Description

Code generation for zinc windows A zinc window contains graphical objects similar to an canvas window. There are also binding for tags and transformations. Jeszra deals with transformations separately to coordinates! In consequence transformations are preserved during code creation.

The tags are different from canvas tags. Pathnames (.zinc.test for examples) should be avoided, since this may interfere with the 'pathtag' feature of zinc.

There is also a special tag 'current'; this tag is excluded from the code generation. The tag 'current' is added to the tags of the front most (under the pointer) item.

The '-clip' properties must be dealt with in a separate fashion. An Item which is used for clipping has to be part of the group to which it is applied (for clipping). This means the group must use 'itemconfigure -clip' after the item was created. The clipping item must also receive an variable which can then being used within the item configure call.

NOTE : First version does not include skip options These code generation is straight down the list of it's objects.

Groups are used within the geometry section as-well. therefore the graphical part has to be done before.

Bindtags may contain special groups such as 'current' Do not process this bindgroups instead remove them from the tags list.

Transformations are directly applied to the freshly created object as it is seen inside the zincwindow section.

Fixed, Z-Order.
