Detailed Description

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

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

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

Constructs a horizontal one-dimensional selection widget. Definition at line 217 of file oselector.cpp. References _indent, _orientation, and TRUE.

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

Constructs a one-dimensional selection widget with a given orientation. Definition at line 224 of file oselector.cpp. References _indent, _orientation, and TRUE.

OSelector::~OSelector (   )

Definition at line 232 of file oselector.cpp.

Member Function Documentation

QPoint OSelector::calcArrowPos (  int  val  )  [private]

Definition at line 323 of file oselector.cpp. References height, maxValue(), minValue(), orientation(), p, and width. Referenced by paintEvent(), and valueChange().

QRect OSelector::contentsRect (   )  const

Returns: the rectangle on which subclasses should draw. Definition at line 236 of file oselector.cpp. References height, orientation(), and width. Referenced by Opie::Ui::OValueSelector::drawContents(), Opie::Ui::OGradientSelector::drawContents(), and Opie::Ui::OValueSelector::drawPalette().

void OSelector::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. Definition at line 346 of file oselector.cpp. References orientation(). Referenced by paintEvent(), and valueChange().

void OSelector::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 Opie::Ui::OGradientSelector, and Opie::Ui::OValueSelector. Definition at line 343 of file oselector.cpp. Referenced by paintEvent().

bool Opie::Ui::OSelector::indent (   )  const [inline]

Returns: whether the indent option is set. Definition at line 193 of file oselector.h. References _indent. Referenced by paintEvent().

int Opie::Ui::OSelector::maxValue (   )  const [inline]

Returns: the max value. Definition at line 235 of file oselector.h. Referenced by calcArrowPos(), and moveArrow().

int Opie::Ui::OSelector::minValue (   )  const [inline]

Returns: the min value. Definition at line 220 of file oselector.h. Referenced by calcArrowPos(), and moveArrow().

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

Definition at line 275 of file oselector.cpp. References moveArrow().

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

Definition at line 270 of file oselector.cpp. References moveArrow().

void OSelector::moveArrow (  const QPoint &  pos  )  [private]

Definition at line 303 of file oselector.cpp. References height, maxValue(), minValue(), orientation(), setValue(), val, valueChanged(), and width. Referenced by mouseMoveEvent(), and mousePressEvent().

Orientation Opie::Ui::OSelector::orientation (   )  const [inline]

Returns: the orientation of the widget. Definition at line 176 of file oselector.h. References _orientation. Referenced by calcArrowPos(), contentsRect(), drawArrow(), Opie::Ui::OGradientSelector::drawContents(), Opie::Ui::OValueSelector::drawPalette(), moveArrow(), and paintEvent().

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

Definition at line 244 of file oselector.cpp. References calcArrowPos(), drawArrow(), drawContents(), height, indent(), orientation(), pos, TRUE, value(), and width.

void Opie::Ui::OSelector::setIndent (  bool  i  )  [inline]

Sets the indent option of the widget to i. This determines whether a shaded frame is drawn. Definition at line 188 of file oselector.h. References _indent.

void Opie::Ui::OSelector::setMaxValue (  int  value  )  [inline]

Sets the max value. Definition at line 227 of file oselector.h.

void Opie::Ui::OSelector::setMinValue (  int  value  )  [inline]

Sets the min value. Definition at line 212 of file oselector.h.

void Opie::Ui::OSelector::setValue (  int  value  )  [inline]

Sets the value. Definition at line 199 of file oselector.h. Referenced by moveArrow(), and wheelEvent().

int Opie::Ui::OSelector::value (   )  const [inline]

Returns: the value. Definition at line 205 of file oselector.h. Referenced by paintEvent(), valueChange(), and wheelEvent().

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

Definition at line 287 of file oselector.cpp. References calcArrowPos(), drawArrow(), FALSE, pos, TRUE, and value().

void Opie::Ui::OSelector::valueChanged (  int  value  )  [signal]

This signal is emitted whenever the user chooses a value, e.g. by clicking with the mouse on the widget. Referenced by moveArrow(), and wheelEvent().

void OSelector::wheelEvent (  QWheelEvent *   )  [protected, virtual]

Definition at line 280 of file oselector.cpp. References setValue(), val, value(), and valueChanged().
