I have this code:
#!/usr/bin/env python3
from PyQt5.QtWidgets import *
import sys
class Window(QWidget):
def __init__(self):
QWidget.__init__(self)
layout = QGridLayout()
self.setLayout(layout)
label_1 = QLabel("label 1")
layout.addWidget(label_1, 0, 0)
label_2 = QLabel("label 2")
layout.addWidget(label_2, 0, 1)
label_3 = QLabel("label 3")
layout.addWidget(label_3, 1, 0)
app = QApplication(sys.argv)
screen = Window()
screen.show()
sys.exit(app.exec_())
I have this result:
but I need this:
How can I do it?
The fourth and fifth arguments of addWidget allow you to specify how many rows and columns to span:
label_3 = QLabel("label 3")
layout.addWidget(label_3, 1, 0, 1, 2)
This is the example code for layout the QLabel. It is PyQt4, but you can try with PyQt5 with small changes.
import sys
from PyQt4 import QtGui
class Window (QtGui.QWidget):
def __init__(self, parent=None):
super(Window, self).__init__(parent)
self.verticalLayout = QtGui.QVBoxLayout (self)
self.verticalLayout.setObjectName ('verticalLayout')
self.gridLayout = QtGui.QGridLayout()
self.gridLayout.setObjectName ('gridLayout')
self.label_1 = QtGui.QLabel(self)
self.label_1.setObjectName('label_1')
self.label_1.setText ('Label_1')
self.label_1.setStyleSheet('background-color: rgb(182, 182, 182);')
self.label_2 = QtGui.QLabel(self)
self.label_2.setObjectName('label_2')
self.label_2.setText ('Label_2')
self.label_2.setStyleSheet('background-color: rgb(182, 182, 182);')
self.label_3 = QtGui.QLabel(self)
self.label_3.setObjectName('label_3')
self.label_3.setText ('Label_3')
self.label_3.setStyleSheet('background-color: rgb(182, 182, 182);')
self.gridLayout.addWidget(self.label_1, 0, 0, 1, 1)
self.gridLayout.addWidget(self.label_2, 0, 1, 1, 1)
self.gridLayout.addWidget(self.label_3, 1, 0, 1, 2)
self.verticalLayout.addLayout(self.gridLayout)
self.resize(300, 100)
if __name__ == '__main__':
app = QtGui.QApplication(sys.argv)
w = Window()
w.show()
sys.exit(app.exec_())

I put three label in a window, however, the three labels only occupy small part of the window. Here is my code:
from PyQt5.QtWidgets import *
import sys
class ThreeDMPRWindow(QMainWindow):
def __init__(self, image=None):
super(ThreeDMPRWindow, self).__init__()
self.resize(800, 600)
widget = QWidget()
self.setCentralWidget(widget)
layout = QVBoxLayout()
layout.setContentsMargins(0, 0, 0, 0)
widget.setLayout(layout)
allLayout = QHBoxLayout()
layout1 = QVBoxLayout()
label1 = QLabel('label 1')
label1.setStyleSheet("background: rgb(255,0,0)")
layout1.addWidget(label1)
layout2 = QVBoxLayout()
label2 = QLabel('label 2')
label2.setStyleSheet("background: rgb(255,0,0)")
layout2.addWidget(label2)
layout3 = QVBoxLayout()
label3 = QLabel('label 3')
label3.setStyleSheet("background: rgb(255,0,0)")
layout3.addWidget(label3)
qlayout = QGridLayout()
qlayout.addLayout(layout1, 0, 0, 2, 1)
qlayout.addLayout(layout2, 0, 1, 1, 1)
qlayout.addLayout(layout3, 1, 1, 1, 1)
allLayout.addLayout(qlayout)
allLayout.addLayout(QVBoxLayout())
layout.addLayout(allLayout)
app = QApplication(sys.argv)
window = ThreeDMPRWindow()
window.show()
app.exec_()
If we annotate the code: allLayout.addLayout(QVBoxLayout()), the three labels would occupy the whole window. I don't know why this code makes such difference. But I can't remove the code allLayout.addLayout(QVBoxLayout()), because I need the new layout for some other widgets.
If you want to have a space where you can add other widgets then you must use QWidget instead of QVBoxLayout, and in that QWidget add the QVBoxLayout:
# ...
allLayout.addLayout(qlayout)
empty_widget = QWidget()
empty_widget.setContentsMargins(0, 0, 0, 0)
lay = QVBoxLayout(empty_widget)
allLayout.addWidget(empty_widget)
layout.addLayout(allLayout)
# ...
Output:
I'm trying to create a table that have a column inside a cell. Is there an easy way to implement this design to the table view I'm working with?
This is my code right now:
class ColumnsLayout(QWidget):
def __init__(self, parent=None):
super(ColumnsLayout, self).__init__(parent)
table_row = QTableWidget()
table_row.setColumnCount(3)
table_row.horizontalHeader().setVisible(False)
for x in range(0, 3):
table_row.horizontalHeader().setSectionResizeMode(x, QHeaderView.Stretch)
layout = QHBoxLayout()
layout.setContentsMargins(0, 0, 0, 0)
layout.setSpacing(0)
layout.addWidget(table_row)
self.setLayout(layout)
self.ui.fields_tableWidget.setCellWidget(self.current_default_total_row, 2, ColumnsLayout())
You can use setSpan() to join cells
from PySide2 import QtWidgets
class ColumnsLayout(QtWidgets.QWidget):
def __init__(self, parent=None):
super(ColumnsLayout, self).__init__(parent)
table_row = QtWidgets.QTableWidget(4, 3)
table_row.horizontalHeader().hide()
table_row.setSpan(0, 0, 1, 3)
for x in range(0, 3):
table_row.horizontalHeader().setSectionResizeMode(x, QtWidgets.QHeaderView.Stretch)
layout = QtWidgets.QHBoxLayout(self)
layout.setContentsMargins(0, 0, 0, 0)
layout.setSpacing(0)
layout.addWidget(table_row)

I'm trying to integrate a QMenubar in a QWidget in Pyside2 in Python3. It seems to be easier to integrate a QMenubar to a QMainWindow but I started the project with a QWidget and not a QMainWindow and this is why I would like to have a solution for a QWidget.
When I run the code, there is no error message but the menubar doesn't appear when I run the app. I checked that stackoveflow page but it didn't help me or I wasn't able to implement it.
