How to Programmatically add or remove items in ListBox FORM control

Question

I am having a problem with OpenOffice.org ListBox Form control. I have built a small form (not dialog) that contains a textbox and ListBox and 2 buttons.

Sub AddToList_ButtonClicked()

Dim oThisDoc As Object
Dim oForms as Object
Dim oForm as Object 

oThisDoc = thisComponent.getDrawPage()
oForms = oThisDoc.getForms()
oForm = oForms.getByName("SimpleForm")

Dim oTextBox As Object
Dim oListBox As Object

oListBox = oForm.getByName("simpleListBox")
oTextBox = oForm.getByName("simpleTextBox").Text
oListBox.stringitemlist() = Array("One", "Two", "Three") '<--- Only possible way to add items to the ListBox Form Control :(

End Sub

Sub RemoveFromList_ButtonClicked()

Dim oThisDoc As Object
Dim oForms as Object
Dim oForm as Object 

oThisDoc = thisComponent.getDrawPage()
oForms = oThisDoc.getForms()
oForm = oForms.getByName("SimpleForm")

Dim oListBox As Object

oListBox = oForm.getByName("simpleListBox")

oListBox.stringitemlist()  '<--- contains array of items
oListBox.SelectedItems '<--- contains items selected for removal

End Sub

I would totally appreciate any solution for this problem!.

Answer 1

Is this what you are looking for?

' Add items.
oListBox.StringItemList() = Array("One", "Two", "Three")
oListBox.insertItemText(oListBox.ItemCount, "Four")  ' This works even if oListBox starts out empty.
oListBox.insertItemText(oListBox.ItemCount, "Five")

' Remove the last item in the list.
oListBox.removeItem(oListBox.ItemCount - 1)

XrayTool shows that oListBox implements XItemList.

The form I used to test this code was in Writer, without any connection to Base.
