RCP日期控件

1、版面调用

text_17 = new Text(composite_2, SWT.BORDER );

FormData fd_text_17 = new FormData();
fd_text_17.top = new FormAttachment(combo_4,0,SWT.TOP);
fd_text_17.bottom = new FormAttachment(combo_4,0,SWT.BOTTOM);
fd_text_17.left = new FormAttachment(label_23, 2);
fd_text_17.right = new FormAttachment(label_23, 146,SWT.RIGHT);
text_17.setLayoutData(fd_text_17);
//text_17.setEnabled(false);
text_17.addMouseListener(new MouseAdapter(){


@Override
public void mouseUp(MouseEvent e) {
// TODO Auto-generated method stub
super.mouseUp(e);
OpenDateToText.getDateToText(e, shell);
}

});

2、公共代码

public class OpenDateToText {

public static void getDateToText(MouseEvent e,Shell shell){
Text bt = (Text) e.widget;
Point er = bt.getLocation();
DateDialog dl = new DateDialog(shell);
int x = er.x+20;
int y = er.y+177; //定位
dl.open(x,y,bt.getText());
bt.setText(dl.selectedDate);
}

 }
