Cadabra
Computer algebra system for field theory problems
|
Abstract base class with methods that need to be implemented by any GUI.
You need to derive from this class as well as from the DocumentThread class.

Add a GUI cell corresponding to the document cell at the iterator.
The GUI needs to figure out from the location of this cell in the DTree where to insert the cell in the visual display. If the 'visible' flag is false, hide the cell from view independent of whether its hidden flag is set (this is only used when constructing a document on load time and we do not want to show cells until they have all been added to the document).
Implemented in cadabra::NotebookWindow.

Network status is propagated from the ComputeThread to the.
GUI using the following methods. These get called on the compute thread (as opposed to the functions above, which get called on the gui thread).

When the ComputeThread needs to modify the document, it stores an ActionBase object on the stack (see the DocumenThread class) and then wakes up the GUI thread signalling it to process this action.
The following member should wake up the GUI thread and make it enter the processing part.

The basic manipulations that a GUI needs to implement are adding, removing and updating (refreshing the display of) a cell.
The code in DocumentThread will call these to make the GUI update its display. Called on the document thread.
