nextcloud 移动数据位置
下面是官方说明： https://github.com/nextcloud/nextcloud-snap/wiki/Change-data-directory-to-use-another-disk-partition Removable media Also note that the interface providing the ability to access removable media is not automatically connected upon install, so if you’d like to use external storage (or otherwise use a device in /media for data), you need to give the snap permission to access removable media by connecting that interface: $ sudo snap connect nextcloud:removable-media 可以使用 mount –bind 命令挂载已有目录。要实现自动挂载，可以写在 /etc/fstab 里面。

加快QWebview中执行Javascript的速度
The issue is that Qt is evaluating the return value of the last statement in Javascript and converting it to a QVariant. It became time consuming because jQuery was returning the jQuery object, which was being evaluated in its entirety by Qt - and recursively at that. This also consumed RAM too. It wasn’t console.log that was fixing the issue, it was the “null” value it returned. I tested, and stapling “null” at the end of the script also worked.
Below is the updated code.
1 | myWebElement->evaluateJavaScript( myScript + "; null" ); |
如果发现执行速度超级慢，按上面的方法处理。
QWizard不能显示完成与取消按钮的问题
我使用的是Qt5.4.2, 遇到这个问题。对话框显示出来后，用鼠标改变一下大小就能显示出来。看起来像Qt的bug。 经反复尝试，发现修改QWizard的属性styleSheet为ClassicStyle就可以解决这个问题。 具体原因不清楚。
