B4J Question How to set TreeViewItem colour and or Font

[Mashiane]

Hi There

I want to change the colour of my treeview items depending on some settings, is there a way to achieve that with CSSUtils?

Also if possible change the treeview font? italic, bold etc

Simple example, probably better ways to do it (cell factory etc)

Dim treev As TreeView
Dim titem As TreeItem
treev.Initialize("")
titem.Initialize("","one")
treev.Root.Children.Add(titem)
MainForm.RootPane.AddNode(treev,0,0,-1,-1)
Dim titem2 As JavaObject ' can't use b4j treeitem as we want a label not string
Dim lab As Label
lab.Initialize("")
lab.Text = "two"
If lab.Text = "two" Then
CSSUtils.SetStyleProperty(lab,"-fx-text-fill","red")
CSSUtils.SetStyleProperty(lab,"-fx-font-style","italic")
Else
CSSUtils.SetStyleProperty(lab,"-fx-text-fill","black")
CSSUtils.SetStyleProperty(lab,"-fx-font-style","normal")
End If
titem2.InitializeNewInstance("javafx.scene.control.TreeItem",Array(lab))
titem.Children.Add(titem2)

Wow, thanks, what happens if the item is an already existing treeItem and was not created this way?

I think you will get an error as CSSUtils cant change style of String.
