TreeView MouseOver Node

Hello!

Perhaps theres someone in the who is able to help me .....

I use a TreeView (MS Common Controls 5.0 (SP2)), and it works fine so far.

But: I need something witch displays Fond.Underlined and a Userdefined MouesIcon when the Users Mousepointer is over a spezified Node of the TreeView.

This is what i have done so far:
(Makes the spezified Node selected)

Code:

---

Private Sub tvwModule_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)

    Dim nodX As Node
    Set nodX = tvwModule.HitTest(X, Y)

    If Not nodX Is Nothing Then
        If Not nodX.Parent Is Nothing Then
            If Not nodX.Child Is Nothing Then
            Else
                ' Only BabyNode will be selected
                nodX.Selected = True
            End If
        End If
    End If

    Set nodX = Nothing
   
End Sub

---

There is a second Problem I cant resolve:
(Maybe Simple)

How do I make sure the TreeView first Row is displayed, even when the TreeView has Scrollbars?
Right now it seems the TreeViews Scrollbars are scrolled to the middle of the TreeView, I want them at the Begin of the Control, e.G. at TreeViews Top and Left.

Any ideas?

Thanks in Advanced,

MyVar.

This is to answer the second part.

dim nd as node
set nd = tvtreeview.nodes(1)
nd.select = true
nd.ensurevisible = true

Thx, Dalceon. The second Problem is resolved. It works fine that Way.

I just made some adjustments:

Code:

---

    tvwModule.Nodes.Item(1).Selected = True
    Set nodX = tvwModule.Nodes(1)
    nodX.Selected = True
    nodX.EnsureVisible

---

Now, some Ideas for the Primary Problem?

Thanks in Advance,

MyVar.

this does most of what you want.
without getting into some very complicated stuff, you can't underline individual items as far as I know.
be sure to set the mouseicon under the picture tab of the properties page.

let me know if this is what you need.

VB Code:

Option Explicit
Dim previousnodx As Node
 
 
Private Sub Form_Load()
Dim i As Long
Dim nd As Node
Dim x As Integer
Dim nd2 As Node
 
 
For i = 1 To 10
   Set nd = tvwModule.Nodes.Add(, , , "Number " & i)
   For x = 1 To 3
      Set nd2 = tvwModule.Nodes.Add(nd, tvwChild, , "Child " & x)
   Next
Next
 
End Sub
 
Private Sub tvwModule_MouseMove(Button As Integer, Shift As Integer, x As Single, Y As Single)
 
    Dim nodX As Node
    Set nodX = tvwModule.HitTest(x, Y)
    If Not nodX Is Nothing Then
        If Not previousnodx Is Nothing Then
           previousnodx.Bold = False
        End If
        Set previousnodx = nodX
        If nodX.Parent Is Nothing Then
              tvwModule.MousePointer = ccArrow
                nodX.Bold = False
                 LockWindowUpdate 0&
            Else
                ' Only BabyNode will be selected
                nodX.Selected = True
                tvwModule.MousePointer = 99
                nodX.Bold = True
                 LockWindowUpdate 0&
            End If
    Else
       tvwModule.MousePointer = ccArrow
    End If
    Set nodX = Nothing
    
End Sub

Thanks Dalceon!

This is not exactly what I am looking for but I like it!

I have made some Adjustments, because .Bold didnt worked for me and *OhHowLuckyIam* there is no flickering, so I cleared out LockWindowUpdate.

Since I have a 3 Dimension TreeView:

+Root
||
|+Child
||
|||+Babys
|
+Root
||
|+Child
|
+Root
||
|+Child
||
|||+Babys
|
+Root

and using Common Controls 5.0 SP2, this workes for me:

Code:

---

Private Sub tvwModule_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)

    Dim nodX As Node
    Set nodX = tvwModule.HitTest(X, Y)

    If Not nodX Is Nothing Then
        tvwModule.MousePointer = ccArrow
        If Not nodX.Parent Is Nothing Then
            tvwModule.MousePointer = ccArrow
            If Not nodX.Child Is Nothing Then
                tvwModule.MousePointer = ccArrow
            Else
                tvwModule.MousePointer = 99
                tvwModule.MouseIcon = LoadPicture(App.Path & _
                                  "\" & "Ressourcen\handkleinweiss.cur")
            End If
        End If
        nodX.Selected = True
    Else
      tvwModule.MousePointer = ccArrow
    End If
    Set nodX = Nothing
   
End Sub

---

Now each Node is Selected when the Mousepointer moves over them, but only over BabyNodes the MouseIcon is a WhiteHand.

If you wanna see how it looks like now

While only behind BabyNodes there is Code to be performed, this is a good Way to improve usability.

It would be nice to show the BabyNodes Underlined, mabe there is a Way to do it simply? I do not wanna use 3.Party Components or a Ton of API Calls.

If not, no Matter what. : )
