[Marble-devel] Re: Problem with map creation

[Mülner, Helmut]

Hi Torsten,

the problem with creating the TileCreatorDialog in a non-gui thread  happens when I have selected the cun control with the Night Map, and the Night Map has to be created.

Best regards,
Helmut

Hi Helmut,

I just removed all my tile data in my home directory and the Marble
configuration files.
Then I started Marble from master and
selected map themes which create tiles on runtime (such as Satellite,
Temperature, Precipitation, etc.).
Now all of this worked fine (and without a warning on the command line).
Usually the only problem with running stuff in a non-guithread is with
QPixmaps since they use the non-thread-safe XServer - at least if
true pixmaps are used (in graphicssystem "native" - since Marble is currently
using graphicssystem "raster" by default, I switched to "native" but still no
problems ...  .)

The usage of pixmaps in a non-guithread is usually indicated by a warning on
the command line (which doesn't occur here). Also I checked the tile creator
for QPixmaps (but we are just using QImage in there which is threadsafe).

So what am I doing "wrong" ? :-) How can I reproduce your issue?

Best Regards,

Torsten
