Windows & displaysSDL 3.2
SDL_SetWindowTitle
Changes the text in the window's title bar.
Signature
bool SDL_SetWindowTitle(SDL_Window *window, const char *title);
How it works
Useful for showing the frame rate or the open file's name during development. Update it a few times per second at most: on some systems the call is slow.
Parameters
windowSDL_Window *
The window to rename.
titleconst char *
The new title, UTF-8. SDL copies it.
Return value
true on success, false on failure.
Example
example.cpp
1char title[64];
2SDL_snprintf(title, sizeof title, "Game - %.0f fps", fps);
3SDL_SetWindowTitle(window, title);
