If you wish to keep the window from closing, return the value false. Note that if you always return false, HC will be unable to quit. If the MegaCloseRequest handler does not exist, or it contains a scripting error, MegaWindow will display a dialog box asking whether you wish to close the window and act accordingly. Return to Top of Page Window Properties MegaWindows have properties you can Get and Set like any other HyperCard object. Return to Top of Page A complete list of properties follows.
Title is the title of the window.
This is always set when you create the window. Name can also be substituted. Rect is the window's rectangle, in coordinates local to the card. All other built-in rectangle properties, like height, width, loc, top, bottom, etc. work too. If you follow the rect with a C, the window will be centered on the main screen.
