Win32 / Ili.............

An example of a real X program follows. This is about the simplest an X program is ever going to get. The program displays a small XPM image file in a window and waits for a key press or mouse click before exiting. You can compile it with gcc -o splash splash.c -lX11 -L/usr/X11R6/lib. (You can see right away why there are few applications written directly in X.) Notice that all X library functions are prefixed by an X.

You can learn to program X from the documentation in the X Window System sources--see below. The preceding program is said to be ``written directly in X-lib'' because it links only with the lowest-level X library, libX11.so. The advantage of developing this way is that your program will work across every variant of UNIX without any modifications. Notice also that the program deals with any type of display device regardless of its resolution (widthxheight or pixels-per-inch), color capacity, or hardware design.

може ли на български, че вече съм се превключил на него и не разбирам за какво става дума, но щом е на инлглизе - си е 15 зелени кинта в час ин адванс.


мързи ме да гледам след първия екран, все са същите боклуци
-----------------------
гърбавия, ковчег ще го изправи

дал си някакъв пример... което е добре.

а защо не драсна две думи отдолу та да знаем какво се опитваш да кажеш/докажеш?

Opitva se kaje (i e prav), che API-to na X11 ne e po-prosto za direktna upotreba, otkolkoto Windows GDI. Nishto novo, ele pyk interesno.

sledwashtia primer ste e iztegliane na jpg ot ftp site i vizualizirane.
stawa s 1 red na javascript :)
a w C e tolkowa uslojneno

от скоро си играя да правя гуи-та с python и Tk ( Tkinter ). голям кеф, супер лесно... и върви на юникси и уиндоуси

ама зависи какво ти трябва нали?
