Remarks

Several properties are associated with each window: Rows, Columns, CursorRow, CursorColumn, CursorUpdate, CursorType, MarqueeFormat, MarqueeType, MarqueeUnitWait, MarqueeRepeatWait, and InterCharacterWait.

When the application sets CurrentWindow, it changes the current window (for display purposes) and sets the associated properties to their values for this window.

Setting a window does not refresh its viewport. If this window and another window’s viewports overlap, and the other window has changed the viewport, then the application can call the RefreshWindow method to restore this window’s viewport contents.

LineDisplayBase class verifies that the device has been opened, then retrieves or sets the value of LineDisplayProperties.CurrentWindow.

Accessing CurrentWindow may cause a PosControlException to be thrown with the following ErrorCode:

Value	Meaning
Illegal	CurrentWindow has been set to a value that isn’t valid.

CurrentWindow is initialized to 0 (zero) by the LineDisplayProperties class. If the value of CurrentWindow changes, the LineDisplayProperties class queues a CurrentWindowChangedEvent event to the service object.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread-safe. Any instance members are not guaranteed to be thread-safe.
