The Check In Foreground Button: Check Region or Cell

The Check In Foreground button initiates design rule checking on a region or cell. The user is requested to point to the corners of a rectangle defining the region to be checked. Simply clicking will cause checking of the objects under the pointer. Holding and dragging will cause checking of all objects which overlap the ghost-drawn rectangle, when the button is released. If the user presses and holds without moving the pointer for a brief period, the ghost-drawn rectangle corner will be attached to the pointer, and pressing a second time will complete the operation. Instead of a mouse button press, pressing the Enter key will cause the entire area of the current cell to be checked. All objects in the current cell and its subcells which overlap the specified region are checked. Errors are recorded in a file named ``drcerror.log'' which is written in the current directory. Additionally, violating objects are marked, and the error highlighted. During checking, button and key presses are locked out, however pressing Ctrl-C will abort the checking.
