如何以编程方式添加或删除ListBox FORM控件中的项目

Question

我遇到OpenOffice.org ListBox Form控件的问题。 我已经构建了一个包含文本框和ListBox以及2个按钮的小表单（不是对话框）。

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

我完全赞赏这个问题的任何解决方案！。

Answer 1

这是你在找什么？

' 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表明oListBox实现了XItemList。

我用来测试此代码的表单是在Writer中，没有任何与Base的连接。
