Facing a strange problem with QTreeWidget
Message 1 in thread
Hello All
Greetings!!
Actually I am trying to create a simple tree widget inside a window which is
derived from QWidget class. But it is not getting displayed.
Can some body tell me what is the problem in the code below !!
Thanks a lot
Rohit
/***************************************************************************

#include "componentstree.h"
ComponentsTree::ComponentsTree(QWidget *parent)
{
addComponents();
}
ComponentsTree::~ComponentsTree ()
{
}
void ComponentsTree::addComponents()
{
QVBoxLayout *vLayout = new QVBoxLayout(this);
QHBoxLayout *hLayout = new QHBoxLayout();
treeWidget = new QTreeWidget(this);
treeWidget->setColumnCount(1);
vLayout->addLayout(hLayout);
vLayout->addWidget(treeWidget);
boolControl = new QTreeWidgetItem(treeWidget);
boolControl->setText(0,tr("Bool Control"));
setLayout(vLayout);
}

Try calling treeWidget->show() in your main() function, perhaps?

On second thoughts,
add "treeWidget->show()" after this line:
setLayout(vLayout);

Could I have a look at your main() function?

Try calling show() in addComponents() after the call
setLayout(vLayout), as below:
void ComponentsTree::addComponents()
{
.........
...............
setLayout(vLayout);
show();
}
