如何處理GXT 2.2網格中單元格上的單擊？

Question

我正在尋找處理單元格單擊的方法。 如果以這種方式在網格中創建新列，該如何做：

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

？

Answer 1

您必須處理ColumnConfig所屬的網格上的單元格單擊。 例如，假設您有Grid grid = new Grid(new ColumnModel(column)); ， 然后：

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
    }
});
