# SFWidgets.ToolbarButton service

The ToolbarButton service allows to retrieve information related to the toolbar buttons available in a given toolbar. With this service it is possible to:

- Toggle the visibility of toolbar elements.

- Execute the command associated with a given toolbar button.

## Service invocation

Before using the ToolbarButton service the ScriptForge library needs to be loaded or imported:

• Basic macros require to load ScriptForge library using the following statement:
GlobalScope.BasicLibraries.loadLibrary("ScriptForge")
• Python scripts require an import from scriptforge module:
from scriptforge import CreateScriptService

The ToolbarButton service is invoked using the ToolbarButtons method from the Toolbar service.

##### In Basic

The example below retrieves the names of all buttons available in the Standard toolbar.

        oDoc = CreateScriptService("Document", ThisComponent)
        oToolbar = oDoc.Toolbars("standardbar")
        arrToolbarButtons = oToolbar.ToolbarButtons()
        MsgBox SF_String.Represent(arrToolbarButtons)

Use the ToolbarButtons method without arguments to retrieve an array with all available toolbar button names.

The example below toggles the visibility of the Print button in the Standard toolbar:

        oDoc = CreateScriptService("Document", ThisComponent)
        oToolbar = oDoc.Toolbars("standardbar")
        oToolbarButton = oToolbar.ToolbarButtons("Print")
        oToolbarButton.Visible = Not oToolbarButton.Visible

The button name passed as argument to the ToolbarButtons method is the localized button name defined in the Tools - Customize - Toolbars dialog.

Inactive toolbars do not have buttons. Therefore, calling the ToolbarButtons method will make the toolbar visible.

##### In Python

        bas = CreateScriptService("Basic")
        doc = CreateScriptService("Document", bas.ThisComponent)
        toolbar = doc.Toolbars("standardbar")
        arr_toolbar_buttons = toolbar.ToolbarButtons()
        bas.MsgBox(repr(arr_toolbar_buttons))

        bas = CreateScriptService("Basic")
        doc = CreateScriptService("Document", bas.ThisComponent)
        toolbar = doc.Toolbars("standardbar")
        toolbar_button = toolbar.ToolbarButtons("Print")
        toolbar_button.Visible = not toolbar_button.Visible

## Use of ToolbarButton alongside the PopupMenu service

A common use case of the properties X and Y described above is to open a popup menu in the position where the toolbar button is located.

Suppose you create the script below and associate it with a button named "My Button" in the standardbar. When it is clicked, a popup menu will be shown with 3 options for the user to select.

##### In Basic

        Sub OpenPopupMenu()
            GlobalScope.BasicLibraries.LoadLibrary("ScriptForge")
            oDoc = CreateScriptService("Document", ThisComponent)
            oToolbar = oDoc.Toolbars("standardbar")
            oButton = oToolbar.ToolbarButtons("My Button")
            oPopup = CreateScriptService("SFWidgets.PopupMenu", , oButton.X, oButton.Y + oButton.Height)
            oPopup.AddItem("Item A", "A")
            oPopup.AddItem("Item B", "B")
            oPopup.AddItem("Item C", "C")
            strResponse = oPopup.Execute(False)
            MsgBox "Your choice: " & strResponse
        End Sub

##### In Python

        def open_popup_menu(args=None):
            bas = CreateScriptService("Basic")
            doc = CreateScriptService("Document", bas.ThisComponent)
            toolbar = doc.Toolbars("standardbar")
            toolbutton = toolbar.ToolbarButtons("My Button")
            popup = CreateScriptService("PopupMenu", None, toolbutton.X, toolbutton.Y + toolbutton.Height)
            popup.AddItem("Item A", "A")
            popup.AddItem("Item B", "B")
            popup.AddItem("Item C", "C")
            response = popup.Execute(False)
            bas.MsgBox(f"Your choice: {response}")
