Hi guys,

Running revo 2.1.3 advanced.
xamp running.

I am making some CMPs with MODext and I have a requirement to show a preview of an image in an update form.

I am pre-populating the form fields using this.menu.record.
When the user right-clicks the record it launches my window.

What I want is a field or xtype that lets me set a preview if the modx-combo-browser has a value.
I have tried this: but its blank:

{
            fieldLabel: 'Preview'
            ,name: 'image-preview'
            ,dataIndex: 'image-preview'
            ,renderer:
            function(value) {
                return 'Preview img here please...';
                if(value != '')
                {
                    return 'We have an img, show preview';
                } else
                {
                    return '<span class="red">No fail...no img!!!</span>';
                }
            }
        }

Any ideas how I might accomplish this?
Thanks in advance

J

did you try something like that (to add in the property of the field where you want to display your image
(I did not test it )


    html: '<img src="path/to/your/image.png" />',
    height: 150,
    widht: 250

Cheers

Thanks for the reply.
I think what I can do is this, I tried something with other update panels and it seems to work.

Pull out this.menu.record and access the data rowe directly.
I can then inject html straight into a blank div.

I'm sure there is a far easier way to do it, but there is precious little documentation and or tutorials on MODext.
