I finally got around to writing a major mode for Qt .pro and .pri files. It doesn’t provide any indenting features; only font locking.

Just load it up and add the following to your .emacs

(require ‘qt-pro)
(add-to-list ‘auto-mode-alist ‘(“\\.pr[io]$” . qt-pro-mode))

Get it here qt-pro.el

A Simple SDL Demo that uses Hardware Acceleration and Double Buffering to draw
three Sphere images on the screen and bounce them around a bit.

It uses SDL_Image for loading the PNG file.

Copy and paste the source code to a file and compile it like this:

gcc -Wall -ansi -pedantic `sdl-config –cflags` -c bounce.c
gcc -Wall main.o -o main -lSDL_image -L/usr/X11R6/lib -L/usr/lib -lSDL -lpthread
