({{, (RefLink[$DisplayFunction, paclet:ref/$DisplayFunction])
gives the default setting for the option (RefLink[DisplayFunction, paclet:ref/DisplayFunction]) in graphics functions. }})

OpenersNotesSection(Spacer1)Details

For the Wolfram System used with a notebook front end, the typical default setting for (RefLink[$DisplayFunction, paclet:ref/$DisplayFunction]) is (RefLink[Identity, paclet:ref/Identity]).

When the Wolfram Language kernel is run on a raw terminal, (RefLink[$DisplayFunction, paclet:ref/$DisplayFunction]) typically uses (RefLink[ExportString, paclet:ref/ExportString]) and (RefLink[Print, paclet:ref/Print]), or sends to an external display program using (RefLink[Export, paclet:ref/Export]).

Use (RefLink[PopupWindow, paclet:ref/PopupWindow]) as the default (RefLink[DisplayFunction, paclet:ref/DisplayFunction]):

$DisplayFunction=(PopupWindow[Panel["Click here"],#]&);

Show[Graphics[{Pink,Rectangle[]}]]

Reset (RefLink[$DisplayFunction, paclet:ref/$DisplayFunction]):

$DisplayFunction=Identity;
