How do I center my windows on screen?

SuperCard 3.0 provides a window property called "autoCenter" - when set to true the window is automatically drawn at the center of the main monitor when it is opened. For earlier versions of SuperCard there are a number of ways to do this, but one of the fastest and cleanest ways is to simply center it before opening it, using SuperTalk's "screenLoc" function: -- Sample "About" script -- This script will set the loc of a window name "About" -- match the center of the current monitor, and then open it. -- Remember that a window's location is always given in -- global coordinates. -- on DoAbout set the loc of window "About" to screenLoc() show wd "About" end DoAbout
