Struct TreeNode 

pub struct TreeNode<'a, T, L = &'static str> { /* private fields */ }

Builder for a tree node widget

Implementations

impl<'a, T: AsRef<str>> TreeNode<'a, T, &'static str>

pub fn label<L: AsRef<str>>(self, label: L) -> TreeNode<'a, T, L>

Sets a custom label for the tree node

impl<'a, T: AsRef<str>, L: AsRef<str>> TreeNode<'a, T, L>

pub fn opened(self, opened: bool, cond: Condition) -> Self

Sets the opened state

pub fn selected(self, selected: bool) -> Self

Draw as selected

pub fn framed(self, framed: bool) -> Self

Draw frame with background (e.g. for CollapsingHeader)

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

Hit testing to allow subsequent widgets to overlap this one

pub fn no_tree_push_on_open(self, no_push: bool) -> Self

Don’t do a TreePush() when open (e.g. for CollapsingHeader)

pub fn no_auto_open_on_log(self, no_auto: bool) -> Self

Don’t automatically and temporarily open node when Logging is active

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

Default node to be open

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

Need double-click to open node

pub fn open_on_arrow(self, arrow_only: bool) -> Self

Only open when clicking on the arrow part

pub fn leaf(self, leaf: bool) -> Self

No collapsing, no arrow (use as a convenience for leaf nodes)

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

Display a bullet instead of arrow

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

Use FramePadding to vertically align text baseline to regular widget height

pub fn span_avail_width(self, span: bool) -> Self

Extend hit box to the right-most edge

pub fn span_full_width(self, span: bool) -> Self

Extend hit box to the left-most and right-most edges

pub fn nav_left_jumps_back_here(self, nav: bool) -> Self

Left direction may move to this tree node from any of its child

pub fn push(self) -> Option<TreeNodeToken<'a>>

Pushes a tree node and starts appending to it.

Returns Some(TreeNodeToken) if the tree node is open. After content has been rendered, the token can be popped by calling .pop().

Returns None if the tree node is not open and no content should be rendered.

impl<'a, T: Clone, L: Clone> Clone for TreeNode<'a, T, L>

fn clone(&self) -> TreeNode<'a, T, L>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, T: Debug, L: Debug> Debug for TreeNode<'a, T, L>

fn fmt(&self, f: &mut Formatter<'_>) -> Result
