Re: [NEWBIE] How to do if... else... switch... in wicket html ?

2009-03-17 Thread Linda van der Pal 
You don't do it in the HTML, but in the java code. So you create a 
component that takes care of the if-else for you.

Hi,

What is the best technique to do some if else and so on with wicket ?

I need a html with something like that (stupid and naïve approch) :

wicket:if (something = toto)
 div do this thing/div
wicket:else if (something = foo)
 pa href=error.htmlIt's not good/a/p
wicket:else if (something = other)
 divrender other/div

How to do that with wicket ?

Thanks.

2009-03-17 Thread francisco treacy 
div wicket:id=text/div

String text;
if () {
text = ...
} else text = ...

add(new Label(text, text))

if you need different hierarchies (i.e. not just one Label), then use
Panels or Fragments instead

 wicket:if (something = toto)
  div do this thing/div
 wicket:else if (something = foo)
  pa href=error.htmlIt's not good/a/p
 wicket:else if (something = other)
  divrender other/div

Here is one thing you can do:

div wicket:id=my_first_optiondadada/div
div wicket:id=my_second_optiondududu/div

And in your Java code you do:

boolean showDadada;
add(new WebMarkupContiainer(my_first_option).setVisible(showDadada));
add(new WebMarkupContiainer(my_second_option).setVisible(!showDadada));

This is only one of the numerous possible ways to accomplish this..
but remember: no script-coding in HTML!

Hi,

You can use in your Java code

if (something.equals(error) {
   setResponsePage(ErrorPage.class);
   return;
}

commands in the error case to forward the user to the Error page.

Hi,

Use panels, and instantiate either one type or another on the java side. 
Then your content will change.


Cheers,

It sounds like you want something like this:

File.html:

div wicket:id=labeldadada/div


File.java:
boolean again = false; // put your logic here
if (again) {
   add(new Label(label, Very well!);
} else {
   add(new Label(label, Very good!);
}

Yes, I see there is planty solutions, but I am a little losted.

I understand very well the WebMarkupContainer and the setVisible mecanism.

But I don't undestand very well where is the markup in
WebMarkupContainer... for instance, I have :

div wicket:id=my_first_optiondadada/div
div wicket:id=my_second_optiondududu/div

and I should want in my_first_option :
p Very Good ! /p

and for second :
div span wicket:id=again?/span Very Well ! /div

NOT in java prose, but in a HTML file.

Where do I put that ? In some wicket fragment ? Other ?

Thanks again, I'm going to try all that.

I should prefer than Very well and Very good are in a html file,

For instance, something like :
add(new Panel(label, a reference in a wicket html file);

Then you do indeed have to work with the visibility.

 I understand very well the WebMarkupContainer and the setVisible mecanism.

 But I don't undestand very well where is the markup in
 WebMarkupContainer...

There is no difference whether the div's are visible or not.

If you insert components within them, you just add normally:

WebMarkupContainer dadaDiv = new  WebMarkupContainer(my_first_option);
page.add(dadaDiv);
dadaDiv.add(new Label(my_span));

.. and  so-on.

If you want the WebMarkupContainer to be a panel, no problem, it can
be a new Panel(my_first_option); as well.

Simply try-it-out and show us your code if you cannot make it work.

2009-03-17 Thread Brill Pappin 
Ok, I an see where this would help if you have separate designers and  
programers. Try this way then:



Label veryGood = new Label(my_first_option, Very Good!);
Label veryWell = new Label(my_second_option, Very Well!);
Label again = new Label(my_second_option, ?);
add(veryGood);
add(veryWell);
veryWell.add(again);

bool = expression[1|0]...
veryGood.setVisible(bool);
veryWell.setVisible(! bool);


and your HTML will be simply:

div wicket:id=myComponent[replaced label]/div

p wicket:id=my_first_option[Very Good ! ]/div
div wicket:id=my_second_optionspan wicket:id=again[?]/ 
span[Very Well !]/div


Note: I haven't tried nesting a label inside another label, but things  
usually work that way in Wicket. If the label doesn't work, you can  
try a MarkupContainer instead, which is pretty much the same thing,  
just not specifically a Label (you might need to wrap both string as  
labels in that case).
I'm not sure why you would want that again component though from the  
example it doesn't seem to need to be a component.

It's work ! (I hope).

I do that :

  body
div wicket:id=copie?/div
  /body

  wicket:fragment wicket:id=frag-diap
Diapositive
  /wicket:fragment
  wicket:fragment wicket:id=frag-expo
Exposé
  /wicket:fragment

in java : add(new Fragment(copie, frag-expo, this)); // or frag-diap

And I get :

  body
div wicket:id=copie
That is exp frag
  /div

  /body

I lookat all your other solution ; infinitely numbers of thanks.
