Enhancements to Existing Motif Functionality

The Common Desktop Environment Xm library contains minor enhancements to Motif usability to enable better interoperability with OPEN LOOK and Microsoft Windows. The usability enhancements include:

• Optionally allowing mouse button 2 on a three-button mouse to be used to extend the current selection. This is equivalent to the OPEN LOOK Adjust function.

• Allowing Tab to be used to move through a group of PushButton widgets and gadgets, ArrowButton widget and gadgets, and DrawnButton widgets.

• Allowing mouse button 3 to activate a CascadeButton menu.

• Providing three new resources (pathMode, fileFilterStyle, and dirTextLabelString) for the XmFileSelectionBox widget, which give it an improved look and feel.

• Enabling interoperability with Microsoft Windows and OPEN LOOK through multiple virtual key bindings.

Each of the preceding enhancements can be controlled by a resource: either a widget resource (for XmFileSelectionBox) or an application-wide resource (all other cases). The default values for this resource provide behavior and APIs that are identical to that of Motif 1.2. For information on these enhancements and resources, see the XmDisplay(3x) and XmFileSelectionBox(3x) man pages.
