J'essaie de déplacer le contrôle nommé pictureBox1 en le faisant glisser. Le problème est que, lorsqu'il se déplace, il continue de se déplacer d'un endroit à un autre autour de la souris, mais il le suit ... C'est mon code. et j'apprécierais vraiment si vous pouviez m'aider
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
bool selected = false;
private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
{
selected = true;
}
private void pictureBox1_MouseMove(object sender, MouseEventArgs e)
{
if (selected == true)
{
pictureBox1.Location = e.Location;
}
}
private void pictureBox1_MouseUp(object sender, MouseEventArgs e)
{
selected = false;
}
}
Tout ce dont tu as besoin:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private Point MouseDownLocation;
private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == System.Windows.Forms.MouseButtons.Left)
{
MouseDownLocation = e.Location;
}
}
private void pictureBox1_MouseMove(object sender, MouseEventArgs e)
{
if (e.Button == System.Windows.Forms.MouseButtons.Left)
{
pictureBox1.Left = e.X + pictureBox1.Left - MouseDownLocation.X;
pictureBox1.Top = e.Y + pictureBox1.Top - MouseDownLocation.Y;
}
}
}
essayez ceci pour déplacer le contrôle pictureBox lors de l'exécution en utilisant la souris
private void pictureBox7_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
xPos = e.X;
yPos = e.Y;
}
}
private void pictureBox7_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e)
{
PictureBox p = sender as PictureBox;
if (p != null)
{
if (e.Button == MouseButtons.Left)
{
p.Top += (e.Y - yPos);
p.Left += (e.X - xPos);
}
}
}
Vous pouvez également utiliser l'extension:
public static class CmponentsExtensions
{
//Management of mouse drag and drop
#region Menu and Mouse
private static bool mouseDown;
private static Point lastLocation;
/// <summary>
/// To enable control to be moved around with mouse
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="control"></param>
public static void moveItselfWithMouse<T>(this T control) where T: Control
{
control.MouseDown += (o, e)=> { mouseDown = true; lastLocation = e.Location; };
control.MouseMove += (o, e) =>
{
if (mouseDown)
{
control.Location = new Point((control.Location.X - lastLocation.X) + e.X, (control.Location.Y - lastLocation.Y) + e.Y);
control.Update();
}
};
control.MouseUp += (o, e) => { mouseDown = false; } ;
}
public static void moveOtherWithMouse<T>(this T control, Control movedObject) where T : Control
{
control.MouseDown += (o, e) => { mouseDown = true; lastLocation = e.Location; };
control.MouseMove += (o, e) =>
{
if (mouseDown)
{
movedObject.Location = new Point((movedObject.Location.X - lastLocation.X) + e.X, (movedObject.Location.Y - lastLocation.Y) + e.Y);
movedObject.Update();
}
};
control.MouseUp += (o, e) => { mouseDown = false; };
}
#endregion
}
Ensuite, vous devez l'utiliser avec un certain contrôle:
Dans ce cas, pictureBox1 a déplacé le formulaire entier
pictureBox1.moveOtherWithMouse(this);
Dans ce cas, vous déplacez uniquement la PictureBox:
pictureBox1.moveItselfWithMouse();
