9 * provide end users with a common look and feel
10 * reduce memory footprint through sharing code
11 * reduce possible bugs through reusing tested code

2==================================================================
3March 2003 - Initial checkin into the Opie CVS:
4==================================================================
5
6So, this is what I have been working on over the last months.
7It's a part of what I think could migrate into our next generation
8opielibs.
9Of course this won't happen after we released Opie 1.0 and switched
10to Qt3-Embedded and gcc 3.
11
12Right now, there is content only in opiecore, opienet and opieui.
13A good part of code has been adapted from the kdelibs, which overall
14are pretty good however in details of heterogenous quality. I'm also
15not sure if all I ported should be kept, e.g. the pixmapeffect stuff
16seems unnecesary to me. However, we should not forget that Opie will
17make its debut on more powerful devices with greater display
18resolution, e.g. the Sharp C700, so we shouldn't limit ourselves in
19what should go into the libraries.
20
21Generally spoken, a lot of things are still very rough and messy,
22but I will keep improving this. Some details about what is usable
23and what is not follows:
24(everything compiles of course, otherwise I wouldn't have checked in :-)
25
26[-----------]
27[ opiecore ]
28[-----------]
29oapplication, oconfig, oglobal seem to be usable yet, oglobalsettings
30is still very messy and should be revised. A lot more thinking about how
31we should keep opie preferences, especially when moving to multi-user, has to be made.
32This will affect what goes into oglobalsettings and what configuration data
33format we will use. If we switch to Qt3 we will have to decide if we stay
34with OConfig deriving from Config or rewrite it using QSettings.
35
36[-----------]
37[ opiedb ]
38[-----------]
39There is nothing here yet. The sqlite stuff should be here.
40
41[-----------]
42[ opienet ]
43[-----------]
44onetwork*, omonitoring* and the opacket stuff are pretty usable and not
45very far from being complete. documentation for these will come...
46Over the next days, opie-wellenreiter, opie-wirelessapplet and the
47forthcoming new opie-networkapplet will be using the
48new network classes.
49I think all the other network libraries spread throught opie, e.g.
50libbend, libmail, ftplib should be revised and become part of
51opienet eventually.
52
53[-----------]
54[ opiepim ]
55[-----------]
56Nothing here yet. The stuff currently in libopie/pim should be here.
57
58[-----------]
59[ opieui ]
60[-----------]
61Pretty messy yet, but some things are usable. Unfortunately, the UI
62stuff is very hard to backport to Qt2, so some things only work
63if compiled against Qt3, especially all the popupcompletion stuff.
64OListView however works nice and is currently used in opie-wellenreiter.

105 *
106 * Careful programmers always set the group of a
107 * @ref OConfig object to the group they want to read from
108 * and set it back to the old one of afterwards. This is usually
109 * written as:
110 * <pre>
111 *
112 * QString oldgroup config()->group();
113 * config()->setGroup( "TheGroupThatIWant" );
114 * ...
115 * config()->writeEntry( "Blah", "Blubb" );
116 *
117 * config()->setGroup( oldgroup );
118 * </pre>
119 *
120 * In order to facilitate this task, you can use
121 * OConfigGroupSaver. Simply construct such an object ON THE STACK
122 * when you want to switch to a new group. Then, when the object goes
123 * out of scope, the group will automatically be restored. If you
124 * want to use several different groups within a function or method,
125 * you can still use OConfigGroupSaver: Simply enclose all work with
126 * one group (including the creation of the OConfigGroupSaver object)
127 * in one block.

69 * odbgstream is a text stream that allows you to print debug messages.
70 * Using the overloaded "<<" operator you can send messages. Usually
71 * you do not create the odbgstream yourself, but use @ref odDebug() (odebug)
72 * @ref odWarning() (owarn), @ref odError() (oerr) or @ref odFatal (ofatal) to obtain one.
73 *
74 * Example:
75 * <pre>
76 * int i = 5;
77 * odebug << "The value of i is " << i << oendl;
78 * </pre>

66/**
67 * This class offers easy use of "auto-completion", "manual-completion" or
68 * "shell completion" on QString objects. A common use is completing filenames
69 * or URLs (see @ref OURLCompletion()).
70 * But it is not limited to URL-completion -- everything should be completable!
71 * The user should be able to complete email-addresses, telephone-numbers,
72 * commands, SQL queries, ...
73 * Every time your program knows what the user can type into an edit-field, you
74 * should offer completion. With OCompletion, this is very easy, and if you are
75 * using a line edit widget (@ref OLineEdit), it is even more easy.
76 * Basically, you tell a OCompletion object what strings should be completable
77 * and whenever completion should be invoked, you call @ref makeCompletion().
78 * OLineEdit and (an editable) OComboBox even do this automatically for you.
79 *
80 * OCompletion offers the completed string via the signal @ref match() and
81 * all matching strings (when the result is ambiguous) via the method
82 * @ref allMatches().
83 *
84 * Notice: auto-completion, shell completion and manual completion work
85 * slightly differently:
86 *
87 * @li auto-completion always returns a complete item as match.
88 * When more than one matching items are available, it will deliver just
89 * the first (depending on sorting order) item. Iterating over all matches
90 * is possible via @ref nextMatch() and @ref previousMatch().
91 *
92 * @li popup-completion works in the same way, the only difference being that
93 * the completed items are not put into the edit-widget, but into a
94 * separate popup-box.
95 *
96 * @li manual completion works the same way as auto-completion, the
97 * subtle difference is, that it isn't invoked automatically while the user
98 * is typing, but only when the user presses a special key. The difference
99 * of manual and auto-completion is therefore only visible in UI classes,
100 * OCompletion needs to know whether to deliver partial matches
101 * (shell completion) or whole matches (auto/manual completion), therefore
102 * @ref OGlobalSettings::CompletionMan and
103 * @ref OGlobalSettings::CompletionAuto have the exact same effect in
104 * OCompletion.
105 *
106 * @li shell completion works like how shells complete filenames:
107 * when multiple matches are available, the longest possible string of all
108 * matches is returned (i.e. only a partial item).
109 * Iterating over all matching items (complete, not partial) is possible
110 * via @ref nextMatch() and @ref previousMatch().
111 *
112 * You don't have to worry much about that though, OCompletion handles
113 * that for you, according to the setting @ref setCompletionMode().
114 * The default setting is globally configured by the user and read
115 * from @ref OGlobalSettings::completionMode().
116 *
117 * A short example:
118 * <pre>
119 * OCompletion completion;
120 * completion.setOrder( OCompletion::Sorted );
121 * completion.addItem( "pfeiffer@kde.org" );
122 * completion.addItem( "coolo@kde.org" );
123 * completion.addItem( "carpdjih@sp.zrz.tu-berlin.de" );
124 * completion.addItem( "carp@cs.tu-berlin.de" );
125 *
126 * cout << completion.makeCompletion( "ca" ).latin1() << endl;
127 * </pre>
128 * In shell-completion-mode, this will be "carp"; in auto-completion-
129 * mode it will be "carp@cs.tu-berlin.de", as that is alphabetically
130 * smaller.
131 * If setOrder was set to Insertion, "carpdjih@sp.zrz.tu-berlin.de"
132 * would be completed in auto-completion-mode, as that was inserted before
133 * "carp@cs.tu-berlin.de".
134 *
135 * You can dynamically update the completable items by removing and adding them
136 * whenever you want.
137 * For advanced usage, you could even use multiple OCompletion objects. E.g.
138 * imagine an editor like kwrite with multiple open files. You could store
139 * items of each file in a different OCompletion object, so that you know (and
140 * tell the user) where a completion comes from.
141 *
142 * Note: OCompletion does not work with strings that contain 0x0 characters
143 * (unicode nul), as this is used internally as a delimiter.
144 *
145 * You may inherit from OCompletion and override @ref makeCompletion() in
146 * special cases (like reading directories/urls and then supplying the
147 * contents to OCompletion, as OURLCompletion does), but generally, this is
148 * not necessary.
149 *

53/**
54 * A combined button, line-edit and a popup list widget.
55 *
56 * @sect Detail
57 *
58 * This widget inherits from @ref QComboBox and implements
59 * the following additional functionalities: a completion
60 * object that provides both automatic and manual text
61 * completion as well as text rotation features, configurable
62 * key-bindings to activate these features, and a popup-menu
63 * item that can be used to allow the user to set text completion
64 * modes on the fly based on their preference.
65 *
66 * To support these new features OComboBox also emits a few
67 * more additional signals as well. The main ones are the
68 * @ref completion( const QString& ) and @ref textRotation( KeyBindingType )
69 * signals. The completion signal is intended to be connected to a slot
70 * that will assist the user in filling out the remaining text while
71 * the rotation signals is intended to be used to traverse through all
72 * possible matches whenever text completion results in multiple matches.
73 * The @ref returnPressed() and @ref returnPressed( const QString& )
74 * signal is emitted when the user presses the Enter/Return key.
75 *
76 * This widget by default creates a completion object when you invoke
77 * the @ref completionObject( bool ) member function for the first time
78 * or use @ref setCompletionObject( OCompletion*, bool ) to assign your
79 * own completion object. Additionally, to make this widget more functional,
80 * OComboBox will by default handle the text rotation and completion
81 * events internally whenever a completion object is created through either
82 * one of the methods mentioned above. If you do not need this functionality,
83 * simply use @ref OCompletionBase::setHandleSignals( bool ) or alternatively
84 * set the boolean parameter in the above methods to FALSE.
85 *
86 * The default key-bindings for completion and rotation is determined
87 * from the global settings in @ref OStdAccel. These values, however,
88 * can be overriden locally by invoking @ref OCompletionBase::setKeyBinding().
89 * The values can easily be reverted back to the default setting, by simply
90 * calling @ref useGlobalSettings(). An alternate method would be to default
91 * individual key-bindings by usning @ref setKeyBinding() with the default
92 * second argument.
93 *
94 * Note that if this widget is not editable ( i.e. select-only ), then only
95 * one completion mode, @p CompletionAuto, will work. All the other modes are
96 * simply ignored. The @p CompletionAuto mode in this case allows you to
97 * automatically select an item from the list by trying to match the pressed
98 * keycode with the first letter of the enteries in the combo box.
99 *
100 * @sect Useage
101 *
102 * To enable the basic completion feature:
103 *
104 * <pre>
105 * OComboBox *combo = new OComboBox( true, this, "mywidget" );
106 * OCompletion *comp = combo->completionObject();
107 * // Connect to the return pressed signal - optional
108 * connect(combo,SIGNAL(returnPressed(const QString&)),comp,SLOT(addItem(const QString&));
109 * </pre>
110 *
111 * To use your own completion object:
112 *
113 * <pre>
114 * OComboBox *combo = new OComboBox( this,"mywidget" );
115 * OURLCompletion *comp = new OURLCompletion();
116 * combo->setCompletionObject( comp );
117 * // Connect to the return pressed signal - optional
118 * connect(combo,SIGNAL(returnPressed(const QString&)),comp,SLOT(addItem(const QString&));
119 * </pre>
120 *
121 * Note that you have to either delete the allocated completion object
122 * when you don't need it anymore, or call
123 * setAutoDeleteCompletionObject( true );
124 *
125 * Miscellaneous function calls:
126 *
127 * <pre>
128 * // Tell the widget not to handle completion and rotation
129 * combo->setHandleSignals( false );
130 * // Set your own completion key for manual completions.
131 * combo->setKeyBinding( OCompletionBase::TextCompletion, Qt::End );
132 * // Hide the context (popup) menu
133 * combo->setContextMenuEnabled( false );
134 * // Temporarly disable signal emition
135 * combo->disableSignals();
136 * // Default the all key-bindings to their system-wide settings.
137 * combo->useGlobalKeyBindings();
138 * </pre>
139 *
140 * @short An enhanced combo box.

53/**
54 * Provides a number of ready to use layouts (faces). It is used
55 * as an internal widget in @ref KDialogBase, but can also used as a
56 * widget of its own.
57 *
58 * It provides TreeList, IconList, Tabbed, Plain and Swallow layouts.
59 *
60 * The TreeList face provides a list in the left area and pages in the
61 * right. The area are separated by a movable splitter. The style is somewhat
62 * similar to the layout in the Control Center. A page is raised by
63 * selecting the corresponding tree list item.
64 *
65 * The IconList face provides an icon list in the left area and pages in the
66 * right. For each entry the Icon is on top with the text below. The style
67 * is somewhat similar to the layout of the Eudora configuation dialog box.
68 * A page is raised by selecting the corresponding icon list item. The
69 * preferred icon size is 32x32 pixels.
70 *
71 * The Tabbed face is a common tabbed widget. The procedure for creating a
72 * page is similar for creating a TreeList. This has the advantage that if
73 * your widget contain too many pages it is trivial to convert it into a
74 * TreeList. Just change the face in the KJanusWidget constructor to
75 * KJanusWidget::TreeList and you have a tree list layout instead.
76 *
77 * The Plain face provides an empty widget (QFrame) where you can place your
78 * widgets. The KJanusWidget makes no assumptions regarding the contents so
79 * you are free to add whatever you want.
80 *
81 * The Swallow face is provided in order to simplify the usage of existing
82 * widgets and to allow changing the visible widget. You specify the widget
83 * to be displayed by @ref #setSwallowedWidget(). Your widget will be
84 * reparented inside the widget. You can specify a Null (0) widget. A empty
85 * space is then displayed.
86 *
87 * For all modes it is important that you specify the @ref QWidget::minimumSize()
88 * on the page, plain widget or the swallowed widget. If you use a QLayout
89 * on the page, plain widget or the swallowed widget this will be taken care
90 * of automatically. The size is used when the KJanusWidget determines its
91 * own minimum size. You get the minimum size by using the
92 * @ref #minimumSizeHint() or @ref #sizeHint() methods.
93 *
94 * Pages that have been added in TreeList, IconList or Tabbed mode can be
95 * removed by simply deleting the page.
96 *

51 * An enhanced QLineEdit widget for inputting text.
52 *
53 * @sect Detail
54 *
55 * This widget inherits from @ref QLineEdit and implements the following
56 * additional functionalities: q completion object that provides both
57 * automatic and manual text completion as well as multiple match iteration
58 * features, configurable key-bindings to activate these features and a
59 * popup-menu item that can be used to allow the user to set text completion
60 * modes on the fly based on their preference.
61 *
62 * To support these new features OLineEdit also emits a few more
63 * additional signals. These are: @ref completion( const QString& ),
64 * textRotation( KeyBindingType ), and @ref returnPressed( const QString& ).
65 * The completion signal can be connected to a slot that will assist the
66 * user in filling out the remaining text. The text rotation signal is
67 * intended to be used to iterate through the list of all possible matches
68 * whenever there is more than one match for the entered text. The
69 * @p returnPressed( const QString& ) signals are the same as QLineEdit's
70 * except it provides the current text in the widget as its argument whenever
71 * appropriate.
72 *
73 * This widget by default creates a completion object when you invoke
74 * the @ref completionObject( bool ) member function for the first time or
75 * use @ref setCompletionObject( OCompletion*, bool ) to assign your own
76 * completion object. Additionally, to make this widget more functional,
77 * OLineEdit will by default handle the text rotation and completion
78 * events internally when a completion object is created through either one
79 * of the methods mentioned above. If you do not need this functionality,
80 * simply use @ref OCompletionBase::setHandleSignals( bool ) or set the
81 * boolean parameter in the above functions to FALSE.
82 *
83 * The default key-bindings for completion and rotation is determined
84 * from the global settings in @ref OStdAccel. These values, however,
85 * can be overriden locally by invoking @ref OCompletionBase::setKeyBinding().
86 * The values can easily be reverted back to the default setting, by simply
87 * calling @ref useGlobalSettings(). An alternate method would be to default
88 * individual key-bindings by usning @ref setKeyBinding() with the default
89 * second argument.
90 *
91 * NOTE that if the @p EchoMode for this widget is set to something other
92 * than @p QLineEdit::Normal, the completion mode will always be defaulted
93 * to @ref PGlobalSettings::CompletionNone. This is done purposefully to guard
94 * against protected entries such as passwords being cached in @ref OCompletion's
95 * list. Hence, if the @p EchoMode is not @ref QLineEdit::Normal, the completion
96 * mode is automatically disabled.
97 *
98 * @sect Useage
99 *
100 * To enable the basic completion feature :
101 *
102 * <pre>
103 * OLineEdit *edit = new OLineEdit( this, "mywidget" );
104 * OCompletion *comp = edit->completionObject();
105 * // Fill the completion object with a list of possible matches
106 * QStringList list;
107 * list << "mickeyl@handhelds.org" << "mickey@tm.informatik.uni-frankfurt.de>" << "mickey@Vanille.de";
108 * comp->setItems( list );
109 * // Connect to the return pressed signal (optional)
110 * connect(edit,SIGNAL(returnPressed(const QString&)),comp,SLOT(addItem(const QString&));
111 * </pre>
112 *
113 * To use a customized completion objects or your
114 * own completion object :
115 *
116 * <pre>
117 * OLineEdit *edit = new OLineEdit( this,"mywidget" );
118 * KURLCompletion *comp = new KURLCompletion();
119 * edit->setCompletionObject( comp );
120 * // Connect to the return pressed signal - optional
121 * connect(edit,SIGNAL(returnPressed(const QString&)),comp,SLOT(addItem(const QString&));
122 * </pre>
123 *
124 * Note that you have to either delete the allocated completion object
125 * when you don't need it anymore, or call
126 * setAutoDeleteCompletionObject( true );
127 *
128 * @sect Miscellaneous function calls :
129 *
130 * <pre>
131 * // Tell the widget not to handle completion and
132 * // iteration internally.
133 * edit->setHandleSignals( false );
134 * // Set your own completion key for manual completions.
135 * edit->setKeyBinding( OCompletionBase::TextCompletion, Qt::End );
136 * // Hide the context (popup) menu
137 * edit->setContextMenuEnabled( false );
138 * // Temporarly disable signal emitions
139 * // (both completion & iteration signals)
140 * edit->disableSignals();
141 * // Default the key-bindings to system settings.
142 * edit->useGlobalKeyBindings();
143 * </pre>
