in MyPanel.html fails to load.
I've tried using AjaxEventBehavior to append Javascript in Wickets code but
that too didn't work.

Can you please share some inputs on how to achieve this?
Thanks in advance.

Re: Message Scroll Banner in Wickets

[ASHU_JAVA]

Hello Martin, 

I've added alerts on newMarquee.js file and they didn't get executed. 
By not loading, I meant to say no CSS style effects and Javascript method
for marquee gets executed.

I don't receive any error.
The HTML just display the mypanel content as a list instead of scrolling
marquee. 

Please share your inputs.

Hello Martin,

Ok, I've corrected the error (*missing :*) on loading the newMarquee.js.
But even after successful loading of "newMarquee.js" (I've checked with
alert), no marquee appears(as shown in below image) :-
 

It will just display it as normal List Items.

The HTML generated is as shown in below image:-

 

Can you please share some inputs on how I can make the Javascript
(newMarquee.js) and CSS (MyPanel.html) execute successfully in a wicket
Panel?

Re: Message Scroll Banner in Wickets

Hello All,

I've resolved my issue by overriding the renderHead() method inside
MyPanel.java as below:-

@Override
public void renderHead(IHeaderResponse response) {

response.renderString("");
response.renderOnDomReadyJavaScript("$(function () { 
$('.marquee').marquee({ duration: 15000,duplicate: false,
delayBeforeStart:2000,  allowCss3Support: true, gap: 600, pauseOnCycle: true, 
pauseOnHover: true });});");

} 

Thanks everyone.
