Figure 4-8. A complex layout using various types of layout

mechanisms

The Panel Container

The Panel

container consists of a title bar, a caption, a status

message, a border, and a content area for its children. You can

use Panel containers to wrap self-contained application mod-

ules. You can control the display layout by using the layout

property set to vertical (the default), horizontal, or abso

lute. Each child must have its x and y positions set when using

an absolute layout, or they must use anchors for a constraint-

based layout.

Example 4-9 shows a sample Panel layout.
