Coding objects in GroupBox in a main layout

[kaiser0792]

I'm creating a Dialog for which I have created a main layout. I have added a 2D array of toolbuttons to the Dialog and next need to create a GroupBox that contains a few child widgets. To get the GroupBox to show up on the Dialog, I've had to add it to a SubLayout. But when I try to write code that places child widgets in the GroupBox, they show up outside the GroupBox. I have worked on this all day and have tried several variations suggested by the Qt Documentation examples. . Below is the code that I have written so far, it just attempts to add a QLabel to the GroupBox. Thanks for any help in advance.

@
#include "gamedialog.h"
#include <QtGui>

GameDialog::GameDialog(QWidget parent) :QDialog(parent)
{
// Create and configure layouts
QVBoxLayout mainLayout = new QVBoxLayout(this);
QGridLayout* gridLayout = new QGridLayout;
QVBoxLayout* groupBoxLayout = new QVBoxLayout;

mainLayout->addLayout(gridLayout);
mainLayout->addLayout(groupBoxLayout);
mainLayout->addStretch();

// Create grid of toolbuttons and add to layout
const int ROWS = 11;
const int COLUMNS = 21;

for(int i = 0; i < ROWS; i++)
        for(int j = 0; j < COLUMNS; j++)
        {
            toolButton = new QToolButton;
            gridLayout->addWidget(toolButton, i, j);
        }

groupBox = new QGroupBox("Simulation Configuration");
groupBoxLayout->addWidget(groupBox);
numStepsLabel = new QLabel("Number of Steps");
groupBoxLayout->addWidget(numStepsLabel);

Well, I'm not sure what you meant, but if you want your gridLayout (containing those toolbuttons) to be inside groupBox, shouldn't you put the gridLayout inside your groupBox? Something like this:

[code]
// Make grid
QGridLayout *gridLayout = ...

for(int i = 0; ...) ... gridLayout->addWidget(toolButton, i, j);

// Make groupbox and set layout
groupBox = new QGroupBox;
QVBoxLayout groupBoxLayout = new QVBoxLayout;
groupBox->setLayout(groupBoxLayout);

// Add things to groupbox (via layout)
groupBoxLayout->addLayout(gridLayout);
groupBoxLayout->addWidget(new QLabel);
[/code]

...And then put groupBox to dialog?

EDIT: I mean, it seems that you add your grid to main layout (line 12), and not in your groupbox's layout.
