Detailed Description

Access KDE desktop resources stored on the root window.

A companion to the KConfig class.

The KRootProp class is used for reading and writing configuration entries to properties on the root window.

All configuration entries are of the form "key=value".

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

Construct a KRootProp object for the property rProp.

~KRootProp ()

Destructor.

Writes back any dirty configuration entries.

void setProp (const QString& rProp="")

Specify the property in which keys will be searched.

QString prop ()
[const]

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

void destroy ()

Destroy the property completely.

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

QString readEntry ( const QString& rKey, const QString& pDefault = QString::null )
[const]

Read the value of an entry specified by rKey in the current property

Parameters:
rKeyThe key to search for.
pDefaultA default value returned if the key was not found.

Returns: The value for this key or the default if no value was found.

int readNumEntry ( const QString& rKey, int nDefault = 0 )
[const]

Read a numerical value.

Read the value of an entry specified by rKey in the current property and interpret it numerically.

Parameters:
rKeyThe key to search for.
nDefaultA default value returned if the key was not found.

Returns: The value for this key or the default if no value was found.

QFont readFontEntry ( const QString& rKey, const QFont* pDefault = 0 )
[const]

Read a QFont.

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

Parameters:
rKeyThe key to search for.
pDefaultA 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 readColorEntry ( const QString& rKey, const QColor* pDefault = 0 )
[const]

Read a QColor.

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

Parameters:
rKeyThe key to search for.
pDefaultA 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 writeEntry ( const QString& rKey, const QString& rValue )

writeEntry() overridden to accept a const QString& argument.

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

Parameters:
rKeyThe key to write.
rValueThe value to write.

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

QString writeEntry ( const QString& rKey, int nValue )

Write the key value pair. Same as above, but write a numerical value.

Parameters:
rKeyThe key to write.
nValueThe value to write.

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

QString writeEntry ( const QString& rKey, const QFont& rFont )

Write the key value pair. Same as above, but write a font.

Parameters:
rKeyThe key to write.
rValueThe value to write.

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

QString writeEntry ( const QString& rKey, const QColor& rColor )

Write the key value pair. Same as above, but write a color.

Parameters:
rKeyThe key to write.
rValueThe value to write.

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

QString removeEntry (const QString& rKey)

Remove an entry.

Parameters:
rKeyThe key to remove.

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

QStringList listEntries ()
[const]

Get a list of all keys.

Returns: A QStringList containing all the keys.

void sync ()

Flush the entry cache. Write back dirty configuration entries to the current property, This is called automatically from the destructor.
