Decorations buttons already use widget.Clickable and draw press ink, but they don't draw a hover/focus background. This makes custom window decorations appear unresponsive when the pointer is over minimize, maximize, or close buttons.
Register each button's system action over its clickable area and draw the same hovered background used by other material buttons. This also lets platforms query the button action from the material decorations hit area.

As suggested by ~egonelbre, Decorations should not be the source of truth
for the windows state, because external gestures may also change state.
This breaking change removes Decorations.Perform and exposes Maximized
as a bool which is the user's responsibility to set.

It's relatively common to create a widget and then add a background to
it. Using layout.Stack causes bunch of heap allocs, which we would like
to avoid whenever we can.
This adds layout.Background which is roughly the same as:
layout.Stack{Alignment: layout.C}.Layout(gtx,
layout.Expanded(background),
layout.Stacked(widget)
)

goarch: amd64

Similar to a previous change for Clickable and Bool this change separates
state changes from Decorations.Layout to Actions so that access may
happen before Layout.
Signed-off-by: Elias Naur <mail@eliasnaur.com>
Before this change, Clickable state updates would happen in Layout.
However, that is too late in cases where clicks affects layout that
contiains the Clickable.
This change removes state changes from Layout and moves them to Clicks,
to allow users pre-layout access. Note that Layout itself processes
events, which means users can no longer access clicks after Layout.

Allowing clients to initiate resize gestures is a waste: macOS
doesn't support them, and the only reason we added them was to
implement client-side decorations for Wayland. Now all desktop
platforms implement resize gestures as needed, and we no longer
need the system.Action actions.

Style values are ephemeral, and pointer methods can't be called in
the same expression a style value is constructed. Matches other style
types.

The unit.Value is a struct and thus more inconvenient to use than its
underlying float32 type. In addition, most uses don't need a general
value, but rather a specific unit given by the context. This change
replaces unit.Value with two float32 units, Dp and Sp. It also changes
variables and parameters of unit.Value to a specific unit type matching
the context. That is, unit.Dp everywhere except for text sizes which are
in Sp.
Switching to typed float32s has multiple advantages
- They can be constants:
const touchSlop = unit.Dp(16)
- Casting untyped constants is no longer necessary:
insets := layout.UniformInset(16)
- Calculation with values is natural:
func (s ScrollbarStyle) Width() unit.Dp {
return s.Indicator.MinorWidth + s.Track.MinorPadding + s.Track.MinorPadding
}
The main API change is that calls to gtx.Px must be replaced with either
gtx.Dp or gtx.Sp depending on the unit.

Like the change to op.Offset before this, clip.RRect and UniformRRect
is usually used with integer coordinates. Change to integer coordinates
to eliminate many useless conversions to float32.

op.Offset is a convenience function most often used by layouts. Layouts
usually operate in integer coordinates, and the float32 version of op.Offset
needlessly force conversions from int to float32. This change makes op.Offset
take integer coordinates, to better match its intended use.

Move Decorations to the widget package and
rename material.Decorate to material.Decorations.
This makes decorations in line with how the
other widgets are used.

Fix actions not processed and move the Layout method from
Decorations to DecorationsStyle.
Also clarify the comment for the app.Window.Decorated option.
Signed-off-by: Pierre Curto <pierre.curto@gmail.com>
This patch implements a mechanism for customizing window
decorations.
If a window is configured with app.Decorated(true), then
the widget/material.Decorations are applied. On Wayland,
the option is automatically set when the server does not
provide window decorations.
Server side decorations are no longer requested.
The Decorated flag is set according to the
server's requests.
Wayland is now the default driver for UNIX platforms.
