1. 万能方法:安装5.15版本,定位到报错的函数,切换到源码头文件,可以看到对应提示字样 QT_DEPRECATED_X("Use sizeInBytes") 和新函数。按照这个提示类修改就没错,一些函数是从Qt5.7 5.9 5.10等版本新增加的,可能你的项目还用的Qt4的方法,但是Qt6以前都兼容这些旧方法,到了Qt6就彻底需要用新方法了。2. Qt6对...

从Qt4转到Qt5,有些类的方法已经废弃或者过时了,如果想要在Qt5中启用Qt4的方法,比如QHeadVew的setMovable,可以在你的pro或者pri文件中加上一行即可:DEFINES += QT_DISABLE_DEPRECATED_BEFORE=009:081-090Qt中的QColor对颜色封装的很完美,支持各种转换,比如rgb、hsb、cmy、hsl,对应的是toRgb、toHsv、toCmyk、...

IMHO deprecated stuff can be removed only when it's 1-to-1. Unfortunately, Qt's "support version window" (for the mentioned feature), i.e., 5.11 to 5.13, is narrower than ours, i.e., 5.5.1 to 5.13. qt: Replace obsolete functions of QDesktopWidget c6dd32d hebasto force-pushed th...
