Inheritance diagram for KXYSelector:

QWidget KHSSelector List of all members.

Detailed Description

KXYSelector is the base class for other widgets which provides the ability to choose from a two-dimensional range of values.

The currently chosen value is indicated by a cross. An example is the KHSSelector which allows to choose from a range of colors, and which is used in KColorDialog.

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

Returns:
the rectangle on which subclasses should draw.

Definition at line 99 of file kselect.cpp.

void KXYSelector::drawContents ( QPainter  )  [protected, virtual]

Override this function to draw the contents of the widget.

The default implementation does nothing.

Draw within contentsRect() only.

Reimplemented in KHSSelector.

void KXYSelector::drawCursor ( QPainter p,
int  xp,
int  yp 
) [protected, virtual]

Override this function to draw the cursor which indicates the currently selected value pair.

Definition at line 221 of file kselect.cpp.

void KXYSelector::setRange ( int  minX,
int  minY,
int  maxX,
int  maxY 
)

Sets the range of possible values.

Definition at line 54 of file kselect.cpp.

void KXYSelector::setValues ( int  xPos,
int  yPos 
)

Sets the current values in horizontal and vertical direction.

Parameters:
xPos the horizontal value
yPos the veritcal value

Definition at line 75 of file kselect.cpp.

void KXYSelector::setXValue ( int  xPos  ) 

Sets the current horizontal value.

Parameters:
xPos the horizontal value

Definition at line 65 of file kselect.cpp.

void KXYSelector::setYValue ( int  yPos  ) 

Sets the current vertical value.

Parameters:
yPos the veritcal value

Definition at line 70 of file kselect.cpp.

void KXYSelector::valueChanged ( int  x,
int  y 
) [signal]

This signal is emitted whenever the user chooses a value, e.g.

by clicking with the mouse on the widget.

void KXYSelector::valuesFromPosition ( int  x,
int  y,
int &  xVal,
int &  yVal 
) const [protected]

Converts a pixel position to its corresponding values.

Definition at line 171 of file kselect.cpp.

int KXYSelector::xValue (  )  const [inline]

Returns:
the current value in horizontal direction.
