Feature request #11632
Support for colour picker in colour dialog under OSX
|Pull Request or Patch supplied:||No||Resolution:||fixed/implemented|
|Easy fix?:||No||Copied to github as #:||19885|
Under macosx, the new colour picker does not show the "pippete" picker tab, as it is in the left part of this image
This is a very useful feature and it should be present!

It's due to a limitation with Qt under OSX - see the note under http://qt-project.org/doc/qt-4.8/qwidget.html#grabMouse
There's not much we can do until this is addressed by Qt. It may be possible to reimplement the feature using OSX specific apis, but that would require someone experienced in development under that platform to tackle this....

Thank you so much for your quick answer. So, in this case, why not give the users the option to choose the system colour picker for this single purpose (which, by the way, is excellent under macosx)? A simple button should be enought. This feature was in version 1.9 until 2.2 and it worked well. the pipette picker it's a time saver to build complex custom colour legends from digitised maps.

Hi Nyall. The option it's endeed there but it's not working for the pipette picker also. It is not well implemented. If we choose a new colour, the system picker appears. Then, if you choose the pipette, nothing happens. After, if we press "ok" into the colour picker, the magnifier from the colour pipette appears (after the closing of the colour picking palette) and it's impossible to choose any colour and its also difficult to make the magnifier go away. We have to press several times the mouse to make it go. Something is wrong in the code concerning the sequence of events for pipette colour picking while using the system option.

Thank you so much Nyall. I still have QGIS 1.8 installed and I'm still using it for this purpose (colour picking) because it was working nicely then. Until QGIS 2.4 all was fine too. Maybe someone can recover the specific code for pipette colour picking from one of these versions. Beyond this issue, the colour selecting features are working nicely, as expected.
