The icons described below permit you to make given frame types
invisible
, so-to-speak, and restore them later. This
electronic magic hat
has no other strategic purpose apart from
speeding up screen redraws. But of course you can also use it for
other creative purposes. A possible example is a questionnaire with
embedded answers. The questions would be placed in normal text frames,
the answer frames would be gathered together in a group frame. By
switching off the group frame you can then print out a questionnaire
without the answers.
There is little to say about operation: If the icon for a frame
type is selected (inverted) then frames of this type will be
displayed, otherwise only the outline of the frame appears (as long as
the Frame outline visible
function is switched on in the
Guidelines module). A click on the icon toggles between on and off,
i.e. visible and invisible.
When outputting a document that contains invisible frames, Calamus will ask whether all frames or only the visible ones are to be printed.
