方法详细资料

getFloatEditorValue

java.lang.Object getFloatEditorValue()
                                     throws java.lang.Exception

Returns the value contained in the editor.

返回:

the value contained in the editor

抛出:

java.lang.Exception

getFloatEditorComponent

java.awt.Component getFloatEditorComponent(Grid grid,
                                         FloatElement floatElement,
                                         int resolution)

Sets an initial floatElement for the editor. This will cause the editor to stopFloatEditing and lose any partially edited value if the editor is editing when this method is called.

Returns the component that should be added to the client's Component hierarchy. Once installed in the client's hierarchy this component will then be able to draw and receive user input.

参数:

grid - the Grid that is asking the editor to edit; can be null

floatElement - the value of the FloatElement to be edited; it is up to the specific editor to interpret and draw the value.

acceptKeyEventToStartFloatEditing

boolean acceptKeyEventToStartFloatEditing(java.awt.event.KeyEvent evt)

Accept keyevent to start editing.

stopFloatEditing

boolean stopFloatEditing()

Tells the editor to stop editing and accept any partially edited value as the value of the editor. The editor returns false if editing was not stopped; this is useful for editors that validate and can not accept invalid entries.

返回:

true if editing was stopped; false otherwise

cancelFloatEditing

void cancelFloatEditing()

Tells the editor to cancel editing and not accept any partially edited value.

addFloatEditorListener

void addFloatEditorListener(FloatEditorListener floatEditorListener)

Adds a listener to the list that's notified when the editor stops, or cancels editing.

参数:

floatEditorListener - the FloatEditorListener

removeFloatEditorListener

void removeFloatEditorListener(FloatEditorListener floatEditorListener)

Removes a listener from the list that's notified

参数:

floatEditorListener - the FloatEditorListener
