autofit:AutoFitOptions: AutoFitOptions

Implementation

pub fn getFirstFittedRatio(self: *PanedWidget, autofit: AutoFitOptions) f32 {
    const content_size = switch (self.init_opts.direction) {
        .horizontal => self.data().contentRect().w,
        .vertical => self.data().contentRect().h,
    };
    // use the maximum possible handle margin to ensure we show all the content
    const total_pane_size = content_size - self.handleSize() * 2;

    const size_of_first = @max(autofit.min_size, switch (self.init_opts.direction) {
        .horizontal => self.layout.min_size_children.w,
        .vertical => self.layout.min_size_children.h,
    });
    return std.math.clamp(
        size_of_first / @max(1, total_pane_size),
        autofit.min_split,
        autofit.max_split,
    );
