A dropped press (a long touch, a canceled touch, a second finger) now
goes to the tool through Tool::drop_press, which takes Escape as during
a drag by default. The Pen, Smart Pen and Curvature tools override it
so the path being drawn goes on: they forget the press, and a Curvature
point the press dragged goes back where it was.
The release that follows runs only the tool's Cancel and Notify actions,
so a Selection marquee selects nothing and a Shift-drag Artboard marquee
toggles nothing. The engine puts back the persistent options the tool
had at the press (the Polygon tool's sides changed with the arrow keys),
and stores none of them.
A long touch, a canceled touch or a second finger drops the tool press in
progress. The tool used to get a plain mouse-up, which it cannot tell from a
release: the options the drag changed (the Polygon tool's sides set with the
arrow keys) were stored, and a shape tool pressed and held still opened its
size dialog.
Session::drop_tool_press undoes the press's interaction, sends the tool
Escape as during a drag, and then a release that returns it to rest without
storing the tool's options. What the tool asks of the UI along the way is
dropped.
While a polygon, star or rounded rectangle is dragged out, Up and Down
change its side count, point count or corner radius, and Ctrl/Cmd on a
star changes its inner-to-outer ratio. Escape canceled the drag but kept
those values, so the next drag and the tool's options started from a
shape that was never made.
- ShapeTool keeps those options as they were when the drag began and
Escape puts them back. A drag that is let go keeps the changed values.
An option set with tool.setOption during the drag stays.
- Session::tool_key saves the tool's options when a key cancels a
gesture, so the saved options and General > Corner Radius hold the
values Escape put back.
- docs/target-app-parity.md has one line for it.
Blob Brush Tool Options gain Angle (-180 to 180 degrees, 0 by default)
and Roundness (0 to 100 percent, 100 by default), with a preview of the
tip and three dabs; a drag in the preview square sets the Angle. The
elliptical tip keeps its angle on the page along a stroke, a 0 percent
tip is drawn 0.1 percent as wide as it is long, and Size set to
Pressure still varies its size. path.blob takes angle and roundness,
and both values are kept with the tool's options.
While a non-round tip drags, the Blob Brush shows the outline of the
area it covers with its length label, and an Alt drag that smooths
shows the Smooth tool's thin line.
With a path selected that the Smooth tool can change, Alt held at a
Paintbrush press now switches the drag to the Smooth tool: it smooths the
selected paths under the drag with the Smooth tool's radius and Smooth Tool
Options' Fidelity, and the cursor shows the Smooth tool before the press.
Alt pressed after a stroke begins still closes the path on release. With no
such path selected (nothing, only text or an image, or only a two-point
line), Alt at the press draws the closed stroke as before.
The Paintbrush no longer reads the Pencil's "Alt key toggles to Smooth Tool"
setting: its Alt close and Alt smoothing do not depend on it.
When Alt switches the Pencil (with Alt key toggles to Smooth Tool on)
or the Blob Brush to the Smooth tool, the drag sent the drawing tool's
own Fidelity (1.5 by default) to path.smoothRegion. The Smooth tool
sends its own Fidelity (2.5 by default, set in Smooth Tool Options).
Both tools now smooth with the Smooth tool's Fidelity. The engine gives
them the stored Smooth Fidelity when it makes the tool, and again when
Smooth Tool Options changes while one of them is active. Each tool's
own Fidelity still sets how its strokes are fitted.
