Constructor & Destructor Documentation

KRootProp::KRootProp ( const QString rProp = QString::null  ) 

Constructs a KRootProp object for the property rProp.

Parameters:
rProp the property that will be searched, null to do nothing
See also:
setProp()

KRootProp::~KRootProp (  ) 

Destructs the KRootProp object.

Writes back any dirty configuration entries.


Member Function Documentation

void KRootProp::setProp ( const QString rProp = QString()  ) 

Sets the property in which keys will be searched.

Parameters:
rProp the property that will be searched

QString KRootProp::prop (  )  const

Returns the name of the property under which keys are searched.

Returns:
the property that will be searched

void KRootProp::destroy (  ) 

Destroys the property completely.

I.e. all entries will be cleared and the property will be removed from the root window.

QString KRootProp::readEntry ( const QString rKey,
const QString pDefault = QString::null 
) const

Reads the value of an entry specified by rKey in the current property.

Parameters:
rKey The key to search for.
pDefault A default value returned if the key was not found.
Returns:
The value for this key or the default if no value was found.

int KRootProp::readNumEntry ( const QString rKey,
int  nDefault = 0 
) const

Reads a numerical value.

Reads the value of an entry specified by rKey in the current property and interprets it numerically.

Parameters:
rKey The key to search for.
nDefault A default value returned if the key was not found.
Returns:
The value for this key or the default if no value was found.

QFont KRootProp::readFontEntry ( const QString rKey,
const QFont pDefault = 0 
) const

Reads a QFont value.

Reads the value of an entry specified by rKey in the current property and interpret it as a font object.

Parameters:
rKey The key to search for.
pDefault A default value returned if the key was not found.
Returns:
The value for this key or a default font if no value was found.

QColor KRootProp::readColorEntry ( const QString rKey,
const QColor pDefault = 0 
) const

Reads a QColor.

Reads the value of an entry specified by rKey in the current property and interprets it as a color.

Parameters:
rKey The key to search for.
pDefault A default value returned if the key was not found.
Returns:
The value for this key or a default color if no value was found.

QString KRootProp::writeEntry ( const QString rKey,
const QString rValue 
)

Writes a (key/value) pair.

This is stored to the current property when destroying the config object or when calling sync().

Parameters:
rKey The key to write.
rValue The value to write.
Returns:
The old value for this key. If this key did not exist, a null string is returned.

QString KRootProp::writeEntry ( const QString rKey,
int  nValue 
)

Writes the (key/value) pair.

Same as above, but writes a numerical value.

Parameters:
rKey The key to write.
nValue The value to write.
Returns:
The old value for this key. If this key did not exist, a null string is returned.

QString KRootProp::writeEntry ( const QString rKey,
const QFont rFont 
)

Writes the (key/value) pair.

Same as above, but writes a font.

Parameters:
rKey The key to write.
rFont The font to write.
Returns:
The old value for this key. If this key did not exist, a null string is returned.

QString KRootProp::writeEntry ( const QString rKey,
const QColor rColor 
)

Writes the (key/value) pair.

Same as above, but writes a color.

Parameters:
rKey The key to write.
rColor The color to write.
Returns:
The old value for this key. If this key did not exist, a null string is returned.

QString KRootProp::removeEntry ( const QString rKey  ) 

Removes an entry.

Parameters:
rKey The key to remove.
Returns:
The old value for this key. If this key did not exist, a null string is returned.

QStringList KRootProp::listEntries (  )  const

Returns a list of all keys.

Returns:
A QStringList containing all the keys.

void KRootProp::sync (  ) 

Flushes the entry cache.

Writes back dirty configuration entries to the current property, This is called automatically from the destructor.
