Maybe in doc\gtapi.txt ?

Also Which > functions-methods are available for each of them? gtnul - base GT driver from which each other inherits. it gives screen buffer functionality but does not produce any screen output from disp*() commands Only outStd()/outErr() are supported. It's present on all platforms and i always linked. gtcgi - very simple GT driver which does not make any output formatting and simply send it as to stdout. Supported by all platforms. gtstd - it uses stdout output but tries to support full screen output but without collor support and cursor shape. It format text to number of row and columns if is able to detect these values on given platform. Supported by all platforms. gtpca - It's PCANSI terminal GT - it works in similar way to ANSI GT driver in Clipper though keyboard input is not fully supported. Now GTTRM can make all GTPCA job and much more. Supported by all platforms. gtdos - GT driver for DOS - it uses BIOS and direct hardware screen output so it's very similar to Clipper one - in practice due to the same environment you will noticed that all small details of Clipper GT drivers are replicated here. You can think about it like 100% Clipper compatible. Supported only by DOS builds. gtos2 - GT driver for OS2 - It's sth like GTWIN but for other OS. Supported only by OS2 builds. gtwin - GT driver for MS-Windows console window. Supported only by MS-WINDOWS (W95 or higher) builds. gtcrs - GT driver for platforms which supports curses or compatible (ncurses) library - in practice POSIX systems. Supported by POSIX systems (mostly different *nixes) gtsln - GT driver for platforms which supports slang library. It's like GTCRS but instead of CURSES it uses SLANG. Supported by POSIX systems (mostly different *nixes). It supports Unicode input/output if compiled with slang version which also supports it. gttrm - it's like GTCRS and GTSLN but it does not use any external terminal library like SLANG or CURSES and it does not use any external database to extract terminal capabilities so it can be compiled on any POSIX system - I'll add support also for DOS/Windows in the future. It should automatically detect UTF-8 terminal mode and switch internally to Unicode mode if necessary. In theory is less functional then GTCRS and GTSLN because I hard coded escape sequences only for few terminals but because I added support also for some non standard terminal extensions and I'm using very limited set of output sequences then it usually works better then GTCRS and GTSLN. Supported by POSIX systems (mostly different *nixes) gtwvt - GT driver for MS-Windows. It creates its own GUI window instead of using MS-console window. It allows to change font, window size, etc. Supported only by MS-WINDOWS (W95 or higher) builds. gtxwc - GT driver for X-Window. It's like GTWVT but for nixes. Additionaly it has set of predefined vector characters (box and arrowd drawing characters) which can be used instead of the one defined in font. It means that you will have all boxes and arrows you know from DOS ans CP437 even if you chose font which does not have them. Additionally it support some simple graphic output. See tests/gfx.prg for simple program which demonstrates it. Supported by POSIX systems (mostly different *nixes) gtalleg- GT driver which uses alegro library for input/output. It's also GUI driver which support HB_GFX*() drawing. Multi platform, works on all platforms for which allegro library has been ported: MS-Win, DOS, VESA, X11, FB, SDL, ... gtgui - pseudo GT driver which adds to GTNUL Clipboard and Tone functionality. If you are using some MS-Windows GUI library and you still want to use TONE() function or GTI_CLIPBOARD actions then link this GT driver with your application. If you do not want to use TONE() or GTI_CLIPBOARD then do not link it - it will be only waste of memory. gtctw - GT driver which adds CT3 Window functionality to any other GT driver from which it inherits. It's activated automatically when you execute first W*() function. In similar way in Harbour it's possible to add support for GTWVW inheriting from GTWVT. Some of the GT drivers support additional functionality with hb_gtInfo() interface. See include/hbgtinfo.ch for different actions. best regards, Przemek _______________________________________________ Harbour mailing list [email protected] http://lists.harbour-project.org/mailman/listinfo/harbour _______________________________________________ Harbour mailing list [email protected] http://lists.harbour-project.org/mailman/listinfo/harbour
