extjs - 自定义 ext js grid/accordion 中的展开/折叠按钮

Question

有没有办法自定义 ExtJs 网格/ Accordion 中的展开(+)/折叠(-)按钮。

Answer 1

您可以通过覆盖工具图标的 CSS 来更改图标。您可以将类名称添加到 Accordion 面板，并使用它将样式应用到工具按钮。

示例代码片段

Ext.create('Ext.panel.Panel', {
  title: 'Accordion Layout',
  width: 200,
  height: 300,
  layout: {
    type: 'accordion'
  },
  cls: 'my-accordion',
  items: [{
    title: 'Panel 1',
    html: 'Panel content!'
  }, {
    title: 'Panel 2',
    html: 'Panel content!',
    collapsed: true
  }, {
    title: 'Panel 3',
    html: 'Panel content!',
    collapsed: true
  }],
  renderTo: Ext.get("container")
});

body {
  padding: 0px;
}

.my-accordion .x-accordion-hd .x-tool-over .x-tool-collapse-top,
.my-accordion .x-accordion-hd .x-tool-over .x-tool-collapse-bottom,
.my-accordion .x-accordion-hd .x-tool-collapse-top,
