Member Function Documentation

void DesktopLayout::addItem	(	QGraphicsWidget *	item,
		bool	pushBack = true,
		bool	position = true
	)

Adds a new item.

Parameters:

	item	the item to add
	pushBack	if the item should attempt to always be in its preferred position; if false, it will only move when pushed by other items or edges of the working area
	position	if the item should be repositioned

Definition at line 32 of file desktoplayout.cpp.

void DesktopLayout::adjustPhysicalPositions

(

)

Adjusts the items' on-screen positions to match calculations.

Definition at line 289 of file desktoplayout.cpp.

int DesktopLayout::count

)

const

Returns the count of items in the layout.

Definition at line 193 of file desktoplayout.cpp.

QRectF DesktopLayout::getLastGeometry

(

int

index

)

Definition at line 144 of file desktoplayout.cpp.

QPointF DesktopLayout::getPreferredPosition

(

int

index

)

Definition at line 135 of file desktoplayout.cpp.

bool DesktopLayout::getPushBack

(

int

index

)

Definition at line 126 of file desktoplayout.cpp.

const

Returns the applet at the specified position.

Definition at line 198 of file desktoplayout.cpp.

void DesktopLayout::itemTransformed	(	QGraphicsWidget *	item,
		ItemTransformType	type
	)

Call this when an item has been moved/resized/transformed either by the user or itself.

Parameters:

	item	the item affected
	type	whether the change was by the user (ItemTransformUser) or the applet itself (ItemTransformSelf)

Definition at line 335 of file desktoplayout.cpp.

void DesktopLayout::removeAt

(

int

void DesktopLayout::setAlignment

(

Qt::Alignment

alignment

)

Sets the alignment.

This defines the sides of the working area where items are pushed inside in case the working area shrinks. Default is Qt::AlignTop|QtAlignLeft which pushes items on the right and the bottom sides.

Definition at line 183 of file desktoplayout.cpp.

void DesktopLayout::setPlacementSpacing

(

qreal

Definition at line 153 of file desktoplayout.cpp.

void DesktopLayout::setScreenSpacing

(

qreal

spacing

Sets spacing between an item and the edge of the working area when items are being pushed around and when an item is moved by the user.

Definition at line 158 of file desktoplayout.cpp.

void DesktopLayout::setShiftingSpacing
