如何處理GXT 2.2網格中單元格的點擊？

Question

我正在尋找處理單元格單擊的方式。如果我以這種方式在網格中創建新列，請執行此操作：

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

？

Answer 1

您必須處理ColumnConfig所屬網格上的單元格單擊。 例如，假設你有Grid grid = new Grid(new ColumnModel(column));，則：

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 
    } 
});
