Hi - this was posted last weekend and unfortunately not resolved. The
solutions that were posted almost worked but after another 5 days of
working on the code everynight, I am not further ahead.
If you do have any ideas I would really like to hear them.
Thanks
Colin

I want a glorified popup/context menu on a button that shows only when
the mouse button is pressed over the button, and disappears when the
mouse button is released anywhere. Here's a full description.

When the mouse button is depressed over Button1, I want the
popup form (an instance of formPopup) to show. If the mouse
button is released anywhere, the cursor could be anywhere,
even over another application or on the desktop or somewhere else,
I want the popup form to be hidden. The code I have means that
if I move the cursor away from the display form, then release
the mouse button, the form isn't always hidden. I also want
to trap various events in the instance of formPopup, such as
mouseenter etc for controls on that form. By adding
Button1.Capture=True, no events in the instance of formPopup
can be caught.

Colin


Here is the full code I already have.

1. Launch Visual Studio .Net 2003 and create a new winforms
application.
2. Use the VS IDE toolbar to put a new button, Button1, on the form.
3. Paste in the following code

Public Class Form1
Inherits System.Windows.Forms.Form

//and include the Windows Form Designer Code in here

Public Class formPopup
Inherits System.Windows.Forms.Form

Private Sub formPopup_Load(ByVal sender As Object, _
ByVal e As System.EventArgs) Handles MyBase.Load
Dim b1 As New Button
b1.Size = New Size(15, 15)
b1.Location = New Point(10, 10)
b1.BackColor = Color.Gray
Me.Controls.Add(b1)
AddHandler b1.MouseEnter, AddressOf subMEnter
AddHandler b1.MouseLeave, AddressOf subMLeave
AddHandler b1.MouseUp, AddressOf subMUp

Dim b2 As New Button
b2.Size = New Size(15, 15)
b2.Location = New Point(30, 10)
b2.BackColor = Color.Gray
Me.Controls.Add(b2)
AddHandler b2.MouseEnter, AddressOf subMEnter
AddHandler b2.MouseLeave, AddressOf subMLeave
End Sub

Private Sub subMUp(ByVal sender As Object, _
ByVal e As MouseEventArgs)
Debug.WriteLine("MouseUp")
End Sub

Private Sub subMLeave(ByVal sender As Object, _
ByVal e As EventArgs)
Dim b As Button = CType(sender, Button)
b.BackColor = Color.Gray
End Sub

Private Sub subMEnter(ByVal sender As Object, _
ByVal e As EventArgs)
Dim b As Button = CType(sender, Button)
b.BackColor = Color.Blue
End Sub
End Class


Dim WithEvents f As formPopup

Private Sub Button1_MouseDown(ByVal sender As Object, _
ByVal e As System.Windows.Forms.MouseEventArgs) _
Handles Button1.MouseDown
Debug.WriteLine("Button1_MouseDown")
f = New formPopup

f.Size = New Size(80, 80)
f.BackColor = Color.Yellow

f.Show()
'Button1.Capture = True 'Have to comment this or else I cannot
'trap mouse trap events for controls on the
form
End Sub

Private Sub Button1_MouseUp(ByVal sender As Object, _
ByVal e As System.Windows.Forms.MouseEventArgs) _
Handles Button1.MouseUp, f.MouseUp
Debug.WriteLine("Button1_MouseUp")
f.Close()
f.Hide()
f = Nothing
End Sub
End Class

AFAIR I suggested to use

f.capture = true

instead of

button1.capture = true

in my last reply.
 
Armin:
I too thought this was done and dusted. Looking at
the original thread it appears he also wants to
trap button events on the popup form.


Colin:
Try this (the code is below). The key code is in
formPopup_MouseLeave. If I understand the user
interface you are describing, you must have a really
good reason for wanting to code this behaviour. For
what it's worth, I find it annoying and not something
I would put into any of my applications.

Note that MouseLeave is not the only way to 'leave'
a control ! You will need to make it more robust.

Try this out Colin. It worked when I tried it. You need to set the button
capture to True. Then create a rect of the button to see if the point is in
or out of the button. Also, why do you have Button1_MouseUp handling the
f.mouseup? Remove it and it will work.


Private Sub Button1_MouseDown(ByVal sender As Object, _
ByVal e As System.Windows.Forms.MouseEventArgs) _
Handles Button1.MouseDown
Debug.WriteLine("Button1_MouseDown")
f = New formPopup()

f.Size = New Size(80, 80)

f.Show()

'-- You NEED to set this to true!
Button1.Capture = True

End Sub



Private Sub Button1_MouseUp(ByVal sender As Object, ByVal e As

rid of this. Why is this here?

Brian, I'm not sure your code does exactly what he wants. This is the
confusion I think: from his posting I believe he wants to "select" buttons
on the popup form while the mouse button is down, and further only display
the popup form while the mouse button is down. If the mouse button is ever
released, regardless of where it is, then the popup form is hidden/disposed
of.

Colin, could you reply to confirm your exact desired behaviour please.

Hexathioorthooxalate
 
What? How do you select another button when the a button is already down?
You have to release the button before you can select another. It seems to me
like he's trying to create a custom popup menu that works like the standard
Cut/Paste/SelectAll menu but with buttons. Is this right?

Yes - I think he is wanting something like this although clearly as we can
both see, he can't select the button via normal button clicks. I think it
explains why he says he wants to capture MouseOver events for controls on
the popup form, rather than click events.

I'm still waiting for Colin to repost and confirm exactly what he wants.

Ok, let's try this. This acts like a context menu with buttons. If this
isn't it, I don't know what he wants.

This looks good, he has more than enough to work with now.

I sent him through an eMail message a few hours ago but it's a dummy account
he probably uses to control spam (it was rejected). I look forward to him
replying confirming the detail.

I did want to select buttons while the mouse button was down. I did
want the popup to disappear whenever the mouse button was released.
What Brian has written behaves more like a slick Windows programme and
this is what I will use. What Hex has written is what I asked for. I
asked for the wrong thing :(

Thank you both again

Colin,

I went and read your first post and finally figured out what you wanted
(should have done that in the first place). Place this into your form mouse
up event: It will handle the mouse up event as long as the mouse is within
the form. I haven't figured it out (yet) when the mouse is off the form. It
will get you 90% where you what to be, i think.
