如何将鼠标悬停事件添加到EXTJS中的fieldset？

For the below code snippet, I want to add a mouse hover event such that on mouse over, background color of fieldset item changes and an image is display next to the fieldset item

对于下面的代码片段,我想添加鼠标悬停事件,以便在鼠标悬停时,字段集项目的背景颜色发生变化,图像显示在字段集项目旁边

 var mainGroup = {
                           xtype: 'fieldset',
                           margin: '0 40 0 40',
                           border: true,
                           title: '<html><h3>' + displayLabel + '</h3></html>',
                           defaults: {
                           anchor: '100%',
                           padding: 3,
                           width: '80%',
                           },
                           layout:'hbox',
                           items: []
            };

Please help me in this regard.

Add this to your fieldset configs:

将其添加到您的fieldset配置:

listeners: {
    render: function () {
        this.getEl().on('mouseover', function () {
            alert('Mouse over!'); 
            //logic of whatever you want happening...
        });
    }
}

I would also look into mouseenter, if you don't want the logic to be executed every time the user moves the mouse just even slightly within the fieldset.

如果你不希望每次用户在字段集中稍微移动鼠标时执行逻辑,我也会调查mouseenter。
