How to make Extjs Button look a link? - extjs

Question

I want to either make a link in Extjs or make a button look like a link and on hover you see the button. They do this in the docs with Code Editor button and the Live Preview button.
If they do this using CSS, what CSS do I use and when/how to I apply it?

Answer 1

I recently wanted a LinkButton component. I tried to find a pre-existing component without any luck, so I ended up writing one from scratch. Its implementation is almost entirely CSS-based.
/******************************************************************************/
/*** LINK BUTTON CSS **********************************************************/
/******************************************************************************/
a.ux-linkbutton {
background-image: none;
border: 0px none;
margin-top: 1px;
}
a.ux-linkbutton.x-btn-default-small-focus {
background-color: inherit;
}
a.ux-linkbutton * {
font-size: inherit !important;
}
a.ux-linkbutton:hover {
text-decoration: underline;
background-color: inherit;
}
/******************************************************************************/
/*** LINK BUTTON JS ***********************************************************/
/******************************************************************************/
Ext.define( "Ext.ux.button.LinkButton", {
extend: "Ext.button.Button",
alias: "widget.linkbutton",
cls: "ux-linkbutton",
initComponent: function() {
this.callParent();
this.on( "click", this.uxClick, this, { priority: 999 } );
},
// This function is going to be used to customize
// the behaviour of the button and click event especially as it relates to
// its behaviour as a link and as a button and how these aspects of its
// functionality can potentially conflict.
uxClick: function() {
//Ext.EventObject.preventDefault();
//Ext.EventObject.stopEvent();
//Ext.EventObject.stopPropagation();
//return false;
}
} );
The click handler is a work-in-progress.
The class does have one minor issue: a pseudo-class style is applied after clicking/focusing that I have not been able to remove. If someone fixes it before I do, please, post the CSS for it.

With Ext 4.0.7 I had managed to do the following:
View:
...
{
xtype: 'button'
,text: 'Discard changes'
,action: 'cancel'
,cls: 'secondary-action-btn'
}
CSS:
....
.secondary-action-btn {
border: none;
background: none;
}
.secondary-action-btn span {
cursor: pointer;
text-decoration: underline;
}

I recall there is an extension called linkButton. You can refer to the extjs forum here
