There is a "setWindowState()" method that is part of the javax.portlet.ActionResponse interface. So, its really a matter of getting a hold of an "action response" object. The "action response" object is an interface implemented in Liferay by the same object that implements the javax.portlet.PortletResponse interface, which in turn can be retrieved from the external context's getResponse() method. So, for JSF, you are looking at:




   FacesContext facesContext = FacesContext.getCurrentInstance();

   javax.faces.context.ExternalContext externalContext = facesContext.getExternalContext();

   javax.portlet.PortletResponse portletResponse =
        (javax.portlet.PortletResponse)externalContext.getResponse();

   javax.portlet.ActionResponse actionResponse =
        (javax.portlet.ActionResponse)portletResponse;

   actionResponse.setWindowState(javax.portlet.WindowState.MAXIMIZED);

Thanks for your reploy Joel. I found that very usefull.
Is there any api manual which explains how to use portal libraries. Until now I have found just the api but It hasn't too much explanations.

Unfortunately, no. The lack of JavaDocs is a screaming hole in the Liferay code base. The only thing you can do is study the source code. Lots of "poking around." The lines of code I gave you was about 3 hours of my personal searching I had done several months ago.

While the above quote is true (Liferay desparately needs Javadocs), I should point out that in this particular instance, virtually all of the code in the sample is using JSR168 portlet API code. NONE of it is Liferay code. Don't forget that when programming portlets, there is a lot of documentation out on the net regarding portlet development in general.

One resource I found helpful early on was the on-line book on portlet development: http://www.manning.com/hepper/

I've another question may be you have fight with this before. I've another page wich needs to have a back button arrow instead a minimize arrow. Is there any way to achieve this programatically.

Thanks, for your reply

Hi Arun,

It seems that you are trying to set the window state at the render phase of the portlet.
This isn't possible, window state and portlet mode may only be changed at the portlets process action phase.

Therefore it can either be done at the portlets processAction method or at a jsf action method if you are using JSF.

Using the Portlet 2 API it is also possible to set the portlets window state and mode using events.

Best regards

Tobias

Hi,

this is not possible the way you want to do it right now.

I have a more or less working solution for the issue.

First you have to get the maximizing url of your portlet. I did that by extending the JSF portlet class and storing the value in the session as attribute:

public void render(RenderRequest renderRequest,
        RenderResponse renderResponse) throws IOException, PortletException {
            PortletSession pSess = renderRequest.getPortletSession();
            PortletURL maxUrl = renderResponse.createRenderURL();
            maxUrl.setWindowState(WindowState.MAXIMIZED);
            log.debug("The maxUrl: " + maxUrl.toString());
            pSess.setAttribute("maxUrl", maxUrl.toString());
}


In your portlets you can then get the session and extract the max URL. In your JSF page you can then create an external link which will maximize your portlet.

Please note that you cannot navigate to a different JSF page in this case...

kind regards
Tobias

Hi All,


Thanks Gindler and Amon for your reply . Sorry for the delay.I will try to explain my problem in detail.

I am using liferay 5.2 +icefaces 1.7.2 combination.

in the left hand side of the page ,i have a Link portlet which contains two links. say Link-one and Link- two.
In the right hand side of the page i have two portlets A and B.

on click of the Link-one in the left hand side portlet i need to minimize portlet B and maximize portlet A.
on click of the Link- two. in left hand side i need to minimize portlet A maximize portlet B.

right now i am using IPC provided by ice faces and able to re-render potlet A and portlet B from left portlet.
But the problem is with minimizing and maximizing the portlet A and B. Since this is not an action event.

OR
i want to HIDE the portlet in the right hand side based on the link i clicked.

i will place two portletes on right hand side i need to HIDE one and SHOW another based on the link click in left hand side portlet .
is it something called (WINDOW SHADING) ?. Please advice

Thanks,
Arun R K

Hi,

my solution should work in your scenario.

When the IPC-method on portlet A is called, simply get Portal A's Max-URL and make a redirect to this page. All other portlets on the page will be hidden, even the Link Portlet. So you don't have to minimize Portlet B in this case.

kind regards
Tobias
