Simulating SDL_WINDOWEVENT

Simulating an SDL_WINDOWEVENT is useful for testing how your application responds to window-related events. SDL supports event simulation through SDL_PushEvent().

Here’s an example of simulating a window resize event:

1SDL_Event resizeEvent;
2resizeEvent.type = SDL_WINDOWEVENT;
3resizeEvent.window.event =
4  SDL_WINDOWEVENT_RESIZED;
5resizeEvent.window.windowID =
6  SDL_GetWindowID(myWindow);
7resizeEvent.window.data1 = 1024;  // New width
8resizeEvent.window.data2 = 768;   // New height
9
10SDL_PushEvent(&resizeEvent);

Key Points

• Window ID: Ensure the windowID matches an actual SDL window.
• Event Data: Populate relevant fields, such as data1 and data2 for dimensions.

Testing Workflow

You can use this technique to simulate multiple scenarios, like minimizing, focusing, or resizing windows, without needing manual user input. Simulating events helps in automating tests for event-driven logic.

With proper event simulation, you can ensure your application behaves correctly under various conditions.
