Add layout inside QFrame()

Question

I am beginner in the PyQt5

in my application I need to make (buttons, line edit, labels ...) in QVBoxLayout then puts everything on QFrame.

My Question: Is It possible to make a layout (QHBoxLayout, QVBoxLayout, QFormeLayout ....) inside a QFrame ?

If possible, please tell me how to do .

Answer 1

Use a text editor or Qt Designer to create an .ui file. Here is a minimal example:

<widget class="QFrame" name="frame">
   <property name="geometry">
      <rect><x>60</x><y>40</y><width>160</width><height>100</height> 
</rect>
   </property>
   <layout class="QVBoxLayout" name="verticalLayout">
      <item><widget class="QPushButton" name="pushButton" /></item>
      <item><widget class="QLabel" name="label" /></item>
      <item><widget class="QLineEdit" name="lineEdit"/></item>
   </layout>
</widget>

It will look something like this:

Python example:

import sys
from PySide6.QtWidgets import QApplication, QWidget, QFrame, QLabel, QLineEdit, QPushButton, QVBoxLayout, QSpacerItem
app = QApplication(sys.argv)
window = QWidget()
window.setGeometry(300,300,300,100)
frame = QFrame(window)
layout = QVBoxLayout(frame)
pushButton = QPushButton("pushButton")
layout.addWidget(pushButton)
label = QLabel("label")
layout.addWidget(label)
lineEdit = QLineEdit("lineEdit")
layout.addWidget(lineEdit)
window.show()
app.exec()

C++ example:

void QtWidgetsApplication1::setupUi(QMainWindow* window) {
  
   frame = new QFrame(window);
   window->setCentralWidget(frame);

   verticalLayout = new QVBoxLayout(frame);

   pushButton = new QPushButton(frame);
   pushButton->setText("pushButton");
   verticalLayout->addWidget(pushButton);

   label = new QLabel(frame);
   label->setText("label");
   verticalLayout->addWidget(label);

   lineEdit = new QLineEdit(frame);
   lineEdit->setText("lineEdit");
   verticalLayout->addWidget(lineEdit);

   verticalSpacer = new QSpacerItem(20, 40, QSizePolicy::Minimum, QSizePolicy::Expanding);
   verticalLayout->addItem(verticalSpacer);
}
