Hi guys!
I'm trying to add keyboard shortcuts to my application, but I'm stuck
at the beginning. Here is a simple application that I can't get to
work:
###
import sys
from PyQt4.Qt import Qt
from PyQt4.QtCore import QObject, SIGNAL
from PyQt4.QtGui import QWidget, QApplication, QMainWindow, QAction,
QIcon, QKeySequence
class MainWindow(QMainWindow):
def __init__(self, parent):
QMainWindow.__init__(self, parent)
self.centralwidget = QWidget(self)
self.action = QAction(QIcon(), "Down", self)
self.action.setShortcut("Ctrl+D")
self.action.setShortcutContext(Qt.ApplicationShortcut)
QObject.connect(self.action, SIGNAL("triggered()"), self.down)
def down(self):
print 'DOWN!!!'
def main():
app = QApplication(sys.argv)
mw = MainWindow(None)
mw.show()
sys.exit(app.exec_())
if __name__ == '__main__':
main()
###
I've tried using different shortcut context: WindowShortcut,
WidgetShortcut, ApplicationShortcut, but it still doesn't work.
Any help greately appreciated.
From the docs:
"Actions are added to widgets using QWidget::addAction(). Note that an
action must be added to a widget before it can be used; this is also
true when the shortcut should be global (i.e., Qt::ApplicationShortcut
as Qt::ShortcutContext)."
Add the line
self.addAction(self.action)
and it works.
