Simulating SDL_WINDOWEVENT
How can I simulate a SDL_WINDOWEVENT
for testing purposes?
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:
SDL_Event resizeEvent;
resizeEvent.type = SDL_WINDOWEVENT;
resizeEvent.window.event =
SDL_WINDOWEVENT_RESIZED;
resizeEvent.window.windowID =
SDL_GetWindowID(myWindow);
resizeEvent.window.data1 = 1024; // New width
resizeEvent.window.data2 = 768; // New height
SDL_PushEvent(&resizeEvent);
Key Points
- Window ID: Ensure the
windowID
matches an actual SDL window. - Event Data: Populate relevant fields, such as
data1
anddata2
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.
