28 | 28 | \brief Defines a slice in pie series. |
|
29 | 29 | |
|
30 | 30 | This object defines the properties of a single slice in a QPieSeries. |
|
31 | 31 | |
|
32 | 32 | In addition to the obvious value and label properties the user can also control |
|
33 | 33 | the visual appearance of a slice. By modifying the visual appearance also means that |
|
34 | 34 | the user is overriding the default appearance set by the theme. |
|
35 | 35 | |
|
36 | 36 | Note that if the user has customized slices and theme is changed all customizations will be lost. |
|
37 | 37 | |
|
38 | 38 | To enable user interaction with the pie some basic signals are provided about clicking and hovering. |
