Detailed Description

This class presents an editor modifying a real.

The decimal place can occur anywhere. Exponential notation is allowed.

Validation, consisting of a check that the contents are parsable as a number (using TLex::Val()) and a range check, is carried out when PrepareForFocusLossL is called. Invalid contents cause a leave of that method.

Value() only returns a value corresponding reliably to the value in the editor after a non-leaving call to PrepareForFocusLossL.

From resource constructor.

Refer to eikon.rh for the FLPTED resource structure

Parameters:
aReader Resource reader positioned at a FLPTED resource location

Reimplemented from CEikEdwin.

IMPORT_C void CEikFloatingPointEditor::ConstructL ( const TReal &  aMin,
const TReal &  aMax,
TInt  aTextLimit
) 
 

2nd stage constructor

IMPORT_C void CEikFloatingPointEditor::GetMinMax ( TReal &  aMin,
TReal &  aMax
)  const
 

Get minimum and maximum valid values.

Parameters:
aMin TReal& minimum value
aMax TReal& maximum value
IMPORT_C TValidationStatus CEikFloatingPointEditor::GetValueAsReal ( TReal &  aValue  ) 
 

Read out the value from the editor as a Real.

Returns:
Validation status of the current value
IMPORT_C void CEikFloatingPointEditor::HandlePointerEventL ( const TPointerEvent &  aPointerEvent  ) 
 

From CCoeControl.

Handles pointer events

Parameters:
aPointerEvent The pointer event.

Reimplemented from CAknNumericEdwin.

virtual IMPORT_C void CEikFloatingPointEditor::HandleResourceChange ( TInt  aType  )  [virtual]
 

Update contents of editor on certain resource change events.

Reimplemented from CEikEdwin.

virtual IMPORT_C TCoeInputCapabilities CEikFloatingPointEditor::InputCapabilities (   )  const [virtual]
 

Sets the input capabilities of the editor.

Reimplemented from CEikEdwin.

virtual IMPORT_C TKeyResponse CEikFloatingPointEditor::OfferKeyEventL ( const TKeyEvent &  aKeyEvent,
TEventCode  aType
)  [virtual]
 

Specific Key handling for numeric editor.

Reimplemented from CEikEdwin.

virtual IMPORT_C void CEikFloatingPointEditor::PrepareForFocusLossL (   )  [virtual]
 

Called by framework when focus is being taken off editor.

May be called by client code.

IMPORT_C void CEikFloatingPointEditor::SetMinMax ( TReal  aMin,
TReal  aMax
) 
 

Set minimum and maximum valid values.

Parameters:
aMin TInt minimum value
aMax TInt maximum value
IMPORT_C void CEikFloatingPointEditor::SetValueL ( const TReal *  aValue  ) 
 

Set the value in the editor.

Parameters:
aValue pointer to value to set
IMPORT_C TReal CEikFloatingPointEditor::Value (   )  const
 

Read out the value from the editor as a Real.

Value can only be relied on after a non-leaving call to PrepareForFocusLossL().

Returns:
Value in the editor
