Detailed Description

Floatable widget that can be dragged around with the mouse and encapsulate the actual widgets (and member of the dockwidget class set).

You just grip the double-lined panel, tear it off its parent widget, drag it somewhere and let it loose. Depending on the position where you leave it, the dockwidget becomes a toplevel window on the desktop (floating mode) or docks to a new widget (dock mode). Note: A KDockWidget can only be docked to a KDockWidget.

If you want to use this kind of widget, your main application window has to be a KDockMainWindow. That is because it has got several additional dock management features, for instance a KDockManager that has an overview over all dockwidgets and and a dockmovemanager (internal class) that handles the dock process.

Usually you create an KDockWidget that covers the actual widget in this way:


 ...
 KDockMainWindow* mainWidget;
 ...
 KDockWidget* dock = 0L;
 dock = mainWidget->createDockWidget( "Any window caption", nicePixmap, 0L, i18n("window caption")); // 0L==no parent
 QWidget* actualWidget = new QWidget( dock);
 dock->setWidget( actualWidget); // embed it
 dock->setToolTipString(i18n("That's me")); // available when appearing as tab page
 ...

See KDockMainWindow how a dockwidget is docked in.

 KDockWidget ( KDockManager* dockManager, const char* name, const QPixmap &pixmap, QWidget* parent = 0L, const QString& strCaption = 0L, const QString& strTabPageLabel = " ", WFlags f = 0)

KDockWidget

Construct a dockwidget.

Initially, docking to another and docking to this is allowed for every DockPosition. It is supposed to be no (tab) group. It will taken under control of its dockmanager.

Parameters:
dockManagerThe responsible manager (dock helper)
nameObject instance name
pixmapAn icon (for instance shown when docked centered)
parentParent widget
strCaptionTitle of the dockwidget window (shown when toplevel)
strTabPageLabelThe title of the tab page (shown when in tab page mode), if it is "", only the icon will be shown, if it is 0L, the label is set to strCaption

 ~KDockWidget ()

~KDockWidget

[virtual]

Destructs a dockwidget.

enum DockPosition { DockNone = 0, DockTop = 0x0001, DockLeft = 0x0002, DockRight = 0x0004, DockBottom = 0x0008, DockCenter = 0x0010, DockDesktop= 0x0020, DockCorner = DockTop | DockLeft | DockRight | DockBottom, DockFullSite = DockCorner | DockCenter, DockFullDocking = DockFullSite | DockDesktop }

DockPosition

The possible positions where a dockwidget can dock to another dockwidget

KDockWidget*  manualDock ( KDockWidget* target, DockPosition dockPos, int spliPos = 50, QPoint pos = QPoint(0,0), bool check = false, int tabIndex = -1)

manualDock

This is a key method of this class! Use it to dock dockwidgets to another dockwidget at the right position within its KDockMainWindow or a toplevel dockwidget.

If the target is null, it will become a toplevel dockwidget at position pos; Note: Docking to another dockwidget means exactly: A new parent dockwidget will be created, that replaces the target dockwidget and contains another single helper widget (tab widget or panner) which contains both dockwidgets, this and the target dockwidget. So consider parent<->child relationships change completely during such actions.

Parameters:
targetThe dockwidget to dock to
dockPosOne of the DockPositions this is going to dock to
spliPosThe split relation (in percent, or percent*100 in high resolution) between both dockwidgets, target and this
posThe dock position, mainly of interest for docking to the desktop (as toplevel dockwidget)
checkOnly for internal use;
tabIndexThe position index of the tab widget (when in tab page mode), -1 (default) means append

Returns: result The group dockwidget that replaces the target dockwidget and will be grandparent of target and this.

void  setEnableDocking ( int pos )

setEnableDocking

Specify where it is either possible or impossible for this to dock to another dockwidget.

Parameters:
posAn OR'ed set of DockPositions

int  enableDocking ()

enableDocking

[const]

Returns: Where it is either possible or impossible for this to dock to another dockwidget (an OR'ed set of DockPositions).

void  setDockSite ( int pos )

setDockSite

Specify where it is either possible or impossible for another dockwidget to dock to this.

Parameters:
posAn OR'ed set of DockPositions

int  dockSite ()

dockSite

[const]

Returns: There it is either possible or impossible for another dockwidget to dock to this (an OR'ed set of DockPositions).

void  setWidget ( QWidget* w)

setWidget

Sets the embedded widget.

A QLayout takes care about proper resizing, automatically.

Parameters:
wThe pointer to the dockwidget's child widget.

QWidget*  getWidget ()

getWidget

[const]

Get the embedded widget.

Returns: The pointer to the dockwidget's child widget, 0L if there's no such child.

void  setHeader ( KDockWidgetAbstractHeader* ah)

setHeader

Sets the header of this dockwidget.

A QLayout takes care about proper resizing, automatically. The header contains the drag panel, the close button and the stay button.

Parameters:
ahA base class pointer to the dockwidget header

void  makeDockVisible ()

makeDockVisible

Normally it simply shows the dockwidget.

But additionally, if it is docked to a tab widget (DockCenter), it is set as the active (visible) tab page.

bool  mayBeHide ()

mayBeHide

[const]

There are reasons that it's impossible:

Returns: If it may be possible to hide this.

bool  mayBeShow ()

mayBeShow

[const]

Returns: If it may be possible to show this. There are reasons that it's impossible:

KDockManager*  dockManager ()

dockManager

[const]

Returns: The dockmanager that is responsible for this.

void  setToolTipString (const QString& ttStr)

setToolTipString

Stores a string for a tooltip.

That tooltip string has only a meaning when this dockwidget is shown as tab page. In this case the tooltip is shown when one holds the mouse cursor on the tab page header. Such tooltip will for instance be useful, if you use only icons there. Note: Setting an empty string switches the tooltip off.

Parameters:
ttStrA string for the tooltip on the tab.

const QString&  toolTipString ()

toolTipString

[const]

Returns: The tooltip string being shown on the appropriate tab page header when in dock-centered mode.

bool  isDockBackPossible ()

isDockBackPossible

[const]

Returns: result true, if a dockback is possible, otherwise false.

void  setTabPageLabel ( const QString& label)

setTabPageLabel

Sets a string that is used for the label of the tab page when in tab page mode

Parameters:
labelThe new tab page label.

const QString&  tabPageLabel ()

tabPageLabel

[const]

Returns: A string that is used for the label of the tab page when in tab page mode.

bool  event ( QEvent * )

event

[virtual]

Catches and processes some QWidget events that are interesting for dockwidgets.

void  show ()

show

[virtual]

Add dockwidget management actions to QWidget::show.

KDockTabGroup*  parentDockTabGroup ()

parentDockTabGroup

void  updateHeader ()

updateHeader

[protected]

Checks some conditions and shows or hides the dockwidget header (drag panel). The header is hidden if:
