OVERVIEW ---------------------------------------------------------------------------- GadgetED is designed to save the Amiga programmer a lot of time in creating intuition gadgets. This version of GadgetED has the following features: o - editing gadgets for a workbench or a custom screen. o - editing gadgets for a window or a requester. o - full control over the window flags. o - adding, modifying, moving and deleting texts for gadgets and window. o - adding, editing, moving, re-sizing, deleting and copying of gadgets. o - loading IFF-ILBM brushes as gadget rendering. o - loading IFF-ILBM colormaps for custom screens. o - a palette editor to create your own custom colors. o - title line gadget information. o - fully mouse and keyboard controlled. o - generation of source code in C or Assembler. o - binary saving for later loading and editing. ---------------------------------------------------------------------------- II. REQUIREMENTS ---------------------------------------------------------------------------- GadgetED was programmed in Aztec C V5.0a on an Amiga 500 Kick 1.3 with 2 Meg memory and a 20Meg HardDisk but it should run on a standard 512 K machine. What you do need to work with GadgetED is a C Compiler and/or an Assembler with all the standard include files. GadgetED also requires a copy of the "tool.library", which is also on this disk, to be copied into the LIBS: directory of the GadgetED boot disk. ---------------------------------------------------------------------------- III. STARTING GADGETED ---------------------------------------------------------------------------- GadgetED can be run from the CLI or the workbench. If you run GadgetED from the workbench all you have to do is double-click the "GadgetED" icon or one of the "GE" icons. If you want to run GadgetED from the CLI just type "GadgetED [filename]" where "filename" is an optional name of the "GE" file you want to edit. When you have started GadgetED without a filename a little window opens in the middle of the screen with the following gadgets: WINDOW - selecting this gadget tell's GadgetED that you want to edit gadgets for a window. REQUESTER - selecting this gadget tell's GadgetED that you want to edit gadgets for a requester. 1 - custom screen, depth = 1, 2 colors. 2 - custom screen, depth = 2, 4 colors. 3 - custom screen, depth = 3, 8 colors. 4 - custom screen, depth = 4, 16 colors. (SLOWS UP THE 68000) 5 - custom screen, depth = 5, 32 colors. WORKBENCH - if you select this gadget GadgetED still opens it's own screen but the colors are the same as your workbench and the generated structures will be for the workbench screen. When you are done click "OK" and a screen opens with a little window on it. If you click on "CANCEL" you leave the program again. NOTE: If you have selected to edit gadgets for a requester you will see a window with a colored rectangle in it. This rectangle represents the requester you are working on. You can size and position the window in order to get the requester how and where you want it. Now let's create our first gadget. Move the mouse pointer to where you want the top-left corner of the gadget to be and click the left mouse button. If you look at the screen title now you will see some information displayed. This information means, from left to right: o - the mouse pointer X coordinate. o - the mouse pointer Y coordinate. o - the gadget left edge. o - the gadget top edge. o - the gadget width. o - the gadget height. NOTE: The values are relative to the top-left corner of the window/requester This information is important to place and size your gadget exactly the way it should be. If you move the mouse pointer the values in the info-line will change and a box will follow the mouse pointer relative to the top-left corner. This box represents the gadget. When the box is the way you want the gadget to be you must click the left mouse button again and the gadget will be added to the window or requester. Now you have created your first gadget with GadgetED so let's take a look at the menus to see what else you can do. ---------------------------------------------------------------------------- IV. THE PROJECT MENU ---------------------------------------------------------------------------- This menu consists of the following items: About: <right Amiga ?> Function: display information about the copyright, the author and the language GadgetED was programmed in. Just click on the CONTINUE gadget to get rid of it. New: <right Amiga N> Function: erases all gadgets and changes made sofar and resets the display to the default. If the changes made where not saved a requester opens telling you this and asking you if you really want to do this. Click on the NO gadget if you made a mistake by calling this function otherwise click on the YES gadget. NOTE: If you proceed with this function and the changes where not saved there is no way to get back the information. Load: <right Amiga L> Function: This opens the file requester. In this file requester you can type or select the name of the 'GE' file you want to load. NOTE: The program only loads 'GE' files. If you try to load a file that is not a 'GE' file a requester appears telling you that the file you have selected was of an Unknown type. When the file you have selected is successfully loaded. The screen displays now displays the gadgets e.c.t. found in the file. Save: <right Amiga S> Function: This opens the file requester in which you can type or select a name under which the current display is saved. You should always save the display before you exit the program. This ensures the file is always up to date. If you do not save the display before quiting the program any changes made since the last time you saved will be lost. Generate Source: C: <right Amiga C> Function: This generates the source code in C of the display edited sofar. In the file requester you can type or select the name under which the generated source code is saved. Assembler: <right Amiga A> Function: As with C only the generated source code is in MC68000 Assembler. Preferences: <right Amiga P> Function: This is used to (un)set certan preferred program flags. It opens a window with the following gadgets: Skip zero bit-planes : This tell's GadgetED to skip any image bit- planes that only contains zero's. This will reduce the size of the image data source GadgetED generates. Auto Gadget -> Image size: This tell's GadgetED to automaticly adjust the dimensions of the gadget to the dimensions of the loaded image. Image Copy : This tell's GadgetED to also copy any images that might be attached to a gadget. WINDOW or REQUESTER : Switch from editing gadgets for a window to editing gadgets for a requester or viceversa. Save : Save the preferences to a file called 'DEVS:GadgetED.PREFS'. Use : Set the preferences in the program. Save & Use : Both save and set these preferences. Close WorkBench or Open WorkBench: Function: This enables you to close/open the workbench screen. You can close the workbench screen if your (!!computer!!) memory is running a little low. NOTE: It's only possible to close the workbench screen if there are no programs running that use the workbench screen. This means that if you started GadgetED from the CLI it isn't possible to close the workbench screen because the CLI is a program that makes use of the workbench screen. Quit: <right Amiga Q> Function: Quits GadgetED if you select YES in the requester that opened to ask you to if you really want to do this. ---------------------------------------------------------------------------- V. THE GADGETS MENU ---------------------------------------------------------------------------- In this menu a lot of functions are defined which asks you to pick a gadget to perform a certain action.

When you are editing gadgets for a requester: Set BackFill: <right Amiga B> Function: This enables you to set the backfill color of the requester. The color used is set by the BPen menu (see THE FPEN & BPEN MENUS) ---------------------------------------------------------------------------- VI. THE FPEN AND BPEN MENUS ---------------------------------------------------------------------------- When one of these two menus are selected you will see a row of 2,4,8,16 or 32 (depending on the screen depth) colored items. These items represent the colors of the edit screen. With the items in the FPen menu you can set the active FrontPen color. All gadgets added will have a border in this color and all texts added will have this color as the FrontPen color. With the items in the BPen menu you can set the active BackPen color. All texts added will have this color as the BackPen color. The active BackPen color is also used to set the BackFill color of the requester. ---------------------------------------------------------------------------- VII. THE GENERATED SOURCE CODE ---------------------------------------------------------------------------- The following defenitions are made at the end of the generated source: NEWWINDOW or REQUESTER - a pointer to the NewWindow or Requester structure. FIRSTGADGET - a pointer to the first gadget in the list. If there where texts added to the window or requester: FIRSTTEXT - a pointer to the first text in the list. If there where 'BORDERONLY' gadgets defined: FIRSTBORDER - a pointer to the first border in the list. If you have edited gadgets for on a custom screen: NEWSCREEN - a pointer to the NewScreen structure. COLORCOUNT - the number of colors in the screen. An array named 'Colors' of USHORT values containing the colors which where on the edit screen. These colors can be set by a simple LoadRGB4() call. If you have edited gadgets for a window and you have attached texts and/or 'BORDERONLY' gadgets to the window a special gadget is placed at the end of the gadgetlist. This gadget is only there to draw the borders and the texts when the window is opened or when the gadgets are refreshed. The GadgetID's are defined as following: Label_ID This means that if you, for example, added a gadget with the label "UP" than "UP_ID" will represents this gadget it's ID. The best way to see what the source looks like is to create some gadgets and let GadgetED generate the source and then look at it. Bassicly all you need to remember are the labels you give your gadgets to be able to acces all of the structures etc. that are linked to these gadgets. I don't really know if the generated C source compiles under lattice , I don't have lattice, but it should give no problems whatsoever. ---------------------------------------------------------------------------- VIII. COMPILING ---------------------------------------------------------------------------- If you have the make utility type: make pre ged Otherwise copile the "defs.h" file with the "-ho defs.pre" option and all other files with the "-so -hi defs.pre" options and then link them together. ---------------------------------------------------------------------------- IX. HISTORY ---------------------------------------------------------------------------- VERSION 1.0 -> Let's not talk about this! VERSION 2.0 -> First release, let's see how it goes. ---------------------------------------------------------------------------- X. NOTES ---------------------------------------------------------------------------- If you take a good look at the supplied source code I'm sure you are ready to throw up but this is what source looks like after a mere 30.000.000.000 changes! My advice to you is too think real hard about what a program must be able to do !!!!BEFORE!!!! you start to code it. Although this is version 2.0 af GadgetED it is the first release. I wish to add Modula and/or OBERON support in the future if only I knew how to declare all of the stuctures etc. in these languages. If you find bugs, I bet you will, or you have ideas to make the program more user-friendly, please report to me at the following adress: Jan van den Baard Bakkerstraat 176 3082 HE, Rotterdam Holland.
