    Default QTreeWidgetItem - widget with layout collapsing

    Hello! I have troubles with creating userlist in my IM. Because I need to display some data in one Item. I decided to embed QFrame into widget, make layout and insert labels into that layout. Here is code of my function used to create item (pointer is returned, needed by userlist manager)

    Qt Code: 
    1. QTreeWidgetItem* QTlenRosterBox::addRosterItem(QString name,
    2.                                                QTlenPresence type,
    3.                                                QString desc,
    4.                                                QString jid,
    5. 					       QPixmap pxAvatar,
    7. {
    8.         QTreeWidgetItem*    item   = new QTreeWidgetItem(node);
    9.         QFrame*             frame = new QFrame(this);
    10.         QHBoxLayout*        hLayout = new QHBoxLayout(frame);
    11.         hLayout->setAlignment(Qt::AlignTop);
    12.         QVBoxLayout*        vLayout = new QVBoxLayout();
    13.         vLayout->setAlignment(Qt::AlignTop);
    14. 	QLabel*             statusIcon = new QLabel(frame);
    15.         statusIcon->setFixedSize(16,16);
    16.         switch (type)
    17.         {
    18.                 case Online:
    19.                         statusIcon->setPixmap(QPixmap(QString::fromUtf8(":/icons/icons/16x16/online.png")));
    20.                 break;
    21.                 case Chatty:
    22.                         statusIcon->setPixmap(QPixmap(QString::fromUtf8(":/icons/icons/16x16/chatty.png")));
    23.                 break;
    24.                 case Away:
    25.                         statusIcon->setPixmap(QPixmap(QString::fromUtf8(":/icons/icons/16x16/away.png")));
    26.                 break;
    27.                 case XA:
    28.                         statusIcon->setPixmap(QPixmap(QString::fromUtf8(":/icons/icons/16x16/xa.png")));
    29.                 break;
    30.                 case DND:
    31.                         statusIcon->setPixmap(QPixmap(QString::fromUtf8(":/icons/icons/16x16/dnd.png")));
    32.                 break;
    33.                 case Offline:
    34.                         statusIcon->setPixmap(QPixmap(QString::fromUtf8(":/icons/icons/16x16/offline.png")));
    35.                 break;
    36.         }
    37.  
    38.         hLayout->addWidget(statusIcon);
    39.         hLayout->addLayout(vLayout);
    40.         QLabel* nameLabel = new QLabel(name, frame);
    41.         QFont nameFont;
    42.         nameFont.setBold(true);
    43.         nameLabel->setFont(nameFont);
    44.         vLayout->addWidget(nameLabel);
    45. 	if (!desc.isEmpty() && settings->value("/roster/show_descriptions", false).toBool())
    46.         {
    47.             QLabel* descLabel = new QLabel(desc, frame);
    48.             QFont descFont;
    49.             descFont.setPointSize(7);
    50.             descFont.setItalic(true);
    51.             descLabel->setWordWrap(true);
    52.             descLabel->setFont(descFont);
    53.             vLayout->addWidget(descLabel);
    54. 	}
    55.         //prowizorka
    56. 	if(settings->value("/roster/show_avatars", false).toBool())
    57. 	{
    58. 	    QLabel* avatar = new QLabel();
    59. 	    if(pxAvatar.isNull())
    60. 		avatar->setPixmap(QPixmap(QString::fromUtf8(":/icons/icons/64x64/default_av.png")));
    61. 	    else
    62. 		avatar->setPixmap(pxAvatar);
    63. 	    avatar->setAlignment(Qt::AlignRight);
    64. 	    hLayout->addWidget(avatar);
    65. 	}
    66.         frame->setLayout(hLayout);
    67.         setItemWidget(item, 0, frame);
    68. 	return item;
    69. }
    To copy to clipboard, switch view to plain text mode 

    and here is roster with only one item visible and with two visible; height is calculated properly, but layout is collapsed.

    how to fix that in best way?
    thanks in advance.
