extjs750 window标题工具按钮图标不显示异常处理

版本

extjs7.x classic material主题

效果

修正前，window标题中关闭图标可见，tools图标看不见

修正后，tools正常显示图标

原因

检查元素发现图标样式继承了neutral主题.x-tool-tool-el样式的颜色，查阅源码可知material继承neutral主题却没有为window的tools定义样式

解决

自定义样式

.#{$prefix}window {
  .#{$prefix}window-header {
    .#{$prefix}tool-tool-el {
      color: $base-color;
    }
    .#{$prefix}tool-close {
      color: $window-close-glyph-color;
    }
  }
}
