Add two realistic drawing styles for the terminal strip plan, besides
the existing schematic one:
- Realistic (push-in) and Realistic (screw): the strip seen from above,
at scale (real width of each terminal), like a cabinet mounting
drawing: end stops, group marker carrier with the strip name, one row
of wire entries per level, bridge channels with red bridges, marker
tags with the terminal number, type symbol (fuse, LED, diode,
sectional, ground...), green/yellow PE and terminal color.
The style is chosen for each plan in the "Add terminal strip plan"
dialog and saved with the item (attribute draw_style of
terminal_strip_item). Items saved before keep the schematic style.
Several plans of the same strip can use different styles.
The values used by the realistic styles are in the layout (scale in
px/mm, terminal length in mm, end stops, group marker) and can be set
in the layout editor, whose style combo box only changes the preview.
Separator plates: a new "Separator plate after" check box column in
the terminal strip editor, stored in the terminal element informations
(key terminal_separator). Drawn as a plate at scale in the realistic
styles and as a thick line in the schematic style.
New files: realisticterminalstripdrawer.{h,cpp} (realistic drawing) and
terminalstripdrawerhelpers.h (helpers shared with the schematic drawer).
The Selection properties "texts" tab painted the color value's own text in
that color, so the default black was unreadable on a dark palette. Show a
swatch in the cell instead and leave the text in the palette's color.
The terminal plan preview draws black ink with a white brush, like the
printed page it previews, on whatever background the view inherits from
the palette. Give the view a white background.
Initially it was planned to have separate text configuration for every
terminal level. It's not useful, use same properties for every level is
sufficient and visually more consistent.
By consequent every QVector related to these properties was replaced by
a single value.
The bounding rectangle used to define the position of the terminal text
can be edited. The y position and height can now be edited. The width is
not editable because is always the width of the rectangle of the of the
terminal.
