OVERVIEW: Zoom-Daemon is a program that attaches a ZOOM GADGET to each Intuition window which causes the window to expand to the full size of the screen or contract to the window's minimum size when it is pressed. Pressing the gadget a second time restores the window to its original size. HOW TO USE ZOOM-DAEMON: You should place Zoom-Daemon in your C: directory (or in your current path), and Zoom-Handler in the L: directory (or in the current directory). To start Zoom-Daemon, simply type Zoom-Daemon at the CLI prompt: 1> Zoom-Daemon You do not need to RUN Zoom-Daemon, since Zoom-Daemon loads the handler code separately, sets up the handler, and then exits. To remove the daemon, simply issue the Zoom-Daemon command a second time. Once the Zoom-Daemon is running, new windows that are opened may include a Zoom Gadget which should appear to the left of the depth gadgets in the upper right-hand corner of the window. The Zoom Gadget has a large dark square with a smaller light-colored square inside it (if youy are using the standard workbench colors). If you press this gadget, the window will grow in size to fill the entire screen. Pressing the gadget a second time causes the window to return to its original size. If you press and hold the Zoom Gadget and click the right mouse button while the zoom gadget is still active (a process called "left-right clicking"), then the window will be reduced to its smallest allowable size. Left-right clicking the Zoom Gadget a second time restores the window to its original size. USAGE NOTES: Zoom-Daemon only adds a Zoom Gadget to a window when it meets one of two conditions: 1) it has a SIZING gadget, or 2) it has the NEWSIZE flag set in its IDCMPFlags field. (See "Intuition: The Amiga User Interface" for a description of the IDCMP flags, and the window fields discussed below). Windows with neither of these features probably do not know how to handle window size changes (or could not take advantage of a larger window anyway), so no Zoom Gadget is added to them for this reason. Zoom-Daemon will not increase the size of a window past its MaxWidth or MaxHeight values, even if they are smaller than the size of the screen Zoom-Daemon assumes that the application knew what it wanted when it set the maximum size. Some older programs may have the maximum size set to the standard size of the Workbench screen (640x200) and if you use overscan mode, these windows will not zoom out to the full size of the screen. Zoom-Daemon will not decrease the size of a window past its MinWidth and MinHeight values, nor to a size that would place the Zoom Gadget outside the visible portion of the window. This is an attempt to guarantee that the zoom gadget is always available to resize the window. Pressing the Zoom Gadget (without pressing the right mouse button) zooms the window to its full size even if the window is currently shrunken. Similarly, left-right clicking the Zoom gadget shrinks the window to its minimum size even if the window is zoomed. Thus it is possible to get to any of the three possible sizes (minimum, normal, maximum) from any other size: from minimum size left-right clicking gets to normal size, while clicking gets to maximum; from normal size, left-right clicking gets to minimum size while clicking gets to maximum; and from maximum left-right clicking gets to minimum size while clicking gets to normal size. If you remove the Zoom-Daemon while windows containing a Zoom Gadget are still open, Zoom-Daemon will remove the Zoom Gadgets automatically. You can make Zoom-Daemon part of your standard working environment by adding the "ZOOM-DAEMON" command (or "ZOOM-DAEMON > NIL:") to the startup-sequence file in the S: directory on your boot disk. COMPILING ZOOM-DAEMON: Zoom-Daemon was developed using the Lattice C compiler v4.0 on a 512K Amiga 1000. It probably will need to be modified to work with the Manx Aztec C compiler. To compile and link Zoom-Daemon, use the following commands (these appear in Zoom-Daemon.com, distributed with the source code): 1> lc -b0 -v -M Zoom-Main Zoom-Handler Zoom-Setup 1> lc -b0 -ad -M Zoom-Image 1> asm Zoom-Stubs 1> blink with Zoom-Daemon.lnk 1> blink with Zoom-Handler.lnk The -v -b0 and -ad options are required. You can add -r if you like. The -M is to compile only those source files that have been updated since the last compile. AUTHOR: Zoom-Daemon and Zoom-Handler Copyright (c) 1989 by Davide P.
