| 33 | /*** Structure: how CtkFileSystemModel works |
| 34 | * |
| 35 | * This is a custom CtkTreeModel used to hold a collection of files for CtkFileChooser. There are two use cases: |
| 36 | * |
| 37 | * 1. The model populates itself from a folder, using the GIO file enumerator API. This happens if you use |
| 38 | * _ctk_file_system_model_new_for_directory(). This is the normal usage for showing the contents of a folder. |
| 39 | * |
| 40 | * 2. The caller populates the model by hand, with files not necessarily in the same folder. This happens |
| 41 | * if you use _ctk_file_system_model_new() and then _ctk_file_system_model_add_and_query_file(). This is |
| 42 | * the special kind of usage for “search” and “recent-files”, where the file chooser gives the model the |
| 43 | * files to be displayed. |
| 44 | * |
| 45 | * Internal data structure |
| 46 | * ----------------------- |
| 47 | * |
| 48 | * Each file is kept in a FileModelNode structure. Each FileModelNode holds a GFile* and other data. All the |
| 49 | * node structures have the same size, determined at runtime, depending on the number of columns that were passed |
| 50 | * to _ctk_file_system_model_new() or _ctk_file_system_model_new_for_directory() (that is, the size of a node is |
| 51 | * not sizeof (FileModelNode), but rather model->node_size). The last field in the FileModelNode structure, |
| 52 | * node->values[], is an array of GValue, used to hold the data for those columns. |
| 53 | * |
| 54 | * The model stores an array of FileModelNode structures in model->files. This is a GArray where each element is |
| 55 | * model->node_size bytes in size (the model computes that node size when initializing itself). There are |
| 56 | * convenience macros, get_node() and node_index(), to access that array based on an array index or a pointer to |
| 57 | * a node inside the array. |
| 58 | * |
| 59 | * The model accesses files through two of its fields: |
| 60 | * |
| 61 | * model->files - GArray of FileModelNode structures. |
| 62 | * |
| 63 | * model->file_lookup - hash table that maps a GFile* to an index inside the model->files array. |
| 64 | * |
| 65 | * The model->file_lookup hash table is populated lazily. It is both accessed and populated with the |
| 66 | * node_get_for_file() function. The invariant is that the files in model->files[n] for n < g_hash_table_size |
| 67 | * (model->file_lookup) are already added to the hash table. The hash table will get cleared when we re-sort the |
| 68 | * files, as the array will be in a different order and the indexes need to be rebuilt. |
| 69 | * |
| 70 | * Each FileModelNode has a node->visible field, which indicates whether the node is visible in the CtkTreeView. |
| 71 | * A node may be invisible if, for example, it corresponds to a hidden file and the file chooser is not showing |
| 72 | * hidden files. Also, a file filter may be explicitly set onto the model, for example, to only show files that |
| 73 | * match “*.jpg”. In this case, node->filtered_out says whether the node failed the filter. The ultimate |
| 74 | * decision on whether a node is visible or not in the treeview is distilled into the node->visible field. |
| 75 | * The reason for having a separate node->filtered_out field is so that the file chooser can query whether |
| 76 | * a (filtered-out) folder should be made sensitive in the GUI. |
| 77 | * |
| 78 | * Visible rows vs. possibly-invisible nodes |
| 79 | * ----------------------------------------- |
| 80 | * |
| 81 | * Since not all nodes in the model->files array may be visible, we need a way to map visible row indexes from |
| 82 | * the treeview to array indexes in our array of files. And thus we introduce a bit of terminology: |
| 83 | * |
| 84 | * index - An index in the model->files array. All variables/fields that represent indexes are either called |
| 85 | * “index” or “i_*”, or simply “i” for things like loop counters. |
| 86 | * |
| 87 | * row - An index in the CtkTreeView, i.e. the index of a row within the outward-facing API of the |
| 88 | * CtkFileSystemModel. However, note that our rows are 1-based, not 0-based, for the reason explained in the |
| 89 | * following paragraph. Variables/fields that represent visible rows are called “row”, or “r_*”, or simply |
| 90 | * “r”. |
| 91 | * |
| 92 | * Each FileModelNode has a node->row field which is the number of visible rows in the treeview, *before and |
| 93 | * including* that node. This means that node->row is 1-based, instead of 0-based --- this makes some code |
| 94 | * simpler, believe it or not :) This also means that when the calling CtkTreeView gives us a CtkTreePath, we |
| 95 | * turn the 0-based treepath into a 1-based row for our purposes. If a node is not visible, it will have the |
| 96 | * same row number as its closest preceding visible node. |
| 97 | * |
| 98 | * We try to compute the node->row fields lazily. A node is said to be “valid” if its node->row is accurate. |
| 99 | * For this, the model keeps a model->n_nodes_valid field which is the count of valid nodes starting from the |
| 100 | * beginning of the model->files array. When a node changes its information, or when a node gets deleted, that |
| 101 | * node and the following ones get invalidated by simply setting model->n_nodes_valid to the array index of the |
| 102 | * node. If the model happens to need a node’s row number and that node is in the model->files array after |
| 103 | * model->n_nodes_valid, then the nodes get re-validated up to the sought node. See node_validate_rows() for |
| 104 | * this logic. |
| 105 | * |
| 106 | * You never access a node->row directly. Instead, call node_get_tree_row(). That function will validate the nodes |
| 107 | * up to the sought one if the node is not valid yet, and it will return a proper 0-based row. |
| 108 | * |
| 109 | * Sorting |
| 110 | * ------- |
| 111 | * |
| 112 | * The model implements the CtkTreeSortable interface. To avoid re-sorting |
| 113 | * every time a node gets added (which would lead to O(n^2) performance during |
| 114 | * the initial population of the model), the model can freeze itself (with |
| 115 | * freeze_updates()) during the intial population process. When the model is |
| 116 | * frozen, sorting will not happen. The model will sort itself when the freeze |
| 117 | * count goes back to zero, via corresponding calls to thaw_updates(). |
