How to do that?

[conexion2000]

Here is sample:


So I would like to do something similar. As You can see there is some QGroupBox with 3 horizontal QLayouts in it. These layouts contains some widgets. And here appears my problem. How to put these layouts inside this groupbox. Setting QGroupBox as a parent doesn't seem to work, because debug functions say that QGroupBox already have a layout. When I do that in a "traditional way" (creating QLayout with QGroupBox as a parent) these widgets don't show in program.
Please help.

It simple release with Designer !
Where is your problem ?
I attch screenshot that i release in designer and also give you code that was generated form ui file...

Form1Layout = new QGridLayout( this, 1, 1, 11, 6, "Form1Layout"); 
 
    groupBox1 = new QGroupBox( this, "groupBox1" );
    groupBox1->setColumnLayout(0, Qt::Vertical );
    groupBox1->layout()->setSpacing( 6 );
    groupBox1->layout()->setMargin( 11 );
    groupBox1Layout = new QGridLayout( groupBox1->layout() );
    groupBox1Layout->setAlignment( Qt::AlignTop );
 
    layout1 = new QHBoxLayout( 0, 0, 6, "layout1"); 
 
    checkBox1 = new QCheckBox( groupBox1, "checkBox1" );
    layout1->addWidget( checkBox1 );
 
    textLabel1 = new QLabel( groupBox1, "textLabel1" );
    layout1->addWidget( textLabel1 );
 
    spinBox1 = new QSpinBox( groupBox1, "spinBox1" );
    layout1->addWidget( spinBox1 );
 
    groupBox1Layout->addLayout( layout1, 0, 0 );
 
    layout2 = new QHBoxLayout( 0, 0, 6, "layout2"); 
 
    checkBox1_2 = new QCheckBox( groupBox1, "checkBox1_2" );
    layout2->addWidget( checkBox1_2 );
 
    textLabel1_2 = new QLabel( groupBox1, "textLabel1_2" );
    layout2->addWidget( textLabel1_2 );
 
    spinBox1_2 = new QSpinBox( groupBox1, "spinBox1_2" );
    layout2->addWidget( spinBox1_2 );
 
    groupBox1Layout->addLayout( layout2, 1, 0 );
 
    layout3 = new QHBoxLayout( 0, 0, 6, "layout3"); 
 
    checkBox1_3 = new QCheckBox( groupBox1, "checkBox1_3" );
    layout3->addWidget( checkBox1_3 );

You must use QWidget::setLayout.

QHBoxLayout* lay1 = new QHBoxLayout;
lay1->addWidget(wgt1_1);
...
lay1->addWidget(wgt1_N);
 
..........
 
QHBoxLayout* layN = new QHBoxLayout;
layN->addWidget(wgtN_1);
...
layN->addWidget(wgtN_N);
 
QVBoxLayout* v = new QVBoxLayout;
v->addLayout(lay1);
...
v->addLayout(layN);
 
grpBox->setLayout(v)

QHBoxLayout* lay1 = new QHBoxLayout;
lay1->addWidget(wgt1_1);
...
lay1->addWidget(wgt1_N);

..........

QHBoxLayout* layN = new QHBoxLayout;
layN->addWidget(wgtN_1);
...
layN->addWidget(wgtN_N);

QVBoxLayout* v = new QVBoxLayout;
v->addLayout(lay1);
...
v->addLayout(layN);

grpBox->setLayout(v)

To copy to clipboard, switch view to plain text mode 

where wgtX_X are widget to add and grpBox are your QGroupBox.
