Qt5 global hotkey-qxtglobalshortcut

Recently, you need to register a global hot key for a project. You can find a third-party library libqxt on the Internet to provide a better cross-platform solution, that is, qxtglobalshortcut.

However, during the compilation process, we found that the qiniacteventdispatcher: eventfilter used in this library is no longer in qt5.3.1, so I changed it myself.

The changes are as follows:

Add the following code before the qxtglobalshortcutprivate class, because the qiniactnativeeventfilter class needs to be used in qt5.

1 #if(QT_VERSION>=0x050000)2 #include <QAbstractNativeEventFilter>3 #endif

 

Then

class QxtGlobalShortcutPrivate : public QxtPrivate<QxtGlobalShortcut>

Change

1 class QxtGlobalShortcutPrivate : public QxtPrivate<QxtGlobalShortcut>2 #if(QT_VERSION>=0x050000)3         , public QAbstractNativeEventFilter4 #endif

Add

1 static QAbstractEventDispatcher::EventFilter prevEventFilter;2     static bool eventFilter(void* message);

Change

1 #if(QT_VERSION<0x050000)2     static QAbstractEventDispatcher::EventFilter prevEventFilter;3     static bool eventFilter(void* message);4 #else5     bool nativeEventFilter(const QByteArray &eventType, void *message, long *result);6 #endif

Then, in qxtglobalshortcut_mac.cpp, qxtglobalshortcut_win.cpp, and qxtglobalshortcut_x11.cpp

 

bool QxtGlobalShortcutPrivate::eventFilter(void* message)

 

The function is implemented as follows:

1 # If (qt_version <0x050000) 2 bool qxtglobalshortcutprivate: eventfilter (void * message) 3 {4 code in the original function; 5} 6 # else 7 bool qxtglobalshortcutprivate :: nativeeventfilter (const qbytearray &, void * message, long *) 8 {9 same as the code in the eventfilter function 10} 11 # endif

After this modification, it can be used on qt5.3.1 without affecting the use of the original qt4.
