GXT EditorGrid：逐单元格选择单元编辑器类型

问题描述

GXT EditorGrid提供了一种机制来设置列的编辑器类型。

有没有在单元格的基础上定义编辑器类型？ p>

对于好奇心：

我需要创建一个转置的表;列成为行，行是列。在这种情况下，列（从普通表的角度）将具有各种编辑器类型，由此一行将具有相同的编辑器类型。

解决方案

基本上，你必须处理BeforeEdit事件并设置编辑器。这是一个可以从中实现网格的基类：

  public abstract class AnyEditorGrid< T extends ModelData>扩展EditorGrid< T> {
 
 public AnyEditorGrid（final ListStore< T> listStore，final ColumnModel columnModel）{
 super（listStore，columnModel）; 
 addListener（Events.BeforeEdit，new Listener< GridEvent< T>（）{
 @Override 
 public void handleEvent（final GridEvent< T> be）{
 final CellEditor编辑器= getEditor（be.getRowIndex（），be.getColIndex（），be.getModel（））; 
 if（editor！= null）{
 getColumnModel（）setEditor（be.getColIndex ，编辑）; 
} else {
 be.setCancelled（true）; 
} 
} 
}）; 
} 
 
保护抽象CellEditor getEditor（int rowIndex，int colIndex，T model）; 
 
} 
  

GXT EditorGrid provide a mechanism to set a type of editor for a column.

Is there anyway to define the editor type on a cell by cell basis?

For the curious minds:

I need to create a transposed table; the column become the row and the row is the column. That being the case, a column (from a normal table point of view) will have various editor type, whereby a row will have identical editor type.

解决方案

basically, you have to handle the BeforeEdit event and set the editor. Here is a base class from which you can implement your grid:

public abstract class AnyEditorGrid<T extends ModelData> extends EditorGrid<T> {

    public AnyEditorGrid(final ListStore<T> listStore, final ColumnModel columnModel) {
        super(listStore, columnModel);
        addListener(Events.BeforeEdit, new Listener<GridEvent<T>>() {
            @Override
            public void handleEvent(final GridEvent<T> be) {
                final CellEditor editor = getEditor(be.getRowIndex(), be.getColIndex(), be.getModel());
                if (editor != null) {
                    getColumnModel().setEditor(be.getColIndex(), editor);
                } else {
                    be.setCancelled(true);
                }
            }
        });
    }

    protected abstract CellEditor getEditor(int rowIndex, int colIndex, T model);

}
