Some handy functions for rearrangement of the tree. Returns the nodeselectiontype for the tree.ĬNode* ReplaceNode(CNode*, CString)void ReplaceNode(CNode*, CNode*)CNode* ReplaceSubTree(CNode*, CString)CNode* InsertNode(CNode*, CNode*, CString, DWORD ) Void GetNodeSelectionType(DWORD dwSelectType) Void SetNodeSelectionType(DWORD dwSelectType)
Selects the node pNode with nodeselectiontype dwSelectType. Void SelectNode(CNode* pNode, DWORD dwSelectType) The node-selection type (one of NS_*, see node.h).Ĭreates a tree with a root node of type strType. The core-classes with there attributes and methods look as follow: CBinTree CNode* m_pRootNode
#Coteditor compile code
The resources for the toolbar of the formula-dialog are included via compiletime-directives ( resource includes-submenu in the view -menu of the developer-studio)Ĭopy Code #include " FormulaDlg.h" void CMainFrame::OnFormula() If you want to use this code in your project you only have to import the classes and to call the DoModal-method of the FormulaDlg.Please be careful with the resources. Any suggestions and refinements are welcome. Please see the implemented TransformRect and DrawContent methods as an example! There are a lot of ways to code them much better. Table 1) List of already integrated nodes and their dependecies Here is a list of them and ther interdependencies: Please have a look on the implementation of the already integrated nodes for further details. Handle the ToolBarCtrlSelected Event for your node (in the FormulaDlg_ToolBar.cpp file).Insert a new button into a already present ToolbarBtn or build a new ToolbarBtn with your own node.Virtual void DrawContent(CDC* pDC, CRect rect, DWORD dwSelect) Virtual void TransformRects(CRect& ,CRect& ,CRect& ,CRect& ) Virtual void Serialize(CArchive& ar, CBinTree* pTree) Declare a new node-entity in the nodeentities.h (derive it public from CNode).Define a new node-type (insert a new unique NT_* define into the node.h).If you want to integrate a new node you have to do the following steps: (draw my left child on the left, draw my right child on the right and draw my own content into the middle). The base class CNode was originally designed as an abstract base class, but it currently provides the standard behaviour of a node. the extraction of the content is performed by an inorder-traversal through the binary tree. The basic approach of the formula-editor is the representation of mathematical content in a binary-tree data-structure.

Alexander Bischofberger ( CColourPopup),.Chris Maunder ( CGridCtrl, CColourPopup),.Parts of the code are based on the work of Therefore we developed a set of classes described below. We needed a mathematical formula editor that was able to export the content of the formulas into a programming language (FORTRAN 77 in our case).
