Detailed Description

Instances of this class show individual components of a color and reflect the effect of changes to their values.

Constructor & Destructor Documentation

Slider::Slider (  mode  m = hue, QWidget *  parent = 0, const char *  name = 0, WFlags  f = 0 )

Constructs a Slider frame for use whith the mode m. The geometry for the Slider is derived from the currently used font geometry. Here is the call graph for this function:

Member Function Documentation

void Slider::colorChanged (  const rColor &   )  [signal]

void Slider::drawContents (  QPainter *  p  )  [protected]

Reimplemeted from QFrame. Additional to the background pixmap a white and a black triangle are displayed, denoting the current value for this Slider.

void Slider::mouseMoveEvent (  QMouseEvent *  e  )  [protected]

Updates the current position of the Slider while the mouse button is held down. Here is the call graph for this function:

void Slider::mousePressEvent (  QMouseEvent *  e  )  [protected]

Used if the slider should be gripped with the mouse. The Slider value will subsequently follow the horizontal mouse moves.

void Slider::mouseReleaseEvent (  QMouseEvent *  e  )  [protected]

This event stops the movement of the Slider, if it ever began. In any case the Slider is set to the value given by the position of the mouse pointer at the time of the click. Too complicated? Try this: You clicked it, you got it. Here is the call graph for this function:

void Slider::setColor (  const rColor &  nc  )

This sets the color, for which the slider will influence a component. A background pixmap is calculated based on the minimal and maximal values for this component. Here is the call graph for this function:

void Slider::setValue (  int  n  )  [inline]

Updates the current value of the Slider tobe n.

void Slider::useVal (  int  z  )  [private]

Updates the current color according to the value that changed. Emits a signal with the new color as argument. Here is the call graph for this function:
