I am building a UI with QT designer and want buttons to perform different actions with different modifiers. So I thought I could call functions with dynamic string properties that would perform the action depending on the modifier.
If anyone knows a simpler way to do this I would appreciate it very much.
It looks like all you need to do is check QApplication.keyboardModifiers in your button handler, and select a different action as appropriate:
from PyQt4 import QtGui, QtCore class Window(QtGui.QWidget): def __init__(self): QtGui.QWidget.__init__(self) self.button = QtGui.QPushButton('Test', self) self.button.clicked.connect(self.handleButton) layout = QtGui.QVBoxLayout(self) layout.addWidget(self.button) def handleButton(self): modifiers = QtGui.QApplication.keyboardModifiers() if modifiers == QtCore.Qt.ShiftModifier: print('Shift+Click') elif modifiers == QtCore.Qt.ControlModifier: print('Control+Click') elif modifiers == (QtCore.Qt.ControlModifier | QtCore.Qt.ShiftModifier): print('Control+Shift+Click') else: print('Click') if __name__ == '__main__': import sys app = QtGui.QApplication(sys.argv) window = Window() window.show() sys.exit(app.exec_())
(NB: the various modifiers can be OR'd together in order to check for multi-key combinations).
This is late reply but this is the solution that I found.
I was trying to handle multiple keys pressed at the same time (e.g. A and W or W and D). The solution below works with multiple keys being pressed at the same time (including Ctrl, Shift, Alt, etc). I hope someone else can find it useful.
def keyPressEvent(self, event): self.firstrelease = True astr = "pressed: " + str(event.key()) self.keylist.append(astr) def keyReleaseEvent(self, event): if self.firstrelease == True: self.processmultikeys(self.keylist) self.firstrelease = False del self.keylist[-1] def processmultikeys(self,keyspressed): # your logic here print keyspressed
