wxGUI API proposal

The proposal does not have to be complete and there can be several different proposals. (All can be listed in different sections on this page for now; if too long a subpage should be created and linked here.)

The API should be used for communication between objects in the wxGUI, for creating new GUI applications (and GUI addons/plugins) and for controlling the wxGUI from the embedded Python command line.

Short proposal based on the current state of refactoring

class Layer(object):

class LayerList(object):
    def GetSelectedLayers(self, checkedOnly=True):

# GrassInterface is a root in the tree of objects/interfaces which compose API
# provides the functionality which should be available to every GUI component
# and is expected to be passed to almost all objects
class GrassInterface:
    def RunCmd(self, *args, **kwargs):

    def Help(self, entry):

    def WriteLog(self, text, wrap=None, priority=1):
        """The meaning and usage of priority is not clear"""

    def WriteCmdLog(self, line, pid=None, switchPage=True):

    def WriteWarning(self, line):

    def WriteError(self, line):

    def GetLayerList(self):

    def GetMapDisplay(self):

    def GetAllMapDisplays(self):

    def GetMapWindow(self):

# more classes should be defined...
