[OPEN-1006] Panel does not expand to defined height when rendered collapsed

In the below example, the panel does not expand to the defined height of 200, but rather the content's defined 50. If the anchor layout is removed from the parent panel, it seems to work fine.

Code:

App = new Ext.Viewport({ layout: "border", items: [ { region: "center", border: false, layout: 'fit', items: [ { border: false, layout: 'anchor', items: [ { anchor: '100%', height: 200, collapsible: true, collapsed: true, title: 'Expand me!', items: [ { height: 50, border: false, html: "Content" } ] } ] } ] } ] })

Bug?

Should this be posted to the bugs forum? I wanted to post here to make sure it wasn't a user error first.

It looks like overnested - remove the unnecessary containers and try again.

This is the simplest example I can come up with. The panel will not expand at all since there are no items in the child, even though it says it should have a body height of 200. If it had a child that had a height of 50, it would only expand to the 50, not the 200 specified.

Code:

new Ext.Panel({ border: false, layout: 'anchor', renderTo: 'main', items: [ { anchor: '100%', height: 200, collapsible: true, collapsed: true, title: 'Expand me!' } ] });

This is obviously an issue being caused by the anchor layout, though I'm assuming anchor layouts and collapsed panels should work together fine.

Yes, it looks like a bug. If collapsed is true, the height is ignored. If collapsed is false, it works as expected. I'm moving this thread to bugs. Complete showcase follows:

HTML Code:

<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <link rel="stylesheet" type="text/css" href="ext-3.2.1/resources/css/ext-all.css"> <script type="text/javascript" src="ext-3.2.1/adapter/ext/ext-base.js"></script> <script type="text/javascript" src="ext-3.2.1/ext-all-debug.js"></script> <title id="page-title">Title</title> <script type="text/javascript"> Ext.BLANK_IMAGE_URL = 'ext-3.2.1/resources/images/default/s.gif'; Ext.onReady(function() { new Ext.Panel({ border: true, width:300, height:500, layout: 'anchor', renderTo: Ext.getBody(), items: [ { anchor: '100%', height: 200, collapsible: true, collapsed: true, title: 'Expand me!', html:'content' } ] }); }); </script> </head> <body> </body> </html>

If anyone could provide a patch for this, I would be eternally grateful. Need to get this working or find another way.

Trying using forceLayout: true.

That doesn't work either.

A very quick and very dirty fix. Tested on FF 3.6, Chrome 9 and IE 8.

PHP Code:

Ext.override(Ext.Panel, { onExpand: function(doAnim, animArg) { var cel = this[this.collapseEl]; if ((cel.getHeight() === 0) || (cel.getWidth() === 0)) { var h = this.height - this.getFrameHeight(), w = this.width - this.getFrameWidth(); if (h) cel.dom.style.height = h + 'px'; if (w) cel.dom.style.width = w + 'px'; (function() { if (w && h) this.body.setSize(w, h); else if (w) this.body.setWidth(w); else if (h) this.body.setHeight(h); this.doLayout(false, true); }).defer(1, this); } if (doAnim) { this[this.collapseEl].slideIn(this.slideAnchor, Ext.apply(this.createEffect(animArg||true, this.afterExpand, this), this.expandDefaults)); } else { this[this.collapseEl].show(this.hideMode); this.afterExpand(false); } } });
