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.

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

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
