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.

Constructor & Destructor Documentation

KXYSelector()

KXYSelector::KXYSelector	(	TQWidget *	parent = 0,
		const char *	name = 0
	)

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

Definition at line 36 of file tdeselect.cpp.

~KXYSelector()

KXYSelector::~KXYSelector

(

)

Destructs the widget.

Definition at line 50 of file tdeselect.cpp.

Member Function Documentation

contentsRect()

TQRect KXYSelector::contentsRect

(

)

const

Returns

the rectangle on which subclasses should draw.

Definition at line 99 of file tdeselect.cpp.

drawContents()

void KXYSelector::drawContents ( TQPainter *  )

protectedvirtual

Override this function to draw the contents of the widget.

The default implementation does nothing.

Draw within contentsRect() only.

Reimplemented in KHSSelector.

Definition at line 217 of file tdeselect.cpp.

drawCursor()

void KXYSelector::drawCursor ( TQPainter *  p, int  xp, int  yp  )

protectedvirtual

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

Definition at line 221 of file tdeselect.cpp.

setRange()

void KXYSelector::setRange	(	int	minX,
		int	minY,
		int	maxX,
		int	maxY
	)

Sets the range of possible values.

Definition at line 54 of file tdeselect.cpp.

setValues()

void KXYSelector::setValues	(	int	xPos,
		int	yPos
	)

Sets the current values in horizontal and vertical direction.

Parameters

xPos	the horizontal value
yPos	the veritcal value

Definition at line 75 of file tdeselect.cpp.

setXValue()

void KXYSelector::setXValue

(

int

xPos

)

Sets the current horizontal value.

Parameters

xPos	the horizontal value

Definition at line 65 of file tdeselect.cpp.

setYValue()

void KXYSelector::setYValue

(

int

yPos

)

Sets the current vertical value.

Parameters

yPos	the veritcal value

Definition at line 70 of file tdeselect.cpp.

valueChanged

void KXYSelector::valueChanged ( int  x, int  y  )

signal

This signal is emitted whenever the user chooses a value, e.g.

by clicking with the mouse on the widget.

valuesFromPosition()

void KXYSelector::valuesFromPosition ( int  x, int  y, int &  xVal, int &  yVal  ) const

protected

Converts a pixel position to its corresponding values.

Definition at line 171 of file tdeselect.cpp.

xValue()

int KXYSelector::xValue ( ) const

inline

Returns

the current value in horizontal direction.

Definition at line 88 of file tdeselect.h.

yValue()

int KXYSelector::yValue ( ) const

inline

Returns

the current value in vertical direction.

Definition at line 92 of file tdeselect.h.
