JAVA FlowLayout

The FlowLayout is the simplest layout manager. By default, it puts all the components into a row in the order they are added to the container from left-to-right. If the row meets the end of the container then a new row is started beneath.

Component Flow

The order of the components can be switched so that they appear from right-to-left by using the container's setComponentOrientation method:

JPanel buttonPanel = new JPanel();
buttonPanel.setComponentOrientation

(ComponentOrientation.RIGHT_TO_LEFT);

The setComponentOrientation method accepts the following field values from the ComponentOrientation class:

• LEFT_TO_RIGHT - components flow from the left-to-right.
• RIGHT_TO_LEFT - components flow from the right-to-left.
• UNKNOWN - specifies that the flow hasn't been set. In practice, if this value is set when the container is shown it will show a component flow of left-to-right.
