Finally, first English post.
I will teach you how to show basic window in PyQt5.
This is very basic post as well.
from PyQt5.QtWidgets import QMainWindow, QLabel, QApplication
class MainWindow(QMainWindow):
def __init__(self):
super().__init__()
self.__initUi()
def __initUi(self):
lbl = QLabel('Hello World!')
self.setCentralWidget(lbl)
if __name__ == "__main__":
import sys
app = QApplication(sys.argv)
w = MainWindow()
w.show()
app.exec_()
Super basic. But QLabel is little off from the center. Align it:
# know the drill, right?
//..
def __initUi(self):
lbl = QLabel('Hello World!')
lbl.setAlignment(Qt.AlignCenter)
self.setCentralWidget(lbl)
//..
So basic, only label? I don’t think this actually is capable of doing something.
At least he needs some friend to hang around with.
How about QTextEdit?
from PyQt5.QtWidgets import QMainWindow, QLabel, QApplication, QVBoxLayout, QTextEdit, QWidget
from PyQt5.QtCore import Qt
class MainWindow(QMainWindow):
def __init__(self):
super().__init__()
self.__initUi()
def __initUi(self):
lbl = QLabel('Hello Text Editor!')
lbl.setAlignment(Qt.AlignCenter)
te = QTextEdit() # new friend here!
lay = QVBoxLayout() # layout (layout is needed for 2 or more widgets)
lay.addWidget(lbl)
lay.addWidget(te)
mainWidget = QWidget() # we need widget to contain the layout
mainWidget.setLayout(lay)
self.setCentralWidget(mainWidget)
if __name__ == "__main__":
import sys
app = QApplication(sys.argv)
w = MainWindow()
w.show()
app.exec_()
Basic. What do you expect to my first English post?
This spent so much time than i expected. Just.. Wow.
How can anybody take the time to write down the post far longer than this?
