This adds:
- API call to QgsMapCanvas to flash a set of features
- A right click menu option in the attribute table to flash
the clicked feature
- An option in the Search by Form dialog to flash matching
features
When triggered, the features flash allowing easy identification
without having to alter the current selection or map extent
Another bit to make core library independent from QgsProject::instance().
Until now labeling engine configuration was taken from project singleton.
Removed legacy methods from QgsPalLabeling - the class now does not have
any more member variables/methods, it is just a bunch of helper functions.
(PR #4384)
In a post-OTF-disabled world these are no longer required. The
map units are dictated by the map units for the destination
CRS.
It's dangerous to separate these two properties as setting
the incorrect map units for a given CRS will result in
incorrect scale calculations.
Because
- OTF reprojection is mature and stable
- Should be no cost when not required - transforms are shortcut
when not required
- Reduces code complexity
- Canvas OTF support was being incorrectly used as a flag for
whether measurements should be made in ellipsoidal mode. Instead
the project's ellipsoid setting should be checked for this.
- Should simplify behavior for new users
Qt5 allows runtime detection of touch devices. This commit reworks
the current touch map tool by pulling its behavior into the normal
pan tool when a touch device is detected.
It avoids the need for a seperate map tool for touch interaction,
and also avoids having this tool always appear on the Windows
builds (regardless of the presence of a touch device)
This change consolidates more unit handling and conversion into
QgsUnitTypes.
Additionally, UnknownUnit was renamed to UnknownDistanceUnit.
All methods which accepted QGis::UnitType parameters have been
updated to take QgsUnitTypes::DistanceUnit instead.
ALso remove the unit handling methods toLiteral, fromLiteral, tr,
fromTr, and fromUnitToUnitFactor from QGis. Their corresponding
counterparts in QgsUnitTypes should be used instead.
