Description

- When loading a shapefile, display a progress bar to inform the user about the number of features geometries loaded (total number of features of a shapefile should be available inside dbf header) before final map rendering finally occurs.

- when opening attributes data table, display a progress bar to inform the user about the number of data records read inside the dbf file, before table view is finally displayed.

Hello, bug triage...

when you load the attribute table of a layer with lots of features (more than 100000 features, I am not sure what is the limit), there is a window indicating the number of features that have been loaded.

For layer rendering, I think this is impossible to have feature count because you can have a layer with lots of features which just loads in milliseconds because the features are not in the canvas extent (I can have a 1 million points layer loading instantly using this trick). For attribute table it is much more simple: you have to load everything. Furthermore, I can't see how to make a progressive feature count when you have multiple layers. Or perhaps would you like to have a global progressive feature count dialog box when rendering exceeds n seconds ?

I also think this is complex when using parallel rendering !

In the attribute table there is a progress bar and there are better ways (see #14994).
For rendering this doesn't make sense (see comment above by Médéric Ribreux).
