SDL2 TTF is a library that allows the use of TrueType fonts in SDL2 applications. Follow these steps to display text on a window using SDL2 TTF:
Install the SDL2 TTF library and include the necessary header files in your project.
Initialize SDL2 TTF. This can be done using the TTF_Init() function.
Load the font you want to use with the TTF_OpenFont() function. This function takes the font file name and font size as input parameters.
Create an SDLSurface to hold the text. This can be done using the TTFRenderText_Solid() function.
Create an SDLTexture from the surface with the SDLCreateTextureFromSurface() function.
Render the texture to the window using the SDL_RenderCopy() function.
Free the surface and texture, and close SDL2 TTF when finished.
Here's an example code snippet that displays the text "Hello, World!" on the screen in white color:
#include <SDL2/SDL.h>
#include <SDL2/SDL_ttf.h>
int main(int argc, char** argv) {
SDL_Init(SDL_INIT_VIDEO);
TTF_Init();
SDL_Window* window = SDL_CreateWindow("SDL2 TTF Example", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, 640, 480, 0);
SDL_Renderer* renderer = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED);
TTF_Font* font = TTF_OpenFont("Arial.ttf", 28);
SDL_Color color = { 255, 255, 255 };
SDL_Surface* surface = TTF_RenderText_Solid(font, "Hello, World!", color);
SDL_Texture* texture = SDL_CreateTextureFromSurface(renderer, surface);
SDL_Rect rect = { 100, 100, surface->w, surface->h };
SDL_RenderCopy(renderer, texture, NULL, &rect);
SDL_RenderPresent(renderer);
SDL_Delay(3000);
SDL_FreeSurface(surface);
SDL_DestroyTexture(texture);
TTF_CloseFont(font);
SDL_DestroyRenderer(renderer);
SDL_DestroyWindow(window);
TTF_Quit();
SDL_Quit();
return 0;
}
Note that this example assumes that the font file "Arial.ttf" can be found in the current working directory.
