SUMMARY
=======
The Microsoft Windows Common Controls OCX (COMCTL32.OCX) provides a ToolBar
control and a StatusBar control that you can easily implement in your Visual
Basic application. There is no built-in method to synchronize these two controls
such that the StatusBar displays descriptive text for a ToolBar button when the
mouse is currently located over it. This article illustrates how you can
implement this behavior within your Visual Basic application.
MORE INFORMATION
================
Some applications, such as Microsoft PowerPoint, Word, and Excel, will not only
display a helpful tip when the mouse hovers over a ToolBar button, but will also
display more descriptive text in the StatusBar to give the user a definition of
the button's function. Although this feature is not built into the Toolbar and
StatusBar controls in COMCTL32.OCX, there are ways to mimic its effect in a
Visual Basic application as described in the following sample.
Steps to Create Sample
----------------------
1. Create a new Visual Basic project. Form1 is created by default.
2. Select Components from the Projects menu, check "Microsoft Windows Common
Controls" and Click OK.
3. Add a ToolBar control to Form1.
4. Add a StatusBar control to Form1.
5. Insert two buttons on the ToolBar by right-clicking the ToolBar control,
selecting "Properties," and then the selecting the Buttons Tab.
6. For the first button, Click "Insert Button" and set these properties:
Property Value
-------- -----
Tag Opens a File
ToolTipText Open
7. For the second button, Click "Insert Button" and set these properties:
Property Value
-------- -----
Tag Closes a File
ToolTipText Close
8. Right-click the StatusBar control and click Properties. Click the Panels tab
and set the AutoSize property of the first panel to "1-sbrSpring."
9. Paste the following code into Form1's code window:
Private Sub Form_MouseMove(Button As Integer, _
Shift As Integer, X As Single, Y As Single)
StatusBar1.Panels(1).Text = "" ' Clear when not over ToolBar
End Sub
Private Sub Toolbar1_MouseMove(Button As Integer, _
Shift As Integer, x As Single, y As Single)
Dim Found As Boolean
Dim ToolBarButton As Variant
Dim Index As Long
'Loop through all buttons on the toolbar
For Index = 1 To Toolbar1.Buttons.Count
'Set reference to button
Set ToolBarButton = Toolbar1.Buttons(Index)
'Check if mouse is positioned over button
If (x > ToolBarButton.Left) And _
(x < (ToolBarButton.Left + ToolBarButton.Width)) And _
(y > ToolBarButton.Top) And _
(y < (ToolBarButton.Top + ToolBarButton.Height)) Then
'Mouse is over button. Now to avoid screen flickering,
'check if StatusBar needs updating
If StatusBar1.Panels(1).Text <> ToolBarButton.Tag Then
StatusBar1.Panels(1).Text = ToolBarButton.Tag
End If
'Set flag indicating a button was found
Found = True
'Button has been found, discontinue loop
Exit For
End If
Next
If Not Found Then
StatusBar1.Panels(1).Text = ""
End If
End Sub
10. Save and run the sample project. Move the mouse over the two buttons on the
ToolBar, and note that the appropriate text will be displayed in the
StatusBar's panel depending on which button, if any, the mouse is positioned
over.
