statusBar()->showMessage - causing jitter on status bar icons

[mattigot]

on my status bar i have a few buttons, i added them like this:

QPushButton* pb = new QPushButton(statusBar());
 
  QPixmap pixmap(icon);//the file name of the icon
  QIcon ButtonIcon(pixmap);
  pb->setIcon(ButtonIcon);
  QSize s(16,16);
  pb->setIconSize(s);
  QString tip(btnName);
  pb->setToolTip(tip);
  connect(pb, SIGNAL(clicked()), this, SLOT(statusBtnClicked()));

QPushButton* pb = new QPushButton(statusBar());

  QPixmap pixmap(icon);//the file name of the icon
  QIcon ButtonIcon(pixmap);
  pb->setIcon(ButtonIcon);
  QSize s(16,16);
  pb->setIconSize(s);
  QString tip(btnName);
  pb->setToolTip(tip);
  connect(pb, SIGNAL(clicked()), this, SLOT(statusBtnClicked()));

To copy to clipboard, switch view to plain text mode 

and later on i have an event onMouseMove, which basicly shows the mouse location on the status bar:

statusBar()->showMessage(moustlocationStr);
the buttons are displayed on the right side and the msg is on the left (by default) for some reason when i move the mouse and the msg of the mouse position changes, the left most icon jitters (moves a little bit to the side and quickly moves back to its place.)

i have no idea why.

any help?

Thank you.
