| 69 | * @See_also: #CtkTextBuffer, #CtkTextIter |
| 70 | * |
| 71 | * You may wish to begin by reading the |
| 72 | * [text widget conceptual overview][TextWidget] |
| 73 | * which gives an overview of all the objects and data |
| 74 | * types related to the text widget and how they work together. |

| 88 | * |
| 89 | * CtkTextView has a main css node with name textview and style class .view, |
| 90 | * and subnodes for each of the border windows, and the main text area, |
| 91 | * with names border and text, respectively. The border nodes each get |
| 92 | * one of the style classes .left, .right, .top or .bottom. |
| 93 | * |
| 94 | * A node representing the selection will appear below the text node. |
| 95 | * |
| 96 | * If a context menu is opened, the window node will appear as a subnode |
| 97 | * of the main node. |

| 101 | /* How scrolling, validation, exposes, etc. work. |
| 102 | * |
| 103 | * The expose_event handler has the invariant that the onscreen lines |
| 104 | * have been validated. |
| 105 | * |
| 106 | * There are two ways that onscreen lines can become invalid. The first |
| 107 | * is to change which lines are onscreen. This happens when the value |
| 108 | * of a scroll adjustment changes. So the code path begins in |
| 109 | * ctk_text_view_value_changed() and goes like this: |
| 110 | * - cdk_window_scroll() to reflect the new adjustment value |
| 111 | * - validate the lines that were moved onscreen |
| 112 | * - cdk_window_process_updates() to handle the exposes immediately |
| 113 | * |
| 114 | * The second way is that you get the “invalidated” signal from the layout, |
| 115 | * indicating that lines have become invalid. This code path begins in |
| 116 | * invalidated_handler() and goes like this: |
| 117 | * - install high-priority idle which does the rest of the steps |
| 118 | * - if a scroll is pending from scroll_to_mark(), do the scroll, |
| 119 | * jumping to the ctk_text_view_value_changed() code path |
| 120 | * - otherwise, validate the onscreen lines |
| 121 | * - DO NOT process updates |
| 122 | * |
| 123 | * In both cases, validating the onscreen lines can trigger a scroll |
| 124 | * due to maintaining the first_para on the top of the screen. |
| 125 | * If validation triggers a scroll, we jump to the top of the code path |
| 126 | * for value_changed, and bail out of the current code path. |
| 127 | * |
| 128 | * Also, in size_allocate, if we invalidate some lines from changing |
| 129 | * the layout width, we need to go ahead and run the high-priority idle, |
| 130 | * because CTK sends exposes right after doing the size allocates without |
| 131 | * returning to the main loop. This is also why the high-priority idle |
| 132 | * is at a higher priority than resizing. |
| 133 | * |
