| 40 | * @Title: Bindings |
| 41 | * @Short_description: Key bindings for individual widgets |
| 42 | * @See_also: Keyboard Accelerators, Mnemonics, #CtkCssProvider |
| 43 | * |
| 44 | * #CtkBindingSet provides a mechanism for configuring CTK+ key bindings |
| 45 | * through CSS files. This eases key binding adjustments for application |
| 46 | * developers as well as users and provides CTK+ users or administrators |
| 47 | * with high key binding configurability which requires no application |
| 48 | * or toolkit side changes. |
| 49 | * |
| 50 | * In order for bindings to work in a custom widget implementation, the |
| 51 | * widget’s #CtkWidget:can-focus and #CtkWidget:has-focus properties |
| 52 | * must both be true. For example, by calling ctk_widget_set_can_focus() |
| 53 | * in the widget’s initialisation function; and by calling |
| 54 | * ctk_widget_grab_focus() when the widget is clicked. |
| 55 | * |
| 56 | * # Installing a key binding |
| 57 | * |
| 58 | * A CSS file binding consists of a “binding-set” definition and a match |
| 59 | * statement to apply the binding set to specific widget types. Details |
| 60 | * on the matching mechanism are described under |
| 61 | * [Selectors][ctkcssprovider-selectors] |
| 62 | * in the #CtkCssProvider documentation. Inside the binding set |
| 63 | * definition, key combinations are bound to one or more specific |
| 64 | * signal emissions on the target widget. Key combinations are strings |
| 65 | * consisting of an optional #CdkModifierType name and |
| 66 | * [key names][cdk3-Keyboard-Handling] |
| 67 | * such as those defined in `cdk/cdkkeysyms.h` |
| 68 | * or returned from cdk_keyval_name(), they have to be parsable by |
| 69 | * ctk_accelerator_parse(). Specifications of signal emissions consist |
| 70 | * of a string identifying the signal name, and a list of signal specific |
| 71 | * arguments in parenthesis. |
| 72 | * |
| 73 | * For example for binding Control and the left or right cursor keys |
| 74 | * of a #CtkEntry widget to the #CtkEntry::move-cursor signal (so |
| 75 | * movement occurs in 3-character steps), the following binding can be |
| 76 | * used: |
| 77 | * |
| 78 | * |[ <!-- language="CSS" --> |
| 79 | * @binding-set MoveCursor3 |
| 80 | * { |
| 81 | * bind "<Control>Right" { "move-cursor" (visual-positions, 3, 0) }; |
| 82 | * bind "<Control>Left" { "move-cursor" (visual-positions, -3, 0) }; |
| 83 | * } |
| 84 | * |
| 85 | * entry |
| 86 | * { |
| 87 | * -ctk-key-bindings: MoveCursor3; |
| 88 | * } |
| 89 | * ]| |
| 90 | * |
| 91 | * # Unbinding existing key bindings |
| 92 | * |
| 93 | * CTK+ already defines a number of useful bindings for the widgets |
| 94 | * it provides. Because custom bindings set up in CSS files take |
| 95 | * precedence over the default bindings shipped with CTK+, overriding |
| 96 | * existing bindings as demonstrated in |
| 97 | * [Installing a key binding][ctk-bindings-install] |
| 98 | * works as expected. The same mechanism can not be used to “unbind” |
| 99 | * existing bindings, however. |
| 100 | * |
| 101 | * |[ <!-- language="CSS" --> |
| 102 | * @binding-set MoveCursor3 |
| 103 | * { |
| 104 | * bind "<Control>Right" { }; |
| 105 | * bind "<Control>Left" { }; |
| 106 | * } |
| 107 | * |
| 108 | * entry |
| 109 | * { |
| 110 | * -ctk-key-bindings: MoveCursor3; |
| 111 | * } |
| 112 | * ]| |
| 113 | * |
| 114 | * The above example will not have the desired effect of causing |
| 115 | * “<Control>Right” and “<Control>Left” key presses to be ignored by CTK+. |
| 116 | * Instead, it just causes any existing bindings from the bindings set |
| 117 | * “MoveCursor3” to be deleted, so when “<Control>Right” or |
| 118 | * “<Control>Left” are pressed, no binding for these keys is found in |
| 119 | * binding set “MoveCursor3”. CTK+ will thus continue to search for |
| 120 | * matching key bindings, and will eventually lookup and find the default |
| 121 | * CTK+ bindings for entries which implement word movement. To keep CTK+ |
| 122 | * from activating its default bindings, the “unbind” keyword can be used |
| 123 | * like this: |
| 124 | * |
| 125 | * |[ <!-- language="CSS" --> |
| 126 | * @binding-set MoveCursor3 |
| 127 | * { |
| 128 | * unbind "<Control>Right"; |
| 129 | * unbind "<Control>Left"; |
| 130 | * } |
| 131 | * |
| 132 | * entry |
| 133 | * { |
| 134 | * -ctk-key-bindings: MoveCursor3; |
| 135 | * } |
| 136 | * ]| |
| 137 | * |
| 138 | * Now, CTK+ will find a match when looking up “<Control>Right” and |
| 139 | * “<Control>Left” key presses before it resorts to its default bindings, |
| 140 | * and the match instructs it to abort (“unbind”) the search, so the key |
| 141 | * presses are not consumed by this widget. As usual, further processing |
| 142 | * of the key presses, e.g. by an entry’s parent widget, is now possible. |
