I did not want to write DHTML which adapts to the browser, so IE had to be norm. In this case, I've at least gotten it to work on both browsers, even if I'm less than happy with the NS output. The HTML-generation was straightforward, except for the fact that Internet Explorer and Netscape realizes DHTML differently. I could have used redundant info, setting link info in both the line segments and the attached objects, but the maintenance of twice the information was even less appetizing. This leads to some complicated coding to establish the minimum size of objects - I had to communicate back to the container to see if any line was connected to this object, and if so, at what offset. I also wanted the connection to be free, that is, a line should be possible to link anywhere on a class object side. This can be witnessed in OnLButtonDown, OnMouseMove, and OnLButtonUp in CUMLEditor. As the links can't exist without being linked to something, and that drawing a segment, connecting it, drawing another segment, connecting it etc., would make for a very tedious process when creating diagrams, I had to go through some heavy convolutions in mouse-handling. The main problem is to keep the integrity of the links, for example, when copying and pasting. This time, the links are derived from CDiagramEntity - the basic drawing object in the editor. This is yet another implementation of links. I'm beginning to feel like I'm in a P K Dick novel. The AutoDocumenter class reference was created by AutoDocumenter - although the class diagrams where - of course - created with UMLEditor. The UMLEditor and DiagramEditor class references were created with the AutoDocumenter. Parts of the AutoDocumenter were created with UMLEditor.

AutoDocumenter will automatically create documentation for code created with UMLEditor. I've thrown in another freebie as well - AutoDocumenter. Use it, rip it apart, scrap it for parts. I have made every effort, though, to make the use of the package as simple as possible, to allow you to plug in the editor and UML away! The demoĪlso included is a MDI-app, showing the capabilities of the editor, UMLEditorDemo. The downloadable documentation contains step-by-step instructions on this, together with a complete class reference, How-to's, and a slightly updated documentation on CDiagramEditor.Īs a matter of fact, the amount of code in this project makes it impossible to write a single article on the details of the implementation - if you want to do more than plug it into your own project, you'll need to have patience and some time, and will probably be best off tracing the source code of the project. Add UI to draw objects, and then you have added an UML-editor to your application. Basically, you just add a CUMLEditor member object to either your view class or the class of the main dialog of your app.
HTML and code generation is built in, so you get it "for free", together with export to EMF (enhanced metafiles). It can be used in dialog-applications, and SDI- and MDI-applications.
The editor can be used in your own app, the same way as CDiagramEditor or CFlowchartEditor. CUMLEditor itself is an example of an advanced override of CDiagramEditor. The editor can be configured by setting colors, grid etc., and also derived from for more advanced overrides. The editor framework has the features of the parent project, CDiagramEditor, that is, unlimited zoom, undo, copying and pasting between MDI-windows, support for print and print preview, and much more. You can import class definitions from header-files. The diagrams can be loaded and saved, of course, but also exported to DHTML (not as pictures, but rather "pure" DHTML), C++-code (only the skeleton, of course), and EMF (enhanced metafiles, that can be included in - for example - Word). The connections can have the normal UML-styles, inheritance, dependency etc., although aggregation is not supported. The editor contains drawing objects for classes, interfaces, packages, notes, lines, and labels.Ĭlasses, interfaces, packages, and notes can be connected with multi-segment lines, with unlimited connection points on the objects. UML will have to be learned elsewhere, why not on CodeProject? See the Links section at the end of this article! UMLEditor As a matter of fact, parts of the UMLEditor itself is generated by the UMLEditor. It allows creation and editing of static diagrams, and can generate C++-code and HTML-pages from the diagrams. The UMLEditor package is, perhaps not surprisingly, a UML-editor.
