Detail

This widget underwent a signficant overhaul in gtk 2.4 and the recommended api changed substantially. The old interface is still supported but it is not recommended.

The following information applies to the new interface only.

A toolbar is created with a call to toolbarNew.

A toolbar can contain instances of a subclass of ToolItem. To add a ToolItem to the a toolbar, use toolbarInsert. To remove an item from the toolbar use containerRemove. To add a button to the toolbar, add an instance of ToolButton.

Toolbar items can be visually grouped by adding instances of SeparatorToolItem to the toolbar. If a SeparatorToolItem has the "expand" property set to True and the "draw" property set to False the effect is to force all following items to the end of the toolbar.

Creating a context menu for the toolbar can be done using onPopupContextMenu.

The following information applies to the old interface only.

Buttons, RadioButtons and ToggleButtons can be added by refering to stock images. Their size can be changed by calling toolbarSetIconSize. In contrast, normal widget cannot be added. Due to the bad interface of Toolbar mnemonics of RadioButtons and ToggleButtons are not honored.

All the append, insert and prepend functions use an internal function to do the actual work. In fact the interface is pretty skrewed up: To insert icons by using stock items is definitely the best practice as all other images cannot react to toolbarSetIconSize and other theming actions. On the other hand toolbarInsertStock always generates simple Buttons but is the only function that is able to insert Mnemonics on the label. Our solution is to use StockItems to specify all Images of the Buttons. If the user inserts RadioButtons or ToggleButtons, the stock image lookup is done manually. A mnemonic in the labels is sadly not honored this way.

toolbarNew :: IO Toolbar

Creates a new toolbar.

Methods

toolbarInsertNewButton :: ToolbarClass self => self -> Int -> String -> Maybe (String, String) -> IO Button

Insert a new Button into the Toolbar.

The new Button is created at position pos, counting from 0.

The icon and label for the button is referenced by stockId which must be a valid entry in the Toolbars Style or the default IconFactory.

If you whish to have Tooltips added to this button you can specify Just (tipText, tipPrivate) , otherwise specify Nothing.

The newly created Button is returned. Use this button to add an action function with "connectToClicked".

Warning: this function is deprecated and should not be used in newly-written code.

toolbarAppendNewButton :: ToolbarClass self => self -> String -> Maybe (String, String) -> IO Button

Append a new Button to the Toolbar.

See toolbarInsertNewButton for details.

Warning: this function is deprecated and should not be used in newly-written code.

toolbarPrependNewButton :: ToolbarClass self => self -> String -> Maybe (String, String) -> IO Button

Prepend a new Button to the Toolbar.

See toolbarInsertNewButton for details.

Warning: this function is deprecated and should not be used in newly-written code.

toolbarInsertNewToggleButton :: ToolbarClass self => self -> Int -> String -> Maybe (String, String) -> IO ToggleButton

Insert a new ToggleButton into the Toolbar.

See toolbarInsertNewButton for details.

Warning: this function is deprecated and should not be used in newly-written code.

toolbarAppendNewToggleButton :: ToolbarClass self => self -> String -> Maybe (String, String) -> IO ToggleButton

Append a new ToggleButton to the Toolbar.

See toolbarInsertNewButton for details.

Warning: this function is deprecated and should not be used in newly-written code.

toolbarPrependNewToggleButton :: ToolbarClass self => self -> String -> Maybe (String, String) -> IO ToggleButton

Prepend a new ToggleButton to the Toolbar.

See toolbarInsertNewButton for details.

Warning: this function is deprecated and should not be used in newly-written code.

toolbarInsertNewRadioButton :: (ToolbarClass self, RadioButtonClass rb) => self -> Int -> String -> Maybe (String, String) -> Maybe rb -> IO RadioButton

Insert a new RadioButton into the Toolbar.

See toolbarInsertNewButton for details.

Warning: this function is deprecated and should not be used in newly-written code.

The parent argument must be set to another RadioButton in the group. If Nothing is given, a new group is generated (which is the desired behavious for the first button of a group).

Warning: this function is deprecated and should not be used in newly-written code.

toolbarAppendNewRadioButton :: (ToolbarClass self, RadioButtonClass rb) => self -> String -> Maybe (String, String) -> Maybe rb -> IO RadioButton

Append a new RadioButton to the Toolbar.

See toolbarInsertNewButton for details.

Warning: this function is deprecated and should not be used in newly-written code.

toolbarPrependNewRadioButton :: (ToolbarClass self, RadioButtonClass rb) => self -> String -> Maybe (String, String) -> Maybe rb -> IO RadioButton

Prepend a new RadioButton to the Toolbar.

See toolbarInsertNewButton for details.

Warning: this function is deprecated and should not be used in newly-written code.

toolbarInsertNewWidget :: (ToolbarClass self, WidgetClass w) => self -> Int -> w -> Maybe (String, String) -> IO ()

Insert an arbitrary widget to the Toolbar.

The Widget should not be a button. Adding Buttons with the toolbarInsertButton,... functions with stock objects is much better as it takes care of theme handling.

Warning: this function is deprecated and should not be used in newly-written code.

toolbarAppendNewWidget :: (ToolbarClass self, WidgetClass w) => self -> w -> Maybe (String, String) -> IO ()

Append a new Widget to the Toolbar.

See toolbarInsertNewButton for details.

Warning: this function is deprecated and should not be used in newly-written code.

toolbarPrependNewWidget :: (ToolbarClass self, WidgetClass w) => self -> w -> Maybe (String, String) -> IO ()

Prepend a new Widget to the Toolbar.

See toolbarInsertNewButton for details.

Warning: this function is deprecated and should not be used in newly-written code.

toolbarSetOrientation :: ToolbarClass self => self -> Orientation -> IO ()

Sets whether a toolbar should appear horizontally or vertically.

toolbarGetOrientation :: ToolbarClass self => self -> IO Orientation

Retrieves the current orientation of the toolbar. See toolbarSetOrientation.

toolbarSetStyle :: ToolbarClass self => self -> ToolbarStyle -> IO ()

Alters the view of the toolbar to display either icons only, text only, or both.

toolbarGetStyle :: ToolbarClass self => self -> IO ToolbarStyle

Retrieves whether the toolbar has text, icons, or both. See toolbarSetStyle.

toolbarUnsetStyle :: ToolbarClass self => self -> IO ()

Unsets a toolbar style set with toolbarSetStyle, so that user preferences will be used to determine the toolbar style.

toolbarSetTooltips

:: ToolbarClass self
=> self
-> Bool	`enable` - set to `False` to disable the tooltips, or `True` to enable them.
-> IO ()
Sets if the tooltips of a toolbar should be active or not.

toolbarGetTooltips :: ToolbarClass self => self -> IO Bool

Retrieves whether tooltips are enabled. See toolbarSetTooltips.

type IconSize = Int

The size of an icon in pixels.

iconSizeInvalid :: IconSize

Don't scale but use any of the available sizes.

iconSizeSmallToolbar :: IconSize

Icon size for small toolbars.

iconSizeLargeToolbar :: IconSize

Icon size for larger toolbars.

toolbarSetIconSize :: ToolbarClass self => self -> IconSize -> IO ()

This function sets the size of stock icons in the toolbar. You can call it both before you add the icons and after they've been added. The size you set will override user preferences for the default icon size.

It might be sensible to restrict oneself to IconSizeSmallToolbar and IconSizeLargeToolbar.

Warning: this function is deprecated and should not be used in newly-written code.

toolbarGetIconSize :: ToolbarClass self => self -> IO IconSize

Retrieves the icon size for the toolbar. See toolbarSetIconSize.

toolbarInsert

:: (ToolbarClass self, ToolItemClass item)
=> self
-> item	`item` - a `ToolItem`
-> Int	`pos` - the position of the new item
-> IO ()
Insert a `ToolItem` into the toolbar at position `pos`. If `pos` is 0 the item is prepended to the start of the toolbar. If `pos` is negative, the item is appended to the end of the toolbar. Available since Gtk version 2.4

toolbarGetItemIndex

:: (ToolbarClass self, ToolItemClass item)
=> self
-> item	`item` - a `ToolItem` that is a child of `toolbar`
-> IO Int	returns the position of item on the toolbar.
Returns the position of `item` on the toolbar, starting from 0. It is an error if `item` is not a child of the toolbar. Available since Gtk version 2.4

toolbarGetNItems :: ToolbarClass self => self -> IO Int

Returns the number of items on the toolbar.

Available since Gtk version 2.4

toolbarGetNthItem

:: ToolbarClass self
=> self
-> Int	`n` - A position on the toolbar
-> IO (Maybe ToolItem)	returns The `n`'th `ToolItem` on the toolbar, or `Nothing` if there isn't an `n`'th item.
Returns the `n`'th item on toolbar, or `Nothing` if the toolbar does not contain an `n`'th item. Available since Gtk+ version 2.4

toolbarGetDropIndex

:: ToolbarClass self
=> self
-> (Int, Int)	`(x, y)` - coordinate of a point on the toolbar. Note that `(x, y)` are in toolbar coordinates, not window coordinates.
-> IO Int	returns The position corresponding to the point `(x, y)` on the toolbar.
Returns the position corresponding to the indicated point on toolbar. This is useful when dragging items to the toolbar: this function returns the position a new item should be inserted. Available since Gtk version 2.4

toolbarSetDropHighlightItem

:: (ToolbarClass self, ToolItemClass toolItem)
=> self
-> Maybe toolItem	`toolItem` - a `ToolItem`, or `Nothing` to turn of highlighting
-> Int	`index` - a position on the toolbar
-> IO ()
Highlights the toolbar to give an idea of what it would look like if `item` was added to toolbar at the position indicated by `index`. If `item` is `Nothing`, highlighting is turned off (and the index is ignored). The `toolItem` passed to this function must not be part of any widget hierarchy. When an item is set as a drop highlight item it can not added to any widget hierarchy or used as highlight item for another toolbar. Available since Gtk version 2.4

toolbarSetShowArrow :: ToolbarClass self => self -> Bool -> IO ()

Sets whether to show an overflow menu when the toolbar doesn't have room for all items on it. If True, items that there are not room are available through an overflow menu.

Available since Gtk version 2.4
