CENTER

blk2blue.jpg

The CENTER attribute (PROP:CENTER) indicates that the window's default position is centered. A WINDOW structure with the MDI attribute is centered on the APPLICATION. An APPLICATION structure is centered on the screen. A non-MDI WINDOW is centered on its parent (the window currently with focus when the non-MDI WINDOW is opened).

This attribute has no meaning unless at least one parameter of the AT attribute is omitted. This means that the CENTER attribute provides a default value for any omitted AT parameter.

For multi-monitor systems: Child and Owned Windows with the CENTER attribute (or PROP:CENTER = TRUE) applied are centered in the client area of their Parent/Owner window. Other windows with the CENTER attribute applied are centered in the monitor where most parts of the previous window in the same thread are displayed; if there are no other windows in the same thread, the window is displayed in the primary monitor.

Example:

WinOne WINDOW,AT(,,380,200),MDI,CENTER !Window centered relative to application frame

      END

WinTwo WINDOW,AT(,,380,200),CENTER     !Window centered relative to its parent:

      END
