方法详细资料

getCellEditorValue

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

Returns the value contained in the editor.

返回:

the value contained in the editor

抛出:

java.lang.Exception

getCellEditorComponent

java.awt.Component getCellEditorComponent(Grid grid,
                                        TemplateCellElement cellElement,
                                        int resolution)

Sets an initial cellElement for the editor. This will cause the editor to stopCellEditing 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

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

resolution - the current screen resolution

getLocationOnCellElement

java.awt.Point getLocationOnCellElement()

Gets the location of this component in the form of a point specifying the component's top-left corner in the CellElement's coordinate space. The default value is (0, 0).

返回:

an instance of Point representing the top-left corner of the component's bounds in the coordinate space of the CellElement

setLocationOnCellElement

void setLocationOnCellElement(java.awt.Point loc)

Sets the location of this component in the form of a point specifying the component's top-left corner in the CellElement's coordinate space.

参数:

loc - an instance of Point representing the top-left corner of the component's bounds in the coordinate space of the CellElement

stopCellEditing

boolean stopCellEditing()

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

cancelCellEditing

void cancelCellEditing()

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

addCellEditorListener

void addCellEditorListener(CellEditorListener cellEditorListener)

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

参数:

cellEditorListener - the CellEditorListener

removeCellEditorListener

void removeCellEditorListener(CellEditorListener cellEditorListener)

Removes a listener from the list that's notified

参数:

cellEditorListener - the CellEditorListener
