Vb.net mouse double click event for button [duplicate] - vb.net

Question

Rather than making an event occur when a button is clicked once, I would like the event to occur only when the button is double-clicked. Sadly the double-click event doesn't appear in the list of Events in the IDE.
Anyone know a good solution to this problem? Thank you!

Answer 1

No the standard button does not react to double clicks. See the documentation for the Button.DoubleClick event. It doesn't react to double clicks because in Windows buttons always react to clicks and never to double clicks.
Do you hate your users? Because you'll be creating a button that acts differently than any other button in the system and some users will never figure that out.
That said you have to create a separate control derived from Button to event to this (because SetStyle is a protected method)
public class DoubleClickButton : Button
{
public DoubleClickButton()
{
SetStyle(ControlStyles.StandardClick | ControlStyles.StandardDoubleClick, true);
}
}
Then you'll have to add the DoubleClick event hanlder manually in your code since it still won't show up in the IDE:
public partial class Form1 : Form {
public Form1() {
InitializeComponent();
doubleClickButton1.DoubleClick += new EventHandler(doubleClickButton1_DoubleClick);
}
void doubleClickButton1_DoubleClick(object sender, EventArgs e) {
}
}

Answer 2

Use this. Code works.
public class DoubleClickButton : Button
{
public DoubleClickButton()
{
SetStyle(ControlStyles.StandardClick |
ControlStyles.StandardDoubleClick, true);
}
}
DoubleClickButton button = new DoubleClickButton();
button.DoubleClick += delegate (object sender, EventArgs e)
{
//codes
};

i used to add MouseDoubleClick event on my object like:
this.pictureBox.MouseDoubleClick += new System.Windows.Forms.MouseEventHandler(this.pictureBox_MouseDoubleClick);

Answer 4

A double click is simply two regular click events within a time t of each other.
Here is some pseudo code for that assuming t = 0.5 seconds
button.on('click' , function(event) {
if (timer is off or more than 0.5 milliseconds)
restart timer
if (timer is between 0 and 0.5 milliseconds)
execute double click handler
})
