I know SDL_PushEvent could pass events between threads. And it useful for user events. But user data field contains fixed attrs (https://wiki.libsdl.org/SDL_UserEvent):
Uint32 type value obtained from SDL_RegisterEvents() Uint32 timestamp timestamp of the event Uint32 windowID the associated window, if any Sint32 code user defined event code void* data1 user defined data pointer void* data2 user defined data pointer
But if I want to pass some more data (for example string-code of purchased product and few additional attrs) I dynamycally create custom object and put the address to data1 or data2.
And after checking event with PollEvent in the SDL_main function thread I delete this dinamycally created object.
What is the best way to pass custom data with events? What technique do you use?
