Hello,

How do you create a ToolBar (AKA ButtonBar) in B4J using all code (not using Screen Builder that is)?


Thanks,

Michael

Hi,

one possible solution using JavaObject Library.
Call CreateToolBar in f.e. AppStart after MainForm.Show.

B4X:
Sub CreateToolBar
    Dim joToolBar As JavaObject
    Dim B1 As Button:B1.Initialize("B1"):B1.Text="Button 1":B1.TextColor=fx.Colors.Red
    Dim B2 As Button:B2.Initialize("B2"):B2.Text="Button 2":B2.TextColor=fx.Colors.Blue
    joToolBar.InitializeNewInstance("javafx.scene.control.ToolBar", Null)
    joToolBar.RunMethodJO("getItems", Null).runMethod("add", Array(B1))
    joToolBar.RunMethodJO("getItems", Null).runMethod("add", Array(B2))
    joToolBar.RunMethod("setStyle", Array("-fx-background-color: yellow;"))
    MainForm.RootPane.AddNode(joToolBar, 10, 10, 300, 50)
End Sub

Sub B1_Action
    Log("Button1 clicked") 
End Sub

Sub B2_Action
    Log("Button2 clicked") 
End Sub

Rob thanks that is great!!!

One follow on question please. Upon a MainForm_Resize event what code would I use to resize the Toolbar width to the new MainForm.Width?

Thanks so much!
