Hi Kyle,<br>
<br>
an easy way (hack) would be to use the selection rubber band Marble uses<br>
when you hold Ctrl and do the interaction you describe. You can access<br>
that rectangle via the MarbleWidget::regionSelected(QList<double>)<br>
signal. The list contains the border points (west, north, east, south,<br>
in degree). To make it persistent, add your own layer as described in<br>
the tutorials and have it paint the rectangle. Alternatively, create a<br>
suitable .kml file with the rectangle, style it and add it to the map<br>
via MarbleWidget::model()->addGeoDataString() or addGeoDataFile().<br>
You can also add another event filter on the widget and handle the user<br>
actions similarly to how MarbleWidgetDefaultInputHandler implements the<br>
rubber band selection.<br>
<br>
Regards,<br>
Dennis<br>
