如何处理GXT 2.2网格中单元格的点击？

Question

我正在寻找处理单元格单击的方式。如果我以这种方式在网格中创建新列，请执行此操作：

column = new ColumnConfig(); 
column.setId("remove"); 
column.setHeader("Remove"); 
column.setWidth(100);   
configs.add(column); 

？

Answer 1

您必须处理ColumnConfig所属网格上的单元格单击。 例如，假设你有Grid grid = new Grid(new ColumnModel(column));，则：

grid.addListener(Events.CellDoubleClick, new Listener<GridEvent>() { 
    public void handleEvent(GridEvent be) { 
     // be.getColIndex() gets the index of the column clicked on. 
     // if you know the index of `column`, you can compare that number to the colIndex 
     // if the numbers are equal, do whatever you want to do 
     // see docs for GridEvent at 
     // http://dev.sencha.com/deploy/gxt-2.2.5/docs/api/com/extjs/gxt/ui/client/event/GridEvent.html 
    } 
});
