With the introduction of 'activate' signal on [1], and the use of that
signal in Sugar Home, we introduced a bug, now, pressing the secondary button
starts the activity instead of open the palette.
This patch solves the issue checking the putton pressed before send the signal.
[1] a19cf9ed27
Commit a19cf9e changed the logic for handling CanvasIcon clicks. Therefore,
the visual state indicators must be updated to fit the new logic.
Test Case: Hold the mouse down on a home view icon. Move the mouse
in and out of the icon. See that the states correspond with what
happens if you release the mouse.
The mouse detector have a variable to store the id for the timeout.
The stop() method check if the id is null but do not set the id to null
after remove the GObject timeout, then try to remove the timeout multiple times.
The efect can be seen if a user move the mouse slowly over the icons
in the Sugar home, in shell.log we see many lines like:
sugar3/graphics/palettewindow.py:443: Warning: Source ID 2464 was not found
when attempting to remove it
The industry convention for mouse driven menu options is for them
to be activated when two conditions are met:
* a button down event occurs with the pointer inside the option, and;
* a button up event occurs with the pointer inside the option.
This issue was already solved on the PaletteMenuItem,
but the EventIcon have the same problem. This change add a 'activate' event,
that control that the two conditions are meet.
The code in Sugar need use this event instead of button-release-event.
When we use set_icon_widget(), GtkToolButton set a private property
contents_invalid = TRUE [1], and gtk_tool_button_construct_content [2]
is called. Then if the label widget not exist, a GtkLabel is added.
This is a problem for us, by example in the Clipboard buttons in the frame.
By adding a empty Gtk.Box instead of a label, we avoid the label creation.
But as this is a internal implementation of Gtk, can change in the future,
in fact the issue is not visible with Gtk < 3.16
This patch is based in a pr sent by Sam Parkinson
[1] https://github.com/GNOME/gtk/blob/master/gtk/gtktoolbutton.c#L1415
[2] https://github.com/GNOME/gtk/blob/master/gtk/gtktoolbutton.c#L357
The palette using a Gtk.Menu, had a separator displayed using a custom widget,
but that was not well displayed (the line didn't had the palette width
due to margin on the palette) and was broken on Gtk >= 3.16
Instead of use that widget to draw the separator line between at the bottom
of _HeaderItem, as we do with the toolbar buttons when the palette is displayed.
There are two different palette widgets in Sugar.
_PaletteMenuWidget is a Gtk.Menu and _PaletteWindowWidget is a Gtk.Window.
Only the palettes where the widget is a Gtk.Window can do present()
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.
[1] https://developer.gnome.org/gtk3/stable/GtkCellRenderer.html
Detecting if the treeview is scrolling we can improve the performance of
the CellRendererIcon by avoiding unneeded calculations.
The example scrollingdetector.py shows how this can be used. The
changes are backward compatible.

Use a more efficient method to check if the pointer is inside the cell,
because we have the cell_area in the do_render method.

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.

Push the palette widget opening process to the latest

takes of the place of the real palette.

When calculated the palette height based in the size of children,
forgoten add the border size. That moved the palette in the device icons
4 pixels to the bottom, then the gap was miscalcuated and the border
button border was not draw.

In Gtk 3.10, Gtk.Window is drawing a gray border around the palette.
This patch draw a black rectangle defore we draw Gtk.render_frame_gap
to draw the border but with a gap to connect to the attached widget.

Fix changes to label_alignment that does not honor
original vertical padding settings.

On Gtk 3.10, Gtk.Menu at the bottom of the screen are resized
to avoid fall out of the screen, then report a wrong height.
We need calculate the size of the children and move the Menu up.
This problem is visible on the Clipboard icon palettes,
and in journal objects palettes at the bottom of the screen.
This patch also rename a variable 'rect' to 'req', because is
a Requisition (width, height) and not a Rectangle (x, y, width, height).
Finally, to avoid a error with the secondary text on the palette,
when copy text from the terminal, reove the '¬r' character.

Since CellRendererInvoker can set the path at None if a mouse event
is out of the area of the renderer, can break the use of touch,
if happen after the mouse movement. This patch set the path,
in the point_in_cell_renderer test, for the positive case,
solving the issue.

pixel_size should be always used now.
Change SMALL_ICON_SIZE to cover the other sizes at settings.ini.
Adds a transformation to keep backwards compatibility for some
time. This will be removed in the future.
This issue was reported many times, when new users see a tooltip
try to click, and are confused when there are no action.
