| 23 | * @Title: CtkLevelBar |
| 24 | * @Short_description: A bar that can used as a level indicator |
| 25 | * |
| 26 | * The #CtkLevelBar is a bar widget that can be used |
| 27 | * as a level indicator. Typical use cases are displaying the strength |
| 28 | * of a password, or showing the charge level of a battery. |
| 29 | * |
| 30 | * Use ctk_level_bar_set_value() to set the current value, and |
| 31 | * ctk_level_bar_add_offset_value() to set the value offsets at which |
| 32 | * the bar will be considered in a different state. CTK will add a few |
| 33 | * offsets by default on the level bar: #CTK_LEVEL_BAR_OFFSET_LOW, |
| 34 | * #CTK_LEVEL_BAR_OFFSET_HIGH and #CTK_LEVEL_BAR_OFFSET_FULL, with |
| 35 | * values 0.25, 0.75 and 1.0 respectively. |
| 36 | * |
| 37 | * Note that it is your responsibility to update preexisting offsets |
| 38 | * when changing the minimum or maximum value. CTK+ will simply clamp |
| 39 | * them to the new range. |
| 40 | * |
| 41 | * ## Adding a custom offset on the bar |
| 42 | * |
| 43 | * |[<!-- language="C" --> |
| 44 | * |
| 45 | * static CtkWidget * |
| 46 | * create_level_bar (void) |
| 47 | * { |
| 48 | * CtkWidget *widget; |
| 49 | * CtkLevelBar *bar; |
| 50 | * |
| 51 | * widget = ctk_level_bar_new (); |
| 52 | * bar = CTK_LEVEL_BAR (widget); |
| 53 | * |
| 54 | * // This changes the value of the default low offset |
| 55 | * |
| 56 | * ctk_level_bar_add_offset_value (bar, |
| 57 | * CTK_LEVEL_BAR_OFFSET_LOW, |
| 58 | * 0.10); |
| 59 | * |
| 60 | * // This adds a new offset to the bar; the application will |
| 61 | * // be able to change its color CSS like this: |
| 62 | * // |
| 63 | * // levelbar block.my-offset { |
| 64 | * // background-color: magenta; |
| 65 | * // border-style: solid; |
| 66 | * // border-color: black; |
| 67 | * // border-style: 1px; |
| 68 | * // } |
| 69 | * |
| 70 | * ctk_level_bar_add_offset_value (bar, "my-offset", 0.60); |
| 71 | * |
| 72 | * return widget; |
| 73 | * } |
| 74 | * ]| |
| 75 | * |
| 76 | * The default interval of values is between zero and one, but it’s possible to |
| 77 | * modify the interval using ctk_level_bar_set_min_value() and |
| 78 | * ctk_level_bar_set_max_value(). The value will be always drawn in proportion to |
| 79 | * the admissible interval, i.e. a value of 15 with a specified interval between |
| 80 | * 10 and 20 is equivalent to a value of 0.5 with an interval between 0 and 1. |
| 81 | * When #CTK_LEVEL_BAR_MODE_DISCRETE is used, the bar level is rendered |
| 82 | * as a finite number of separated blocks instead of a single one. The number |
| 83 | * of blocks that will be rendered is equal to the number of units specified by |
| 84 | * the admissible interval. |
| 85 | * |
| 86 | * For instance, to build a bar rendered with five blocks, it’s sufficient to |
| 87 | * set the minimum value to 0 and the maximum value to 5 after changing the indicator |
| 88 | * mode to discrete. |
| 89 | * |
| 90 | * CtkLevelBar was introduced in CTK+ 3.6. |
| 91 | * |
| 92 | * # CtkLevelBar as CtkBuildable |
| 93 | * |
| 94 | * The CtkLevelBar implementation of the CtkBuildable interface supports a |
| 95 | * custom <offsets> element, which can contain any number of <offset> elements, |
| 96 | * each of which must have name and value attributes. |
| 97 | * |
| 98 | * # CSS nodes |
| 99 | * |
| 100 | * |[<!-- language="plain" --> |
| 101 | * levelbar[.discrete] |
| 102 | * ╰── trough |
| 103 | * ├── block.filled.level-name |
| 104 | * ┊ |
| 105 | * ├── block.empty |
| 106 | * ┊ |
| 107 | * ]| |
| 108 | * |
| 109 | * CtkLevelBar has a main CSS node with name levelbar and one of the style |
| 110 | * classes .discrete or .continuous and a subnode with name trough. Below the |
| 111 | * trough node are a number of nodes with name block and style class .filled |
| 112 | * or .empty. In continuous mode, there is exactly one node of each, in discrete |
| 113 | * mode, the number of filled and unfilled nodes corresponds to blocks that are |
| 114 | * drawn. The block.filled nodes also get a style class .level-name corresponding |
| 115 | * to the level for the current value. |
| 116 | * |
| 117 | * In horizontal orientation, the nodes are always arranged from left to right, |
| 118 | * regardless of text direction. |
