通过在C＃中使用鼠标拖动控件来移动控件
我试图通过拖动它来移动名为pictureBox1的控件。 问题是，当它移动时，它会一直从一个位置移动到鼠标周围的另一个位置，但它确实跟着它…这是我的代码。 如果你能帮助我，我真的很感激
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; } }
一切你需要的：
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 = eX + pictureBox1.Left - MouseDownLocation.X; pictureBox1.Top = eY + pictureBox1.Top - MouseDownLocation.Y; } } }
尝试使用鼠标在运行时移动pictureBox控件
