Hi,
I have created a custom application and have created new functionalities/menus. I want to add new icons which when clicked will perform actions which are in those menus. For example I have created a build menu which when clicked sets up everything for my simulation. I want to add an icon for the Build process which will do the same thing.
Similar to what open file icon does here. How can I do that?
