The Yoix^® Scripting Language

The rules that must be followed when accelerator is a string are strict and are imposed by the Java class java.awt.AWTKeyStroke that is used to parse the string. Modifiers, if there are any, come first and must be a space separated combination of the case-sensitive words ctrl, control, shift, meta, alt, and altGraph. An upper-case token that follows the modifiers must be the name of the key, as it appears in the KeyCode dictionary that can be found in yoix.awt or yoix.swing, but without the leading VK_ prefix that can be pressed, along with the modifiers, to trigger the event handler call. The case-sensitive words pressed or released can appear between the modifiers and upper-case keycode to specify exactly when the event handler is called. Alternatively the modifiers can be followed by the word typed, a space, and a single character if you want the event handler to be called when that character is typed.

Reading returns the current cursor. Writing immediately changes the menuitem's cursor to the new value. Storing STANDARD_CURSOR (the default) or NULL in cursor is special and means use the cursor assigned to the nearest component that contains the menuitem and was assigned a cursor other than STANDARD_CURSOR; if no component qualifies the menuitem uses DEFAULT_CURSOR.

Swing components that provide automatic drag handling start out with a transferhandler field that is not NULL, but the automatic drag handling is not enabled until 1 is stored in dragenabled. Swing components that provide their own drag and drop event handlers currently must store NULL in transferhandler before those event handlers will start working.
