created a class which added to the project without ui.
I can't call it correctly.** the class I'm embedding: **

#include "oknonastroek.h" Widgets :: windowastroek :: windowastroek (QWidget * parent) : QWidget (parent) { } Widgets :: windowspawn :: ~ windowpattern () { } void Widgets :: oknonastroek :: razmer_element (int x, int y) { // set the size of the lines here _myTexpr.m_t_razm [0] = x / 60.0; // X indent _myTexpr.m_t_razm [1] = g / 4.0 + g / 60.0; // Y indent _myTexpr.m_t_razm [2] = x / 3.0; // width (window) x _myTexpr.m_t_razm [3] = g / 1.4; // height (window) y } void Widgets :: windowastroek :: paintEvent (QPaintEvent * event) { QPainter painter (this); // Create a renderer object QBrush bgfon (QColor (180,220,220), Qt :: SolidPattern); // set the background color and fill type (with background without background and fill type) painter.setPen (Qt :: NoPen); // paint brush if not needed painter.setRenderHint (QPainter :: Antialiasing); // remove sharp cubes painter.setBrush (bgfon); // set the background color razmer_element (this-> width (), this-> height ()); // set the size of the element painter.drawRect (_myTexpr.m_t_razm [0], _myTexpr.m_t_razm [1], _myTexpr.m_t_razm [2], _myTexpr.m_t_razm [3]); }** And here's the main class: **

here is the announcement
oknonastr = new Widgets :: oknonastroek (this);here is an update
oknonastr-> update ();if there was ui, then the file attached to the project, then the turquoise square would be beautifully displayed and so straight it is sad

~ windowspawn ();Typo or does your class c'tor have a different name than your d'tor?

OK, I explain in details:
When you don't use an UI from the Designer, you need to:
- set the central widget
- add a layout to the central widget
- add others widgets to the layout
QWidget* centralWidget= new QWidget; setCentralWidget(centralWidget); QBoxLayout* layout= new QVBoxLayout; centralWidget->setLayout(layout); layout->addWidget( *yourTurquoiseWidget*); -

mainLayout
You did not add this layout to any widget or other layout. Don't know how this can work...
