# `wxGBSizerItem` [🔗](https://github.com/kikofernandez/otp/blob/kiko/otp/release-gh-action-backup-continuation/OTP-20040/lib/wx/src/gen/wxGBSizerItem.erl#L58) The `m:wxGBSizerItem` class is used by the `m:wxGridBagSizer` for tracking the items in the sizer. It adds grid position and spanning information to the normal `m:wxSizerItem` by adding `wxGBPosition` (not implemented in wx) and `wxGBSpan` (not implemented in wx) attributes. Most of the time you will not need to use a `m:wxGBSizerItem` directly in your code, but there are a couple of cases where it is handy. This class is derived, and can use functions, from: * `m:wxSizerItem` wxWidgets docs: [wxGBSizerItem](https://docs.wxwidgets.org/3.2/classwx_g_b_sizer_item.html) # `wxGBSizerItem` ```elixir -type wxGBSizerItem() :: wx:wx_object(). ``` --- *Consult [api-reference.md](api-reference.md) for complete listing*
