自定义ext js grid / accordion中的展开/折叠按钮

Question

有没有办法在ExtJs grid / accordion中自定义展开（+）/折叠（ - ）按钮。

Answer 1

您可以通过覆盖工具图标的CSS来更改图标。您可以将类名添加到accordion面板，并使用该样式将样式应用于工具按钮。

示例代码段

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,
.my-accordion .x-accordion-hd .x-tool-collapse-bottom {
  background-position: 0 -570px;
}

.my-accordion .x-accordion-hd .x-tool-over .x-tool-expand-top,
.my-accordion .x-accordion-hd .x-tool-over .x-tool-expand-bottom,
.my-accordion .x-accordion-hd .x-tool-expand-top,
.my-accordion .x-accordion-hd .x-tool-expand-bottom {
  background-position: 0 525px;
