The part manager is an object which knows about a collection of parts (even nested ones) and handles activation/deactivation.
Applications that want to embed parts without merging GUIs only use a KParts::PartManager. Those who want to merge GUIs use a KParts::MainWindow for example, in addition to a part manager.
Parts know about the part manager to add nested parts to it. See also KParts::Part::manager() and KParts::Part::setManager().
| enum SelectionPolicy { Direct, TriState } | SelectionPolicy |
| PartManager ( QWidget * parent, const char * name = 0L )
| PartManager |
Constructs a part manager.
Parameters:
| parent | The toplevel widget (window / dialog) the partmanager should monitor for activation/selection events |
| PartManager ( QWidget * topLevel, QObject *parent, const char *name = 0 )
| PartManager |
Constructs a part manager.
Parameters:
| topLevel | The toplevel widget (window / dialog ) the partmanager should monitor for activation/selection events |
| parent | The parent QObject. |
| ~PartManager ()
| ~PartManager |
[virtual]
| void setSelectionPolicy ( SelectionPolicy policy )
| setSelectionPolicy |
Sets the selection policy of the partmanager.
| SelectionPolicy selectionPolicy ()
| selectionPolicy |
[const]
Returns the current selection policy.
| void setAllowNestedParts ( bool allow )
| setAllowNestedParts |
Specifies whether the partmanager should handle/allow nested parts or not.
This is a property the shell has to set/specify. Per default we assume that the shell cannot handle nested parts. However in case of a KOffice shell for example we allow nested parts. A Part is nested (a child part) if its parent object inherits KParts::Part. If a child part is activated and nested parts are not allowed/handled, then the top parent part in the tree is activated.
| bool allowNestedParts ()
| allowNestedParts |
[const]
See also: setAllowNestedParts
| void setIgnoreScrollBars ( bool ignore )
| setIgnoreScrollBars |
Specifies whether the partmanager should ignore mouse click events for scrollbars or not. If the partmanager ignores them, then clicking on the scrollbars of a non-active/non-selected part will not change the selection or activation state.
The default value is false (read: scrollbars are NOT ignored).
| bool ignoreScrollBars ()
| ignoreScrollBars |
[const]
See also: setIgnoreScrollBars
| bool eventFilter ( QObject *obj, QEvent *ev )
| eventFilter |
[virtual]
| void addPart ( Part *part, bool setActive = true )
| addPart |
[virtual]
Adds a part to the manager.
Sets it to the active part automatically if setActive is true (default ).
| void removePart ( Part *part )
| removePart |
[virtual]
Removes a part from the manager (this does not delete the object) .
Sets the active part to 0 if part is the activePart() .
| void replacePart ( Part * oldPart, Part * newPart, bool setActive = true )
| replacePart |
[virtual]
Replaces oldPart with newPart, and sets newPart as active if
setActive is true.
This is an optimised version of removePart + addPart
| void setActivePart ( Part *part, QWidget *widget = 0L )
| setActivePart |
[virtual]
Sets the active part.
The active part receives activation events.
widget can be used to specify which widget was responsible for the activation.
This is important if you have multiple views for a document/part , like in KOffice .
| Part * activePart ()
| activePart |
[const virtual]
Returns the active part.
| QWidget * activeWidget ()
| activeWidget |
[const virtual]
Returns the active widget of the current active part (see activePart ).
| void setSelectedPart ( Part *part, QWidget *widget = 0L )
| setSelectedPart |
[virtual]
Sets the selected part.
The selected part receives selection events.
widget can be used to specify which widget was responsible for the selection.
This is important if you have multiple views for a document/part , like in KOffice .
| Part * selectedPart ()
| selectedPart |
[const virtual]
Returns the current selected part.
| QWidget * selectedWidget ()
| selectedWidget |
[const virtual]
Returns the selected widget of the current selected part (see selectedPart ).
| const QPtrList | parts |
[const]
Returns the list of parts being managed by the partmanager.
| void addManagedTopLevelWidget ( const QWidget *topLevel )
| addManagedTopLevelWidget |
Adds the topLevel widget to the list of managed toplevel widgets.
Usually a PartManager only listens for events (for activation/selection)
for one toplevel widget (and its children) , the one specified in the
constructor. Sometimes however (like for example when using the KDE dockwidget
library) , it is necessary to extend this.
| void removeManagedTopLevelWidget ( const QWidget *topLevel )
| removeManagedTopLevelWidget |
Removes the topLevel widget from the list of managed toplevel widgets.
See also: addManagedTopLevelWidget
| void partAdded ( KParts::Part *part )
| partAdded |
[signal]
Emitted when a new part has been added.
See also: addPart()
| void partRemoved ( KParts::Part *part )
| partRemoved |
[signal]
Emitted when a part has been removed.
See also: removePart()
| void activePartChanged ( KParts::Part *newPart )
| activePartChanged |
[signal]
Emitted when the active part has changed.
See also: setActivePart()
| void setActiveInstance ( KInstance * instance )
| setActiveInstance |
[protected virtual]
Changes the active instance when the active part changes. The active instance is used by KBugReport and KAboutDialog. Override if you really need to - usually you don't need to.
| void slotObjectDestroyed ()
| slotObjectDestroyed |
[protected slots slot]
Removes a part when it is destroyed.
| void slotWidgetDestroyed ()
| slotWidgetDestroyed |
[protected slots slot]
| void slotManagedTopLevelWidgetDestroyed ()
| slotManagedTopLevelWidgetDestroyed |
[protected slots slot]
| void virtual_hook ( int id, void* data )
| virtual_hook |
[protected virtual]
