## Editor

The Editor is the IDE. The top level notebook represent open modules. A module is a source code file like a python module, a Python package, an wxApp file or any of the wxFrame variants (To create a module see Palette)
For each module the views supported by the module will be hosted on a second level notebook. Any actions applicable to the view like refreshing the source code or adding a module will be accessible by right clicking on the view or selecting from the 'Edit' menu. Most of these options are also available from the toolbar. Usually a default action will be triggered by double clicking on a view.

Modules

These are the supported modules:

Python module | Standard Python source code file.
Python package | Standard Python package, loads any __init__.py and shows it's directory as a package of modules as well as sub-directories containing a __init__.py file.
Text | Plain text file
wxApp | The module that hosts the wxApp object. A module list is maintained in this module. The App module controls which is the main frame of an application and currently maintains relative paths for the module list. It has a specialised Application View
wxFrame variants | Currently wrapped wxFrame type modules are wxFrame, wxDialog, wxMiniFrame, wxMDIParentFrame, wxMDIChildFrame. These modules support the Designer view for visual frame creation.

Standard Pages

These are the standard pages:

Interactive Shell | Simple Python shell.
Explorer | An Explorer for your filesystem / workspace and sys.path. It shows folders and packages in a tree on the left and all valid Boa modules in a list on the right. You may configure the list of displayed drives (MS Windows) in PrefsMSW.py CVS folders (cyan) will display their entries file with icons showing if the file has been modified since the last check in. CVS update facilities are planned. Zope browsing / document editing is also supported.

Views

These are the views on modules:

Source | Syntax highlighting source code editor. It is based on the fantastic Scintilla editor by Neil Hodgson and wrapped for wxWindows as wxStyledTextCtrl by Robin Dunn. Basic supported functionality: Auto indent/dedent Block indent/dedent Block comment/uncomment Find text Limited code completion and parameter tips Folding Limited code browsing, hold down ctrl and move mouse cursor over source code To run a Frame module without an extra derived wxApp module, select Edit->Add simple app... while on the Source View. This adds the following snippet to the end of the module:
    if __name__ == '__main__':
        app = wxPySimpleApp()
        frame = create(None)
        frame.Show(true)
        app.MainLoop()
If the module contains a Boa created frame and it's default create function, this code will let the module run on it's own.
Designer | This is the GUI bulder view for the source. The view is activated by clicking the button
Data | The DataView shows the invisible design-time objects. These are objects created from the 'Utilities' palette page.
Explore | This view show the list of classes and function defined in a module. Exploding reveals methods and events. Use this view for navigating quickly thru your code.
Hierarchy | The inheritance hierarchy of the objects in the model, color coded as follows:
Magenta | Class not defined in module
Gray | Base class
Blue | Derived class
Documentation | An html view on the doc strings in your code. The format is structured around the wxWindows look.
UML | OGL enabled view of all the classes and their inheritance relationships. This view is not complete yet.
Info | View for creation and maintenance of the comment block at the top of code identifying the author, licence etc.
ToDo | Displays a list of all comments in your code started with # XXX Handy for reviewing what needs to be done and a jumppad for quick access.
Application | View on wxApp files for maintenance of an application. Add edit and remove modules of the application thru this view. Click on the columns to sort by name, type or relative path. Find will search all the modules defined in the App and return an Application find results view. The Imports view can only be accessed from this view. When Boa was run with the -T option (trace execution) this option will built a traceback from the log file. If the stack balances out, i.e. uninterrupted execution, the stack will be empty. As the trace file may be quite big, please be patient while it is constructed. If you are not, see ErrorStack.CrashTraceLogParser to limit the max depth or max number of lines to parse.
Imports | Another OGL enabled view, this time showing the import relationships between modules of an application. i.e. who imports who.
Package | Shows all modules and other packages inside a package.

Results Views

There can be multiple instances of these views on a module, they are usually the result of an operation on the module.
The following are defined:

Application find results | List of modules in which the search text was found.
Cyclops | An HTML report of all circular references and related info. Based on module by Tim Peters
Profiler | List of profiling statistics. Sortable on the columns.
Diff modules | Difference between two modules. The current module (1) and another selected module (2) is used. Differences are noted in the margin. Plus means that a line was added in (2) and minus means that a line from (1) is no longer in (2) A block specifies an informational line that underlines the lines in the source with +'s and -'s Uses ndiff written by Tim Peters.
Compare apps | The result of the comparison of the current app and another selected by the file dialog. Double clicking on a result in the list opens a module diff of the two modules in the apps.
