Description
For an Animation, the Align property may be 'None' or 'Centre' ('Center'). If Align is 'None', the Animation window is automatically resized to fit the AVI being played. If Align is 'Centre', the AVI is centred in the Animation window. If the window is too small, the AVI is clipped.
For a Button, Menu, or MenuItem the Align property may be 'None', 'Left' or 'Right'. If the Button Style is 'Radio' or 'Check' this property specifies the position of the text relative to the button symbol. The default is 'Right'. For a Button with Style 'Push', the value of Align is 'None'.
For a Button with Style 'Radio' or 'Check' that is created as a child of a Grid the value of the Align property may also be 'Centre' or 'Center'. Either of these values causes the symbol part of the Button (the circle or checkbox) to be centred within the corresponding Grid cell(s).
For a DateTimePicker, the Align property specifies the horizontal alignment of the drop-down Calendar which may be 'Left' (the default) or 'Right'. This applies only if the Style of the DateTimePicker is 'Combo'.
For a Menu, MenuItem, or StatusField, Align 'Right' is used to position the object at the right end of its parent MenuBar or StatusBar. 'None' is equivalent to 'Left' which is the default.
For objects of type CoolBar, Splitter, Scroll, StatusBar, TabBar, ToolBar and ToolControl, Align may be 'None', 'Top', 'Bottom', 'Left' or 'Right'. It specifies to which (if any) of the four sides of the parent the object is anchored and also the default position and size of the object. Specifying Align typically causes the Attach property to be set to appropriate values as follows :
| Align | Attach |
| 'Top' | 'Top' 'Left' 'Top' 'Right' |
| 'Bottom' | 'Bottom' 'Left' 'Bottom' 'Right' |
| 'Left' | 'Top' 'Left' 'Bottom' 'Left' |
| 'Right' | 'Top' 'Right' 'Bottom' 'Right' |
These settings cause the object to remain at a fixed distance (in pixels) from the corresponding edge of the parent. Furthermore, the object will have a fixed height or width, but its length will stretch and shrink as the Form is resized.
Note that this does not apply to a TabControl for which the default value of Attach is 'None' 'None' 'None' 'None', regardless of the value of Align.
The default value of Align is 'Right' for a vertical Scroll, 'Bottom' for a horizontal Scroll, and 'Top' for a CoolBar, TabBar, TabControl, ToolBar and ToolControl. Furthermore, unless Posn and Size are specified explicitly, the object is placed along the corresponding edge of its parent.
For a Scroll object, Align also determines the direction of a Scroll object unless it is overridden by setting HScroll or VScroll directly. If neither HScroll or VScroll is defined and Align is 'Top' or 'Bottom', a horizontal scrollbar is provided. If neither HScroll or VScroll is defined and Align is 'None', 'Left' or 'Right', a vertical scrollbar is provided.
The value of the Align property may only be assigned by ⎕WC and may not be changed using ⎕WS.
