问题描述
我如何正确证明PyQt5中的QKeySequence?
How I can right justify the QKeySequence in PyQt5?
copy_absolute_path_action = (
create_action(self, _("Copy Absolute Path"), QKeySequence(
get_shortcut('explorer', 'copy absolute path')),
triggered=self.copy_absolute_path))
copy_relative_path_action = (
create_action(self, _("Copy Relative Path"), QKeySequence(
get_shortcut('explorer', 'copy relative path')),
triggered=self.copy_relative_path))
copy_file_clipboard_action = (
create_action(self, _("Copy File to Clipboard"),
QKeySequence(get_shortcut('explorer', 'copy file')),
icon=ima.icon('editcopy'),
triggered=self.copy_file_clipboard))
save_file_clipboard_action = (
create_action(self, _("Paste File from Clipboard"),
QKeySequence(get_shortcut('explorer', 'paste file')),
icon=ima.icon('editpaste'),
triggered=self.save_file_clipboard))
我希望对快捷键进行合理调整,而其余的保持不变.
I want the key shortcuts to be right justified and the rest unchanged.
预先感谢
推荐答案
在这种情况下,解决方案是实现QProxyStyle:
In this case the solution is to implement a QProxyStyle:
from PyQt5 import QtCore, QtGui, QtWidgets
class MenuProxyStyle(QtWidgets.QProxyStyle):
def drawControl(self, element, option, painter, widget=None):
shortcut = ""
if element == QtWidgets.QStyle.CE_MenuItem:
vals = option.text.split("\t")
if len(vals) == 2:
text, shortcut = vals
option.text = text
super(MenuProxyStyle, self).drawControl(element, option, painter, widget)
if shortcut:
margin = 10 # QStyleHelper::dpiScaled(5)
self.proxy().drawItemText(painter, option.rect.adjusted(margin, 0, -margin, 0),
QtCore.Qt.AlignRight | QtCore.Qt.AlignVCenter,
option.palette, option.state & QtWidgets.QStyle.State_Enabled,
shortcut, QtGui.QPalette.Text)
class MainWindow(QtWidgets.QMainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
menu = QtWidgets.QMenu("File", self)
self._proxy = MenuProxyStyle(menu.style())
menu.setStyle(self._proxy)
self.menuBar().addMenu(menu)
# create icons
data = [("Copy Absolute Path", "Ctrl+Alt+C"),
("Copy Relative Path", "Ctrl+Shift+C"),
("Copy File to Clipboard", "Ctrl+C")]
for text, shortcut in data:
action = QtWidgets.QAction(self,
text=text,
shortcut=QtGui.QKeySequence(shortcut))
menu.addAction(action)
if __name__ == '__main__':
import sys
app = QtWidgets.QApplication(sys.argv)
w = MainWindow()
w.resize(640, 480)
w.show()
sys.exit(app.exec_())
