Detailed Description

KSelector is the base class for other widgets which provides the ability to choose from a one-dimensional range of values. An example is the KGradientSelector which allows to choose from a range of colors.

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

Constructor & Destructor Documentation

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

Constructs a horizontal one-dimensional selection widget.

KSelector::KSelector (  Orientation    o, QWidget *    parent = 0L, const char *    name = 0L )

Constructs a one-dimensional selection widget with a given orientation.

Member Function Documentation

QRect KSelector::contentsRect (    )

Returns: the rectangle on which subclasses should draw.

virtual void KSelector::drawArrow (  QPainter *    painter, bool    show, const QPoint &    pos )  [protected, virtual]

Override this function to draw the cursor which indicates the current value. This function is always called twice, once with argument show=false to clear the old cursor, once with argument show=true to draw the new one.

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

Override this function to draw the contents of the control. The default implementation does nothing. Draw only within contentsRect(). Reimplemented in KValueSelector, and KGradientSelector.

bool KSelector::indent (    )  const [inline]

Returns: whether the indent option is set. Definition at line 184 of file kselect.h.

int KSelector::maxValue (    )  const [inline]

Returns: the max value. Definition at line 220 of file kselect.h.

int KSelector::minValue (    )  const [inline]

Returns: the min value. Definition at line 208 of file kselect.h.

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

@reimplemented

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

@reimplemented

Orientation KSelector::orientation (    )  const [inline]

Returns: the orientation of the widget. Definition at line 167 of file kselect.h.

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

@reimplemented

void KSelector::setIndent (  bool    i )  [inline]

Sets the indent option of the widget to i. This determines whether a shaded frame is drawn. Definition at line 179 of file kselect.h.

void KSelector::setMaxValue (  int    value )  [inline]

Sets the max value. Definition at line 214 of file kselect.h. References value().

void KSelector::setMinValue (  int    value )  [inline]

Sets the min value. Definition at line 202 of file kselect.h. References value().

void KSelector::setValue (  int    value )  [inline]

Sets the value. Definition at line 190 of file kselect.h. References value().

int KSelector::value (    )  const [inline]

Returns: the value. Definition at line 196 of file kselect.h. Referenced by setMaxValue(), setMinValue(), and setValue().

virtual void KSelector::valueChange (    )  [protected, virtual]

@reimplemented

void KSelector::valueChanged (  int    value )  [signal]

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