The Toolbar Editor allows you to easily create and manage application toolbars. You can add toolbar buttons and controls, create and edit toolbar button images for various color modes and screen resolutions, and associate buttons with command IDs.
The editor supports images in .bmp, .ico, and .png formats with up to 32 bpp colors; therefore, you can quickly adapt the default toolbar (16 colors) to a high-quality, semi-transparent look. In addition, you can use SVG vector images, so your application will be fully DPI-aware.
