FormPanel to render dynamic forms into LayoutRegions

[aconran]

Small snippet of code to render a dynamic form directly to a LayoutRegion.

var FormPanel = function(formObject) {
FormPanel.superclass.constructor.call(this, Ext.id(), {autoCreate: true});
formObject.render(this.getId());
};
Ext.extend(FormPanel, Ext.ContentPanel);

After creating a dynamic form (named myForm) you can now do this:

layout.add('west', new FormPanel(myForm))

Cannot place a title on this FormPanel ?

Should be able to pass a 2nd parameter into the constructor named config then pass it up to the superclass/ContentPanel. Here is an untested fix, let me know your results:


var FormPanel = function(formObject, config) {
var config = config || {};
FormPanel.superclass.constructor.call(this, Ext.id(), Ext.apply({autoCreate: true}, config));
formObject.render(this.getId());
};
Ext.extend(FormPanel, Ext.ContentPanel);

The var config = config || {}; is giving a syntax error.

I'm using this code now and is working fine....

strange. Gave the syntax error in firefox and IE. I changed it to "var config = config;" and it works fine. Tab title is set correctly as well.

[aconran]

var config = config || {};

Just says if config was passed in as an argument set it to a variabled named config, otherwise set it to a blank object literal.


It could also be done like this:


if (config)
var config = config;
else
var config = {};

How would I go about adjusting the way the form looks in the panel? Any way to inject the html div it would have been applied to if rendered normally?

You would probably want to change

var config = config || {}; to
config = config || {}; since the the config variable is already declared as a parameter. There should be no problem with this, as I use it throughout my apps. I've seen similar stuff in the Ext code too.

Well, I actually went back to this after not worrying about it for a long time and I guess my Ext skills must have gotten better because I figured it out pretty quickly. To set the style on the FormPanel container get the element and use setStyle. Here's mine for setting the margins for the example above:


Ext.get(panel.el.dom.parentNode.id).setStyle('margin', '10px 0px 0px 10px');
