How do I programatically make a Liferay Portlet go into Full Screen Mode

Question

I'm sure it's an easy thing, but I can't find it anywhere. How do I programatically make a portlet inside of Liferay go into Full Screen Mode. eg: the equivalent of clicking on the maximise button, but in code rather than having to make the user manually click that button.

Answer 1

You can set window state in the action phase. ActionResponse interface has method setWindowState().

You cannot change the state in the render phase -- try to imagine what would happened if two or more portlets decided to maximize themself.

• method setWindowState()
• class WindowState

Answer 2

Inside processAction(..)

actionRequest.setWindowState(WindowState.MAXIMIZED);

inside doView(..)

renderRequest.setWindowState(WindowState.MAXIMIZED);
