Windows title icon

How can i set icon (font awesome) on the left side of the header title?

Hello Nikolai_Dimentiev,

To insert a Font Awesome icon into the Window component before the header text, you can use the.add()method with the index0:

dhxWindow.header.data.add({ icon: "..." }, 0);  

This will place the icon at the beginning of the header.

Here’s documentation about .add()method : JavaScript Window - Customization | DHTMLX Suite 9 Docs

Here’s an example: DHTMLX Snippet Tool
