No, it may not be true.



The SecurityManager might disallow you the full screen control. Mainly because one could easily fake whole screen in order to grab a password from not-suspecting user (you could mock a bank website).



It can be false:




  • in an applet

  • in a WebStart Application

  • while running in headless mode


JavaDOC of GraphicsDevice.isFullScreenSupported:




Returns true if this GraphicsDevice supports full-screen exclusive
mode. If a SecurityManager is installed, its checkPermission method
will be called with AWTPermission("fullScreenExclusive").
isFullScreenSupported returns true only if that permission is granted

            A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

            Image
            0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{
