OVERVIEW<\/strong><\/p>\n\n\n\n

Toolbars are a band of icons, with or without text which span across the length or breadth of a window. They can contain controls like labels or dropdowns and they can be dockable. Here we look at how to make a single toolbar with icons and handle clicks on the icons. The icons are generated from PNG files. In the sample code, we let wxWidgets size the icons as required, but otherwise you can set the size of the icons also.<\/p>\n\n\n\n

SAMPLE CODE<\/strong><\/p>\n\n\n\n
