+\chapter{OGLEdit: a sample OGL application}\label{ogledit}%
+\setheader{{\it CHAPTER \thechapter}}{}{}{}{}{{\it CHAPTER \thechapter}}%
+\setfooter{\thepage}{}{}{}{}{\thepage}
+
+OGLEdit is a sample OGL application that allows the user to draw, edit,
+save and load a few shapes. It should clarify aspects of OGL usage, and
+can act as a template for similar applications. OGLEdit can be found in\rtfsp
+{\tt samples/ogledit} in the OGL distribution.
+
+$$\image{10cm;0cm}{ogledit.eps}$$\par
+
+The wxWindows document/view model has been used in OGL, to reduce the amount of
+housekeeping logic required to get it up and running. OGLEdit also provides
+a demonstration of the Undo/Redo capability supported by the document/view classes,
+and how a typical application might implement this feature.
+
+{\it Note:} A bug in the wxWindows document/view implementation before
+version 1.66C may cause Do/Undo to misbehave and get out of sync. If this is the case,
+please replace wxCommandProcessor::Submit with the following in wx\_doc.cpp.
+
+{\small
+\begin{verbatim}
+ Bool wxCommandProcessor::Submit(wxCommand *command, Bool storeIt)
+ {
+ Bool success = command->Do();
+ if (success && storeIt)
+ {
+ if (commands.Number() == maxNoCommands)
+ {
+ wxNode *firstNode = commands.First();
+ wxCommand *firstCommand = (wxCommand *)firstNode->Data();
+ delete firstCommand;
+ delete firstNode;
+ }
+
+ // Correct a bug: we must chop off the current 'branch'
+ // so that we're at the end of the command list.
+ if (currentCommand)
+ {
+ wxNode *node = currentCommand->Next();
+ while (node)
+ {
+ wxNode *next = node->Next();
+ delete node;
+ node = next;
+ }
+ }
+
+ commands.Append(command);
+ currentCommand = commands.Last();
+ SetMenuStrings();
+ }
+ return success;
+ }
+\end{verbatim}
+}
+
+\section{OGLEdit files}
+
+OGLEdit comprises the following source files.
+
+\begin{itemize}\itemsep=0pt
+\item doc.h, doc.cpp: MyDiagram, DiagramDocument, DiagramCommand, MyEvtHandler
+classes related to diagram functionality and documents.
+\item view.h, view.cpp: MyCanvas, DiagramView classes related to visualisation of
+the diagram.
+\item ogledit.h, ogledit.cpp: MyFrame, MyApp classes related to the overall application.
+\item palette.h, palette.cpp: EditorToolPalette implementing the shape palette.
+\end{itemize}
+
+\section{How OGLEdit works}
+
+OGLEdit defines a DiagramDocument class, each of instance of which holds a MyDiagram
+member which itself contains the shapes.
+
+In order to implement specific mouse behaviour for shapes, a class MyEvtHandler is
+defined which is `plugged into' each shape when it is created, instead of overriding each shape class
+individually. This event handler class also holds a label string.
+
+The DiagramCommand class is the key to implementing Undo/Redo. Each instance of DiagramCommand
+stores enough information about an operation (create, delete, change colour etc.) to allow
+it to carry out (or undo) its command. In DiagramView::OnMenuCommand, when the user initiates the
+command, a new DiagramCommand instance is created which is then sent to the document's
+command processor (see wxWindows manual for more information about doc/view and command
+processing).
+
+Apart from menu commands, another way commands are initiated is by the user left-clicking on
+the canvas or right-dragging on a node. MyCanvas::OnLeftClick in view.cpp shows how
+the appropriate wxClassInfo is passed to a DiagramCommand, to allow DiagramCommand::Do
+to create a new shape given the wxClassInfo.
+
+The MyEvtHandler right-drag methods in doc.cpp implement drawing a line between
+two shapes, detecting where the right mouse button was released and looking for a second
+shape. Again, a new DiagramCommand instance is created and passed to the command
+processor to carry out the command.
+
+DiagramCommand::Do and DiagramCommand::Undo embody much of the
+interesting interaction with the OGL library. A complication of note
+when implementing undo is the problem of deleting a node shape which has
+one or more arcs attached to it. If you delete the node, the arc(s)
+should be deleted too. But multiple arc deletion represents more information
+that can be incorporated in the existing DiagramCommand scheme. OGLEdit
+copes with this by treating each arc deletion as a separate command, and
+sending Cut commands recursively, providing an undo path. Undoing such a
+Cut will only undo one command at a time - not a one to one
+correspondence with the original command - but it's a reasonable
+compromise and preserves Do/Undo whilst keeping our DiagramCommand class
+simple.
+
+\section{Possible enhancements}
+
+OGLEdit is very simplistic and does not employ the more advanced features
+of OGL, such as:
+
+\begin{itemize}\itemsep=0pt
+\item attachment points (arcs are drawn to particular points on a shape)
+\item metafile and bitmaps shapes
+\item divided rectangles
+\item composite shapes, and constraints
+\item creating labels in shape regions
+\item arc labels (OGL has support for three movable labels per arc)
+\item spline and multiple-segment line arcs
+\item adding annotations to node and arc shapes
+\item line-straightening (supported by OGL) and alignment (not supported directly by OGL)
+\end{itemize}
+
+These could be added to OGLEdit, at the risk of making it a less
+useful example for beginners.

+\chapter{Topic overviews}
+\setheader{{\it CHAPTER \thechapter}}{}{}{}{}{{\it CHAPTER \thechapter}}%
+\setfooter{\thepage}{}{}{}{}{\thepage}
+
+The following sections describe particular topics.
+
+\section{OGL overview}\label{ogloverview}
+
+\helpref{wxShapeCanvas}{wxshapecanvas}, derived from {\bf wxCanvas}, is the drawing area
+for a number of \helpref{wxShape}{wxshape} instances. Everything drawn on a
+wxShapeCanvas is derived from wxShape, which provides virtual
+member functions for redrawing, creating and destroying
+resize/selection `handles', movement and erasing behaviour, mouse
+click behaviour, calculating the bounding box of the shape, linking
+nodes with arcs, and so on.
+
+The way a client application copes with `damage' to the canvas is to
+erase (white out) anything should no longer be displayed, redraw the shape,
+and then redraw everything on the canvas to repair any damage. If quick edit
+mode is on for the canvas, the complete should be omitted by OGL and the
+application.
+
+Selection handles (called control points in the code) are implemented as
+wxRectangleShapes.
+
+Events are passed to shapes by the canvas in a high-level form, for example {\bf OnLeftClick},
+{\bf OnBeginDragLeft}, {\bf OnDragLeft}, {\bf OnEndDragLeft}. The canvas decides
+what is a click and what is a drag, whether it is on a shape or the canvas itself,
+and (by interrogating the shape) which attachment point the click is associated with.
+
+In order to provide event-handling flexibility, each shapes has an `event handler' associated with it,
+which by default is the shape itself (all shapes derive from wxShapeEvtHandler).
+An application can modify the event-handling behaviour simply by plugging a new
+event handler into the shape. This can avoid the need for multiple inheritance when
+new properties and behaviour are required for a number of different shape classes: instead
+of overriding each class, one new event handler class can be defined and used for all
+existing shape classes.
+
+A range of shapes have been predefined in the library, including rectangles, ellipses,
+polygons. A client application can derive from these shapes and/or derive entirely
+new shapes from wxShape.
+
+Instances of a class called \helpref{wxDiagram}{wxdiagram} organise collections of
+shapes, providing default file input and output behaviour.
+
+
+\section{wxDividedShape overview}\label{dividedshapeoverview}
+
+Classes: \helpref{wxDividedShape}{wxdividedshape}
+
+A wxDividedShape is a rectangle with a number of vertical divisions. Each
+division may have its text formatted with independent characteristics, and
+the size of each division relative to the whole image may be specified.
+
+Once a wxDividedShape has been created, the user may move the divisions with the
+mouse. By pressing Ctrl while right-clicking, the region attributes can be edited.
+
+Here are examples of creating wxDividedShape objects:
+
+{\small
+\begin{verbatim}
+ /*
+ * Divided rectangle with 3 regions
+ *
+ */
+
+ wxDividedShape *dividedRect = new wxDividedShape(50, 60);
+
+ wxShapeRegion *region = new wxShapeRegion;
+ region->SetProportions(0.0, 0.25);
+ dividedRect->AddRegion(region);
+
+ region = new wxShapeRegion;
+ region->SetProportions(0.0, 0.5);
+ dividedRect->AddRegion(region);
+
+ region = new wxShapeRegion;
+ region->SetProportions(0.0, 0.25);
+ dividedRect->AddRegion(region);
+
+ dividedRect->SetSize(50, 60); // Allow it to calculate region sizes
+ dividedRect->SetPen(wxBLACK_PEN);
+ dividedRect->SetBrush(wxWHITE_BRUSH);
+ dividedRect->Show(TRUE);
+ dividedRect->NameRegions();
+
+ /*
+ * Divided rectangle with 3 regions, rounded
+ *
+ */
+
+ wxDividedShape *dividedRect3 = new wxDividedShape(50, 60);
+ dividedRect3->SetCornerRadius(-0.4);
+
+ region = new wxShapeRegion;
+ region->SetProportions(0.0, 0.25);
+ dividedRect3->AddRegion(region);
+
+ region = new wxShapeRegion;
+ region->SetProportions(0.0, 0.5);
+ dividedRect3->AddRegion(region);
+
+ region = new wxShapeRegion;
+ region->SetProportions(0.0, 0.25);
+ dividedRect3->AddRegion(region);
+
+ dividedRect3->SetSize(50, 60); // Allow it to calculate region sizes
+ dividedRect3->SetPen(wxBLACK_PEN);
+ dividedRect3->SetBrush(wxWHITE_BRUSH);
+ dividedRect3->Show(TRUE);
+ dividedRect3->NameRegions();
+\end{verbatim}
+}
+
+
+\section{wxCompositeShape overview}\label{compositeshapeoverview}
+
+Classes: \helpref{wxCompositeShape}{wxcompositeshape}, \helpref{OGLConstraint}{oglconstraint}
+
+The wxCompositeShape allows fairly complex shapes to be created, and maintains
+a set of constraints which specify the layout and proportions of child shapes.
+
+Add child shapes to a wxCompositeShape using \helpref{AddChild}{wxcompositeshapeaddchild}, and
+add constraints using \helpref{AddConstraint}{wxcompositeshapeaddconstraint}.
+
+After children and shapes have been added, call \helpref{Recompute}{wxcompositeshaperecompute} which
+will return TRUE is the constraints could be satisfied, FALSE otherwise. If
+constraints have been correctly and consistently specified, this call will succeed.
+
+If there is more than one child, constraints must be specified: OGL cannot calculate
+the size and position of children otherwise. Don't assume that children will simply
+move relative to the parent without the use of constraints.
+
+To specify a constraint, you need three things:
+
+\begin{enumerate}\itemsep=0pt
+\item a constraint type, such as gyCONSTRAINT\_CENTRED\_VERTICALLY;
+\item a reference shape, with respect to which other shapes are going to be positioned - the\rtfsp
+{\it constraining} shape;
+\item a list of one or more shapes to be constrained: the {\it constrained} shapes.
+\end{enumerate}
+
+The constraining shape can be either the parent of the constrained shapes, or a sibling. The
+constrained shapes must all be siblings of each other.
+
+For an exhaustive list and description of the available constraint types, see the \helpref{OGLConstraint constructor}{oglconstraintconstr}.
+Note that most constraints operate in one dimension only (vertically or horizontally), so you will
+usually need to specify constraints in pairs.
+
+You can set the spacing between constraining and constrained shapes by
+calling \helpref{OGLConstraint::SetSpacing}{oglconstraintsetspacing}.
+
+Finally, a wxCompositeShape can have {\it divisions}, which are special child shapes of class
+wxDivisionShape (not to be confused with wxDividedShape). The purpose of this is to allow
+the composite to be divided into user-adjustable regions (divisions) into which other shapes
+can be dropped dynamically, given suitable application code. Divisons allow the child
+shapes to have an identity of their own - they can be manipulated independently of their container -
+but to behave as if they are contained with the division, moving with the parent shape.
+Divisions boundaries can themselves be moved using the mouse.
+
+To create an initial division, call \helpref{wxCompositeShape::MakeContainer}{wxcompositeshapemakecontainer}.
+Make further divisions by calling \helpref{wxDivisionShape::Divide}{wxdivisionshapedivide}.

+ When a GDI object is created whilst reading in the
+ metafile, the (e.g.) createpen record is added to the
+ first free entry in the handle table. The createpen
+ record's param1 is a pointer to the actual wxPen, and
+ its param2 is the index into the gdiObjects list, which only
+ grows and never shrinks (unlike the handle table.)
+
+ When SelectObject(index) is found, the index in the file
+ refers to the position in the handle table. BUT we then
+ set param2 to be the position of the wxPen in gdiObjects,
+ i.e. to param2 of the CreatePen record, itself found in
+ the handle table.
+
+ When an object is deleted, the entry in the handletable is
+ NULLed but the gdiObjects entry is not removed (no point, and
+ allows us to create all GDI objects in advance of playing the
+ metafile).
