qml 怎样修改window 窗口样式

Posted 2023-05-10

参考技术A 注册window窗口类，在qml里修改window属性就ok追问

能给个具体事例么？

追答

Qt Doc里面有一节叫 Using QML Bindings in C++ Applications，其中讲了关于这方面的内容，比如：你自己建了一个窗口类，然后自己注册下qmlRegisterType(...)，在qml中导入相应的版本的库，这样就可以在qml中实例化已注册的类鸟...

css代码怎样改变火狐浏览器中滚动条样式

　　CSS无法控制滚动条的样式。这里推荐几块滚动条美化的插件给你。
　　
1. Windows：全屏窗口滚动插件

　　该插件可以很好地实现全屏滚动，每滚动一次即为一屏。比如，用户浏览下一屏幕内容时，只需手动滚动到某一位置，该插件会自动滚动显示下一屏全部内容。对于浏览类似于PPT的内容时比较实用。

　　2. Jquery Scroll Follow：滚动跟随插件
　　该插件可以使DOM对象随着页面的滚动而移动。你可以设置滚动的速度、偏移等参数。

　　3. 列表滚动插件
　　该插件可以为任意列表添加上滚动效果。你可以自定义列表的滚动方向和滚动速度。

　　4. Sly：灵活的基于ITEM的滚动插件

　　SLY提供了很多基于项目（如图像/内容画廊）的滚动选项，支持水平和垂直方向的无限滚动。

5. Coverscroll

　　仿苹果的CoverFlow设计，支持滚动条、鼠标滚轮和手势来滚动查看。

6. Sticky
　该插件可以让你的页面中的任何元素在滚动过程中始终可见

7. Tiny Scrollbar：一个轻量级的JQUERY插件

8. Sticky Float：另一个滚动跟随插件

9. Page Scroller：漂亮实用的滚动导航

10. Custom Srollbar：自定义内容滚动条插件

11. Scroll Up：一个轻量级的滚动到顶部插件 参考技术A 可以直接在css文件中 获得标签名或者是ID 或者class 的名字 然后赋给它新的属性 后面使用!important 进行结束,这样子就可以覆盖原来的属性了. 也可以看下原来样式的选择的节点是什么,它有个优先级,ID>CLASS>标签名, 也可以直接写到滚动的标签的style属性里面,这样它的优先级会>id. 参考技术B css修改不了ff的滚动条的
不过你可以模拟一个
可以参考这个div滚动条
