3.3.9 FileIconBox

  Open Motif 2.3 and later provide some "Contributed Widgets" such as XmIconButton and XmIconBox classes, which seem to be slightly similar to XmPushButton extension with a pixmap and XmButtonBox respectively. The XmIconButton can be used to show an icon (pixmap) and a label string simultaneously in a button.
On OZ++, to create an instance of IconButton, you have to specify XmNlalbelString and XmNpixmap resources as shown below:

IconButton* createIconButton(View* parent, const char* label, Pixmap iconPixmap)
  CompoundString cs(label);
  Args ar;
  ar.set(XmNlabelString, cs);
  ar.set(XmNiconPlacement, XmIconTop);
  ar.set(XmNpixmap, IconPixmap);
  return new IconButton(parent, label, ar);

The following ScrolledFileIconBox program is an example to display folders and files with pixmaps in FileIconBox (Motif++ 1.0.5) in ScrolledWindow.
