【问题描述】：
我的PyQt5 GUI 有以下代码：
import sys
from PyQt5.QtWidgets import QApplication, QWidget, QCalendarWidget, QMainWindow, QGridLayout, QLayout, QTableWidget, QHeaderView, QLabel, QHBoxLayout, QVBoxLayout, QLineEdit, QComboBox
from PyQt5.QtCore import QDate, Qt
from datetime import date, datetime
class CalendarWindow(QMainWindow):
def __init__(self, parent=None):
super(CalendarWindow, self).__init__(parent)
self.setUpUI()
def setUpUI(self):
self.setGeometry(50, 50, 1200, 700)
# Labels
self.label_events = QLabel(self)
self.label_new_event = QLabel(self)
self.label_event_name = QLabel(self)
self.label_start_date = QLabel(self)
self.label_repeat = QLabel(self)
self.label_description = QLabel(self)
# Labels parameters
self.label_events.setAlignment(Qt.AlignCenter)
self.label_events.setText("Wydarzenia danego dnia:")
# self.label_new_event.setAlignment(Qt.AlignCenter)
self.label_new_event.setText("Dodaj event:")
self.label_event_name.setText("Nazwa eventu:")
self.label_start_date.setText("Data eventu:")
self.label_repeat.setText("Powtarzalność eventu:")
self.label_description.setText("Opis:")
# TextEdits
self.text_event_name = QLineEdit(self)
self.text_start_date = QLineEdit(self)
self.text_description = QLineEdit(self)
# TextEdits parameters
# ComboBoxes
self.combo_repeat = QComboBox(self)
# ComboBoxes parameters
self.combo_repeat.addItems(
["No", "Day", "Week", "Two weeks", "Month", "Half a year", "Year"])
# Widgets
self.setWindowTitle("Python Calendar App")
self.calendar_widget = QCalendarWidget(self)
# User date select event
self.calendar_widget.clicked[QDate].connect(self.dateChanged)
self.events_list_widget = QTableWidget(self)
self.events_list_widget.setColumnCount(5)
self.events_list_widget.setHorizontalHeaderLabels(
["ID", "Name", "Date", "Repetition", "Description"])
# Columns stretched and fit
self.events_list_widget.horizontalHeader().setSectionResizeMode(
QHeaderView.Stretch)
self.main_widget = QWidget(self)
self.main_layout = QGridLayout(self.main_widget)
self.main_layout.sizeConstraint = QLayout.SetDefaultConstraint
self.main_layout.addWidget(self.calendar_widget, 0, 0)
self.init_sublayouts()
self.main_layout.addLayout(self.sublayout_events, 0, 1)
self.main_layout.addLayout(self.sublayout_new_event, 0, 2)
self.main_layout.setColumnStretch(0, 1)
self.main_layout.setColumnStretch(1, 3)
self.main_layout.setColumnStretch(2, 2)
self.main_widget.setLayout(self.main_layout)
self.setCentralWidget(self.main_widget)
def init_sublayouts(self):
# Events sublayout
self.sublayout_events = QVBoxLayout()
self.sublayout_events.addWidget(self.label_events)
self.sublayout_events.addWidget(self.events_list_widget)
# New event sublayout
self.sublayout_new_event = QVBoxLayout()
self.sublayout_new_event.addWidget(self.label_new_event)
self.sublayout_new_event_grid = QGridLayout()
self.sublayout_new_event_grid.addWidget(self.label_event_name, 1, 0)
self.sublayout_new_event_grid.addWidget(self.text_event_name, 1, 1)
self.sublayout_new_event_grid.addWidget(self.label_start_date, 2, 0)
self.sublayout_new_event_grid.addWidget(self.text_start_date, 2, 1)
self.sublayout_new_event_grid.addWidget(self.label_repeat, 3, 0)
self.sublayout_new_event_grid.addWidget(self.combo_repeat, 3, 1)
self.sublayout_new_event_grid.addWidget(self.label_description, 4, 0)
self.sublayout_new_event_grid.addWidget(self.text_description, 4, 1)
self.sublayout_new_event.addLayout(self.sublayout_new_event_grid)
def dateChanged(self, qdate):
print("Date changed to:", self.getDaysEvents())
selected_date = self.getDaysEvents()
# self.events_list_widget.addItem(selected_date.strftime("%d/%m/%y"))
def getDaysEvents(self):
selected_date = self.calendar_widget.selectedDate()
return selected_date.toPyDate()
if __name__ == '__main__':
app = QApplication(sys.argv)
foo = CalendarWindow()
foo.show()
sys.exit(app.exec_())
当你启动它时，它看起来像这样：
我对第 3 列有疑问。我希望Dodaj event: 标签位于顶部，而那些带有标签的文本框位于其下方不远处。相关代码在init_sublayouts# New event sublayout注释下。我试图将这些文本框变成QGridLayout 和Dodaj event 和这个QGridLayout 到QVBoxLabout，但你看到发生了什么。我还尝试将我的QGridLayout 的每一行都设为单独的QHBoxLayout，结果几乎相同。有没有办法做到这一点？我在第 2 列中做了类似的事情，我在 QTableWidget 上堆叠了一个 QLabel，但在第 3 列中它似乎没有按预期工作。
