编译器没有看到QX11Info [英] Compiler does not see QX11Info

问题描述

我创建了一个类来设置一些全局快捷方式。
现在，当我编译我的应用程序，我看到许多错误：

I've created a little class to set some global shortcuts. But now, when i compile my app i see many errors:

In file included from ../src/GlobalShortcut/globalshortcut_linux.h:7:0,
                 from moc_globalshortcut_linux.cpp:9:
../../../QtStable/5.4/gcc_64/include/QtWidgets/qstyleoption.h:117:9: error: expected identifier before numeric constant
         None = 0x00,
         ^

                 from moc_globalshortcut_linux.cpp:9:

     Q_DECLARE_FLAGS(FrameFeatures, FrameFeature)
                                    ^

当我评论我的类错误消失了。
这是它： http://pastebin.com/k5qSvqDn

When i commented my class errors are gone. Here is it: http://pastebin.com/k5qSvqDn

好吧，我从QWidget继承类，而不是QMainWindow（我不知道为什么：D），现在我有另一个错误：

Ok, i inherited class from QWidget instead of QMainWindow (i dont know why :D) and now i have another errors:

mainwindow.o: In function `X11ShortCut::addShortCut(QKeySequence, QString)':
globalshortcut_linux.h:30: undefined reference to `QX11Info::display()'
globalshortcut_linux.h:31: undefined reference to `QX11Info::appRootWindow(int)'
globalshortcut_linux.h:31: undefined reference to `QX11Info::display()'
globalshortcut_linux.h:32: undefined reference to `QX11Info::display()'

在我的.pro文件中添加了 LIBS + = -lX11 ，它没有帮助。

那么，问题是什么？

推荐答案

检查，但我相信你只是错过添加以下到您的 .pro 文件，如 docs

I have not checked, but I believe you only missed adding the following to your .pro file, as stated at the docs

QT += gui x11extras

这可能是你可能会丢失一个头文件，但没有错误信息，我觉得有点硬因为我从来没有触摸过X11的东西。

It's likely that that you may be missing a header file, but without the error message, I find it a bit hard to figure it out since I've never touched X11 stuff directly.

希望它有帮助。
