/* This component represents a single "tile" in the launcher and the surrounding
25
The tile is square in size, with a side determined by the 'tileSize' property,
27
It is composed by a colored background layer, an icon (with 'icon' as source),
28
and a layer on top that provides a "shine" effect.
29
The main color of the background layer may be calculated based on the icon color
30
or may be fixed (depending on the 'backgroundFromIcon' property).
32
There's also an additional layer which contains only the outline of the tile
33
that is only appearing during the launching animation (when the 'launching' property is
34
true). During this animation the background fades out and the outline fades in,
35
giving a "pulsing" appearance to the tile.
37
Around the tile we may have on the left a number of "pips" between zero and three.
38
Pips are small icons used to indicate how many windows we have open for the current tile
39
(based on the 'windowCount' property).
40
The rule is: if there's only one window, we just display an arrow. If there are
41
two we display 2 pips, if there are 3 or more display 3 pips.
43
On the right of the tile there's an arrow that appears if the tile is currently 'active'.
45
Additionally, when the tile is marked as 'urgent' it will start an animation where the
46
rotation is changed so that it appears to be "shaking".
3
/* Item displaying an application.
6
- a generic bordered background image
7
- an icon representing the application
8
- a text describing the application
10
When an application is launched, the border changes appearance.
11
It supports mouse hover by changing the appearance of the background image.
13
The 'icon' property holds the source of the image to load as an icon.
14
The 'label' property holds the text to display.
15
The 'running' property is a boolean indicating whether or not the
16
application is launched.
18
The 'clicked' signal is emitted upon clicking on the item.
