Any profile application can open and use JomSocial popup window. There is 3 simple JavaScript function that you can use.

function cWindowShow(windowCall, winTitle, winWidth, winHeight);
function cWindowActions(action);
function cWindowHide();

cWindowShow does not know how to fill up the window. It is your responsibility to pass a function, (windowCall) which cWindow will simply execute. In most cases, windowCall would simply be a ajax call, which in turn will try to fill assign 'cWindowContent' id with html data.

Opening a popup window

Example

var ajaxCall = 'jax.call("community", "plugins,walls,ajaxSaveWall")';
cWindowShow(ajaxCall, 'Compose', 450, 300);
