This new invoker is able to handle all the palettes on a treeview,
removing the need of one invoker per cell renderer (CellRendererInvoker).
This simplifies the code and makes it more efficient.
Also removes the logic from the CellRendererIcon, which
should only care about drawing itself. [1]
Is important to note than in Gtk3 a CellRenderer is not a GtkWidget
then can't know when the mouse is over it or have the usual events
used by other invokers, making the implementation CellRendererInvoker
very complicate.
This commit also removes the invoker of CellRendererIcon.
The ScrollingDetector logic is simplified too,
because now there are only one invoker instead of one by renderer
and the example code updated.

PaletteWindow is the parent class of two different subclases,
Palette and _ToolBarPalette. Palette uses state changes intensively
in order to display secondary content, but _ToolBarPalette does not.
Because of this, Palette overwrites PaletteWindow's popup and popdown
methods adding one extra param called "state". This param is not required
either in PaletteWindow and specially not in _ToolBarPalette.
Therefore, any piece of code inside PaletteWindow which is meant for
Palette subclassing, should be moved out of PaletteWindow and placed
in the Palette class, where it corresponds.
This patch fixes the cases where _ToolBarPalette breaks because of this
mismatch.

There are cases where there is no user interaction but we do
receive a clicked signal: in the clipboard we do have
GtkRadioToolButton which are derived from the GtkToggleToolButton [1].
The 'clicked' signal is emitted when the 'active' property
changes [2]. We use the 'active' property to indicate the
current active clipping. In the Invoker we do check now
if the event originated a user interaction or if it was
generated due to a for example a property change.

This adds a property that indicates that a Palette should
behave in a locking manner. The behaviour is the same
as with the secondary Toolbars: when you hover over the invoking
widget the Palette will popdown and react to mouse movements,
leaving the invoker area or the Palette itself will popdown
the Palette again. When you click the invoking widget
the Palette will be locked. You have to unlock it again
to pop it down.
This patch makes the DescriptionButton and the Colorbutton
work.
If the DescriptionButton or the Colorbutton are placed in
the primary toolbar they will share the locked state with
the secondary toolbars. Only one can be locked at a time.
When a secondary toolbar is unlocked we do force that the
open Palettes are closed. Having a locking Palette in
a subtoolbar will also work (Activity Toolbar case or
ColorButton case in a few examples). There is no state
sharing implemented here at the moment, but so far we
do only have cases with one lockable Palette in a
subtoolbar.
This will also fix the case where we want to use the
OSK to edit the description of the activity SL #3887.

A new API is provided: PaletteMenuBox is a container to be used in
Palette.set_content(). This is to hide the implementation details and
set the corresponding paddings and sizes.
Usage:
box = PaletteMenuBox()
palette.set_content(box)
Then we can append items to it, like:
item = PaletteMenuItem(text_label, icon, xo_color=xo_color)
box.append_child(item)
separator = PaletteMenuItemSeparator()
box.append_child(item)
We can also append any widget, and the box will handle the paddings:
box.append_child(widget)
style.DEFAULT_PADDING for horizontal and vertical padding is the
default. But can be overriden:
box.append_child(widget, horizontal_padding=0, vertical_padding=0)
Details:
- move palettemenuitem.py to palettemenu.py
- Width of palette: make it a minimun size of 3 Sugar grid cells.
- Padding of content, secondary box: we need top and bottom padding,
which can be set when packing the items container inside the
secondary box.
- Padding of menu items: needs to be just for left and right, so move
the padding to a new horizontal box.
- Padding of separators: unlike GtkSeparatorMenuItem, GtkSeparator
doesn't support padding. But we can wrap it in a GtkEventBox and
force the height of the widget there.

This one is tricky because where the CellRendererInvoker is
used (Home View activity list and Journal list view) we do
use Palettes based on a GtkMenu. In the Journal list view
this Palette has submenus so it can not be easily replaced
with our custom Palette. That is why I am trying to make this
case work with a GtkMenu.
When the Palette does pop up it grabs the focus. This means that
the invoker does not see a TOUCH_END event. Same is the longpress
controller that is why we have to reset the controller when
the long-press is detected, otherwise it is not usable a second
time.
The default behavior of a GtkMenu is that it does pop down
on a long press/release event. So when doing a long press
on the icon the Palette was popping down directly. We can
stop this by listening on the button-release event in the
Menu and return True when the event happens in the invoker
coordinates.
Finally there are several issues with motion events: in the
invoker we listen to motion events on the treeview in order to
be able to popup/popdown the Palette on hovering over the
icon. This event is triggered as well when the icon is
tapped. We do check the origin of the event and do not trigger
the enter/leave when originated from a touchscreen. We do setup
the path for the CellRenderer however.
The second case where the motion events are triggered is
when you tap somewhere in the Palette when it is up. For
example you want to get to one of the submenues. Since the
Palette tracks motion events to work for the hover case [2]
we do get a leave event when the Palette is tapped and the
Palette does pop down. Same here, we check if the event
originated from a touchscreen and do discard it in that
case.

The WidgetInvoker will decide if a long press has been made
or not. We watch out for TOUCH_END events and when a long-press
event has been seen before we stop further propagation of the
event, hence there won't be any button-release or clicked
events available to the user of the widget.
There are several widgets using the WidgetInvoker, and those
handle differently touch events. The GtkButton does have a widget
implementation to handle touch events, it does stop further
propagation and emits the pressed/released signal for further
consumption [1]. We will not get a button-press/button-release
event for a touch event in this case.
The default behaviour for widgets e.g. a TreeView is to transform
the touch events into pointer events [2], for those widgets we do get
a button-press/button-release event for a touch events.

We are adding the x value twice (from the allocation and from the origin)
in get_rect of the WidgetInvoker which we derive from in the FrameInvoker.
In the toolkit-gtk2 code [1] we did add the allocation.x value when
the widget does not provide its own gtk.gdk.Window (gtk.NO_WINDOW) [2]. This
is the same check we do above if the widget has a window and we set x and y
to 0 there which sounds sane enough to me.

First we needed to port the Palette code to use a minimum size. The default size
is two times the GRID_CELL_SIZE. Since the request-phase of the traditional GTK+

to compensate for that. Furthermore we need to pass the invoker from the
PaletteWindow to the _PaletteWindowWidget for the gap calculation code for
drawing the border around the Palette.
We do the drawing of the border for the toolbutton in the base class, moved
this from the ToolbarButton and made sure we are drawing in the right order.
In the ToolButton we draw as well a black background for the ToolButton when
the Palette is up. While the mouse is over the button we can do that in the
theme, but not when the mouse moves over the Palette.

Moving from GTK2 to GTK3 has presented various challenges regarding
palettes.
In GTK2, we were able to access some internal API of the GtkMenu class
and use it to embed a GtkMenu in a regular window. As of GTK3, that API
has become private and we can no longer access it.
We still want to use GtkMenu for the advanced functionality it provides
(multiple-level menus, keyboard navigation, etc), but we are now limited
to popping it up with its own (internal) window, rather than being able
to pack it into one of our own.
Our palettes can historically be used either as a menu, or as a general
area where widgets can be added, or both. The new restrictions upon
GtkMenu force some changes here, but we work hard to stick to the old
API as far as possible.
A Palette instance now acts as a controller of either a "window widget"
(where any type of widget can be displayed as usual) or a "menu widget"
which just pops up a GtkMenu. A Palette defaults to the window mode, but
dynamically switches to menu mode if/when the user attempts to access
the menu element.
As a result of this, palettes can now pack either a user-defined collection
of widgets, or a menu, but types can no longer be mixed. This should
only affect a handful of palettes which will need to pick a single
approach and convert to it.
Some further challenges are presented by the fact that GtkMenu performs a
grab on the whole screen, meaning that all input events are delivered to
the GtkMenu widget. Through some careful event filtering and examination
of the mouse cursor position we are still able to determine when the mouse
has entered or left the invoker or menu areas.
This work is authored by Benjamin Berg, Marco Pesenti Gritti, Simon
Schampijer and Daniel Drake.
CanvasIcon and CanvasInvoker were removed in a previous GTK3-porting commit
as they were based on hippocanvas.
However, this leaves the toolkit with some missing functionality:
there is no longer a trivial way to show an icon which can receive mouse
events and pop up a palette. Such functionality is used in various
places throughout the shell and activities.
Reimplement this functionality as EventIcon and CursorInvoker.
Instead of reimplementing much of the Icon class (like CanvasIcon did),
EventIcon opts for a more simplistic encapsulation of an Icon object.
This means trivial API changes for CanvasIcon users who must now
use the 'icon' property with the Icon API.
