Basic SDL Graphics

Testing some basic windo and rendering functions with SDL library in C++.

Notes

SDL lifecycle:

• SDL_Init
• SDL_Quit

Window management:

• SDL_CreateWindow
• SDL_DestroyWindow

Events

• SDL_PollEvent
  • returns SDL_Event - union of all event structures used in SDL

Rendering

• SDL_CreateRenderer - does the drawing
• SDL_CreateTexture -
• SDL_UpdateTexture -

Running the Example

See example.cpp for details. It links with the SDL library and uses a few informational APIs to get basic verification things are working.

A makefile compiles and runs the examples:

$ make
c++ -std=c++17 -Wall -O3 `sdl2-config --cflags --libs`    example.cpp   -o example
./example;

It generates an “abstract image”:
