<DIV><FONT size=2 face=Arial>Hello marble dev team,</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>i am working on a GIS app using the famous
</FONT><FONT size=2 face=Arial>marblewidget.</FONT></DIV>
<DIV><FONT size=2 face=Arial>doing this i am now facing a memory leak
problem,</FONT></DIV>
<DIV><FONT size=2 face=Arial>i tried to fix but failed.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>find attached simple TestRender plugin code
(VisualStudio 2005 sln),</FONT></DIV>
<DIV><FONT size=2 face=Arial>this shows you the problem.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>this plugin creates a new marble layer, all this
layer is doing</FONT></DIV>
<DIV><FONT size=2 face=Arial>is to draw a polyline
(GeoDataLineString).</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>in TestRender::initialize() i create the layer and
start a timer.</FONT></DIV>
<DIV><FONT size=2 face=Arial>the timer signal timeout() calls the
TestRender::slotUpdateMap()</FONT></DIV>
<DIV><FONT size=2 face=Arial>every 500msec.</FONT></DIV>
<DIV><FONT size=2 face=Arial>within this slot a GeoDataLineString is
created end sent to the layer by</FONT></DIV>
<DIV><FONT size=2 face=Arial>emit signalUpdatePoly() .</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>so on the map you can see the polyline moving from
left to right</FONT></DIV>
<DIV><FONT size=2 face=Arial>and back.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>everything is ok, but use this plugin and watch
memory usage -</FONT></DIV>
<DIV><FONT size=2 face=Arial>it grows up every time the ployline is
updatet.</FONT> </DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>note: use latest unstable marblewidget/marble
version to get the plugin</FONT></DIV>
<DIV><FONT size=2 face=Arial>working.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>hope you are able to fix this memory
leak,</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>thanks for support,</FONT></DIV>
