| 2 | * jQuery add-on used to support context menus. |
| 3 | * Here's a list of supported options. |
| 4 | * |
| 5 | * - trigger string The command that should trigger the popup menu. Accepts the |
| 6 | * following values: click|doubleclick|rightclick|hover. |
| 7 | * Click will be used by default. |
| 8 | * - placement string Where the popup should be displayed in relation to the target. |
| 9 | * Accepts the following values: auto|top|right|bottom|left. |
| 10 | * Auto will be used by default (at the mouse coordinates). |
| 11 | * - class string An optional class to use for individual styling. |
| 12 | * - buttons object[] A list of buttons to include within the popup menu. See the options |
| 13 | * of the buttons for further details. |
| 14 | * - onShow function An optional callback to invoke when the popup menu is displayed. |
| 15 | * - onHide function An optional callback to invoke when the popup menu is dismissed. |
| 16 | * - darkMode mixed Flag for dark mode layout, which accepts 3 possible values: |
| 17 | * true|false|null. Pass true to always force the dark mode, false to |
| 18 | * always use the light mode, null to auto-detect the proper mode |
| 19 | * according to the preferred theme of the browser. |
| 20 | * - clickable boolean Flag used to check whether the root element should prevent the |
| 21 | * browser selection by applying specific CSS rules. False by default. |
| 22 | * - lockScroll boolean Flag used to prevent the document scroll when the context menu |
| 23 | * pops up. True by default. |
| 24 | * - hideOnEsc boolean Choose whether the context menu should be closed when ESC key is |
| 25 | * pressed. Always true by default. |
| 26 | * - formatShortcut mixed An optional callback that can be used to format the shortcut symbols. |
| 27 | * |
| 28 | * Here's a list of options supported by the buttons. Any other property of the button will |
| 29 | * be accessible by the internal methods. |
| 30 | * |
| 31 | * - icon mixed Either a function, an image URL, an image instance or a font icon |
| 32 | * to display before the button text. In case of a function, it will be |
| 33 | * used as callback to define an image/icon at runtime. |
| 34 | * - text string The text to display for the popup menu button. |
| 35 | * - action function The callback to dispatch when the button gets clicked. |
| 36 | * - class string An optional class to use for individual styling. |
| 37 | * - disabled mixed Either a function or a boolean to check whether the button should |
| 38 | * be clicked or not. The button is never disabled by default. |
| 39 | * - visible mixed Either a function or a boolean to check whether the button should |
| 40 | * be displayed or not. The button is always visible by default. |
| 41 | * - separator boolean Flag used to check whether the popup should include a separator after the |
| 42 | * button. False by default. |
| 43 | * - shortcut mixed An array of commands to represent the shortcut that will trigger the action |
| 44 | * via keyboard. The array must contain one and only one character or symbol. |
| 45 | * The array may contain one ore more modifiers, which must be specified first. |
| 46 | * |
| 47 | * List of methods supported by the add-on. |
| 48 | * |
| 49 | * - show Manually displays the popup menu. |
| 50 | * - hide Manually disposes the popup menu. |
| 51 | * - destroy Destroys the popup attached to the element. |
| 52 | * - config Returns the configuration of the popup. |
| 53 | * - buttons Getter/setter of the popup buttons. |
| 54 | * |
| 55 | * It is possible to update each setting configuration by using the same |
| 56 | * name of the property and the related value to set. Leave the set argument |
| 57 | * empty to simply access the current property value. In example: |
| 58 | * |
| 59 | * jQuery(target).vikContextMenu( 'trigger', 'click'); |
| 60 | * jQuery(target).vikContextMenu('placement', 'auto'); |
