Hi!
I have a round area which I want to be able to move the mouse over and fire
off events... how do I do that?
I have drawn a FillPie Graphics and I feel that there has to be a way of
getting to know if the mouse is over that area since I have the coordinates
to paint the Pie but I don't know where to start or what to look for really.
Best Regard
/Lars

But a Region (GraphicsPath really) can be circular!
Dim path As New System.Drawing. Drawing2D.Graph icsPath()
path.AddEllipse (aRectangle)
So you could use either Region.IsVisibl e or GraphicsPath.Is Visible.
Borrowing your earlier code (untested):
Private Sub Button1_Click(B yVal sender As System.Object, ByVal e As
System.EventArg s) Handles Button1.Click
Dim g As Graphics
g = pBox.CreateGrap hics
cp = New Point(pBox.Size .Width / 2, pBox.Size.Heigh t / 2)
g.DrawEllipse(N ew Pen(Color.Red), New Rectangle(cp.X - 10, cp.Y -
10, 20, 20))
End Sub
Private Sub pBox_MouseMove( ByVal sender As Object, ByVal e As
System.Windows. Forms.MouseEven tArgs) Handles pBox.MouseMove
Dim path As New System.Drawing. Drawing2D.Graph icsPath
Dim cp As New Point(pBox.Size .Width / 2, pBox.Size.Heigh t / 2)
path.AddEllipse (New Rectangle(cp.X - 10, cp.Y - 10, 20, 20))
If path.IsVisible( e.X, e.Y) Then
Debug.WriteLine (e.X & " : " & e.Y)
End If
End Sub
I would probably keep a class instance variable for the outline of the
image being checked, the GraphicsPath above, then I would simply use this
variable in the MouseMove & Paint events. Depending on what the "area" is really
that the OP is wanting I would consider creating a derived control & set its
Control.Region property to the shape desired (a round Button or round
Label for example).
Hope this helps

the
OP wanted to only fire events or trigger action at least when the mouse
was
inside a defined pie chart or ( circle )

No the answer is easier than that.
You take the centre of the client area and compute.
For example, if the radius is 10 your client area is 20,20. Then the
centre point is 10,10. If x, or y is larger than the centre point +
or -
the mouse coordinates then this is out
Alternatively calculate the hypotenuse for any given point
H*H = A*A + O*O
Once you calculate the H = SQRT( A*A + O*O) you can compare this
against the Radius. to determin if the point is in.

OHM,
I would not (did not) say your were wrong! :-)
IMHO there are at least 3 ways to do every thing.
You just had a different way of seeing the problem & solving it. I used
GraphicsPath, Ken suggested Region. I also suggested creating a circular
control. I'm sure there are others, at least variations of what we all
suggested.
In case you were wondering to get a circular Region you need to start with a
circular GraphicsPath, which you pass to the constructor of the Region.
Just a thought

In a simple two form project, use a button on each form to Show() the other
form and Hide() the current form. Add MouseEnter and MouseLeave events to
both buttons so they change the image on each button when they are NOT
Clicked but the cursor enters their boundary.
This setup works fine. If the mouse cursor enters the button on the first
form the image changes and if the button is clicked the first form
disappears and the other form...

each one correlated to a specific area. Is there any scrip which can do
this?

hello,
I'm writing a panoramic image viewer in javascript. When the mouse is over
the image, I want it to be a crosshair (over most of the image), or a
hand/pointer (when it's over an image map region). The image map is
created in javascript, but doesn't set any 'cursor' style rules.
The problem I'm having is I have two images embedded inside two divs. The
outer div has style='... cursor:crosshair', but when I move over the image...

Hi all,
I'm having some trouble with the Mouse Hover/Leave events on a user
control.
Say I have a user control with a panel covering the whole control. In turn,
a label + picture box cover the panel.
If the mouse is anywhere over the user control, I want the background
colour to change.

Hi,
I couldn't find a necessary class which shows when mouse hovers on a
link in Webbrowser control.
Think of there's a status bar(text), when mouse comes on a link, the
URL must be shown in this status bar.
How can i do this?
Thanks.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
