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 (  QWidget *    parent = 0, const char *    name = 0 )

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

KXYSelector::~KXYSelector (    )

Destructs the widget.

Member Function Documentation

QRect KXYSelector::contentsRect (    )

Returns: the rectangle on which subclasses should draw.

virtual void KXYSelector::drawContents (  QPainter *    )  [protected, virtual]

Override this function to draw the contents of the widget. The default implementation does nothing. Draw within contentsRect() only. Reimplemented in KHSSelector.

virtual void KXYSelector::drawCursor (  QPainter *    p, int    xp, int    yp )  [protected, virtual]

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

virtual void KXYSelector::mouseMoveEvent (  QMouseEvent *    e )  [protected, virtual]

@reimplemented

virtual void KXYSelector::mousePressEvent (  QMouseEvent *    e )  [protected, virtual]

@reimplemented

virtual void KXYSelector::paintEvent (  QPaintEvent *    e )  [protected, virtual]

@reimplemented

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

Sets the range of possible values.

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

Sets the current values in horizontal and vertical direction.

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.

int KXYSelector::xValue (    )  const [inline]

Returns: the current value in horizontal direction. Definition at line 69 of file kselect.h.

int KXYSelector::yValue (    )  const [inline]

Returns: the current value in vertical direction. Definition at line 73 of file kselect.h.
