The Web Viewer is at the core of all BlackBoxes. When deciding how to build a BlackBox component, you will need to know a few important things about how the Web Viewer works.
Web Viewer Basics
For starters, the Web Viewer uses your web browser to render the page. If you are using Windows, it will ALWAYS use your installed version of Internet Explorer to render the page. If you are using a Mac, the Web Viewer will ALWAYS use your installed version of Safari - It doesn't matter what your 'Default' web browser application is, FileMaker will always use either Internet Explorer or Safari.
When building a BlackBox, you need to remember to test on both Internet Explorer and Safari, but not only that, you need to think about testing on the different versions of these browsers, as they can all behave differently.
Internet Explorer
Internet Explorer requires special consideration, especially if you are planning on supporting the different browser versions. Each version of Internet Explorer renders some content quite differently - If the user has IE 8 installed however, be aware that the web viewer will never use IE 8 Standards mode, unless forced to - find out here.
Web Viewer Options
In the lower part of the Web Viewer Setup dialogue, you are given several checkbox options which affect how the Web Viewer displays and behaves on your layout.
