public abstract class LayoutStyle
extends java.lang.Object

An abstract class that describes a layout and design style guide. It provides constants used to lay out panels consistently.

This class is work in progress and the API may change without notice. Therefore it is recommended to not write custom subclasses for production code. A future version of this class will likely collaborate with a class LogicalSize or StyledSize.

isLeftToRightButtonOrder

public abstract boolean isLeftToRightButtonOrder()

Checks and answers whether buttons are typically ordered from left to right or from right to left. Useful for building button bars that shall comply with the platform's layout style guide.

For example the Windows style guide recommends to layout out OK, Cancel, Apply from left to right, where the Mac Aqua style guide recommends to layout out these buttons from right to left.

Although most button sequences shall honor this order some buttons require a left to right order. For example Back, Next or Move Left, Move Right.

Returns:

true if buttons are typically ordered from left to right

Since:

1.0.3
