Full page zoom
Full page zoom (or just fullZoom) is a new feature in Firefox 3.
Example (XUL:browser)
The following example demonstrates the use for the current focused browser window. This is the typical usage for a Firefox extension.
js
var zoom = ZoomManager.getZoomForBrowser(gBrowser.selectedBrowser);
ZoomManager.enlarge();
ZoomManager.setZoomForBrowser(gBrowser.selectedBrowser, ZoomManager.MIN);
Example (XUL:iframe)
Note: This is probably out of date.
You may use the fullZoom feature for a <XUL:iframe>
as well. However, because an iframe doesn't have a markupDocumentViewer property, we need to get that first:
js
var zoom = 1.5;
var iframe = document.getElementById("authorFrame");
var contViewer = iframe.docShell.contentViewer;
var docViewer = contViewer.QueryInterface(
Components.interfaces.nsIMarkupDocumentViewer,
);
docViewer.fullZoom = zoom;
