location

set [the] loc of button to point set [the] loc of field to point set [the] loc of window to point set [the] loc of externalWindow ¬ to point The location (or loc) property returns or sets the center point of a button or field and the top-left corner of a window. Setting the location of button, field, or window moves it to the new location.

HyperCard determines the location of buttons, fields, and HyperCard’s built-in windows relative to the top-left corner of the current card. For a window displaying a stack, HyperCard determines the location of the card window relative to the top-left corner of the screen with the menu bar. HyperCard adjusts the horizontal offset of the card window to the closest multiple of 16 to the number specified.

Examples

the location of card button 1
the loc of bkgnd field id 34
set the loc of bkgnd button "Next" to the clickLoc

the loc of card window

-- built-in windows:
the loc of message box
the loc of tool window

-- external windows:
set the loc of window "Script of stack My HD:Home" to 100,100

Item 1 of a point is the horizontal offset (in pixels). Item 2 of a point is the vertical offset (in pixels). For example:

91,303
"91,303"
"30" & "," & "100"
the clickLoc
AppleScript DefinitionAn expression that evaluates to a specific screen location, in the form of a list with two integer elements. For example:

{ 91, 303 }clickLoc

field
An expression that identifies a field by name, number, or id using one of the following forms (in AppleScript, use “background” in place of “bkgnd”):

card field id posInteger [of card ]card field text [of card ] -- namecard field posInteger [of card ]ordinal card field [of card ]

[bkgnd] field id posInteger [of card ][bkgnd] field text [of card ] -- name[bkgnd] field posInteger [of card ]ordinal [bkgnd] field [of card ]

For example:

card field id 3894
card field "My Notes"
card field 1
first card field
background field 3 of card 1
When used inside a field script in HyperTalk:

card window
tool window
window "tools"
pattern window
window "Patterns"
scroll window
window "scroll"
[the] message [window]
[the] message [box]

variable watcher
window "variable watcher"
window "Home"
window "Readymade Buttons"
-- if longWindowTitles is true:
window "My HD:Home"
window 6
window ID 21403082
Note: If a window containing a stack is inactive, you can set only its location and visible properties.
Important: External windows can’t be substituted for the window placeholder (see the externalWindow placeHolder).

externalWindow
