Detailed Description

KisSelection contains a byte-map representation of a layer, where the value of a byte signifies whether a corresponding pixel is selected, or not.

NOTE: If you need to manually call emitSelectionChanged on the owner paint device of a selection. KisSelection does not emit any signals by itself because often you want to combine several actions in to perfom one operation and you do not want recomposition to happen all the time.

Constructor & Destructor Documentation

KisSelection() [1/3]

KisSelection::KisSelection

(

KisPaintDeviceSP

dev

)

Create a new KisSelection.

Parameters

dev	the parent paint device. The selection will never be bigger than the parent paint device.

Definition at line 37 of file kis_selection.cpp.

KisSelection() [2/3]

KisSelection::KisSelection

(

)

Create a new KisSelection.

This selection will not have a parent paint device.

Definition at line 48 of file kis_selection.cpp.

KisSelection() [3/3]

KisSelection::KisSelection

(

const KisSelection &

rhs

)

Copy the selection.

Definition at line 54 of file kis_selection.cpp.

~KisSelection()

KisSelection::~KisSelection ( )

virtual

Definition at line 60 of file kis_selection.cpp.

Member Function Documentation

clear() [1/2]

void KisSelection::clear ( )

virtual

Complete erase the current paint device.

Its size will become 0.

Reimplemented from KisPaintDevice.

Definition at line 128 of file kis_selection.cpp.

clear() [2/2]

void KisSelection::clear

(

TQRect

r

)

Definition at line 121 of file kis_selection.cpp.

interestedInDirtyness()

bool KisSelection::interestedInDirtyness ( ) const

inline

Definition at line 114 of file kis_selection.h.

invert()

void KisSelection::invert

(

)

Definition at line 135 of file kis_selection.cpp.

isProbablyTotallyUnselected()

bool KisSelection::isProbablyTotallyUnselected

(

TQRect

r

)

Tests if the the rect is totally outside the selection, but uses selectedRect instead of selectedRect, and this is faster (but might deliver false positives!).

XXX: This comment makes no sense anymore! (BSAR)

Definition at line 160 of file kis_selection.cpp.

isTotallyUnselected()

bool KisSelection::isTotallyUnselected

(

TQRect

r

)

Tests if the the rect is totally outside the selection.

Reimplemented from KisPaintDevice.

Definition at line 578 of file kis_selection.cpp.

setDirty() [2/2]

void KisSelection::setDirty ( const TQRect & rc )

virtual

Add the specified rect top the parent layer (if present).
