"""

|
|
Regression test for issue #318 -- GridView.texture always returned None.
|
||
|
|
|
||
|
|
Root cause: the getter had a `TODO: return texture wrapper` and fell through to
|
||
|
|
Py_RETURN_NONE even when self->data->ptex was non-null. The fix returns a
|
||
|
|
Texture wrapper sharing the underlying shared_ptr<PyTexture>, mirroring
|
||
|
|
UIGrid.texture.
|
||
|
|
|
||
|
|
Needs an asset; run via run_tests.py (cwd=build/) or from build/ so that
|
||
|
|
assets/kenney_tinydungeon.png resolves. ASCII-only. Prints PASS/FAIL + exit.
