resizing child window with parent window

[sujan.dasmahapatra]

Please give me some idea on resizing the child window. I have parent widget, when resizing this parent widget, I want all my other child widgets should also resize accordingly.

I have tried with QFormLayout, with formlayout, the widget’s size is changing, e.g a pushbutton is coming horizontally as long as the parent widget, although I am specifying a size for 100,25 width and height.

Please give me some suggestion. Check this snippet.

MainWindow::MainWindow(QWidget *parent):QMainWindow(parent)
{
   setGeometry(0,0,600,400);
   QPushButton *button = new QPushButton(“Add chart”, this);
   button->setGeometry(5,5,100,25);
   button->show();
 
  QTextEdit *edit = new QTextEdit(this);
  edit->setGeometry(5, 35, width()-10, height()-40);
  edit->show();
}

MainWindow::MainWindow(QWidget *parent):QMainWindow(parent)
{
   setGeometry(0,0,600,400);
   QPushButton *button = new QPushButton(“Add chart”, this);
   button->setGeometry(5,5,100,25);
   button->show();

  QTextEdit *edit = new QTextEdit(this);
  edit->setGeometry(5, 35, width()-10, height()-40);
  edit->show();
}

To copy to clipboard, switch view to plain text mode 

This 2 controls are set on the widget, now when I resize to the full screen, the textedit size is not changing accordingly, please help what I can do for this. Thanks Sujan

Use a layout.

MainWindow::MainWindow(QWidget *parent):QMainWindow(parent)
{
   setGeometry(0,0,600,400);
   QPushButton *button = new QPushButton(“Add chart”, this);
   button->setGeometry(5,5,100,25);
   button->show();
 
  QTextEdit *edit = new QTextEdit(this);
  edit->setGeometry(5, 35, width()-10, height()-40);
  edit->show();
 
  QFormLayout *formL = new QFormLayout(this);
  formL->addWidget(edit);
  setLayout(formL);
 
}

MainWindow::MainWindow(QWidget *parent):QMainWindow(parent)
{
   setGeometry(0,0,600,400);
   QPushButton *button = new QPushButton(“Add chart”, this);
   button->setGeometry(5,5,100,25);
   button->show();

  QTextEdit *edit = new QTextEdit(this);
  edit->setGeometry(5, 35, width()-10, height()-40);
  edit->show();

  QFormLayout *formL = new QFormLayout(this);
  formL->addWidget(edit);
  setLayout(formL);

}
