Detailed Description

The Scratchpad class A scratchpad is a type of blank canvas area that can be painted on with the normal painting devices.

Definition at line 27 of file Scratchpad.h.

Constructor & Destructor Documentation

◆ Scratchpad()

Scratchpad::Scratchpad ( View * view,
const QColor & defaultColor,
QWidget * parent = 0 )

Definition at line 27 of file Scratchpad.cpp.

◆ ~Scratchpad()

Scratchpad::~Scratchpad ( )

Definition at line 47 of file Scratchpad.cpp.

Member Function Documentation

◆ canvasZoomLink

bool Scratchpad::canvasZoomLink ( )
slot

return if scratchpad zoom level is linked with current view zoom level

Returns
return True if connection between the zoom of the canvas and scratchpad (so they zoom in sync) is active

Definition at line 72 of file Scratchpad.cpp.

◆ clear

void Scratchpad::clear ( )
slot

Clears out scratchpad with color specified set during setup.

Definition at line 130 of file Scratchpad.cpp.

◆ contentBounds

QRect Scratchpad::contentBounds ( ) const
slot

The content of scratchpad can be bigger or smaller than scratchpad dimension.

The bounds return the area in which there's some content

Returns
scratchpad content bounds as a QRect

Definition at line 221 of file Scratchpad.cpp.

◆ contentChanged

void Scratchpad::contentChanged ( )
signal

signal is emitted when scratchpad content is changed (stroke or fill)

◆ copyScratchpadImageData

QImage Scratchpad::copyScratchpadImageData ( )
slot

Take what is on the scratchpad area and grab image.

Returns
the image data from the scratchpad

Definition at line 125 of file Scratchpad.cpp.

◆ fillBackground

void Scratchpad::fillBackground ( )
slot

Fill the entire scratchpad with current background color.

Definition at line 151 of file Scratchpad.cpp.

◆ fillDefault

void Scratchpad::fillDefault ( )
slot

Fill the entire scratchpad with default color.

Definition at line 141 of file Scratchpad.cpp.

◆ fillDocument

void Scratchpad::fillDocument ( bool fullContent = true)
slot

Fill the entire scratchpad with current document projection content.

Parameters
fullContentwhen True, full document projection is loaded in scratchpad, otherwise only content matching scratchpad viewport is loaded

Definition at line 206 of file Scratchpad.cpp.

◆ fillForeground

void Scratchpad::fillForeground ( )
slot

Fill the entire scratchpad with current foreground color.

Definition at line 156 of file Scratchpad.cpp.

◆ fillGradient

void Scratchpad::fillGradient ( const QPoint & gradientVectorStart = QPoint(),
const QPoint & gradientVectorEnd = QPoint(),
const QString & gradientShape = "linear",

bool reverseGradient = false,
bool dither = false )
slot

Fill the entire scratchpad with current gradient.

Parameters
gradientVectorStartis a QPoint to define origin of gradient Set an empty QPoint() to use default scratchpad top-left
gradientVectorEndis a QPoint to define end of gradient set an empty QPoint() to use default scratchpad bottom-right
gradientShapedefine which gradient to apply, can be:
  • "linear"
  • "bilinear"
  • "radial"
  • "square"
  • "conical"
  • "conicalSymmetric"
  • "spiral"
  • "reverseSpiral"
  • "polygonal"
gradientRepeatdefine how to repeat gradient, can be:
  • "none"
  • "alternate"
  • "forwards"
reverseGradienta boolean to define if gradient is reversed or not
dithera boolean to define if gradient is dithered or not

Definition at line 161 of file Scratchpad.cpp.

◆ fillLayer

void Scratchpad::fillLayer ( bool fullContent = true)
slot

Fill the entire scratchpad with current layer content.
