QToolButton will not display its icon

[JimBrown]

Hello,

First, I want to thank the Qt Forum community for providing this great service. Many, many thanks.

My latest problem with a port from Qt 3 to Qt 4 is a QToolButton will not display its icon.
This was working code in Qt 3:

QToolButton*  myToolButton;
QWidget*      layoutWidget;
QHBoxLayout*  hboxLayout;
 
myToolButton = new QToolButton(layoutWidget);
myToolButton->setObjectName(QString::fromUtf8("myToolButton"));
myToolButton->setIcon(QIcon(QString::fromUtf8("images/icon_xpm")));
myToolButton->setCheckable(true);
 
hboxLayout->addWidget(myToolButton);
 
myToolButton->setToolTip("...");
myToolButton->setText(QString("..."));
 
editModeButtonGroup_->addButton(myToolButton, 0);

QToolButton*  myToolButton;
QWidget*      layoutWidget;
QHBoxLayout*  hboxLayout;

myToolButton = new QToolButton(layoutWidget);
myToolButton->setObjectName(QString::fromUtf8("myToolButton"));
myToolButton->setIcon(QIcon(QString::fromUtf8("images/icon_xpm")));
myToolButton->setCheckable(true);

hboxLayout->addWidget(myToolButton);

myToolButton->setToolTip("...");
myToolButton->setText(QString("..."));

editModeButtonGroup_->addButton(myToolButton, 0);

To copy to clipboard, switch view to plain text mode 

The dialog box displays and the buttons function, but they don't display their icon image. Any insight as to what's wrong?

Thanks again,
Jim Brown
