Re-sizing form content to fit browser window - Using Card Layout - extjs4

Question

I need the tab-panels to fit browser window size. I have used card layout, and it is not re-sizing to fit the browser window. I think i'm missing some properties in my viewPort.
launch: function() {
Ext.create('Ext.container.Viewport', {
layout: 'card',
items: [
{
xtype: 'panel',
items: { xtype: 'tabP1' }
},
{
xtype: 'panel',
items: { xtype:'tabP2' }
}
,
{
xtype: 'panel',
items: { xtype:'tabP3' }
}
]
});
},
2.) One of my tabpanels; I am using absolute layout. I am using this layout because it's easy to set form components where i ever i desire it to be. Therefore, i would like a solution that works with the same layout.
Ext.define('MyApp.view.MyForm', {
extend: 'Ext.form.Panel',
alias:'widget.tabP1',
// height: 250,
// width: 726,
layout: {
type: 'absolute'
},
bodyPadding: 10,
title: 'My Form',
initComponent: function() {
var me = this;
Ext.applyIf(me, {
items: [
{
xtype: 'gridpanel',
title: 'My Grid Panel',
columns: [
{
xtype: 'gridcolumn',
dataIndex: 'string',
text: 'String'
},
{
xtype: 'numbercolumn',
dataIndex: 'number',
text: 'Number'
},
{
xtype: 'datecolumn',
dataIndex: 'date',
text: 'Date'
},
{
xtype: 'booleancolumn',
dataIndex: 'bool',
text: 'Boolean'
}
],
viewConfig: {
}
}
]
});
me.callParent(arguments);
}
});

UPDATE 2
launch: function() {
Ext.create('Ext.container.Viewport', {
layout: 'card',
items: [
{
xtype: 'tabP1'
},
{
xtype:'tabP2'
}
,
{
xtype:'tabP3'
}
]
});
},
onSuccess: function() {
this.getViewport().getLayout().setActiveItem(1);
},
I get an error when i use your code, saying that this.getViewport().getLayout().setActiveItem(1) is not a function. I think this is because i used border layout. How can i resolve this ?

Your problem is "over-nesting" Why are you putting 'tabPFoo' inside a panel with no layout? They are at best, redundant, also causing the layout system to spend more cycles when it's not needed.
Ext.require('*');
Ext.onReady(function(){
var vp = new Ext.container.Viewport({
layout: 'card',
items: [{
xtype: 'grid',
store: {
fields: ['name'],
data: [{
name: 'Name 1'
}]
},
columns: [{
flex: 1,
dataIndex: 'name',
text: 'Name'
}],
listeners: {
itemclick: function(view){
var grid = view.ownerCt,
next = grid.nextSibling();
vp.getLayout().setActiveItem(next);
}
}
}, {
xtype: 'grid',
store: {
fields: ['name'],
data: [{
name: 'Name 2'
}]
},
columns: [{
flex: 1,
dataIndex: 'name',
text: 'Name'
}],
listeners: {
itemclick: function(view){
var grid = view.ownerCt,
next = grid.nextSibling();
vp.getLayout().setActiveItem(next);
}
}
}, {
xtype: 'grid',
store: {
fields: ['name'],
data: [{
name: 'Name 3'
}]
},
columns: [{
flex: 1,
dataIndex: 'name',
text: 'Name'
}],
listeners: {
itemclick: function(view){
var grid = view.ownerCt,
next = grid.previousSibling().previousSibling();
vp.getLayout().setActiveItem(next);
}
}
}]
});
});
Obviously that's not MVC style, but that's the structure the layout should take.
