ExtJs Grid heights and scroll bars eurgh - extjs4

Question

I have a quite a complicated layout for my application, using borders, vbox's and hbox's which all seem to fit quite well except for one annoyance. The bottom of the grid in the southern region is not behaving. I want the grid to take up the height of the panel when the browser is above minHeight/maximized but at the moment it look like this:
And when the browser is shrunk (but not below min size) it looks like this and I am unable to get to the bottom of the grid scrollbar :(
You can see the scrollbar cut of (probable min height on the viewport/grid issue) but not sure how to fix this can someone spot what I need to do resolve these two issues? Code below:
<script type="text/javascript" src="../app.js"></script>
<!-- script to warn users when leaving page -->
<?php
$db = Zend_Registry::get('db');
$result = $db->query("select ERROR_ID, ERROR_DESCRIPTION, EMAIL_CONTENT, to_char(\"TIMESTAMP\", 'MM/DD/YYYY HH24:MI:SS') as TIMESTAMP, READ from PI_EMAIL_ERROR where \"TIMESTAMP\" = ( select max(\"TIMESTAMP\") from PI_EMAIL_ERROR ) and READ = 0 and rownum = 1")->FetchAll();
?>
<script type="text/javascript">

Answer 1

I'm referring to lines 87-97 of the syntax highlighted link you posted.
resize: function(){
var programGrid = Ext.getCmp('programList');
if(this.getHeight() < this.minHeight){
console.log("Height: ", this.getHeight());
console.log("minHeight: ", this.minHeight);
console.log("Grid old height: ", programGrid.height);
programGrid.height = (this.minHeight - programGrid.height)-18;
this.setSize(this.getWidth(), this.getHeight());
console.log("Grid new height: ", programGrid.height);
} else {
programGrid.height = 380;
}
}
This is the resize handler for the viewport, so every time the browser is resized, this funciton will explicitly set the grid height. Not sure what the purpose of this code is but it looks like it could be the issue. Generally you shouldn't need code like this - everything should fit together if you have the layouts set up right, and then you can use minHeight/maxHeight for the grid if you want. What happens if you just take this code out?

Answer 2

I think you need to remove the resize event handler completely. It looks like you're trying to create a 'vbox' layout on your center panel, but you're using 'type: vbox'. Try using this:
layout: {
type: 'vbox'
align : 'stretch',
pack : 'start',
}
This was taken from the ExtJS examples (http://docs.sencha.com/ext-js/4-2/extjs-build/examples/layout-browser/layout-browser.html). Then you can just add a 'flex' to your child containers instead of a minheight.
