AIX Version 4.3 Differences Guide

• Since the check mark sign is particular to the US, for other cultures check
boxes can be crossed instead.
• In addition to the regular button colors, two additional colors can be used to
indicate On or Off.
• In radio boxes, a circular shape can be used instead of the diamond shape.
An example of the new toggle buttons are shown in Figure 47 in the upper-left
and right corners.
8.3.4.6 Support for Right-to-Left Layout
Support has been added for languages written from right to left. Many of the Motif
widgets now automatically reverse the geometry when the direction is
right-to-left. For example, the Form widget automatically switches the left margin
and the right margin, as well as the attachment constraints. The result is that
developers can design applications using the internationalization facilities and
specify a constrained layout that will work in both left-to-right and right-to-left
environments.
8.3.4.7 Support for XPM Format
Motif 2.1 requires that applications are linked with the Xpm library. This library is
freely available from the /contrib directory of the X Consortium and is also
duplicated on the Motif tape. Xpm support makes it possible to support multi-color
pixmap icons instead of two-color bitmaps.
8.3.4.8 Vertical Paned Window
The Motif 1.x Paned Window widget can only have horizontally-separated panes.
Motif 2.1 adds a vertical mode.
8.3.4.9 Unit Conversion
New conversion methods have been added so that a user can specify a window
size in inches, millimeters, or typographical points.
8.3.4.10 List Enhancements
When a selection is made from XmList, a new resource specifies whether XmList
takes ownership of the primary selection. A keyboard navigation facility was
added allowing the user to navigate directly to an item by typing the first
character of that item. This is useful in lists organized in alphabetical order.
The Motif 1.2 List widget does not exhibit very good startup performance with
large lists. An optimization was found in the algorithms and memory allocation
strategy that reduces the startup time of a List widget by more than 30 percent on
a typical workstation.
8.3.4.11 XmScreen Enhancements
Several resources have been added to the XmScreen widget to allow per-screen
behavior.
A new resource is available to specify whether pixmaps or bitmaps should be
used in an application. If bitmaps are used, the application is limited to two-color
icons, or stipples, and it uses much less memory (typically eight times less on
8-bit color screens).
