GenTrigger: 4 Customizations

GEOS SDK TechDocs

3 Supplemental GenTrigger Usage

You may customize a GenTrigger using all the basic GenClass attributes as shown in the GenClass chapter. Of special significance are the ways in which you can tailor a moniker to print a graphics string on a button, as in a DOS room icon. The moniker should have as its argument a GString. (See the Graphics Environment chapter).
