dNode is a class within dTreeView.py
"class _dTreeView_test(dTreeView):" is a class that inherits from the class
dTreeView.
The dabo form is an instance of "TreeViewTestForm"
So let's follow the example.
def afterInit(self):
## create an instance of a panel
mp = dabo.ui.dPanel(self)
## add the panel to the form
self.Sizer.append1x(mp)
## define a sizer for the dabo panel we just added
sz = mp.Sizer = dabo.ui.dSizer("v")
## next we create a instance of the "_dTreeView_test"
## and we pass 'mp' a dabo panel to the class.
tree = self.tree = _dTreeView_test(mp)
## we better check out why we passed the panel.
## If we check out the class "_dTreeView_test" we discover
## there is no " __init__"
## Therefore the 'mp' must be passed to the class "dTreeView"
## the parent of "_dTreeView_test"
## Sure enough - there is an "__init__" and it needs at least one
## parameter the "parent". So we now why we passed
## 'mp'.
## let's continue with the "_dTreeView_test".
def afterInit(self):
## Wow somebody is getting tricky.
## They have created an instance of dNode by creating instance of "TestNode"
## and in "TestNode" we are just setting a few properties. Oh, we are getting
## deeper into to the world of OOP (watch your step). :-)
self.NodeClass = TestNode
## Oh what is this. Someone has decided to add a method to the
## "dTreeView" class for creating dummy data (maybe for testing).
## If you review what is in 'addDummyData' we discover that
## two ways of creating the nodes are shown - thanks for that.
self.addDummyData()
## the rest in "_dTreeView_test" is not to interesting.
self.expandAll() ....
## we followed the "_dTreeView_test" and have created the nodes (that includes
the root node)
## Let's now continue with our form "TreeViewTestForm"
## The next line after "tree = self.tree = _dTreeView_test(mp) "
## We add the just created tree to the sizer of the panel
## cool! Recall sz=mp.Sizer
sz.append1x(tree, border=12)
And as we say the rest is history.
