pub fn new(label: T) -> CollapsingHeader<T>

Constructs a new collapsing header builder

pub fn flags(self, flags: TreeNodeFlags) -> Self

Replaces all current settings with the given flags.

pub fn allow_item_overlap(self, value: bool) -> Self

Enables/disables allowing the collapsing header to overlap subsequent widgets.

pub fn default_open(self, value: bool) -> Self

Sets the default open state for the collapsing header.

Collapsing headers are closed by default.

pub fn open_on_double_click(self, value: bool) -> Self

Only open when the collapsing header is double-clicked.

pub fn bullet(self, value: bool) -> Self

Display a bullet instead of arrow.

Disabled by default.

pub fn frame_padding(self, value: bool) -> Self

pub fn begin(self, ui: &Ui) -> bool

Begins the collapsing header.

Returns true if the collapsing header is open and content should be rendered.

This is the same as build but is provided for consistent naming.

pub fn begin_with_close_button(self, ui: &Ui, opened: &mut bool) -> bool

Begins the collapsing header.

Returns true if the collapsing header is open and content should be rendered.

This is the same as build_with_close_button but is provided for consistent naming.

pub fn build(self, ui: &Ui) -> bool

Builds the collapsing header.
