The Info Button: Display Information About Objects

The Info button brings up a window which displays information about selected objects, or alternatively allows information about selected objects to be dumped to a file. When the command is entered, if there are selected objects, the user is asked whether to dump the info to a file. If `y' is given to the prompt, the user is asked for a file name, and is given the option of viewing the file when the dump is complete.

If `n' is given at the first prompt, any selected objects become deselected. The user is prompted to click on objects, which will become selected. Only one object can be selected per pointer operation. After an object is selected, a text box appears which provides information about the object, such as the object type, bounding box, coordinates, etc.

If the Shift key is held while the user clicks anywhere in a drawing window, information about the current cell is provided.

By default, dimensions are given in microns. If the variable InfoInternal is set (with the !set command) then dimensions are given in internal units (1000 units per micron).

The text window contains two buttons. The Dismiss button removes the pop-up and exits info mode. The Activate button, which is initially active, can be used to exit and reenter info mode, while the pop-up remains visible.

When applied to polygons, the Info command performs reentrancy tests, and a message is added if the condition is found, i.e., if the polygon can not be rendered unambiguously.

The Info pop-up is also made visible by the Info button in the Cells Listing panel brought up by the Cells List button in the File Menu. When this button is used, previously selected objects are ignored, and there is no provision for dumping to a file. The Info window will provide information on cells selected in the cells listing, or on objects selected in the drawing windows.
