Qt global-shortcut class
- supports Qt5.0 later.
- supports Windows and X11. (I don't have Mac.)
- not a library. (copy src/ to your project directly.)
- You can use this without any restriction.
add to your .pro like this
QT = core gui widgets
unix:QT = x11extras
unix:LIBS += -lX11 -lxcb
unix:QMAKE_CXXFLAGS += "-std=c++11"
HEADERS += \
src/qglobalshortcut.h
SOURCES += \
src/qglobalshortcut.cc
win32:SOURCES += src/qglobalshortcut_win.cc
unix:SOURCES += src/qglobalshortcut_x11.cc
#macx:SOURCES += src/qglobalshortcut_macx.cc
QGlobalShortcut class has some method like QShortcut class.
class QGlobalShortcut : public QObject {
public:
explicit QGlobalShortcut(QObject* parent = nullptr);
explicit QGlobalShortcut(const QKeySequence& keyseq, QObject* parent = nullptr);
QKeySequence key() const;
void setKey(const QKeySequence& keyseq);
signals:
void activated();
};use this as follows:
QGlobalShortcut gs;
gs.setKey(QKeySequence("Alt+Ctrl+Space"));
connect(&gs, SIGNAL(activated()), ...);
