Ext.ux.ColorField

[rpetrello]

Recently I found myself in need of a Color Picker. I checked out what Ext had to offer, and wasn't totally satisfied with Ext.ColorPalette, so I decided to write my own.

My ColorField widget uses <canvas>, so isn't support in some major browsers, but falls back to the Ext.ColorPalette when necessary support is missing.

For those interested, you can find the widget at:

I love this widget, it's beautiful and easy to use.

The only problem I had is that it tries to change the color of the container during the render and in my case, I don't want a default value in the textbox, so I just added a conditional. Here's the page where I'm using it: http://www.freewebs.com/jokurocks/Ex...ss/Themer.html

onRender : function(ct, position){
        Ext.ux.ColorField.superclass.onRender.call(this, ct, position);
        if(this.value)
        this.fireEvent('change', this, this.value);  
    },

Great plugin! I've been using it and the client loves it.

A word to possibly help the next guy out, though: I only store the hex (without the #) in the database. If the hex number is only numeric when re-populating the color field (such as 336699), the app errors in the following line:

116 parseColor : function(value){
117           return (!value || (value.substring(0,1) != '#')) ?
118               false : (value.length==4 || value.length==7 );
119    },

It can't do a substring of what JS thinks is an integer.

I didn't want to change the js to cast value to String, because I like to keep plugins free of my meddling (to make upgrades easier). So, I add a # at the beginning of this data when I pull it back out from the database when populating this field.

Best wishes,
Cat

Hi there, looks really nice for the color wheel plugin! I'm rather new to ext js but i run to some problem when trying to run this great plugin!

When i downloaded it, there are no images in the image folder and when I try to run it I got an error saying this.gradient has no properties. Did I not do something? Thanks for any input!

[mephi]

yes I downloaded the zip to and there is no images on images directory ... can u please check the archive again?

i like the field too!

suggestion: add a listener for onKeypress = "enter" to submit changes typed in directly (connect it to the function "onLosefocus").


kind regards, tobiu
