`nk_style_slider` and `nk_style_scrollbar`'s `show_buttons` member typing is incorrect

Open Emily-TTG opened this issue 6 months ago • 2 comments

nk_style_slider and nk_style_scrollbar's show_buttons member is int instead of nk_bool. This causes an issue with nk_checkbox_label and the like where the passed pointer can cause a mismatch if NK_INCLUDE_STANDARD_BOOL is set.

This manifests in the configurator demo in both structures' respective functions.

Hello, @Emily-TTG. Thanks a lot for reporting this.

The underlying issue was introduced after PR #185 was merged. Besides that, it results in undefined behavior in style_configurator.c whenever nk_bool is redefined to a type other than int.
