How to check if mouse is over a button in wpf


Before I start, I have to say this. I have read this question. And I dont see how its a duplicate of this question that I posted a few hours ago.

My original post as it is:

I am using a few buttons in WPF for displaying images from various folders. The Click mode for all the buttons is Hover. For some button, after hovering, it is routed to a function OnButtonClick. What I want to do is, ONLY after the mouse is over the button for X seconds, the processing inside the function OnButtonClick should be done.

XAML Code:

    <Button Name="Dresses" MouseEnter="onMouseEnter" MouseLeave="onMouseLeave" Content="Dresses" Grid.Row="2" Height="25" Width="85" VerticalAlignment="Center" Grid.Column="5"  FontFamily="Tahoma" FontSize="14" FontWeight="Bold" HorizontalAlignment="Center" Cursor="Hand" ClickMode="Hover">
        <Button.Background>
            <LinearGradientBrush>
                <GradientStop Color="Yellow" Offset="0" />
                <GradientStop Color="Green" Offset="1" />
            </LinearGradientBrush>
        </Button.Background>
    </Button>

C# Code:

    private void OnButtonClickDresses(object sender, RoutedEventArgs e)
    {
            //Code for delay

            //Code which should run only if mouse on button after 5 seconds

    }

PS: I am a beginner in WPF and C#. So if you can post a minimum working example I'd be actually very grateful.


Solution

  • Here is a sample application for you.

    using System.Windows.Threading;
    
    namespace MyWPF App
    {
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    
    public partial class MainWindow : Window
    {
    
        DateTime dt;
        DispatcherTimer t;
    
        public MainWindow()
        {
    
            InitializeComponent();
            t = new DispatcherTimer();
            t.Tick += new EventHandler(t_Tick);
    
        }
        private void button1_MouseEnter(object sender, MouseEventArgs e)
        {
            dt=DateTime.Now;
            t.Interval = new TimeSpan(0, 0, 1);
            t.IsEnabled = true;
    
    
        }
    
        void t_Tick(object sender, EventArgs e)
        {
    
            if ((DateTime.Now - dt).Seconds >= 5)
            {
                MessageBox.Show("Hello");// Here you can put your code which you want to execute after 5 seconds.
            }
    
        }
    
        private void button1_MouseLeave(object sender, MouseEventArgs e)
        {
            t.IsEnabled = false;
        }
    }
    
    }
