Hi there,

I have created an owner draw menu item using DrawItem and MeasureItem in
VB.NET. This seems to work well. I was wondering how I can do mouse over
effects in these menus. Basically the same as the dot net menus where they
get highlighted when the mouse moves over them.

Does anyone have any VB dot net examples or suggestions on how I could do
this?

Thanks
Devron
 
How do I handle the mouse_leave event to know when the mouse leaves the
item.?

Thanks
Devron
 
Hi Devron, You don't want to be looking at those events, you need to be
using the Draw Item event.

Inside the draw item even, we have the 'e' class (declared as
DrawItemEventArgs) and it allows you to draw the item depending on the state
of the item:

' /// Inside DrawItem

If (e.State And DrawItemState.Selected) = DrawItemState.Selected Then
' The item is currently selected, fill with blue
Else
' The item is not selected, fill with white
End If

'///

' /// Inside DrawItem
If (e.State And DrawItemState.Selected) = DrawItemState.Selected Then
' The item is currently selected, fill with blue
Else
' The item is not selected, fill with white
End If

'///

For the TopLevel Menus(File, Edit etc...) you may also want to check for
DrawItemState.Hotlight.

' /// Inside DrawItem

If (e.State And DrawItemState.Selected) = DrawItemState.Selected Then
' The item is currently selected, fill with blue
ElseIf (e.State And DrawItemState.HotLight) = DrawItemState.Selected Then
'The Item is currently Hot, fill with yellow
Else
' The item is not selected or hot, fill with systemcolors.menu
End If

'///
 
Hi Mick, slight error in your code:
If (e.State And DrawItemState.Selected) = DrawItemState.Selected Then
' The item is currently selected, fill with blue
Click to expand...

' /// Slight error
ElseIf (e.State And DrawItemState.HotLight) = DrawItemState.Selected Then
Click to expand...
' ///
'The Item is currently Hot, fill with yellow
Else
' The item is not selected or hot, fill with systemcolors.menu
End If
Click to expand...

It should read

' ///
ElseIf (e.State And DrawItemState.HotLight) = DrawItemState.HotLight Then
' ///

Well spotted. That's what happens when you cut/paste and edit without
checking.
Of course, had I done this in VS.Net I would have instantly noticed it.
