Layout issue

[sajis997]

Hello forum,

I am instantiating property widgets and arranging them in a layout with the click event dynamically.

I hope that the attached screen-shot gives you the idea. As you can see that the layout is not working
properly. The label "DEF" and the line edit arrangement is not aligning well with rest of the other properties.

I am also attaching the corresponding code snippet so that you can provide me some useful hint to get around
this issue.

void H3DNodePropertiesWidget::instantiateWidgets()
{
    setUpdatesEnabled(false);
 
    if(m_widgetState == NONE)
    {
        m_propertyWidget = new QWidget;
 
        QGridLayout *gridLayout = new QGridLayout(m_propertyWidget);
        gridLayout->setContentsMargins(3,4,0,2);
        gridLayout->setSpacing(2);
        gridLayout->setColumnStretch(1,2);
 
 
        m_mainLayout->addWidget(m_propertyWidget);
 
        setUpdatesEnabled(true);
        updateState();
        m_widgetFactory = 0;
 
        m_widgetState = ONLY_TF;
 
    }
    //THIS FOLLOWING CONDITION IS THE RESPOONSIBLE FOR CREATING ALL THE WIDGETS 
    // THAT CORRESPONDS TO THE ELLIPTICAL ITEM YOU SEE IN THE SCENE
    else if(m_widgetState == ONLY_TF)

        //!pull out the layout that has been created when the
        //!widget instantiation state was = NONE

It has been quite a while that i am stuck with this issue and i am really looking forward to some hint.
