SplashAbout

Every application should have a Splash screen and an About dialog. This component makes it as easy as dropping it onto your main form and calling a couple of methods. If you set VersionInfo in your Project Options, then most properties are automatically picked up. Two methods: SplashAbout1.ShowSplash (in form1.create method) and SplashAbout1.ShowAbout. No bloat: Windows are created on-the-fly and destroyed on close. OptionalIcon can be multi-resolution Set OptionalIconSize and the best available resolution/size will be displayed in Splash and About dialogs. Debug Logging available. Compile the /demo project to see what it can do Debug Logging (set DebugMode = TRUE) Windows and Linux.
