Q_OS_IOS:表示iOS操作系统。 区别: QWS主要用于表示窗口系统,而QOS用于表示操作系统。 QWS只能表示窗口系统,而QOS可以表示更广泛的操作系统。 QWS的取值范围较小,而QOS的取值范围更广泛。 在Qt中,可以使用这些宏来编写跨平台的代码,根据不同的窗口系统和操作系统执行不同的操作。例如,可以使用Q_WS_WIN宏来编写只...

I used Homebrew to install qt4 in the past. I uninstalled qt4, installed qt5 and tried building with cmake; Error posted below: CMake Warning at CMakeLists.txt:97 (FIND_PACKAGE): By not providing "FindQt5Widgets.cmake" in CMAKE_MODULE_PA...
在每个平台上,Qt都为QWidget提供了一个winId()函数,返回window ID或是句柄;QWidget还提供了一个静态函数find(),返回一个特定window ID对应的widget。我们可以将获得的window ID传递给Native API来执行平台特定的操作。 Qt定义了以下系统标志:Q_WS_WIN,Q_WS_X11,Q_WS_MAC,Q_WS_QWS(Qtopia)。 QSysInfo::Wi...

比如:Qt中Gui部件的核心类QWidget,该类除了qwidget.h 和 qwidget.cpp两个原文件外,还有 kernel/qwidget_mac.mmkernel/qwidget_qws.cppkernel/qwidget_win.cppkernel/qwidget_s60.cppkernel/qwidget_x11.cppkernel/qwidget_wince.cpp …在源代码中, #if defined(Q_WS_X11) ... #elif defined(Q_WS_MAC...
In Qt 5, the Q_WS_* macros have been removed, so any code wrapped in them will never be compiled. Where appropriate (ie when code being wrapped is operating system specific and not window system specific), such code can and should be ported to the Q_OS_* macros. ...
For example, on Linux, you'll find Q_OS_LINUX and probably Q_WS_X11. When you know on which system you are running, you can access all X11 events by re-implementing the x11EventFilter function of the QApplication class. On OS X, you can get hold of the CoreGraphics handle from ...
template <typename T> class QList; class QLocale; #if defined(Q_WS_QWS) class QDecoration; #endif class QApplication; class QApplicationPrivate; 模板类的前向声明还是头一次见到:template <typename T> class QList;现在不会用……以后研究,看样子Qt的源码真的非常复杂哦。
