FileMaker buttons are now very nice and easy to use and format in your layout with text and graphics. The ability to add your own graphical icons to a solution from .png files is a great feature - in addition to already having the useful set of icons FileMaker includes right-out-of-the-box.
The included icons are stored as part of the FileMaker application package (I have a Mac) and exist therein as .svg (scalable vector graphics) files. They have a nice feature in that they "high-light" to a darker shade of gray when a button in a button-bar is "active". Icons you add yourself appear the same when a button is either active or inactive.
Does anyone know how to add additional "built-in" icons for use in formatting buttons/popovers, or to make user-added icons behave graphically similarly to the built-ins?
Thanks for sharing any knowledge you may have.
