Specifies the pattern used to draw a three-D object's raised edge.Syntax:

set the topPattern of <object> to {<patternNumber> | <imageID> | empty}

Examples:

set the topPattern of the mouseControl to 22
set the topPattern of field "List" to the topPattern of me

Objects whose threeD property is set to true appear to stick out of or recede into the screen. Use the topPattern property to specify the pattern used to draw the raised edge of the object(glossary).

Pattern images can be color or black-and-white.

To be used as a pattern on Mac OS
systems, an image must be 128x128 pixels or less, and both its

height and width must be a power of 2. To be used on Windows and Unix systems, height and width must be divisible by 8. To be used as a fully cross-platform pattern, both an image's dimensions should be one of 8, 16, 32, 64, or 128.

The topPattern of controls is drawn starting at the control's upper right corner: if the control(keyword) is moved, the pattern does not shift.

Setting the topPattern of an object(glossary) to empty allows the topPattern of the object's owner to show through. Use the effective keyword to find out what pattern is used for the object(glossary), even if its own topPattern is empty.

If the object's showBorder property is false, the topPattern has no effect.

The setting of the topPattern property has different effects, depending on the object type:

  • The topPattern of a stack determines the topPattern of each
 object(glossary) in the stack that does not have its own
 topPattern. 


  • The topPattern of a card determines the pattern of the border on
 the top and left edges of the card, as well as determining the
 topPattern of each object(glossary) on the card that does not
 have its own topPattern.


  • The topPattern of a group determines the pattern of the border on
 the bottom and right edges of the group, as well as determining
 the topPattern of each object(glossary) in the group that does
 not have its own topPattern.


  • The topPattern of a button(keyword) forms a border on the top and
 left edges of the button(keyword). If the button's
 threeD property is false, the topPattern has no effect.


  • The topPattern of a field(keyword) forms a border on the bottom
 and right edges of the field(keyword) and (if the field(keyword)
 is a scrolling field(keyword)) the top and left edges of the arrow
 boxes at the ends of the scrollbar and the bottom and right edges of
 the scroll area. The field's topPattern also
 determines the pattern of the top and left edges of any text in the
 field(keyword) whose textStyle is set to "threeDBox". If the
 field's threeD property is false, the
 field(keyword) border is not affected.


  • The topPattern of a scrollbar forms a border on the top and left
 edges of the arrow boxes at the ends of the scrollbar, and the
 bottom and right edges of the scroll area.

 the bottom and right edges of the object(glossary). If the object's
 threeD property is false, the topPattern has no effect.


If an object's topPattern is set, the pattern is shown instead of the color specified by the topColor.
