Detailed Description

DSelector 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.

Member Function Documentation

arrowDirection()

Qt::ArrowType Digikam::DSelector::arrowDirection

(

)

const

Returns

the current arrow direction

contentsRect()

QRect Digikam::DSelector::contentsRect

(

)

const

Returns

the rectangle on which subclasses should draw.

References arrowDirection, and indent.

Referenced by Digikam::DColorValueSelector::drawContents(), and Digikam::DColorValueSelector::drawPalette().

drawArrow()

void Digikam::DSelector::drawArrow ( QPainter *  painter, const QPoint &  pos  )

protectedvirtual

Override this function to draw the cursor which indicates the current value.

Referenced by paintEvent().

drawContents()

virtual void Digikam::DSelector::drawContents ( QPainter *  )

inlineprotectedvirtual

Override this function to draw the contents of the control. The default implementation does nothing.

Draw only within contentsRect().

Reimplemented in Digikam::DColorValueSelector.

Referenced by paintEvent().

indent()

bool Digikam::DSelector::indent

(

)

const

Returns

whether the indent option is set.

mouseMoveEvent()

setArrowDirection()

void Digikam::DSelector::setArrowDirection

(

Qt::ArrowType

direction

)

Sets the arrow direction.

Referenced by DSelector().

setIndent()

void Digikam::DSelector::setIndent

(

bool

i

)

Sets the indent option of the widget to i. This determines whether a shaded frame is drawn.

wheelEvent()

void Digikam::DSelector::wheelEvent ( QWheelEvent *  e )

overrideprotected

References value.
