RE: [lazarus] ColorToRGB in console app
Hi Graeme, Thanks for the tips. Console apps with the Laz GUI linked in (i.e., linked against a widgetset via inclusion of interfaces unit) work fine on Windows and Carbon and even with GTK on OS X if run in an X termimal. However, I would like to be able to have a truer console app (and a much smaller one too). ColorToRGB is widgetset-dependent so I can't use that if I want a true console app. Another problem I've run into is trying to decide what RGB value to use for color constants. For example, ColorToRGB(clBtnFace) returns different RGB values on Windows, OS X Carbon and OS X GTK, as implemented by the widgetsets' GetSysColor. Probably different values would also be returned on the same platform depending on user preferences too. So I guess my problem is how to map color constants for use, say, in other programs or in a Web browser. Maybe just use a default Windows set of RGB values or something would make sense. Thanks. -Phil -Original Message- From: Graeme Geldenhuys [mailto:[EMAIL PROTECTED] Sent: Monday, February 11, 2008 2:09 AM To: lazarus@miraclec.com Subject: Re: [lazarus] ColorToRGB in console app On 10/02/2008, Hess, Philip J <[EMAIL PROTECTED]> wrote: > > Of course, now the app has the same issues as any Mac GUI app compiled with > GTK, in that even though it's a console app (sort of), it will only run under X11.

You can't include the 'interfaces' unit in a console application because it requires (pulls in) GUI code. You will not notice anything under Windows, because Windows always has a GUI installed. Under Linux it's easily noticed when you don't run a X Server and try an execute a console application that uses 'interfaces' unit. I had this same issue in the tiOPF project and console unit tests on my Linux server which doesn't run a X Window server installed. Some unit tests required the clipboard, which is a GUI feature in LCL or VCL.

If you pass in a cl color alias (like clBtnFace etc) you first need to lookup the RGB equivalent color value via ColorToRGB.

When someone asks on this list about 'console app runs okay on Delphi' I assume he wants a short answer to get something Delphi compatible and not a long answer about pros and cons.

Or don't you get Mac OS X servers? So even though Macs use the *BSD OS (forgot it's name) as the underlying OS, you can't install without a GUI? As you can guess I know next to nothing about Macs.

You do not get true console applications under Windows, because all windows installations have a GUI installed. You can access for example the clipboard in a console application under Windows, but you can't under a true Linux console application. You will have to implement the color conversion yourself. Below is some code I use in fpGUI. Just remember that in fpGUI the TfpgColor type is define as RRGGBB, but under Delphi (and Lazarus) TColor is defined as BBGGRR due to Windows. function fpgColorToRGBTriple(const AColor: TfpgColor): TRGBTriple; begin with Result do begin Red := fpgGetRed(AColor); Green := fpgGetGreen(AColor); Blue := fpgGetBlue(AColor); //Alpha := fpgGetAlpha(AColor); end end; function RGBTripleTofpgColor(const AColor: TRGBTriple): TfpgColor; begin Result := AColor.Blue or (AColor.Green shl 8) or (AColor.Red shl 16);// or (AColor.Alpha shl 32); end; function fpgGetRed(const AColor: TfpgColor): word; begin // AARRGGBB format Result := Word((AColor shr 16) and $FF); end; function fpgGetGreen(const AColor: TfpgColor): word; begin // AARRGGBB format Result := Word((AColor shr 8) and $FF); end; function fpgGetBlue(const AColor: TfpgColor): word; begin // AARRGGBB format Result := Word(AColor and $FF); end; Regards, - Graeme - ___ fpGUI - a cross-platform Free Pascal GUI toolkit http://opensoft.homeip.net/fpgui/ _ To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

RE: [lazarus] ColorToRGB in console app
Excellent, that's what I was forgetting. Of course, now the app has the same issues as any Mac GUI app compiled with GTK, in that even though it's a console app (sort of), it will only run under X11. And no way to compile for Carbon with lazbuild unless the framework carbon stuff already set in the .lpi. Also, looking at some of the functions in Graphics.pp, I wonder if it's confusing to use TColor for params with functions like RedGreenBlue, InvertColor, etc. TColor can be a full RGB value _or_ a color constant like clBtnFace (value of 15). If someone passes a color constant to one of these functions, they'll get an unexpected result. So it seems as though RedGreenBlue, etc. should either call ColorToRGB first or else the param type should be LongInt or something to make it clearer that a color constant should not be passed. Same with ColorToRGB - in Delphi the return type is LongInt, not TColor, since it only returns RGB values, not color constants.
