# Creating The Tiles From C++ What we'll do is take the list of tiles declared in the .slint language, duplicate it, and shuffle it. We'll do so by accessing the `memory_tiles` property through the C++ code. For each top-level property, a getter and a setter function is generated - in our case `get_memory_tiles` and `set_memory_tiles`. Since `memory_tiles` is an array in the `.slint` language, it's represented as a [`std::shared_ptr`](https://slint.dev/docs/cpp/api/classslint_1_1model). We can't modify the model generated by the .slint, but we can extract the tiles from it, and put it in a [`slint::VectorModel`](https://slint.dev/docs/cpp/api/classslint_1_1vectormodel) which inherits from `Model`. `VectorModel` allows us to make modifications and we can use it to replace the static generated model. We modify the main function like so: ```cpp {{#include main_tiles_from_cpp.cpp:main}} ``` Running this gives us a window on the screen that now shows a 4 by 4 grid of rectangles, which can show or obscure the icons when clicking. There's only one last aspect missing now, the rules for the game.
