B4J Question Simple Custom listview example?

[aidymp]

Hi I want to add images to a list view in B4J, looking in the forum I cannot see one example of doing this simply, I have seen the example that loads images from a webpage, and does what I want, but I just add local images and 2 lines of text, the examples seem too busy for me to see the actual basic code to do this!

I was hoping I could use a sub like so

Sub addline(image as image, line1 as string, line2 as string)
...
End sub

Thanks

You can design a layout with Designer(you can do it also coding): a Panel with an imageview and two labels, load into a panel, and populate the listview with the panels

At this example (extracted from one of my applications), you have one Webview and two labels

Private Lstgroupsel as Listview
Private Wbvgroup as Webview
Private lstpicartistmed as List
Private Lbltxtgrup, Lbltxtsong as Label

For i=0 To lstartist.Size-1
                    
       Dim p As AnchorPane
       p.Initialize("")
       p.LoadLayout("lstlaygroup")       'Load the layout designed at Internal Designer
                   
       Lbltxtgrup.Text = "artist " & i
       Lbltxtsong.Text = "song " & i
       Wbvgroup.LoadUrl(lstpicartistmed.Get(i))     'Load the Url at item i of the list lstpicartistmed
       Wbvgroup.Style="-fx-effect: dropshadow(three-pass-box,rgba(0,0,0,0.8),15,.00,5,8);"
       Lstgroupsel.Items.Add(p)     'Add the panel to the listview
                   
Next

Thank you, So you design one element of the list view, and then for each item you add, it adds a duplicate of the panel you created?

-- EDIT This maybe where I am getting confused, as the examples all use forms created with the old version of B4J that uses SceneBuilder, and I dont have this installed as I don't use it! So was just expecting the examples to work when i copied subs from them to my own program!

Thanks again

Each element of the listview is a panel (each with an Webview with different URL, and two labels, each with different text on each panel)

See the example attached

Thank you so much, that is excellent, and I can seen that you design the list view element in the designer! which as I was not using scenebuilder and either missed, or it wasn't made clear in the documentation that you do it that way, so i was using code with no actual form lol! Thanks again you are a credit to the community.
