ui::CaptionInsets¶

Header: winui/ui/WindowShell.hpp.

The caption space a window with content extended into its title bar still has to leave alone (WindowStyle::extend_content_into_title_bar): the OS's caption buttons on one side, and on the other whatever the OS keeps there (nothing on a left-to-right window). DIPs, window-client coordinates. All zero when the content is not extended, so a TitleBar can bind to it unconditionally. Read through Window::caption_insets().

Example:

// Keep a custom title row clear of the caption buttons.
ui::Border{
    .padding = ui::bind(window.caption_insets(), [](const ui::CaptionInsets& c) {
        return ui::Edges{.left = c.left, .right = c.right}; }),
    .content = ui::Text{.text = "My app"},
}
