Creating a custom theme for a tree panel in Ext JS 4

I'm looking to start customizing a Sencha 4 Tree panel, adjusting elements like text size and background colors. So far, I haven't been able to figure out the right approach, whether it's through viewConfig or some other method. Here's the code I currently have:

JS:

var store = Ext.create('Ext.data.TreeStore', {
    root: {
        expanded: true,
        children: [
            { text: "detention", leaf: true },
            { text: "homework", expanded: true, children: [
                { text: "book report", leaf: true },
                { text: "algebra", leaf: true}
            ] },
            { text: "buy lottery tickets", leaf: true }
        ]
    }
});

Ext.create('Ext.tree.Panel', {
    title: 'Simple Tree',
    width: 400,
    height: 250,
    store: store,
    rootVisible: false,
    renderTo: 'nav'
});

HTML:

<div id='nav'>

</div>

CSS:

#nav .x-tree-node-text  {
    font-size: 1.3em;
    background-color: #c0c0c0;
}

Is there a better method to achieve this customization? I appreciate any guidance!

Answer №1

If you're looking to customize the appearance of different text objects within a theme, you can utilize a similar technique. For example, to adjust the text color of nodes, you can apply the following CSS:

#nav .x-grid-cell-inner{
    color: #ff0000;
}

If you want to make a global change throughout your application, avoid using specific #tags (to alter the entire extjs theme).

For further customization:

#nav .x-grid-cell-inner{
    color: #ff0000;
    text-decoration : line-through;
    font-size:larger;
}

Hopefully, this tip proves useful! ;)
