Optimized Scalar Functions

The following scalar primitive functions were optimized: addition, subtraction, multiplication, division, maximum, minimum, and identity.

New dyadic ŒUCS conversions

The dyadic ŒUCS system function allows you to convert between Unicode code points and various representations, such as UTF-8, UCS-2, and APL+Win ŒAV.

Two new states for the wrap property for the CommandBar class

The new ¯1 and 2 states allow you to explicitly specify that a child object of a command bar should be never wrapped (¯1) or always wrapped (2) regardless of the command bar's shape or orientation.

New barwrap property for the CommandBar class

The barwrap property controls wrapping of any children of the command bar. The values are the same as to those of the wrap property.

Bug Fixes

APL GUI

• There were numerous instances where the caption did not display at all or correctly for a command button (CommandButton class).
• A command button was not resized and painted correctly when shown after having been created on a closed form.
• When setting the wrap property for a command button, the command bar (CommandBar class) was not layed out correctly.
• The children of the frame in a command bar disappeared when the form was disabled and did not reappear when the form was re-enabled.
• The resize cursors for the mouse appeared when placing the mouse on the edge of a floating command bar with a single child control.
• The onHotChange handler stopped firing for a child Label control after having set any mouse event handler.
• Undocking and docking a command bar with a Frame and a child Combo control caused APL+Win to hang.
• Undocking then dragging a floating command bar with a Selector control caused the selector to disappear.
• The CommandButton control could be a child of another command button. This was incorrect behavior.
• The tooltip property didn't work for controls in a form that had its style property value set 16 (onTop).
• The media control's file property was updated eventhough the underlying MCI (Media Control Interface) player failed to open the file.
• The timer object's onTimer handler didn't occur when the DEP (Data Execution Prevention) option was enabled in the operating system.
• The def property gave "ŒWI DEF ERROR: Invalid object definition" error message when the argument was a definition vector that was of type HET.

Note: This update requires you have APL+Win 8.0, 8.1, or 8.2 installed on your machine.
