[英]GXT checkbox in grid
I need to update the store when the checkbox in the grid cell changed its state: to add or to remove the value from store. 当网格单元格中的复选框改变其状态时,我需要更新商店:添加或从商店中删除值。 how to handle this event?
如何处理这个事件? BTW, I create the checkbox in grid in this way:
顺便说一句,我用这种方式在网格中创建了一个复选框:
column = new ColumnConfig();
column.setId("accepted");
column.setHeader("Accepted");
column.setWidth(55);
UPD2: Now I do the following: create checkboxes as firstly decided: UPD2:现在我执行以下操作:首先创建复选框:
CheckColumnConfig checkColumn = new CheckColumnConfig("accepted", "", 55);
CellEditor checkBoxEditor = new CellEditor(new CheckBox());
checkBoxEditor.setToolTip("If you click here server will consider this rule checking your messages");
checkColumn.setEditor(checkBoxEditor);
checkColumn.setHeader("apply");
configs.add(checkColumn);
than handle events in the grid like this: UPD3: 比如下处理网格中的事件: UPD3:
grid.addListener(Events.CellMouseUp, new Listener<GridEvent>() {
@Override
public void handleEvent(GridEvent be) {
PropertyItem item;
if (grid.getStore().getAt(be.getRowIndex()).isAccepted()){
item = new PropertyItem(val1, val2, val3, true);
} else {
item = new PropertyItem(val1, val2, val3, false);
}
store.update(item);
store.commitChanges();
saveProperties(store, customerId, toRemove);
}
});
this is the right way. 这是正确的方法。
According to the docs found here , you can add a listener to the CellEditor
's Complete
event. 根据此处找到的文档,您可以向
CellEditor
的Complete
事件添加侦听器。 In the Complete
event Listener
, perform whatever activity you need to accomplish. 在
Complete
事件Listener
,执行您需要完成的任何活动。
Update : Try the following 更新 :尝试以下操作
column.setRenderer(new GridCellRenderer() {
@Override
public Object render(ModelData model, String property, ColumnData config, int rowIndex, int colIndex, final ListStore store, Grid grid) {
CheckBox box = new CheckBox();
box.addListener(Events.Change, new Listener<FieldEvent>() {
@Override
public void handleEvent(FieldEvent be) {
st.commitChanges();
saveProperties(st, customerId, toRemove);
// I'm not sure what saveProperties is, but see if this works now.
// this event should DEFINITELY be fired when the checkbox is clicked
// so if it doesn't work, try changing how you do your code here
// maybe by doing model.set(property, (Boolean) be.getValue()); or something
}
});
return box;
}
});
