## 6.1 Getting Started

items

A canvas widget displays items. An item is created with the `create` command, followed by coordinates and options. The number of coordinates and the options depend on the particular type of item to be created. An item is of one the following types:

`arc`

  An arc item displays a piece of a circle.

`bitmap`

  A bitmap item displays a bitmap with a given name.

`image`

  Displays an image.

`line`

  A line item consists of several connected segments. It is possible to configure line items such that Bézier splines are used.

`oval`

  An oval can either be a circle or an ellipsis.

`polygon`

  A polygon is described by three or more line segments. As with line items, it is possible to use Bézier splines.

`rectangle`

  Displays a rectangle.

`text`

  Displays text consisting of a single or several lines.

`window`

  Displays a widget in the canvas where the canvas widget serves as geometry manager for the widget.

For example,

  `C={New Tk.canvas tkInit(parent:W)}
  {Tk.send pack(C)}
  {C tk(create rectangle 10 10 1#c 1#c fill:red outline:blue)}`

creates a red rectangle with a blue outline near to the upper left corner of the canvas widget `C`. More information on the different items can be found in `canvas`.
