KDE 4.0 API Reference KParts
KParts::Part Class Reference
#include <part.h>
Detailed Description
Base class for parts.A "part" is a GUI component, featuring:
- A widget embeddedable in any application.
- GUI elements that will be merged in the "host" user interface (menubars, toolbars... ).
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.

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.

| void Part::setManager | ( | PartManager * | manager | ) | [virtual] |
| PartManager * Part::manager | ( | ) | const |
| void Part::setAutoDeleteWidget | ( | bool | autoDeleteWidget | ) |
By default, the widget is deleted by the part when the part is deleted.
The hosting application can call setAutoDeleteWidget(false) to disable this behavior, given that the widget is usually deleted by its parent widget anyway. This is a method for the hosting application only, Part subclasses should never call this.
| void Part::setAutoDeletePart | ( | bool | autoDeletePart | ) |
By default, the part deletes itself when its widget is deleted.
The hosting application can call setAutoDeletePart(false) to disable this behavior, to be able to delete the widget and then the part, independently. This is a method for the hosting application only, Part subclasses should never call this.
Returns the part (this, or a child part) at the given global position.
This is called by the part manager to ask whether a part should be activated when clicking somewhere. In most cases the default implementation is enough. Reimplement this if your part has child parts in some areas (like in khtml or koffice)
- Parameters:
-
widget the part widget being clicked - usually the same as widget(), except in koffice. globalPos the mouse coordinates in global coordinates
| void Part::setSelectable | ( | bool | selectable | ) | [virtual] |
| bool Part::isSelectable | ( | ) | const |
| KIconLoader * Part::iconLoader | ( | ) |
Use this icon loader to load any icons that are specific to this part, i.e.
icons installed into this part's own directories as opposed to standard kde icons. Use KIcon("myicon", iconLoader()).
Make sure to call setComponentData before calling iconLoader.
| void KParts::Part::setWindowCaption | ( | const QString & | caption | ) | [signal] |
Emitted by the part, to set the caption of the window(s) hosting this part.
| 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] |
| void Part::customEvent | ( | QEvent * | event | ) | [protected, virtual] |
| 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.
| 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.
| 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.
Convenience method for KXMLGUIFactory::container.
- Returns:
- a container widget owned by the Part's GUI.
