[Qgis-developer] Re: Mac Snow Leopard - QGIS Symbology - Also windows symbology

[maaza mekuria]

Mars, I also have a problem that bears mentioning here (for QGIS 1.6 and 1.7 trunk). I have had QGIS crash when a layer's symbology had been defined using unique value of a field and that field is not there anymore. Anytime that layer is opened even if it was removed from the project first and added later, it crashes. It also crashes if the layer is renamed, or deleted outside QGIS (when QGIS is not running) and the project is opened not able access it. I think the layer definition and the symbology definition may be placed separately in the project file. (I am not sure exactly.)

I have also seen behaviors that are a bit unusual that some layers are listed first when the project opens up but are not really in the final visible Canvas layer list. I opened the project file and I see the XML data has them as layers but they are not part fo the visible layer. Is this a feature or a bug?

Maaza

Just out of curiosity, how is the QGIS Symbology Changing crashing issue coming along?
I just tested out Kyng's latest QGIS 1.7 r15814 for Snow Leopard (64bit Intel Qt 4.7 Cocoa)  [with all req. dep.]


and found the same hard crashing of QGIS when changing symbology of a feature.
I noticed there is an Active Ticket on this issue #3380



Any hope for QGIS users on Mac in the near future?
Thanks a lot!
Mars 

Just an Update. Will post to Ticket #3497 also for info.

So I decided to try building QGIS from trunk and give that a try.  Installed Qt 4.7.3 and all the other dependancies listed 

here on the QGIS Wiki: http://is.gd/AdHLiT

Ended up building the latest version of QGIS in trunk: 1.7.0 (1.7.0-Wroclaw (15870))

Build went fine.

No problems opening shapefiles, spatiallite, postgis, etc.


However, same issue when changing symbology of a layer.  QGIS hard crashes.

Sometimes it crashes on the first time setting symbology, sometimes on the 3rd or 4th time, but early enough.

This issue is actually a little depressing for me because I love using QGIS, but with out symbology I do find

it rather limiting.

cheers!

Mars
