Fix #7549 (selection color is now stored in QgsRendererContext)

History

#1 Updated by Regis Haubourg about 11 years ago

confirmed,
maybe it is related to blending modes side effects?

Sounds like a QgsColorButton issue. Can't reproduce it here, but I copied over my previous pre-2.0 app settings (on Mac).

Is the Project Option's selection color button black? (That's the default color for the button, if one is not set.)

There is no indication in main Options that the current project overrides the app's selection color. Likewise, there seems to be no way to 'undo' a set project selection color, i.e. revert to app's.

#3 Updated by Larry Shaffer about 11 years ago

Ok, after temporarily removing my app prefs file, I could repeat the issue. It occurs because the undefined project's selection color is defaulting to black (even though it doesn't show that in the color button, which defaults to copying the app's, if it is not set).

To fix, open Project Options and click save. So, have to find why that is defaulting to black for the project.

Could be related to "this recent commit to master":commit:7cc3031f8884d768fe8405b7249cdc18e3c2571b"

Maybe Martin can shed light on the issue. Seems like maybe the new static QColor mSelectionColor of QgsSymbolV2RenderContext [0] isn't being updated or maybe it is being overridden later by a new context that doesn't read the settings(?).

Yes I may have broken something (though it seemed to work for me): I will have a look at that. The way how the selection is being handled (static variable) is rubbish anyway.
