arguments passed to gTree, for example, a name and/or class for the gTree that is created. |
The gTree has a childrenvp slot containing all viewports on the display list (including those that are popped). Every grob on the display list is made a child of the new gTree, with a vpPath in the vp slot so that the grob is drawn in the appropriate viewport.
In other words, the gTree contains all elements on the display list, but in a slightly altered form.
The gTree should produce exactly the same output as the display list.
A gTree object.
