This new class, QgsBlockingNetworkRequest, is designed for
performing SAFE blocking requests. It is thread safe and
has full support for QGIS proxy and authentication settings.
This class should be used whenever a blocking network
request is required. Unlike implementations
which rely on QApplication::processEvents() or creation of a
QEventLoop, this class is completely
thread safe and can be used on either the main thread or
background threads without issue.
Redirects are automatically handled by the class.
After completion of a request, the reply content should be
retrieved by calling getReplyContent().
This method returns a QgsNetworkReplyContent container,
which is safe and cheap to copy and pass
between threads without issue.
The guts of this class have been copied from QgsWfsRequest (which
has been using the same approach since 3.2)
Encapsulates a network reply within a container which
is inexpensive to copy and safe to pass around between threads.
The default Qt QNetworkReply class is a QObject, which prevents
it from being copied and passed between threads. This class
grabs all the useful information from a QNetworkReply,
allowing the reply's content to be stored indefinetly without
concern for the lifetime of the QNetworkReply object itself.
This feature allows other layout items (such as scalebars,
north arrows, inset maps, etc) to be marked as a blockers for
the map labels in a map item. This prevents any map labels from
being placed under those items - causing the labeling engine
to either try alternative placement for these labels (or
discarding them altogether)
This allows for more cartographically pleasing maps -- placing
labels under other items can make them hard to read, yet without
this new setting it's non-trivial to get QGIS to avoid placing
the labels in these obscured areas.
The blocking items are set through a map item's properties, under
the label settings panel. The setting is per-map item, so you can have
a scalebar block the labels for one map in your layout and not others
(if you so desire!)
