Oval buttons

Hi: I'm still working away on my rebol scripts. Sometimes I think its getting easier, then I get stuck on some simple thing... I'm trying to make oval buttons, with their background the same color as the background of the rest of the face. If I do view layout [button 120x120 "test" with [effect: [0x1 oval 255.0.0] ] ] I would expect (at least, according to a line in one of the tutorials) to get an oval button on a background of red. Instead I get an oval button on a field of black. (with a blue edge) If I do view layout [button 120x120 "test" with [effect: [0x1 oval 0.255.255 ]] ] I get an oval button on a field of white. If I specify an edge view layout [button 120x120 "test" with [effect: [0x1 oval] edge: [color: 255.0.0 ] ] ] My edge is the color I specify, but the oval button is on a black background. If I specify both edge and oval color view layout [button 120x120 "test" with [effect: [0x1 oval 0.255.255 ] edge: [color: 255.0.0 ] ] ] I can get an oval with a white background and the edge I specify. But so far, I can't seem to figure out how to get the background field of the oval button to be what I actually want. --- What am I missing ? (BTW, because I need the Call command, I am using Rebol/View/Pro released version. I haven't tried any betas) Thanks, Andy

I'm guess this is a bug. I tried your example with the beta version of view, and the colors are what you expected, but when I run it on the 'official' view (non-pro), I always see the black background. With your last example, the cut-out area in the beta version is that slightly different yellow color, not black. So it looks like the color you set for the border should be used for the cut- out area as well. mike

Hi Andy, << (BTW, because I need the Call command, I am using Rebol/View/Pro released version. I haven't tried any betas) >> Try the latest releases (available at http://www.reboltech.com/downloads). Just put them in the same directory as your current version and give them different names. The pro features should be enabled if it can find your license key. Let me know if that works for you. --Gregg

by the way, I didn't need to use 'merge, it just worked for me as-is.

I have found the new effect pipeline in the betas so confusing I have given up before already, trying the same thing. Anyway, here is a round-about way of doing it, which works in REBOL/View 1.2.1.3.1 21-Jun-2001: img: to-image layout [ origin 0 image blue effect [oval key 0.0.0] ] view center-face layout [ button "hello" img edge [size: 0x0] ] To make the button change colour or image when you click on it, you are going to have to delve into the button more. But here's another way: view center-face layout [ button 100x50 black "hello" [print "hi"] edge [size: 0x0] effect [ draw [pen white circle 50x25 20 fill-pen red flood 50x25] key 0.0.0 ; (black) ] ] To get the colour to change when you click, you can set the 'effects facet: effect-blks: [ [draw [pen white circle 50x25 20 fill-pen red flood 50x25] key 0.0.0] [draw [pen white circle 50x25 20 fill-pen green flood 50x25] key 0.0.0] ] view center-face layout [ b: button 100x50 black "hello" [print "hi"] with [effects: effect-blks] edge [size: 0x0] ] Anton.

That's right. Do not be frightened, people. Hack away at the bleeding edge sometimes. Your license key will still work with the new betas. But, I can tell you have been beaten down by your experience with windows. Now you are frightened of what could happen if you install a program. :) Don't worry, I had the same worries, but this is rebol... The worst thing that could happen is a new rebol install can steal your .r file association and/or a registry entry specifying rebol home directory is changed. In this case, you can fix it by hand, just by searching through the registry for "rebol". You will come across the rebol home directory soon enough. I tested how rebol responds on a new system by simply renaming a rebol registry directory key. When rebol.exe ran, it couldn't find that directory in the registry anymore, so it assumed that it wasn't installed and opened the install window. Anton.

Hi Andy, On Thursday, September 5, 2002, 5:48:42 PM, you wrote: AF> I'm trying to make oval buttons, with their background the same color as AF> the background of the rest of the face. I think OVAL is not probably the effect you need; anyway, this should be close: view layout [box 50x50 255.0.0 effect [oval key 0.0.0]] I don't seem to be able to do the same with the BUTTON style, and I wonder why. I'll have to have a closer look at it. Regards, Gabriele. -- Gabriele Santilli <[g--santilli--tiscalinet--it]> -- REBOL Programmer Amigan -- AGI L'Aquila -- REB: http://web.tiscali.it/rebol/index.r
