Struct TreeNode

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

Builder for a tree node widget

Implementations

impl<'a, T> TreeNode<'a, T>

where T: AsRef<str>,

pub fn new<I>(id: I, ui: &'a Ui) -> TreeNode<'a, T>

where I: Into<TreeNodeId<T>>,

👎Deprecated since 0.9.0: use ui.tree_node or ui.tree_node_config

Constructs a new tree node builder

impl<'a, T, L> TreeNode<'a, T, L>

where T: AsRef<str>, L: AsRef<str>,

pub fn label<I, L2>(self, label: L2) -> TreeNode<'a, T, L2>

where I: Into<TreeNodeId<L2>>, L2: AsRef<str>,

Sets the tree node label

pub fn opened(self, opened: bool, cond: Condition) -> TreeNode<'a, T, L>

Sets the opened state of the tree node, which is applied based on the given condition value

pub fn flags(self, flags: TreeNodeFlags) -> TreeNode<'a, T, L>

Replaces all current settings with the given flags.

pub fn selected(self, value: bool) -> TreeNode<'a, T, L>

Enables/disables drawing the tree node in selected state.

Disabled by default.

pub fn framed(self, value: bool) -> TreeNode<'a, T, L>

Enables/disables full-colored frame.

Disabled by default.

pub fn allow_item_overlap(self, value: bool) -> TreeNode<'a, T, L>

Enables/disables allowing the tree node to overlap subsequent widgets.

Disabled by default.

pub fn tree_push_on_open(self, value: bool) -> TreeNode<'a, T, L>

Enables/disables automatic tree push when the tree node is open (= adds extra indentation and pushes to the ID stack).

Enabled by default.

pub fn auto_open_on_log(self, value: bool) -> TreeNode<'a, T, L>

Enables/disables automatic opening of the tree node when logging is active.

By default, logging will automatically open all tree nodes.

Enabled by default.

pub fn default_open(self, value: bool) -> TreeNode<'a, T, L>

Sets the default open state for the tree node.

Tree nodes are closed by default.

pub fn open_on_double_click(self, value: bool) -> TreeNode<'a, T, L>

Only open when the tree node is double-clicked.

Disabled by default.

pub fn open_on_arrow(self, value: bool) -> TreeNode<'a, T, L>

Only open when clicking the arrow part of the tree node.

Disabled by default.

pub fn leaf(self, value: bool) -> TreeNode<'a, T, L>

Enable/disables leaf mode (no collapsing, no arrow).

Disabled by default.

pub fn bullet(self, value: bool) -> TreeNode<'a, T, L>

Display a bullet instead of arrow.

Disabled by default.

pub fn frame_padding(self, value: bool) -> TreeNode<'a, T, L>

Use frame_padding to vertically align text baseline to regular widget height.

Disabled by default.

pub fn nav_left_jumps_back_here(self, value: bool) -> TreeNode<'a, T, L>

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

Disabled by default.

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.

pub fn build<R, F>(self, f: F) -> Option<R>

where F: FnOnce() -> R,

Creates a tree node and runs a closure to construct the contents. Returns the result of the closure, if it is called.

Note: the closure is not called if the tree node is not open.
