QPainterform the basis of Qt's painting system, Arthur.QPainteris used to perform drawing operations,QPaintDeviceis an abstraction of a two-dimensional space that can be painted on using aQPainter, andQPaintEngineprovides the interface that the painter uses to draw onto different...
The conversion uses the default locale, set by QLocale::setDefaultLocale(). If no default locale was specified, the "C" locale is used.If fillChar is '0' (the number 0, ASCII 48), this function will use the locale's zero to pad. For negative numbers, the zero padding will probably...

2. Conversion to UTF-8: When you call the `toUtf8()` function on a `QString` object, it converts the data from its UTF-16 internal representation to UTF-8. UTF-8 is a variable-width encoding that uses 1 to 4 bytes to represent characters. It’s widely used on the web and in...
3、Window-Viewport Conversion 窗口-视口转换 When drawing withQPainter, we specify points using logical coordinates which then are converted into the physical coordinates of the paint device. 当使用QPainter绘图时,我们使用逻辑坐标指定点,然后将其转换为绘制设备的物理坐标。
Qt打包发布,有很多办法,Qt5以后提供了打包工具windeployqt(linux上为linuxdeployqt,mac上为macdeployqt)可以很方便的将应用程序打包,使用下来发现也不是万能的,有时候会多打包一些没有依赖的文件,有时候又会忘记打包一些插件尤其是用了qml的情况下,而且不能识别第三方库,比如程序依赖ffmpeg,则对应的库需要自行拷贝,终...
Conversion Between QtScript and C++ Types QtScript will perform type conversion when a value needs to be converted from the script side to the C++ side or vice versa; for instance, when a C++ signal triggers a script function, when you access aQObjectproperty in script code, or when you ...
