Module dom

Dom construction, NodeData and NodeType management functions

Re-exports

• pub use crate::id_tree::NodeHierarchy;
• pub use crate::id_tree::Node;
• pub use crate::id_tree::NodeId;

Structs

• CompactDom
  Same as Dom, but arena-based for more efficient memory layout
• Dom
  The document model, similar to HTML. This is a create-only structure, you don’t actually read anything back
• DomHash
  Calculated hash of a DOM node, used for querying attributes of the DOM node
• DomId
  DomID - used for identifying different DOMs (for example IFrameCallbacks) have a different DomId than the root DOM
• DomPtr
  Pointer to rust-allocated Box<Dom<*mut c_void>> struct
• NodeData
  Represents one single DOM node (node type, classes, ids and callbacks are stored here)
• ScrollTagId
  Same as the TagId, but only for scrollable nodes
• TagId
  Unique Ttag“ that is used to annotate which rectangles are relevant for hit-testing

Enums

• DomString
  Most strings are known at compile time, spares a bit of heap allocations - for &'static str, simply stores the pointer, instead of converting it into a String. This is good for class names or IDs, whose content rarely changes.
• EventFilter
  Sets the target for what events can reach the callbacks specifically.
• FocusEventFilter
  Event filter similar to HoverEventFilter that only fires when the element is focused
• HoverEventFilter
  Event filter that only fires when an element is hovered over
• NodeType
  List of core DOM node types built-into by azul.
• NotEventFilter
  The inverse of an onclick event filter, fires when an item is not hovered / focused. This is useful for cleanly implementing things like popover dialogs or dropdown boxes that want to close when the user clicks any where but the item itself.
• On
  When to call a callback action - On::MouseOver, On::MouseOut, etc.
• TabIndex
• WindowEventFilter
  Event filter that fires when any action fires on the entire window (regardless of whether any element is hovered or focused over).
