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.

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:

dockManager	The responsible manager (dock helper)
name	Object instance name
pixmap	An icon (for instance shown when docked centered)
parent	Parent widget
strCaption	Title of the dockwidget window (shown when toplevel)
strTabPageLabel	The 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

Destructs a dockwidget.

The possible positions where a dockwidget can dock to another dockwidget

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:

target	The dockwidget to dock to
dockPos	One of the DockPositions this is going to dock to
spliPos	The split relation (in percent, or percent*100 in high resolution) between both dockwidgets, target and this
pos	The dock position, mainly of interest for docking to the desktop (as toplevel dockwidget)
check	Only for internal use;
tabIndex	The 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.

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

Parameters:

pos	An OR'ed set of DockPositions

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

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

Parameters:

pos	An OR'ed set of DockPositions

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

Set the embedded widget.

A QLayout takes care about proper resizing, automatically.

Parameters:

w	The pointer to the dockwidget's child widget.

Get the embedded widget.

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

Set 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:

ah	A base class pointer to the dockwidget header

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.

There are reasons that it's impossible:

• It is a (tab) group.
• It is already invisible ;-)
• The parent of this is the KDockMainWindow.
• It isn't able to dock to another widget.

Returns: If it may be possible to hide this.

• It is a (tab) group.
• It is already visible ;-)
• The parent of this is the KDockMainWindow.

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

Returns: The dockmanager that is responsible for this.

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:

ttStr

A string for the tooltip on the tab.

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

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

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

Parameters:

label

The new tab page label.

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

[virtual]

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

[virtual]

Add dockwidget management actions to QWidget::show.

Returns: the parent widget of this if it inherits class KDockTabGroup

Sets the type of the dock window

Parameters:

windowType

is type of dock window

Sets the type of the dock window

Parameters:

windowType

is type of dock window

[slot]

[slot]

Toggles the visibility state of the dockwidget if it is able to be shown or to be hidden.

[slot]

Undocks this. It means it becomes a toplevel widget framed by the system window manager. A small panel at the top of this undocked widget gives the possibility to drag it into another dockwidget by mouse (docking).

[protected]

Returns: the parent widget of this if it inherits class KDockTabGroup Warning: This will be removed in KDE-3.0. Use parentDockTabGroup instead.

[protected]

Check some conditions and show or hide the dockwidget header (drag panel). The header is hidden if:

• the parent widget is the KDockMainWindow
• this is a (tab) group dockwidget
• it is not able to dock to another dockwidget

[signal]

Emits that another dockwidget is docking to this.

Parameters:

dw	the dockwidget that is docking to this
dp	the DockPosition where it wants to dock to

[signal]

Signals that the dock default position is set.

[signal]

Signals that the close button of the panel (KDockWidgetHeader) has been clicked.

[signal]

Signals that the dockback button of the panel (KDockWidgetHeader) has been clicked.

[signal]

Signals that the widget processes a close event.

[signal]

Signals that the widget is undocked now.

[protected slots slot]

Does several things here when it has noticed that the former brother widget (closest neighbor) gets lost. The former brother widget is needed for a possible dockback action, to speak with the Beatles: "To get back to where you once belonged" ;-)

[private]

Sets the caption (window title) of the given tab widget.

Parameters:

g	the group (tab) widget

[private]

Reparent to s or set this to the KDockMainWindow's view if s is that dockmainwindow. If s is O, simply move the widget.

Parameters:

s	the target widget to reparent to
p	the point to move to (if it doesn't reparent)
