This allows registration of item creation actions which create
items with an existing item type, but custom creation functions.
E.g. allowing actions for creation of ellipse/triangles/etc
from a single layout item type.
In compositions, a flag must be explicitly set to indicate
whether the render occuring is for "previews" (i.e.
rendering in a graphics view) or outputs (i.e. rendering
to a image/pdf/other destination device)
This isn't nice api.
So we avoid this by checking the paint device type when
an item is being rendered.
type of item, just update the existing panel to show the new
item's properties
This means that flicking between selecting items of the same
type will not create a new properties widget, so scroll
bar positions, focused widgets, etc are all maintained.
Makes using layouts less annoying.
to use for their algorithm's parameters
Because some providers do not have support for all output types,
we need to give providers a way to restrict the default format
choices to those which are supported by the provider.
Initially only flag available is whether to sort drivers by
recommended order. The recommended order puts GPKG first and
SHP second, then leaves the rest alphabetical.
This fixes a few instances in the QGIS gui where these recommended formats
are not listed first.
* A new createopt textbox has been added to the parameters dialog for algorithms which exports to raster files.
* A new metaopt textbox has also been added to the Algorithm parameters dialog.
* Raster file format is detected from output filename extension.
* GdalUtils has been improved to correctly detect raster formats supported for creation.
* QFileDialog for output rasters now display only file filters for supported output raster file formats.
- Improve GRASS detection for all OS.
- Use GRASS --exec command.
- Unified GRASS batch job method for all OS (easier to maintain).
- Handle MS-Windows codepages (for data only, if you have a username with special characters, it will not work).
- Better support for filepath normalization.
- add -m option to r.out.gdal.
