Namespace: Plasma
Detailed Description
View plasma/view.h <Plasma/View>
A QGraphicsView for a single Containment
Each View is associated with a Plasma.Containment and tracks geometry changes, maps to the current desktop (if any) among other helpful utilities. It isn't stricly required to use a Plasma.View with Plasma enabled applications, but it can make some things easier.

Method Documentation
__init__ | ( | self, | ||
Plasma.Containment | containment, | |||
QWidget | parent=0 | |||
) |
Constructs a view for a given contanment. An Id is automatically assigned to the View.
@arg containment the containment to center the view on @arg parent the parent object for this view
__init__ | ( | self, | ||
Plasma.Containment | containment, | |||
int | viewId, | |||
QWidget | parent=0 | |||
) |
Constructs a view for a given contanment.
@arg containment the containment to center the view on @arg viewId the id to assign to this view @arg parent the parent object for this view
KConfigGroup config | ( | self ) |
- Returns:
- a KConfigGroup in the application's config file unique to the view
configNeedsSaving | ( | self ) |
Requests that the config be synchronized to disk
Plasma.Containment containment | ( | self ) |
- Returns:
- the containment associated with this view, or 0 if none is
int desktop | ( | self ) |
The virtual desktop this view is associated with
- Returns:
- the desktop number, -1 for all desktops and less than -1 for none
int effectiveDesktop | ( | self ) |
The virtual desktop this view is actually being viewed on
- Returns:
- the desktop number (always valid, never < 0)
int id | ( | self ) |
- Returns:
- the id of the View set in the constructor
bool isWallpaperEnabled | ( | self ) |
- Returns:
- whether or not containments should draw wallpaper
sceneRectAboutToChange | ( | self ) |
This signal is emitted whenever the containment being viewed has changed its geometry, but before the View has shifted the viewd scene rect to the new geometry. This is useful for Views which want to keep their rect() in sync with the containment'sa
- Signal syntax:
QObject.connect(source, SIGNAL("sceneRectAboutToChange()"), target_slot)
sceneRectChanged | ( | self ) |
This signal is emitted whenever the containment being viewed has changed its geometry, and after the View has shifted the viewd scene rect to the new geometry. This is useful for Views which want to keep their rect() in sync with the containment's.
- Signal syntax:
QObject.connect(source, SIGNAL("sceneRectChanged()"), target_slot)
int screen | ( | self ) |
Returns the screen this view is associated with
- Returns:
- the xinerama screen number, or -1 for none
setContainment | ( | self, | ||
Plasma.Containment | containment | |||
) |
Sets the containment for this view, which will also cause the view to track the geometry of the containment.
@arg containment the containment to center the view on
setScreen | ( | self, | ||
int | screen, | |||
int | desktop=-1 | |||
) |
Sets which screen this view is associated with, if any. This will also set the containment if a valid screen is specified
@arg screen the physical screen number; -1 for no screen @arg desktop the virtual desktop number, or -1 for all virtual desktops
setTrackContainmentChanges | ( | self, | ||
bool | trackChanges | |||
) |
Set whether or not the view should adjust its size when the associated containment does. @arg trackChanges true to synchronize the view's size with the containment's (this is the default behaviour), false to ignore containment size changes
setWallpaperEnabled | ( | self, | ||
bool | draw | |||
) |
Sets whether or not to draw the containment wallpaper when painting on this item
Plasma.Containment swapContainment | ( | self, | ||
Plasma.Containment | existing, | |||
QString | name, | |||
QVariantList | args=QVariantList() | |||
) |
Swaps one containment with another.
- Parameters:
-
existing the existing containment to swap out name the plugin name for the new containment. args argument list to pass to the containment
- Returns:
- the new containment
Plasma.Containment swapContainment | ( | self, | ||
QString | name, | |||
QVariantList | args=QVariantList() | |||
) |
Swap the containment for this view, which will also cause the view to track the geometry of the containment.
- Parameters:
-
name the plugin name for the new containment. args argument list to pass to the containment
Plasma.View topLevelViewAt | ( | QPoint | pos | |
) |
- Parameters:
-
pos the position in screen coordinates.
- Returns:
- the Plasma.View that is at position pos.
bool trackContainmentChanges | ( | self ) |
- Returns:
- whether or not the view tracks changes to the containment
