jsf - How to add double click listener to primefaces datatable

Question

What i want to do is; when user clicks to row, it will select the row.When user double clicks to row, it will start cell editing. At Primefaces showcase(http://www.primefaces.org/showcase/ui/d ... nstant.jsf) it says "Instant row selection, dblclick selection and unselection is implemented using ajax behaviors." but i couldnt find where they implemented dblclick selection. Is there a way to start cell editing event with double click event?

Answer 2

利用

<p:ajax event="rowDblselect" />

在你<p:dataTable />这样：

<p:dataTable 
    id="yourTableId" 
    value="#{yourBean.items}" 
    selectionMode="single" 
    selection="#{yourBean.selectedItem}" 
    var="item" 
    rowKey="#{item.id}">

    <p:ajax 
        event="rowDblselect" 
        listener="#{yourBean.onRowDoubleClick}" 
        update="@form:theComponentYouWantToUpdate" 
        global="false" />

    <!-- your columns here -->

</p:dataTable>

在您的 bean/控制器中使用：

import org.primefaces.event.SelectEvent;

public void onRowDoubleClick(final SelectEvent event) {
    YourObject obj = (YourObject) event.getObject();
    // rest of your logic
}

试着dblClickSelect="true"放在你的桌子上。

从文档中：

默认情况下，单击事件启用基于行的选择，启用 dblClickSelect 以便在行上双击进行选择。
