<DIV><FONT size=2 face=Arial>Hi,</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>i have build my own plugin for drawing
each kind of</FONT></DIV>
<DIV><FONT size=2 face=Arial>polygone over the map, unfortunately, it is not
opensource.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>but see the osmannotate plugin, this it a good
starting point.</FONT></DIV>
<DIV><FONT size=2 face=Arial>The plugin handles how to draw a polygone over
the map,</FONT></DIV>
<DIV><FONT size=2 face=Arial>check eventFilter:(...) methode and
m_drawingPolygone member .</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>for storing the polygone permanently (and
moving,modifying,...) i also suggest to create your own layer,</FONT></DIV>
<DIV><FONT size=2 face=Arial>it is not hard to do,</FONT></DIV>

class=gmail_quote>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>
