Member Function Documentation

virtual void CAknQueryValueTime::AppendValueIfNewL (   )  [protected, virtual]
 

Method to add the current value to the QueryValueArray if it is new.

The new value is not owned by QueryValue object, but is "given away"

Reimplemented from CAknQueryValue.

void CAknQueryValueTime::CalculateCurrentIndex (   )  [protected]
 

Search for the current time in the list, and set the curent index to be the found index.

If not found, set current index to 1 after the size of the array.

void CAknQueryValueTime::ConstructL (   )  [protected]
 

Two stage construction.

virtual IMPORT_C TBool CAknQueryValueTime::CreateEditorL (   )  [virtual]
 

Creates an editor within context.

If the value is edited and OK'd, the new value will be set as the current value. Otherwise the current value remains unchanged.

Returns:
ETrue if current value was altered; EFalse otherwise

Implements MAknQueryValue.

virtual IMPORT_C TInt CAknQueryValueTime::CurrentValueIndex (   )  const [virtual]
 

Returns the index in the array of the current value.

If no matches, returns zero

Implements MAknQueryValue.

virtual IMPORT_C HBufC* CAknQueryValueTime::CurrentValueTextLC (   )  [virtual]
 

This should be implemented so that it returns the current value as text.

Returns:
descriptor representing current value, new descriptor is created and left on cleanup stack, ownership passed back to client

Implements MAknQueryValue.

virtual IMPORT_C const MDesCArray* CAknQueryValueTime::MdcArray (   )  const [virtual]
 

Returns the array as a descriptor array, ownership will be not passed.

Implements MAknQueryValue.

static IMPORT_C CAknQueryValueTime* CAknQueryValueTime::NewL (   )  [static]
 

First stage of two stage construction.

static IMPORT_C CAknQueryValueTime* CAknQueryValueTime::NewLC (   )  [static]
 

First stage of two stage construction.

IMPORT_C void CAknQueryValueTime::SetArrayL ( const CAknQueryValueTimeArray *  aArray  ) 
 

Set the array.

Parameters:
aArray pointer to array, ownership is not passed
virtual IMPORT_C void CAknQueryValueTime::SetCurrentValueIndex ( const TInt  aIndex  )  [virtual]
 

Changes the current value to correspond to a value in the array.

Parameters:
aIndex index in array of value to set as current

Implements MAknQueryValue.

IMPORT_C void CAknQueryValueTime::SetQueryCaption ( TInt  aResourceId  ) 
 

Set the string used for the query caption to be a string other than the default.

Parameters:
aResourceId resource id of string to use for caption.
IMPORT_C TTime CAknQueryValueTime::Value (   )  const
 

Return the current value, which may have been set by the user.

Returns:
The current value
