完整的SWT示例：可编辑的table

1、完整的SWT示例：可编辑的table在项目开发时用到了table，但是想直接编辑表格中的内容，但是SWTTable是不支持直接编辑功能的，查阅了相关资料后，利用TableEdior实现了可编辑的Table，代码如下：importorg.eclipse.swt.SWT;importorg.eclipse.swt.custom.TableEditor;importorg.eclipse.swt.events.FocusAdapter;importorg.eclipse.swt.events.FocusEvent;importorg.eclipse.swt.events.ModifyEvent;im

2、portorg.eclipse.swt.events.ModifyListener;importorg.eclipse.swt.graphics.Point;importorg.eclipse.swt.graphics.Rectangle;importorg.eclipse.swt.layout.GridData;importorg.eclipse.swt.layout.GridLayout;importorg.eclipse.swt.widgets.Control;importorg.eclipse.swt.widgets.Display;importorg.eclipse.swt.widg

5、erVisible(true);table.setLinesVisible(true);table.setItemCount(ITEM_COUNT);table.setLayoutData(newGridData(SWT.FILL,SWT.FILL,true,true);TableColumncolumns=newTableColumnCOLUMN_COUNT;for(inti=0;iCOLUMN_COUNT;i+)columnsi=newTableColumn(table,SWT.CENTER);columnsi.setText(Column+newInteger(i+1).toString

6、();columnsi.setWidth(COLUMN_WIDTH);/监听对table的双击事件，执行可编辑操作table.addListener(SWT.MouseDoubleClick,listener);shell.open();while(!shell.isDisposed()if(!display.readAndDispatch()display.sleep();shell.dispose();display.dispose();/为每个Tableltem增加Listener,当有Selection事件时，根据行和列可以定位到每一个Cell,然后就可以处理事件，/为一个Cell添加

7、可编辑的方法是增加一个TableEditorprivateListenerlistener=newListener()privateintEDITABLECOLUMN;OverridepublicvoidhandleEvent(Eventevent)/获取鼠标点击的位置Pointpoint=newPoint(event.x,event.y);/得到鼠标点击的行(item)TableItemitem=table.getItem(point);if(item=null)return;for(inti=0;i4;i+)/得到选中行(item)的每一列的矩形范围，根据鼠标点击位置point来进一步确定

8、是哪一格(cell)Rectanglerect=item.getBounds(i);if(rect.contains(point)EDITABLECOLUMN=i;finalTableEditoreditor=newTableEditor(table);ControloldEditor=editor.getEditor();if(oldEditor!=null)oldEditor.dispose();/添加Text，并使高度符合item的高度finalTexttext=newText(table,SWT.NONE);puteSize(SWT.DEFAULT,table.getItemHeigh

9、t();/调整editor的高度宽度editor.grabHorizontal=true;editor.minimumHeight=text.getSize().y;editor.minimumWidth=text.getSize().x;editor.setEditor(text,item,EDITABLECOLUMN);text.setText(item.getText(EDITABLECOLUMN);text.forceFocus();/开始编辑的事件text.addModifyListener(newModifyListener()OverridepublicvoidmodifyText(ModifyEvente)text.setForeground(display.getSystemColor(SWT.COLOR_RED);editor.getItem().setText(EDITABLECOLUMN,text.getText(););/编辑后内容恢复表格前景色text.addFocusListener(newFocusAdapter()OverridepublicvoidfocusLos
