SDL 如何检查窗口是最大化还是最小化

Question

我正在尝试制作一个可以最大化和最小化的无边框窗口，但我无法获得有关如何获取窗口当前状态(如果最小化或最大化(以及如何使用它的任何信息。

(编辑(代码的粗略片段：

SDL_Rect minimize_area = {0,0,20,20};
Button minimize_window_button = Button(minimize_area);
SDL_Rect maximize_area = {0,0,20,20};
Button maximize_window_button = Button(maximize_area);
SDL_Rect close_area = {0,0,20,20};
Button close_window_button = Button(close_area);
// Program loop
while ( SDL_PollEvent( &event ) ) {
case SDL_MOUSEBUTTONDOWN:
if (event.button.button == SDL_BUTTON_LEFT) {
mouse.updateMousePosition();
if (close_window_button.mouseInDstRect(mouse.pos.x, mouse.pos.y)) running = false;
if (maximize_window_button.mouseInDstRect(mouse.pos.x, mouse.pos.y)) {
if (/* WAY TO KNOW IF THE WINDOW IS MAXIMIZED */) {
SDL_MaximizeWindow(window);
} else {
SDL_RestoreWindow(window);
}
}
if (minimize_window_button.mouseInDstRect(mouse.pos.x, mouse.pos.y)) {
if (/* WAY TO KNOW IF WINDOW IS MINIMIZED or UNMINIMIZED */) {
SDL_MinimizeWindow(window);
} else {
SDL_RestoreWindow(window);
}
}
}
SDL_Log("click!");
break;
}

Answer 1

SDL_GetWindowFlags()，检查SDL_WINDOW_MINIMIZED位和SDL_WINDOW_MAXIMIZED位。
