The line edit also supports pasting of unicode code in decimal or
hexadecimal format (i.e. 123 or 0x2713).
In addition, the character widget now grabs the keyboard
focus and will change the selected character based on
key stroke.
Previously, annotation size and position always used pixel units. This
did not work well when exporting layouts, resulting in tiny annotations
(it also caused issues when moving projects between hidpi/non hidpi
displays).
Instead, use millimeters for annotation size and position so that the
appearance is consistent across displays and works correctly in layout
exports.
Add lots of unit tests covering this.
Fixes#18373
populating batch processing dialog
This option adds news rows using the values from an expression
which returns an array. (As opposed to "Calculate by Expression",
which works only on existing rows).
The intended use case is to allow populating the batch dialog
using complex numeric series, e.g. those created by the "generate_series"
expression function.
For example, adding rows for a batch buffer using the expression
generate_series(100, 1000, 50)
(results in new rows with values 100, 150, 200, .... 1000)
This new option is available under the Autofill menu for a column. Selecting it allows users
to create a new QGIS expression to use to update the value inside that column. Existing
parameter values (including those from other columns) are available for use inside
the expression via @variables.
E.g. this allows setting output file names to complex expressions like
'/home/me/stuff/buffer_' || left(@input, 30) || '_' || @distance || '.shp'
to an explicit widget in the table
The double-click-header action is very hidden, and many users will
not stumble upon this. By moving it to an explicit "Autofill" widget at the
top of the table, we make this important action much more user
discoverable.
It also gives the possibility of other, parameter specific, autofill
actions (e.g. fill by expression, fill by file pattern)
- remove "Change" label and replace with larger dash preview icon.
The "change" text is unnecessary and adds to dialog clutter, better
to use the space for a wider preview icon (especially given that
the previous narrow icon never really showed enough of the pattern
to be useful!)
- don't offset the line in the preview if the symbol has an offset
set
- respond correctly to dash pattern, line width unit changes, cap
style changes
- show a nice big preview tooltip on hover
- Declare a minimum height to avoid narrow selection area
- Use application color palette instead of hardcoded values
- Decrease number of columns to better fit in the style dock
