Detailed Description
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.

- the desktop number, -1 for all desktops and less than -1 for none
Definition at line 196 of file view.cpp.
int Plasma::View::effectiveDesktop |
( |
|
) |
const |
The virtual desktop this view is actually being viewed on.
- Returns:

Definition at line 205 of file view.cpp.
int Plasma::View::id |
( |
|
) |
const |

const |
- Returns:
- whether or not containments should draw wallpaper
Definition at line 363 of file view.cpp.
void Plasma::View::sceneRectAboutToChange |
( |
|
) |
[signal] |
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
void Plasma::View::sceneRectChanged |
( |
|
) |
[signal] |
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.
int Plasma::View::screen |
( |
|
) |
const |
Returns the screen this view is associated with.
- Returns:
- the xinerama screen number, or -1 for none
Definition at line 191 of file view.cpp.
Sets the containment for this view, which will also cause the view to track the geometry of the containment.
- containment the containment to center the view on
Definition at line 211 of file view.cpp.
void Plasma::View::setScreen |
( |
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
- screen the physical screen number; -1 for no screen
- desktop the virtual desktop number, or -1 for all virtual desktops
Definition at line 167 of file view.cpp.
void Plasma::View::setTrackContainmentChanges |
( |
bool |
trackChanges |
) |
|
Set whether or not the view should adjust its size when the associated containment does.
- trackChanges true to synchronize the view's size with the containment's (this is the default behaviour), false to ignore containment size changes
