# Text

A *text* widget manages a multi-line text area. Like the canvas widget, Tk's
text widget is an immensely flexible and powerful tool that can be used for a
wide variety of tasks. It can provide a simple multi-line text area as part of a
form. But text widgets can also form the basis for a stylized code editor, an
outliner, a web browser, and much more.

Note: Text widgets are part of the classic Tk widgets, not the themed Tk
widgets.

While we briefly introduced text widgets in an earlier chapter, we'll go into
more detail here. You'll get a better sense of the level of sophistication they
allow. Still, if you plan to do any significant work with the text widget, the
reference manual is a well-organized, helpful, and highly-recommended read.

```rust,no_run
parent.add_tk_text( "t" -width(40) -height(10) )?;
```

You'll often provide a width (in characters) and height (in lines). As always,
you can ask the geometry manager to expand it to fill the available space in the
window.
