Detailed Description

Inherits QSpinBox and extends it to support double-precision floating-point numbers.

Benefits of this method of this approach: the widget looks and feels exactly like the normal integer spin box.

Note: Unlike QSpinBox, this reimplemention does NOT calculate the minimum width for the widget. Instead it will expdand to fill the entrie allocated area.

Constructor & Destructor Documentation

SuperSpinBox::SuperSpinBox (  QWidget *  parent = NULL, const char *  name = NULL )

Constructor. This will initialize the double's min, max and line step values to their defaults of 0.0, 99.0 and 1.0 (respectively).

SuperSpinBox::SuperSpinBox (  double  minValue, double  maxValue, double  step = DEFAULT_STEP_VALUE, QWidget *  parent = NULL, const char *  name = NULL )

Constructor. This constructor takes the double's min, max and line step values as parameters, instead of using defaults.

Member Function Documentation

double SuperSpinBox::lineStep (   )  const [inline]

int SuperSpinBox::mapTextToValue (  bool *  ok  )  [protected, virtual]

Reimplemented as to get the lastest DOUBLE value from the editor widget.

QString SuperSpinBox::mapValueToText (  int   )  [protected, virtual]

Map the value of the double value to its actual string representation.

double SuperSpinBox::maxValue (   )  const [inline]

double SuperSpinBox::minValue (   )  const [inline]

void SuperSpinBox::rangeChange (   )  [protected, virtual]

Reimplemented as to update the editor's validator and to enable/disable the up and down arrow buttons.

void SuperSpinBox::setLineStep (  double  step  )

Reimplemented as to update the double's line step (increment/decrement) value.

void SuperSpinBox::setMaxValue (  double  max  )

Reimplemented as to update the double max value and the editor's validator.

void SuperSpinBox::setMinValue (  double  min  )

Reimplemented as to update the double min value and the editor's validator.

void SuperSpinBox::setValue (  double  value  )  [virtual, slot]

Reimplemented as to update the double value and to update the editor widget.

void SuperSpinBox::sharedInit (   )  [private]

This method is used by the constructors to perform tasks that are common to all of them.

void SuperSpinBox::stepDown (   )  [virtual, slot]

Decrement the double value by d_lineStep and update the editor widget.

void SuperSpinBox::stepUp (   )  [virtual, slot]

Increment the double value by d_lineStep and update the editor widget.

double SuperSpinBox::value (   )  const [inline]

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

This looks after things that need to be updated when the value is changed. It will look after bounds checks and enabling / disabling the up and down buttons, update the text display and emit the SuperSpinBox::valueChanged() signals. Note: This does not call the parent's valueChange, as we don't want to emit the integer-based signals.

void SuperSpinBox::valueChanged (  const QString &  valueText  )  [signal]

void SuperSpinBox::valueChanged (  double  value  )  [signal]
