1. add a first shape vector layer - it is displayed

2. add another one, more/less located within the same region - it's not displayed

Turning layers of/on doesn't help. Refreshing neither.

Does the second datasource load and display fine if you do it first?

Try clicking on the 'zoom to full extents' button.

Can you attach the two shape files?

#2 Updated by Redmine Admin over 17 years ago

Partly my bad. The reason of the mess is that the two shapefiles are in differnet projections.

But I didn't notice that at first QGIS didn't handle the situation:

1. add layer odra_glogow_brzeg.shp - it is rendered

2. add the rzeki_ds.shp, it is not - nothing changes on the display

3. so I zoom to rzeki_ds layer extent, as my first reaction, and the extend changes but I still don't see my second layer! I still see the odra_glogow_brzeg one, zoomed-out, instead!

4. only when I 'zoom to full', I can see them both, separated with a big distance

5. but again, if I zoom to each particular layer's full extent, I always get only the odra_glogow_brzeg layer displayed, in two diffrent zoom levels

This is a real bug. I'm attaching the shapefiles.

A related wish: IMO, if on-the-fly projection is disabled, QGIS should inform the user that the second layer he is trying to open is in a different projection and ask if he want's to enable the on-the-fly projection using one of the 2 projections (user chooses which one).
