This document tries to give a little overview about Quanta classes and their
|
|
interactions. The document is for Quanta+ 3.3 as of 27-05-2004.
|
|
|
|
1. src directory
|
|
-----------------
|
|
- the main classes
|
|
|
|
KSplash: the splash screen class (used only for KDE < 3.2.3). Called from the
|
|
KQApplication classes.
|
|
|
|
KQApplicationPrivate: the common class for the unique and non-unique mode
|
|
Quanta application.
|
|
|
|
KQApplication: the non-unique version of the Quanta application.
|
|
|
|
KQUniqueApplication: the unique version of the Quanta application.
|
|
|
|
QuantaApp: the main window class of Quanta. The main purpose is to handle
|
|
general user events and to process and provide general informations.
|
|
As it inherits from KMdiMainFrm it also does some window managing
|
|
jobs.
|
|
There is one global object of this type called quantaApp, but it's
|
|
recommended that you use the signal/slot mechanism instead of
|
|
calling directly the QuantaApp methods. It interacts almost with
|
|
every other class.
|
|
|
|
QuantaInit: a class used only on startup to build the user interface, load the options,
|
|
set up the signal/slot connections, etc. It has a very short life and can be
|
|
imagined as a part of QuantaApp.
|
|
|
|
QuantaDoc: an old class inherited from the pre-KMDI design of Quanta. The methods
|
|
from it most probably belong somewhere else (eg. QuantaApp). The main
|
|
tasks now are related to document opening and handling of some user
|
|
events. There is only one object of this type.
|
|
|
|
QuantaView: a QuantaView can be imagined as a visual representation of a document,
|
|
plugin, part. It's the widget on a "tab" in the user interface. Each object
|
|
may hold either a Document (real document), QuantaPlugin (a plugin) and/or
|
|
a common widget (anything, like the preview part, documentation part).
|
|
It has methods to save the document, switch between different view modes
|
|
(VPL, source) and reacts to some events, like getting the focus.
|
|
The views are managed by the ViewManager.
|
|
|
|
ViewManager: singleton object which manages the QuantaView's. It has methods to
|
|
create, remove, save views, reacts to view change, handles the
|
|
tab context menus and the D&D of tabs. Interacts with QuantaApp and
|
|
QuantaView.
|
|
|
|
Document: an editable (KTextEditor) document with advanced, Quanta specific features.
|
|
There is a 1-1 relation between a Document and QuantaView. Each view can
|
|
have one Document and each Document can have only one view. Multiple
|
|
views of the same document is not supported by Quanta at this moment.
|
|
The class has methods to manipulate the KTextEditor::Document and
|
|
KTextEditor::View via the various KTextEditor interfaces in an editor
|
|
independent mode. Main tasks are:
|
|
- react to user keypresses
|
|
- handle autocompletion (when it should appear, what should appear in the
|
|
completion box, autocompleting of child tags)
|
|
- react to changes in the document and ask for a rebuild of the node tree
|
|
- modify the closing/opening tags based on the node tree
|
|
- create temporary files of opened documents (and after each save)
|
|
- create backups of documents
|
|
- handle text and tag insertion
|
|
- handling tag modifications
|
|
- react to changes made to the document outside of Quanta
|
|
- detect the main DTD of the document. Each Document has a main DTD,
|
|
but may contain other pseudo-DTDs inside.
|
|
- provides convenience methods to work with text documents (find,
|
|
findRev, findWordRev, currentWord, text selection)
|
|
- keeps track of untitled and modified status
|
|
|
|
DTDs: stores and loads the DTEPs from disk as they are requested. Works with
|
|
DTDStruct classes (structures). Interacts with every class which works with
|
|
DTEPs. Singleton.
|
|
|
|
DCOP* classes: the DCOP interfaces of Quanta. WindowManagerIf is the general
|
|
purpose interface working mainly with views and files, implemented in the
|
|
QuantaApp class. SettingsIf is an interfaces towards various Quanta settings and
|
|
QuantaIf is an interface towards Quanta internals like selectors, used in some
|
|
of the DTEP definition files. The interfaces (except WindowManagerIf) have a separate implementation class.
|
|
|
|
|
|
2. parsers directory
|
|
---------------------
|
|
- parsing and node tree related classes (yes, QTag might not belong here)
|
|
|
|
Parser: parses a document and builds the node tree. It does a quick parsing of XML
|
|
tags, special areas are not parsed in detail, only their start and end region is
|
|
determined. For XML areas it parses also for groups and does a quick
|
|
parsing of included (XML) files as well. It has a method to parse only the
|
|
changed area of the document (rebuild) and a method to find the node from
|
|
the tree corresponding for a place in the document (nodeAt). It calls
|
|
the detailed special area parser in the background via a singleshot timer.
|
|
Interacts with the SAParser, StructureTreeView and any other class requesting
|
|
information from the node tree.
|
|
There is usually only one Parser object in the memory, but it is not a singleton
|
|
as it's used in the table editor as well.
|
|
|
|
SAParser: special area (pseudo DTEP) parser. Parses scripts, CSS, etc. Can do a quick
|
|
or detailed parsing in synchronous or asynchronous mode. The later means that
|
|
the parsing is done in small steps, using singleshot timers to call the next step, so
|
|
the user interface is not blocked while the detailed, time consuming parsing is
|
|
done. The parsing is context based. Calls the special area group parser for
|
|
every special area node. Emits signals to indicate the ending of parsing and
|
|
the need of the structure tree rebuilding.
|
|
|
|
SAGroupParser: the special area group parser called from SAParser. This can behave
|
|
asynchronously as well. Emits signals to indicate the ending of parsing and
|
|
the need of the rebuilding of the group part of the structure tree.
|
|
|
|
ParserCommon: common (static) methods used by the Parser and SAParser, and holds
|
|
parser-global data structures as well.
|
|
|
|
Node: an element of the Node tree. Each Node has a parent, child, next and previous
|
|
Node (of course they can be NULL) and a Tag. The Tag cannot be NULL.
|
|
Each node appears at least once under the visual structure tree (mainListItem),
|
|
but can appear more than once if it's part of some structure groups (listItems)
|
|
There are convenience methods which helps navigating through the node tree and
|
|
some flags noting the status of the node. See the description of the class
|
|
attributes.
|
|
|
|
Tag: a parsed tag. Each node has a tag. A tag can be a real XML tags from the
|
|
document or some other special tag noting text, empty area, structure begin,
|
|
structure end, comment, etc. XML tags are parsed and it's possible to read
|
|
the available attributes and attribute values, modify them, etc. Each tag has a
|
|
DTD associated with it, meaning that "this tag was parsed and should be
|
|
interpreted as part of this DTD", holds the position in the document, the
|
|
original text found at that position, a cleaned version of that text (without
|
|
comments), etc. A Tag is not necessary a valid tag of the DTD. <foo foo1="foo">
|
|
is a tag in any DTD.
|
|
|
|
QTag: a valid DTD tag. When the tagXML files are read, each DTDStruct will contain many
|
|
QTag objects describing the valid tags in that DTD. The QTag gives us the
|
|
possible attributes and their values, the relationship regarding other QTags and
|
|
some other status information (single, optional, etc.). A QTag can hold
|
|
information about pseudo-DTD tags, which are not real XML tags, but they can
|
|
describe methods, classes, functions, etc.
|
|
|
|
DTDParser: parses a real DTD definition file and converts to tagXML.
|
|
|
|
|
|
3. utility directory
|
|
-------------------
|
|
- helper, convenience classes; other classes not belonging anywhere else
|
|
|
|
QuantaCommon: static convenience methods, used in many places.
|
|
|
|
QConfig: holds the Quanta configuration settings.
|
|
|
|
QuantaToolBar/ToolbarTabWidget/ToolbarXMLGUI: classes needed to make the
|
|
user toolbars work.
|
|
|
|
TagAction: an extended KAction, which can be modified in Quanta. May be of three
|
|
types: Tag, Script, Text. Script actions can be executed in synchronous
|
|
(execute) or async. mode (insertTag). TagActions are usually put on the
|
|
user toolbars and under Tags menu, but they can be plugged anywhere
|
|
just like the normal KActions.
|
|
|
|
|
|
4. treeviews directory
|
|
-----------------------
|
|
- classes dealing with the different treeviews
|
|
|
|
FilesTreeView/FilesTreeBranch/FilesTreeViewItem: shows the file and directory
|
|
structure in a tree. Can show more than one tree at once. By default
|
|
it shows a tree starting with the root directory (/) and one starting with the
|
|
$HOME directory of the current user. It's possible to specify other
|
|
such top-level directories. The toplevel directories can be remote directories
|
|
as well. The class handles the events of the file and folder context menus and
|
|
communicates using signals with QuantaApp, for example to indicate that
|
|
a file must be opened.
|
|
It's an extension of the KFileTreeView.
|
|
|
|
ProjectTree* : an extension of the FilesTree* classes to show the project files in a
|
|
tree. The project files are not what are under the project directory, but
|
|
only those that are listed in the .webprj file. Communicates with QuantaApp
|
|
and the Project object via signals. It's a singleton class.
|
|
|
|
TemplatesTree*: an extension of the FilesTree* classes to show the three special
|
|
template directories (global, local and project template directory). Handles
|
|
template specific actions (insert, template settings, send in email), D&D.
|
|
It's a singleton.
|
|
|
|
ScriptTreeView: an extension of FilesTreeView class which shows the global and
|
|
local script directories, makes possible to execute or edit the scripts,
|
|
view or edit their descriptions.
|
|
|
|
StructTreeView: the visual representation of the internal node tree. Build the visual
|
|
tree from the node tree, makes possible to navigate through the document
|
|
using the tree.
|
|
|
|
StructTreeTag: an element of the structure tree. Every element has an associated Node
|
|
and the element is included in the listItems of the Node.
|
|
The problem checker is done in the constructor of the StructTreeTag element,
|
|
by verifying if the Node associated with the element holds a valid Tag for the
|
|
current DTD and the relation between the Node and the surrounding nodes
|
|
are valid in this DTD.
|
|
|
|
UploadTree*: a treeview and it's file/folder elements with a special look. There is a
|
|
column with a 3 state checkbox. In case of folders checked means that
|
|
every element under the folder is checked, un-checked means that none
|
|
of the elements under the folder are checked and grayed means that some
|
|
elements (but not all) are checked. Used in the project upload dialog, the
|
|
project folder scanning dialog and in the new project wizard.
|
|
|
|
TagAttributeTree/EnhancedTagAttributeTree/EditableTree/
|
|
DualEditableTree/TopLevelItem/Attribute*: classes used to edit the attributes of a tag.
|
|
|
|
DocTreeView/DocItem/DocFolder: the treeview and it's elements which show the
|
|
different loaded documentation files, including the project documentation.
|
|
The tree shows the documentation titles and the content is opened in a
|
|
HTML part embedded in a QuantaView or a separated toolview.
|
|
|
|
|
|
5. project directory
|
|
---------------------
|
|
- project management related classes
|
|
|
|
Project: the main project management class. Loads, stores, modifies the .webprj file.
|
|
Project related actions like project rescan, new project, project upload,
|
|
project properties, adding/removing files to the project are handled here.
|
|
It's a singleton.
|
|
|
|
ProjectNew*: classes for different stages of the new project wizard. They are
|
|
instantiated from the Project object.
|
|
|
|
ProjectUpload: class that handles uploading of project files. It has also a special mode
|
|
when the UI is minimized and in this mode the class can be used to modify
|
|
the upload profiles.
|
|
|
|
RescanPrj: class that handles rescanning of the project directory and marking the
|
|
files that are under the directory but not in the .webprj file. It does not show
|
|
or mark the files that are excluded from the project in the project options.
|
|
|
|
ProjectURL: an extended KURL with some status informations including description,
|
|
upload status and a note if the URL is a document-base folder or not.
|
|
Used inside Project and the other classes dealing with the project files (ProjectUpload, ProjectTreeView)
|
|
|
|
|
|
6. plugins directory
|
|
---------------------
|
|
- (mainly) classes related to the plugin system
|
|
|
|
QuantaPlugin: manages a configured Quanta plugin (a KPart). Takes care of loading and
|
|
unloading of the part, embedding it in a widget and calling the part's
|
|
openURL method with the configured argument. Special plugins that
|
|
needs to have a more detailed communication with Quanta can have
|
|
a plugin class inherited from QuantaPlugin.
|
|
|
|
QuantaPluginInterface: the interface between QuantaApp and the QuantaPlugins. Reads
|
|
the plugins, returns pointers to them on request, validates them, etc.
|
|
|
|
QuantaPluginEditor and QuantaPluginConfig: classes which helps configuring the plugins.
|
|
|
|
SpellChecker: Quanta specific spellchecker. Not a real QuantaPlugin and most probably
|
|
it belongs to the utility directory.
|
|
|
|
|
|
7. parts directory
|
|
------------------
|
|
- KParts used inside Quanta.
|
|
|
|
WHTMLPart: simple TDEHTML based class which can display HTML pages. Used in preview
|
|
and documentation.
|
|
|
|
kafka directory: VPL related classes
|
|
|
|
|
|
8. messages directory
|
|
------------------------
|
|
- messaging system
|
|
|
|
MessageOutput/MessageItem: widget to show messages from external applications or
|
|
from Quanta. Used to display the result of actions, but used by the
|
|
Problem reporter as well. It has a methods to find the line and column
|
|
number inside a message and clicking on a text containing the line and
|
|
column moves the cursor in the editor to that position.
|
|
|
|
|
|
9. dialogs directory
|
|
---------------------
|
|
- some dialog implementations used in Quanta. The settings subdirectory contains the
|
|
widget implementations for the different Quanta setting pages, the tagdialog directory
|
|
contains classes dealing with the tagXML dialogs.
|
|
|
|
ActionConfigDialog: makes TagAction configuration possible. Displays all possible
|
|
actions (not just TagActions) in a tree, all loaded user toolbars with
|
|
the actions on them. TagActions can be created, deleted, modified and
|
|
plugged/unplugged in a user toolbar.
|
|
|
|
CopyTo: class which is used in many places to do asynchronous file copy. It signals
|
|
when the file copy is done and the object can be deleted. Mainly used
|
|
inside the Project* classes to add files to the project.
|
|
|
|
DirtyDlg: dialog offering some possibilities for the user when a document was changed
|
|
outside of Quanta. In case of comparing the files it launches Kompare, waits
|
|
until it finishes and returns afterwards, this way blocking Quanta while Kompare
|
|
is running.
|
|
|
|
FileCombo: widget class offering a combobox and a button to select files. Used in the
|
|
Tagxml class.
|
|
|
|
SpecialCharDialog: a dialog which offers the user a list of special characters.
|
|
|
|
AbbreviationDlg: handles the code abbreviations (adding/removing/editing them)
|
|
|
|
FileMasks: a badly named class. Currently takes care of editing the environment settings.
|
|
|
|
ParserOptions: make possible to finetune the parser and the structure tree behavior.
|
|
|
|
PreviewOptions: another not so well named class, as currently it makes possible to
|
|
configure the UI look and behavior. Between others it offers possibility to
|
|
change the preview and documentation location, the tab and toolview
|
|
behavior, etc.
|
|
|
|
tagdialogs directory: classes and widgets used to build a dialog from a tagXML file, which
|
|
makes possible to edit a tag in a document. Based on a Tag and the
|
|
corresponding QTag.
|
|
|
|
|
|
10. components directory

|
|
(document context menu, treeview context menus) using cvsservice from
|
|
Cervisia.
|
|
|
|
debugger directory: classes providing interface towards different debuggers, including
|
|
