Detailed Description

Base class for parts.

A "part" is a GUI component, featuring:

About the widget Note that KParts::Part does not inherit QWidget. This is due to the fact that the "visual representation" will probably not be a mere QWidget, but an elaborate one. That's why when implementing your KParts::Part (or derived) you should call KParts::Part::setWidget() in your constructor.

About the GUI elements Those elements trigger actions, defined by the part (action()). The layout of the actions in the GUI is defined by an XML file (setXMLFile()).

See also ReadOnlyPart and ReadWritePart, which define the framework for a "viewer" part and for an "editor"-like part. Use Part directly only if your part doesn't fit into those.

Constructor & Destructor Documentation

Part::Part QObject   parent = 0,
const char *    name = 0
 

Constructor.

Parameters:
parent  Parent object of the part.
name  QT-internal name of the part.

Definition at line 130 of file part.cpp.

Part::~Part   [virtual]
 

Destructor.

Definition at line 139 of file part.cpp.

References QObject::destroyed(), QObject::disconnect(), and KParts::PartManager::removePart().


Member Function Documentation

void Part::embed QWidget   parentWidget [virtual]
 

Embed this part into a host widget.

You don't need to do this if you created the widget with the correct parent widget - this is just a QWidget::reparent(). Note that the Part is still the holder of the QWidget, meaning that if you delete the Part, then the widget gets destroyed as well, and vice-versa. This method is not recommended since creating the widget with the correct parent is simpler anyway.

Definition at line 162 of file part.cpp.

References QWidget::reparent(), and widget().

QWidget * Part::widget   [virtual]
 

Returns:
The widget defined by this part, set by setWidget().

Definition at line 168 of file part.cpp.

Referenced by KParts::PartManager::addPart(), KParts::ReadWritePart::closeURL(), embed(), KParts::PartManager::setActivePart(), and KParts::PartManager::setSelectedPart().

PartManager * Part::manager  
 

Returns the part manager handling this part, if any (0L otherwise).

Definition at line 178 of file part.cpp.

void Part::setSelectable bool    selectable [virtual]
 

Parameters:
selectable  Indicates whether the part is selectable or not.

Definition at line 208 of file part.cpp.

bool Part::isSelectable  
 

Returns whether the part is selectable or not.

Definition at line 213 of file part.cpp.

void KParts::Part::setWindowCaption const QString   caption [signal]
 

Emitted by the part, to set the caption of the window(s) hosting this part.

Referenced by KParts::ReadOnlyPart::guiActivateEvent(), KParts::ReadOnlyPart::openURL(), and KParts::ReadWritePart::saveAs().

void KParts::Part::setStatusBarText const QString   text [signal]
 

Emited by the part, to set a text in the statusbar of the window(s) hosting this part.

void Part::setWidget QWidget   widget [protected, virtual]
 

Set the main widget.

Call this in the Part-inherited class constructor.

Definition at line 191 of file part.cpp.

References KXMLGUIClient::actionCollection(), QObject::connect(), QObject::destroyed(), KActionCollection::setAutoConnectShortcuts(), and KActionCollection::setWidget().

void Part::partActivateEvent PartActivateEvent   event [protected, virtual]
 

Convenience method which is called when the Part received a PartActivateEvent .

Reimplement this if you don't want to reimplement event and test for the event yourself or even install an event filter.

Definition at line 241 of file part.cpp.

void Part::partSelectEvent PartSelectEvent   event [protected, virtual]
 

Convenience method which is called when the Part received a PartSelectEvent .

Reimplement this if you don't want to reimplement event and test for the event yourself or even install an event filter.

Definition at line 245 of file part.cpp.

void Part::guiActivateEvent GUIActivateEvent   event [protected, virtual]
 

Convenience method which is called when the Part received a GUIActivateEvent .

Reimplement this if you don't want to reimplement event and test for the event yourself or even install an event filter.

Reimplemented in KParts::ReadOnlyPart.

Definition at line 249 of file part.cpp.

QWidget * Part::hostContainer const QString   containerName [protected]
 

Convenience method for KXMLGUIFactory::container.

Returns:
a container widget owned by the Part's GUI.

Definition at line 253 of file part.cpp.
