getInnerHeight and getInnerWidth in ExtJS4

We are using getInnerHeight and getInnerWidth methods in our application.Now we a开发者_运维知识库re migrating to ExtJS4. As per my Observation, these two methods are not there for panel.

Is there any thing replaces these two methods?

if you need the body width/height(without header, dockeditems etc...)try this:

var height = Ext.getCmp('panelId').body.getHeight(true);

Why are you using innerHeight and innerWidth? You can get the height/width of the element that the Ext.Panel is rendered to as follows...

var height = Ext.getCmp('panelId').getEl().getHeight();

This should suffice unless you've got massive amounts of padding on your panel.

Pass boolean true as parameter for the getHeight() function. So you get:

var height = Ext.getCmp('panelId').getEl().getHeight(true);
