An area I particularly wish to investigate is whether Region edit mode could be integrated better within HyperCard ΓÇô for example marching ant selection as for buttons and fields. Encourage me with postcards if you want to see another version.ΓÇó Will there be further releases of Regions?┬á┬á┬á┬áI plan to look at Regions again in a few months. An area I particularly wish to investigate is whether Region edit mode could be integrated better within HyperCard ΓÇô for example marching ant selection as for buttons and fields. Encourage me with postcards if you want to see another version.ΓÇó Why not drag or grow on click?┬á┬á┬á┬áWhen clicking on buttons/fields you can drag or grow according to where you click. I tried this with regions, but delimiting the two areas (drag & click) was not easy/obvious so I switched to the two modes now present.ΓÇó What does install_BMTR do?┬á┬á┬á┬áIf you ask this it means you've been poking around ΓÇô good for you! It is used to add a trap which is required by the Picture Window WDEF but is currently only present in 32bit QuickDraw systems. For further details see the stack <a href="#" class="group">┬╖┬áPicture┬áWDEF┬áΓÇÜ</a>.ΓÇó Can I use the WDEF & MDEF in my code?┬á┬á┬á┬áYou can use the WDEF and/or MDEF in your own code on the same basis as Region ΓÇô ┬⌐ Nigel Perry, no commercial/profit-making/ ShareWare use without permission, otherwise free. See the <a href="#" class="group">┬╖┬áPicture┬áWDEF┬áΓÇÜ</a> & <a href="#" class="group">┬╖┬áPicture┬áMDEF┬áΓÇÜ</a> stacks for more details.ΓÇó I wish Region didΓÇª┬á┬á┬á┬áHavn't covered your question? Email me.ΓÇó Why did I get a SysError with Owl?┬á┬á┬á┬áWhen trying to draw the Owl picture on my 1Mb Plus a fatal SysError occurs when the memory is exhausted somewhere inside QuickDraw. There seems to be no easy way to predict when this might happen and hence avoid it. Sorry.ΓÇó How did you get those ΓÇ£stickyΓÇ¥ buttons?┬á┬á┬á┬áSee the stack <a href="#" class="group">┬╖┬áSticky┬áButtons┬áΓÇÜ</a> and all will be revealed.ΓÇó Whats your real job?┬á┬á┬á┬áI am a full time researcher in Computer Science, currently working on the design of concurrent functional object/process-oriented languages.

Region will also use a simple dialog when editing handler scripts instead of the standard Script Editor ΓÇô which takes up 80k! Setting memLow will slow you down, only use it when you are really tight on memory (like lots of regions and only 1MbΓÇª).</text> </content> <name></name> <script></script> </card> card_5244.xml <?xml version="1.0" encoding="utf-8" ?> <!DOCTYPE card PUBLIC "-//Apple, Inc.//DTD card V 2.0//EN" "" > <card> <id>5244</id> <filler1>0</filler1> <cantDelete> <false /> </cantDelete> <showPict> <true /> </showPict> <dontSearch> <false /> </dontSearch> <owner>2599</owner> <link rel="stylesheet" type="text/css" href="stylesheet_3093.css" /> <content> <layer>background</layer> <id>4</id> <text>dding Pictures to a StackWhen there is a picture (PICT) on the clipboard the Edit menu contains a Paste Picture item.

Regions can also have event handlers, however unlike other HyperCard objects you cannot edit these with the script editor but instead you must use the set & get as for properties, or the Regions menu. The following is a list of region properties:locrectvisibleautoHilitehilite┬á┬á┬á┬áThese properties are the same as the standard HyperCard button & field properties. The coordinates for the loc & rect properties are relative to the current card. The visible property can also be changed by the HyperTalk commands; show/hide window and show/hide palettes.mouseWithinmouseDownmouseStillDownmouseUpidle┬á┬á┬á┬áThese properties may be set to any HyperCard command(s). The commands may optionally be enclosed by the standard HyperTalk on <message> & end <message> statements. The HyperCard commands are executed when the appropriate event occurs, just like standard HyperTalk handlers. The idle handler will not be called unless the idleTime property has been set (see below). The mouse-related handlers are not executed when in region edit mode. When the commands are executed the standard HyperTalk property the target is set to the current card and the global variable targetRegion is set to the name of the region.idleTime┬á┬á┬á┬áThis property is the desired number of ticks (1/60 sec) between invocations of the regions idle handler. A value of 0 prevents the idle handler being called and is the default value.</text> </content> <name>Properties</name> <script></script> </card> card_2446.xml <?xml version="1.0" encoding="utf-8" ?> <!DOCTYPE card PUBLIC "-//Apple, Inc.//DTD card V 2.0//EN" "" > <card> <id>2446</id> <filler1>0</filler1> <cantDelete> <false /> </cantDelete> <showPict> <true /> </showPict> <dontSearch> <false /> </dontSearch> <owner>2599</owner> <link rel="stylesheet" type="text/css" href="stylesheet_3093.css" /> <content> <layer>background</layer> <id>4</id> <text>he Regions MenuThe menu is available whenever you are in edit mode and determines what effect a mouse click over a region has. The current region edit mode along with the current major mode entries in the menu are hilited. The menu is a palette and may be ΓÇ£torn offΓÇ¥ and placed anywhere on the screen (option+Tab will toggle its visibility just as it does for the Tools palette). Region edit mode was entered automatically when this card was opened and will be left when you go to the next card. The menu entries are:A┬á┬á┬á┬áClick-dragging on a region will drag it around, just like a window. Γîÿ-click-dragging will drag without bringing it to the front. When edit mode is entered Drag is selected.B┬á┬á┬á┬áClick-dragging on a region will resize it, as regions are windows you may only grow/shrink to the right/bottom.C┬á┬á┬á┬áClicking on a region will bring it to the front of all the regions & HyperCard palettes.D┬á┬á┬á┬áClicking on a region will send it behind all other regions and HyperCard palettes, but keep it in front of the card window.E┬á┬á┬á┬áClicking on a region will resize it to its normal size, i.e. the bounding rectangle of the picture it is displaying.F┬á┬á┬á┬áCreate a new region.

When in region edit mode a new menu Regions is added to the menu bar and you may move, resize, change the front-to-back layering etc. of your regions. When in edit mode the cursor will change to the standard arrow or a special cursor when over a region.Entering Edit ModeEdit mode is automatically entered whenever you use the New RegionΓÇª menu item to create a new region. It may also be entered by selecting RegionΓÇª from the Edit menu or by holding down the option key while selecting one of the browse, button or field tools from the Tools menu.Leaving Edit ModeEdit mode may be left by choosing any tool from the Tools menu; by selecting the browse, button or fields tools from the Regions menu; or by typing Γîÿ+Tab to return to browse mode.</text> </content> <name></name> <script></script> </card> card_3660.xml <?xml version="1.0" encoding="utf-8" ?> <!DOCTYPE card PUBLIC "-//Apple, Inc.//DTD card V 2.0//EN" "" > <card> <id>3660</id> <filler1>0</filler1> <cantDelete> <false /> </cantDelete> <showPict> <true /> </showPict> <dontSearch> <false /> </dontSearch> <owner>2599</owner> <link rel="stylesheet" type="text/css" href="stylesheet_3093.css" /> <content> <layer>background</layer> <id>4</id> <text>reating RegionsThere are two ways to create a region: using HyperTalk, either in a script or the message box; and using the Objects menu.Creating Using HyperTalkTo create region use the command:Region name, loc, picture1, ┬á┬á┬á┬á┬á┬á┬á┬á┬á┬á┬á┬á┬á┬á┬á┬á┬á┬á┬á┬á┬á[Lasso|Masked|picture2]This will create a new region using picture1, Lassoed, Masked or picture masked with picture2. If loc is a point then the top-left corner of the region will be placed there, these coordinates are relative to the top-left corner of the current card. If loc is a rectangle then the region is sized to fit. For example <a href="#" class="group">Region Insect, "300,-20", Butterfly, Lasso</a> will place a region just to the right and slightly above this card window (click to try it). The name is used for the title of the regions window and may be used in HyperTalk window related commands, for example <a href="#" class="group">set the loc of window Insect to "300,150"</a> (click only if you created an Insect, otherwise you'll get a HyperTalk error).Creating Using The MenusWhenever you are regions there is a new entry New RegionΓÇª in the Objects menu. (If the entry is not there you can add it with the HyperTalk command <a href="#" class="group">setupRegions</a>, this may happen if your userLevel was too low when Regions was initialised.) Selecting this menu item will present you with a dialog in which you may specify the region name and select the picture(s) from PopUp menus of those. On pressing Ok the new region will be created and positioned at (0,0) and you will be left in drag mode, you may drag the region to where you wish and then type Γîÿ+Tab, or select the hand tool from the Tools menu, to return to browse mode. The HyperTalk commands <a href="#" class="group">doMenu "New RegionΓÇª"</a> and <a href="#" class="group">Region New</a> are equivalent to selecting from the menu.</text> </content> <name></name> <script>on openCardshow groupspass openCardend openCardon closeCardhide groupspass closeCardend closeCard</script> </card> card_3873.xml <?xml version="1.0" encoding="utf-8" ?> <!DOCTYPE card PUBLIC "-//Apple, Inc.//DTD card V 2.0//EN" "" > <card> <id>3873</id> <filler1>0</filler1> <cantDelete> <false /> </cantDelete> <showPict> <true /> </showPict> <dontSearch> <false /> </dontSearch> <owner>2599</owner> <link rel="stylesheet" type="text/css" href="stylesheet_3093.css" /> <content> <layer>background</layer> <id>4</id> <text>ow a Region is ConstructedA region is constructed from one or two named pictures (ΓÇ£PICTΓÇ¥ resources), these pictures must be in: the current stack, a stack being ΓÇ£usedΓÇ¥, the Home stack, HyperCard or the current System. There are three variations of regions; lassoed, masked and picture masked. All regions display a picture in a ΓÇ£windowΓÇ¥, the difference between the variations is in how the region area is determined.Lassoed RegionFor a lassoed region the area is formed by lassoing the picture to be displayed within the region, as with with the HyperCard lasso tool. A lassoed region will not contain any holes, but may consist of multiple non-contiguous areas. For an example press: <a href="#" class="group">┬╖┬áLasso┬áΓÇÜ</a>.Masked RegionThe area of a masked region is formed from the black pixels of the picture it is to display. It may contain holes and non-contiguous areas but will not contain any white pixels ΓÇô as those in the picture will fall outside the region area. For an example press: <a href="#" class="group">┬╖┬áMasked┬áΓÇÜ</a>.Picture Masked RegionA picture masked region is constructed from two pictures. The first is displayed within the region and the black pixels of the second are used to define the region area. This comb-ination allows you to construct a region which is selectively transparent and/or contains areas which are white.For an example press: <a href="#" class="group">┬╖┬áPicture┬áMasked┬áΓÇÜ</a>.Variation DemonstrationIf you press the button: <a href="#" class="group">┬╖┬áVariation┬áDemo┬áΓÇÜ</a>, you will get three draggable regions, one of each variation (ignore the new menu that appears for the moment). Note that the cursor changes to an arrow when over a draggable region, instead of the usual HyperCard hand. Move them around by clicking and dragging in the usual way. If you Γîÿ-click-drag the regions will keep their front-to-back ordering, otherwise a dragged region will automatically come to the front ΓÇô just as with normal windows. When you are done press: <a href="#" class="group">┬╖┬áEnd┬áDrag┬áMode┬áΓÇÜ</a>.</text> </content> <name></name> <script>on __Lasso__global openWindows1cleanupWindows openWindows1Region NormalRegion Board,"315,0","%Lasso Variation",LassoRegion Demo,"360,180","%Variations Picture",Lassoend __Lasso__on __Masked__global openWindows1cleanupWindows openWindows1Region NormalRegion Board,"315,0","%Masked Variation",LassoRegion Demo,"360,180","%Variations Picture",Maskedend __Masked__on __Picture_Masked__global openWindows1cleanupWindows openWindows1Region NormalRegion Board,"291,0","%Picture Variation",LassoRegion Demo,"360,180","%Variations Picture","%Variations mask"end __Picture_Masked__on __Variation_Demo__global openWindows1cleanupWindows openWindows1Region Demo,"360,0","%Variations Picture",LassoRegion Demo,"360,90","%Variations Picture",MaskedRegion Demo,"360,180","%Variations Picture","%Variations mask"Region Editend __Variation_Demo__on __End_Drag_Mode__Region Normalend __End_Drag_Mode__on closeCardRegion Normalpass closeCardend closeCard</script> </card> card_5110.xml <?xml version="1.0" encoding="utf-8" ?> <!DOCTYPE card PUBLIC "-//Apple, Inc.//DTD card V 2.0//EN" "" > <card> <id>5110</id> <filler1>0</filler1> <cantDelete> <false /> </cantDelete> <showPict> <true /> </showPict> <dontSearch> <false /> </dontSearch> <owner>4843</owner> <link rel="stylesheet" type="text/css" href="stylesheet_3093.css" /> <content> <layer>background</layer> <id>1</id> <text>pdate HistoryOct<a href="#" class="group"> 90: v1.0b1</a><a href="#" class="group">┬á┬á┬á┬áFi</a>rst ├ƒ releaseNov 90: v1.0b2ΓÇó┬á┬á┬áRenamed to Regions, less of a mouth/menu bar full than PictureObjects.ΓÇó┬á┬á┬áChanged menu from text to "tear-off" palette.ΓÇó┬á┬á┬áAdded idle script & idleTime properties.ΓÇó┬á┬á┬áAdded region dump ΓÇô builds a script to reconstruct region.ΓÇó┬á┬á┬áAdded ability to "send" to regions.ΓÇó┬á┬á┬áDocumented memLow/memAvail global properties.ΓÇó┬á┬á┬áFixed sticky buttons script.Dec90: v1.0b3ΓÇó┬á┬á┬áI've now got 2.5Mb of memory in my Plus!

Thank you.IntroductionRegion is a HyperCard 2.0 external command which implements region objects, normally abbreviated to just regions. A region is an arbitrary area, or collection of non-contiguous areas, which may contain holes; in which a picture is displayed. Before you can use regions the stack ΓÇ£Region XCMDΓÇ¥ must be ΓÇ£in useΓÇ¥ by HyperCard. This was done automatically when you opened this stack.Some ExamplesThe wandering Regions! to the right is a single region, with non-contiguous areas and holes. For a demonstration of a more ΓÇ£conventionalΓÇ¥ picture press: <a href="#" class="group">┬╖┬áCamel┬áΓÇÜ</a>, and a picture of a camel should appear. If you press the button more than once you can get a whole herd of camels (with the odd strangerΓÇª). If you now press: <a href="#" class="group">┬╖┬áClose┬áCamel┬áΓÇÜ</a> , then the first camel drawn will be removed, you can keep pressing until the whole herd has gone.</text> </content> <name></name>

This type of memory exhaustion cannot currently be predicted or recovered from. The problem is particularly acute on 1Mb systems and in colour modes. Used with reason there should be no problems, just don't ask for tens of flashing butterflies or too many owls!</text> </content> <name>Intro</name> <script>on openCardglobal introWindowsput the windows into introWindowsbuildBF1buildBF2end openCardon closeCardglobal introWindowscleanupWindows introWindowsend closeCardon buildBF1Region BF1,"-19,-18,154,111","Butterfly","Lasso"set the idle of window BF1 to "send toggleHilite to window targetRegion"set the idleTime of window BF1 to 300end buildBF1on buildBF2Region BF2,"367,73,540,202","Butterfly","Lasso"set the idle of window BF2 to "send toggleHilite to window targetRegion"set the idleTime of window BF2 to 500end buildBF2on buildBF3Region BF3,"-33,95,140,224","Butterfly","Lasso"set the idle of window BF3 to "send toggleHilite to window targetRegion"set the idleTime of window BF3 to 700end buildBF3on arrowKey whichif which is "Right" thensend mouseUp to btn "Next"elseif which is not "Left" thenpass arrowKeyend ifend ifend arrowKey</script> </card> card_8024.xml <?xml version="1.0" encoding="utf-8" ?> <!DOCTYPE card PUBLIC "-//Apple, Inc.//DTD card V 2.0//EN" "" > <card> <id>8024</id> <filler1>0</filler1> <cantDelete> <false /> </cantDelete> <showPict> <true /> </showPict> <dontSearch> <false /> </dontSearch> <owner>5931</owner> <link rel="stylesheet" type="text/css" href="stylesheet_3093.css" /> <name>Gray</name> <script></script> </card>
