Graphics.UI.Gtk.MenuComboToolbar.Toolbar

Create bars of buttons and other widgets

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 -> StockId -> 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.

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).

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

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.

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

Retrieves the icon size for the toolbar. See toolbarSetIconSize.

:: (ToolbarClass self, ToolItemClass item)

=> self

Arguments

:: (ToolbarClass self, ToolItemClass toolItem)

=> self

-> Maybe toolItem

toolItem - a ToolItem, or Nothing to turn of highlighting

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

onPopupContextMenu

Arguments

:: ToolbarClass self

=> self

-> (Int -> Int -> Int -> IO Bool)

(x y button -> ...) - The handler should return True if the signal was handled, False if not.

-> IO (ConnectId self)

afterPopupContextMenu

Arguments

:: ToolbarClass self

=> self

(x y button -> ...) - The handler should return True if the signal was handled, False if not.

Emitted when the user right-clicks the toolbar or uses the keybinding to display a popup menu.

Application developers should handle this signal if they want to display a context menu on the toolbar. The context-menu should appear at the coordinates given by x and y. The mouse button number is given by the button parameter. If the menu was popped up using the keybaord, button is -1.
