The RichTextArea control
([JDK-8301121](https://bugs.openjdk.org/browse/JDK-8301121)), or any custom
control that needs non-trivial navigation within complex or wrapped text needs
a public API to get information about text layout.
This change fixes the missing functionality by adding a new public method to
the `Text` and `TextFlow` classes.:
/**
* Obtains the snapshot of the current text layout information.
* @return the layout information
* @since 24
*/
public final LayoutInfo getLayoutInfo()
The immutable `LayoutInfo` structure contains information about:
- text lines: offsets and bounds
- overall layout bounds
TBD:
the platform can also report additional information such as:
- individual text lines' left and right side bearings (what are those?)
- text runs within each line
-------------
Commit messages:
- bounds
- draft api
