    /// One difference from [`Dialog`][crate::Dialog] is that [`MessageDialog`][crate::MessageDialog] sets the

    /// from the taskbar by default.

    /// The easiest way to do a modal message dialog is to use [`DialogExt::run()`][crate::prelude::DialogExt::run()], though
    /// you can also pass in the [`DialogFlags::MODAL`][crate::DialogFlags::MODAL] flag, [`DialogExt::run()`][crate::prelude::DialogExt::run()] automatically
    /// makes the dialog modal and waits for the user to respond to it. [`DialogExt::run()`][crate::prelude::DialogExt::run()]
    /// returns when any dialog button is clicked.
    ///
    /// An example for using a modal dialog:
    ///

    /// **⚠️ The following code is in C ⚠️**
    ///
    /// ```C
