## Detailed Description

A special kind of KMainWindow that is able to have dockwidget child widgets (and member of the dockwidget class set).

The main widget should be a KDockWidget where other KDockWidget can be docked to the left, right, top, bottom or to the middle. Note: dock to the middle means to drop on a dockwidget and to unite them to a new widget, a tab control.

Furthermore, the KDockMainWindow has got the KDockManager and some data about the dock states.

If you've got some dockwidgets, you can dock them to the dockmainwindow to initialize a start scene: Here an example:

     DockApplication::DockApplication( const char* name) : KDockMainWindow( name)
     {
       ...
       KDockWidget* mainDock;
       mainDock = createDockWidget( "Falk's MainDockWidget", mainPixmap, 0L, "main_dock_widget");
       AnyContentsWidget* cw = new AnyContentsWidget( mainDock);
       mainDock->setWidget( cw);
       // allow others to dock to the 4 sides
       mainDock->setDockSite(KDockWidget::DockCorner);
       // forbit docking abilities of mainDock itself
       mainDock->setEnableDocking(KDockWidget::DockNone);
       setView( mainDock); // central widget in a KDE mainwindow
       setMainDockWidget( mainDock); // master dockwidget
       ...
       KDockWidget* dockLeft;
       dockLeft = createDockWidget( "Intially left one", anyOtherPixmap, 0L, i18n("The left dockwidget"));
       AnotherWidget* aw = new AnotherWidget( dockLeft);
       dockLeft->setWidget( aw);
       dockLeft->manualDock( mainDock,              // dock target
                             KDockWidget::DockLeft, // dock site
                             20 );                  // relation target/this (in percent)
       ...

Docking is fully dynamical at runtime. That means you can always move dockwidgets via drag and drop.

And last but not least you can use the popupmenu for showing or hiding any controlled dockwidget of this class and insert it to your main menu bar or anywhere else.

## Constructor & Destructor Documentation

KDockMainWindow::KDockMainWindow | ( | QWidget * | parent = 0L,
|  | const char * | name = 0L,
|  | WFlags | f = WType_TopLevel|WDestructiveClose
| ) |

Constructs a dockmainwindow.

It calls its base class constructor and does additional things concerning to the dock stuff:

- information about the dock state of this' children gets initialized
- a dockmanager is created...
- ...and gets initialized
- the main dockwidget is set to 0

Parameters:

  name | object name

Definition at line 96 of file kdockwidget.cpp.

References dockManager, QString::latin1(), mainDockWidget, and KStdAccel::name().

KDockMainWindow::~KDockMainWindow | ( |  | ) | `[virtual]`

| Destructs a dockmainwindow. Definition at line 104 of file kdockwidget.cpp. References dockManager.

## Member Function Documentation

KDockManager* KDockMainWindow::manager | ( |  | ) | const`[inline]`

Returns the dockmanager of this.

(see KDockManager)

Returns:
  pointer to the wanted dockmanager

Definition at line 1238 of file kdockwidget.h.

void KDockMainWindow::setMainDockWidget | ( | KDockWidget * |  | ) |

Sets a new main dockwidget.

Additionally, the toolbar is re-initialized.

Parameters:

  _ | dockwidget that become the new main dockwidget

Definition at line 109 of file kdockwidget.cpp.

References dockManager, mainDockWidget, and KDockManager::setMainDockWidget2().

Referenced by KDockManager::readConfig().

KDockWidget* KDockMainWindow::getMainDockWidget | ( |  | ) | const`[inline]`

Returns the main dockwidget.

Returns:
  pointer to the main dockwidget

Definition at line 1253 of file kdockwidget.h.

Referenced by KDockManager::writeConfig().

KDockWidget * KDockMainWindow::createDockWidget | ( | const QString & | name,
|  | const QPixmap & | pixmap,
|  | QWidget * | parent = 0L,
|  | const QString & | strCaption = QString::null,
|  | const QString & | strTabPageLabel = QString::fromLatin1("")
| ) |

This is one of the most important methods! The KDockMainWindow creates a new dockwidget object here that usually should encapsulate the user's widget.

The new dockwidget is automatically taken under control by the dockmanager of the dockmainwindow.

Parameters:

  name | QObject name (default dockwidget caption)
  pixmap | window icon (for instance shown when docked as tabwidget entry)
  parent | parent widget for the new dockwidget
  strCaption | window title (shown when toplevel)
  strTabPageLabel | title of the tab page (visible when in tab page mode), if it is "", only the icon will be shown; if it is 0L, the label is set to strCaption

Returns:
  a pointer to the new created dockwidget

Definition at line 129 of file kdockwidget.cpp.

References dockManager, QString::latin1(), and KStdAccel::name().

void KDockMainWindow::writeDockConfig | ( | QDomElement & | base | ) |

void KDockMainWindow::readDockConfig | ( | QDomElement & | base | ) |

References dockManager, and KDockManager::readConfig().

void KDockMainWindow::activateDock | ( |  | ) | `[inline]`

Additionally, if the main dockwidget is not a QDialog, it will be shown. Definition at line 1302 of file kdockwidget.h. References KDockManager::activate().

QPopupMenu* KDockMainWindow::dockHideShowMenu | ( |  | ) | const`[inline]`

Returns a popup menu that contains entries for all controlled dockwidgets making hiding and showing them possible.

Returns:
