1. never set both width and height, just set width.
2. don't use pixels to set the width use percentages
In your case you have 3 images so divide 100% in 3 which is about 33%, so give the images the size of 33% (or a little less if the cont... |

Based on what I know about default VirtualBox network settings, your host only connection that uses `192.168.10.10` is on the incorrect subnet and that adjustment is being done in the wrong area to get this thing working.

In your example, you're attempting to set up a host-only network in VirtualBox that consists of one guest machine only, and of course the host machine.
Keep in mind, however, that *Host-only networking* is designed so that it can accommodate multiple guest mach... |

] | This means that the classifier variable is declared as a superclass or superinterface of `AttributeSelectedClassifier`, and that you need to call a method which is not defined in the class or interface, but only on `AttributeSelectedClassifier`.
