KXYSelector Class Reference

from PyKDE4.kdeui import *

Inherits: QWidget → QObject
Subclasses: KHueSaturationSelector

Detailed Description

KXYSelector is the base class for other widgets which provides the ability to choose from a two-dimensional range of values. The currently chosen value is indicated by a cross. An example is the KHSSelector which allows to choose from a range of colors, and which is used in KColorDialog.

A custom drawing routine for the widget surface has to be provided by the subclass.

Method Documentation

__init__	(	self,
		QWidget	parent=0
	)

Constructs a two-dimensional selector widget which has a value range of [0..100] in both directions.

__init__	(	self,
		KXYSelector	a0
	)

QRect contentsRect ( self )

Returns:: the rectangle on which subclasses should draw.

drawContents	(	self,
		QPainter	a0
	)

Override this function to draw the contents of the widget. The default implementation does nothing.

Draw within contentsRect() only.

drawMarker	(	self,
		QPainter	p,
		int	xp,
		int	yp
	)

Override this function to draw the marker which indicates the currently selected value pair.

QSize minimumSizeHint ( self )

Reimplemented to give the widget a minimum size

mouseMoveEvent	(	self,
		QMouseEvent	e
	)

mousePressEvent	(	self,
		QMouseEvent	e
	)

paintEvent	(	self,
		QPaintEvent	e
	)

setMarkerColor	(	self,
		QColor	col
	)

Sets the color used to draw the marker

Parameters:

col

the color

setRange	(	self,
		int	minX,
		int	minY,
		int	maxX,
		int	maxY
	)

Sets the range of possible values.

setValues	(	self,
		int	xPos,
		int	yPos
	)

Sets the current values in horizontal and vertical direction.

Parameters:

	xPos	the horizontal value
	yPos	the vertical value

setXValue	(	self,
		int	xPos
	)

Sets the current horizontal value

Parameters:

xPos

the horizontal value

setYValue	(	self,
		int	yPos
	)

Sets the current vertical value

Parameters:

yPos

the vertical value

valueChanged	(	self,
		int	x,
		int	y
	)

This signal is emitted whenever the user chooses a value, e.g. by clicking with the mouse on the widget.

Signal syntax:: QObject.connect(source, SIGNAL("valueChanged(int, int)"), target_slot)

, int (xVal), int (yVal) valuesFromPosition	(	self,
		int	x,
		int	y,
	)

Converts a pixel position to its corresponding values.

wheelEvent	(	self,
		QWheelEvent	a0
	)

int xValue ( self )

Returns:: the current value in horizontal direction.

int yValue ( self )

Returns:: the current value in vertical direction.
