Drawing Style

The drawingStyle preference in the Preferences dialog provides a simple selection of FBDK or Plain drawing styles. As shown below, the Plain style may be more suitable for producing images for reproduction in black-and-white media, or where the labeling of transition priorities may be unreadable in reduced images.
Fill Colors
In the FBDK style, a fill color is used to indicate that a graphic element is mouse-selectable. In the example below, the I/O declarations of a function block type are mouse-selectable, but the body of the type declaration is not.	In the Plain style, the fill color of all elements is plain white.
Transition Priorities
In the FBDK style, transition priorities are shown in the ECC.	In the Plain style, transition priorities are not shown.
