docs » hs.webview.toolbar

Create and manipulate toolbars which can be attached to the Hammerspoon console or hs.webview objects.

Toolbars are attached to titled windows and provide buttons which can be used to perform various actions within the application. Hammerspoon can use this module to add toolbars to the console or hs.webview objects which have a title bar (see hs.webview.windowMasks and hs.webview:windowStyle). Toolbars are identified by a unique identifier which is used by OS X to identify information which can be auto saved in the application's user defaults to reflect changes the user has made to the toolbar button order or active button list (this requires setting hs.webview.toolbar:autosaves and hs.webview.toolbar:canCustomize both to true).

Multiple copies of the same toolbar can be made with the hs.webview.toolbar:copy method so that multiple webview windows use the same toolbar, for example. If the user customizes a copied toolbar, changes to the active buttons or their order will be reflected in all copies of the toolbar.

Example:

t = require("hs.webview.toolbar")
a = t.new("myConsole", {
        { id = "select1", selectable = true, image = hs.image.imageFromName("NSStatusAvailable") },
        { id = "NSToolbarSpaceItem" },
        { id = "select2", selectable = true, image = hs.image.imageFromName("NSStatusUnavailable") },
        { id = "notShown", default = false, image = hs.image.imageFromName("NSBonjour") },
        { id = "NSToolbarFlexibleSpaceItem" },
        { id = "navGroup", label = "Navigation", groupMembers = { "navLeft", "navRight" }},
        { id = "navLeft", image = hs.image.imageFromName("NSGoLeftTemplate"), allowedAlone = false },
        { id = "navRight", image = hs.image.imageFromName("NSGoRightTemplate"), allowedAlone = false },
        { id = "NSToolbarFlexibleSpaceItem" },
        { id = "cust", label = "customize", fn = function(t, w, i) t:customizePanel() end, image = hs.image.imageFromName("NSAdvanced") }
    }):canCustomize(true)
      :autosaves(true)
      :selectedItem("select2")
      :setCallback(function(...)
                        print("a", inspect(table.pack(...)))
                   end)

t.attachToolbar(a)

API Overview

API Documentation

Constants

itemPriorities
Signature hs.webview.toolbar.itemPriorities
Type Constant
Description

A table containing some pre-defined toolbar item priority values for use when determining item order in the toolbar.

Defined keys are:

  • standard - the default priority for an item which does not set or change its priority
  • low - a low priority value
  • high - a high priority value
  • user - the priority of an item which the user has added or moved with the customization panel
systemToolbarItems
Signature hs.webview.toolbar.systemToolbarItems
Type Constant
Description

An array containing string identifiers for supported system defined toolbar items.

Currently supported identifiers include:

  • NSToolbarSpaceItem - represents a space approximately the size of a toolbar item
  • NSToolbarFlexibleSpaceItem - represents a space that stretches to fill available space in the toolbar

Functions

attachToolbar
Signature hs.webview.toolbar.attachToolbar([obj1], [obj2]) -> obj1
Type Function
Description

Get or attach/detach a toolbar to the console or webview.

Parameters:

  • if no arguments are present, this function returns the current toolbarObject for the Hammerspoon console, or nil if one is not attached.
  • if one argument is provided and it is a toolbarObject or nil, this function will attach or detach a toolbarObject to/from the Hammerspoon console.
  • if one argument is provided and it is a webviewObject, this function will return the current toolbarObject for the webview, or nil if one is not attached.
  • if two arguments are provided and the first is a webviewObject and the second is a toolbarObject or nil, this function will attach or detach a toolbarObject to/from the webview.

Returns:

  • if the function is used to attach/detach a toolbar, then the first object provided will be returned ; if this function is used to get the current toolbar object for a webview or the console, then the toolbarObject or nil will be returned.

Notes:

  • This function is not expected to be used directly (though it can be) -- it is added to the hs.webview object metatable so that it may be invoked as hs.webview:attachedToolbar([toolbarObject | nil]) and to the hs.console module so that it may be invoked as hs.console.toolbar([toolbarObject | nil]).

  • If the toolbar is currently attached to another window when this function is called, it will be detached from the original window and attached to the new one specified by this function.

Constructors

new
Signature hs.webview.toolbar.new(toolbarName, [toolbarTable]) -> toolbarObject
Type Constructor
Description

Creates a new toolbar for a webview or the console.

Parameters:

  • toolbarName - a string specifying the name for this toolbar
  • toolbarTable - an optional table describing possible items for the toolbar

Returns:

  • a toolbarObject

Notes:

Methods

addItems
Signature hs.webview.toolbar:addItems(toolbarTable) -> toolbarObject
Type Method
Description

Add one or more toolbar items to the toolbar

Parameters:

  • toolbarTable - a table describing a single toolbar item, or an array of tables, each describing a separate toolbar item, to be added to the toolbar.

Returns:

  • the toolbarObject

Notes:

  • Each toolbar item is defined as a table of key-value pairs. The following list describes the valid keys used when describing a toolbar item for this method, the constructor hs.webview.toolbar.new, and the hs.webview.toolbar:modifyItem method. Note that the id field is required for all three uses.
    • id - A unique string identifier required for each toolbar item and group. This key cannot be changed after an item has been created.
    • allowedAlone - a boolean value, default true, specifying whether or not the toolbar item can be added to the toolbar, programmatically or through the customization panel, (true) or whether it can only be added as a member of a group (false).
    • default - a boolean value, default matching the value of allowedAlone for this item, indicating whether or not this toolbar item or group should be displayed in the toolbar by default, unless overridden by user customization or a saved configuration (when such options are enabled).
    • enable - a boolean value, default true, indicating whether or not the toolbar item is active (and can be clicked on) or inactive and greyed out. This field is ignored when applied to a toolbar group; apply it to the group members instead.
    • fn - a callback function, or false to remove, specific to the toolbar item. This property is ignored if assigned to the button group. This function will override the toolbar callback defined with hs.webview.toolbar:setCallback for this specific item. The function should expect three (four, if the item is a searchfield) arguments and return none. See hs.webview.toolbar:setCallback for information about the callback's arguments.
    • groupMembers - an array (table) of strings specifying the toolbar item ids that are members of this toolbar item group. If set to false, this field is removed and the item is reset back to being a regular toolbar item. Note that you cannot change a currently visible toolbar item to or from being a group; it must first be removed from active toolbar with hs.webview.toolbar:removeItem.
    • image - an hs.image object, or false to remove, specifying the image to use as the toolbar item's icon when icon's are displayed in the toolbar or customization panel. This key is ignored for a toolbar item group, but not for it's individual members.
    • label - a string label, or false to remove, for the toolbar item or group when text is displayed in the toolbar or in the customization panel. For a toolbar item, the default is the id string; for a group, the default is false. If a group has a label assigned to it, the group label will be displayed for the group of items it contains. If a group does not have a label, the individual items which make up the group will each display their individual labels.
    • priority - an integer value used to determine toolbar item order and which items are displayed or put into the overflow menu when the number of items in the toolbar exceed the width of the window in which the toolbar is attached. Some example values are provided in the hs.webview.toolbar.itemPriorities table. If a toolbar item is in a group, it's priority is ignored and the item group is ordered by the item group's priority.
    • searchfield - a boolean (default false) specifying whether or not this toolbar item is a search field. If true, the following additional keys are allowed:
      • searchHistory - an array (table) of strings, specifying previous searches to automatically include in the search field menu, if searchPredefinedMenuTitle is not false
      • searchHistoryAutosaveName - a string specifying the key name to save search history with in the application deafults (accessible through hs.settings). If this value is set, search history will be maintained through restarts of Hammerspoon.
      • searchHistoryLimit - the maximum number of items to store in the search field history.
      • searchPredefinedMenuTitle - a string or boolean specifying how a predefined list of search field "response" should be included in the search field menu. If this item is true, this list of items specified for searchPredefinedSearches will be displayed in a submenu with the title "Predefined Searches". If this item is a string, the list of items will be displayed in a submenu with the title specified by this string value. If this item is false, then the search field menu will only contain the items specified in searchPredefinedSearches and no search history will be included in the menu.
      • searchPredefinedSearches - an array (table) of strings specifying the items to be listed in the predefined search submenu. If set to false, any existing menu will be removed and the search field menu will be reset to the default.
      • searchReleaseFocusOnCallback - a boolean, default false, specifying whether or not focus leaves the search field text box when the callback is invoked. Setting this to true can be useful if you want subsequent keypresses to be caught by the webview after reacting to the value entered into the search field by the user.
      • searchText - a string specifying the text to display in the search field.
      • searchWidth - the width of the search field text entry box.
    • selectable - a boolean value, default false, indicating whether or not this toolbar item is selectable (i.e. highlights, like a selected tab) when clicked on. Only one selectable toolbar item can be highlighted at a time, and you can get or set/reset the selected item with hs.webview.toolbar:selectedItem.
    • tag - an integer value which can be used for own purposes; has no affect on the visual aspect of the item or its behavior.
    • tooltip - a string label, or false to remove, which is displayed as a tool tip when the user hovers the mouse over the button or button group. If a button is in a group, it's tooltip is ignored in favor of the group tooltip.
allowedItems
Signature hs.webview.toolbar:allowedItems() -> array
Type Method
Description

Returns an array of all toolbar item identifiers defined for this toolbar.

Parameters:

  • None

Returns:
autosaves
Signature hs.webview.toolbar:autosaves([bool]) -> toolbarObject | bool
Type Method
Description

Get or set whether or not the toolbar autosaves changes made to the toolbar.

Parameters:

  • an optional boolean value indicating whether or not changes made to the visible toolbar items or their order is automatically saved.

Returns:

  • if an argument is provided, returns the toolbar object; otherwise returns the current value

Notes:

  • If the toolbar is set to autosave, then a user-defaults entry is created in org.hammerspoon.Hammerspoon domain with the key "NSToolbar Configuration XXX" where XXX is the toolbar identifier specified when the toolbar was created.
  • The information saved for the toolbar consists of the following:
    • the default item identifiers that are displayed when the toolbar is first created or when the user drags the default set from the customization panel.
    • the current display mode (icon, text, both)
    • the current size mode (regular, small)
    • whether or not the toolbar is currently visible
    • the currently shown identifiers and their order
    • Note that the labels, icons, callback functions, etc. are not saved -- these are determined at toolbar creation time, by the hs.webview.toolbar:addItems, or by the hs.webview.toolbar:modifyItem method and can differ between invocations of toolbars with the same identifier and button identifiers.
