I forgot about that... so far there is grass + gdal providers which
implement populateHistogram(), we could add a hasCachedHistogram() to
the api, default returns false.
This way, it would always render the cached histogram if it exists,
but ask to compute if not.

A raster provider is not said it is a GDAL provider, so such
functionalitites must not be fitted to GDAL only...

You are right, that is the best approach. However, it might be best
to auto-load when the user actually switches to the tab.
A pain gdal does not have an API to query if the histogram is already
computed - this would require adding PAM-aware code to the gdal
provider.

Etienne, I don't think it's a good design to introduce such rules inside
the code (switching ti the first tab in case the remembered tab is the
histogram's).
Having the user to explicitely force the reload of the histogram is what I
would expect to find inside the tab... Maybe with the option, thro
Generally it is good practice that the UI remembers where the user left it
last time. In this case this has a bad user experience because of the slow
loading. My suggestion would be to just add a "Load histogram" button in
the histogram tab that loads the histogram rather then when the tab is
swi
I agree that this should not happen, should the default be always open
the first tab, or only when the histogram tab was previously selected?
Unfortunately there is no function in the provider API to know if
there is a cached histogram, so it would be better to never allow the
properties window to
A complex object to say something simple :(
When a user opens a layer settings window and hits a tab, the same tab
index is kept when opening another layer settings, or in a new qgis
sessions.
I had a small raster layer, and I opened the histogram tab.
The today I've opened a big raster layer, and
