pyqgis – Capturing CTRL+Key in KeyPressEvent for PyQGIS QgsMapTool

eventspyqgispyqt

I created a Line with help of QgsMapTool and I'm able to capture the single key in keyPressEvent like this:

class buildingEditTool(QgsMapToolEdit):

    def keyPressEvent(self, event):
        
        if event.key() == Qt.Key_Backspace:
            ''' Do Something'''

then for a key combination I tried

class buildingEditTool(QgsMapToolEdit):

    def keyPressEvent(self, event):
        
        if event.matchs(QKeySequence(ctrl+k)):
            ''' Do Something'''

but it did not work.

How do I capture combination keys in keyPressEvent?

QKeyEvent has a method modifiers(). You should use it.

def keyPressEvent(self, event):

    if event.modifiers() & Qt.ControlModifier:
        if event.key() == Qt.Key_R:
            print("Ctrl + R")

You can create a new dialog as a class, even in your main .py file.

class NewDialog(QtGui.QWidget):
  def __init__(self, parent):
    super(NewDialog, self).__init__(parent)

Than in your main class you can put function like that:

...
def open_new_dialog(self):
    self.nd = NewDialog(self)
    self.nd.show()
...

This function creates a new dialog and display it.

Now just create a connection in your main class init:

class Plugin:
    """QGIS Plugin Implementation."""
    def __init__(self, iface):
    ...
    self.dlg.button.connect(self.open_new_dialog)

Of course you can do it on a different way. Ex. you can create self.nd = NewDialog(self) in main class in init and only self.nd.show() it in this function. And remember about passing objects like parent (it is your main dialog window) and iface if you want to use them with this new window.
