Unless you call ->close() twice ?

Graphics / Behaviour of the standard "input -> update -> render" after RenderWindow closing
« on: December 27, 2018, 09:54:02 am »
Hi !
In my projects, I tend to use the standard "ProcessInputs" -> "Update" -> "RenderFrame" loop.
Today however, I noticed that I usually drop a `renderWindow->close()` statement inside the "Update()" method, which is ran before the "RenderFrame()" method in every loop. In addition to that, I do not perform any check to see if the window is still open in the "RenderFrame()" method, simply assuming the window will be open.
...but it shouldn't be, and I almost never have issues with having a "RenderFrame()" called, that in turn calls `renderWindow->clear()`, `renderWindow->draw(...)`, and `renderWindow->display()` without checks.
How is that possible ? What does actually `renderWindow->close()` do ? Does it close instantly or does it wait for the next "clear/display" ?
Or perhaps do the "clear()" and "display()" methods check for the renderWindow's availability ?
Thanks for enlightnening me !
...And merry Christmas !
