列表框事件触发异常
|
我糊涂了。我基本上是想告诉用户何时单击列表框中的某些内容，按住按钮并离开列表框。这是我正在做的事情的一个愚蠢的版本：
private bool itemHeld;
private void listOriginal_MouseDown(object sender, MouseEventArgs e)
{
itemHeld = true;
}
private void listOriginal_MouseUp(object sender, MouseEventArgs e)
{
itemHeld = false;
}
private void listOriginal_MouseLeave(object sender, EventArgs e)
{
if (itemHeld)
MessageBox.Show(\"OHH YEAH\");
}
没有找到相关结果

private void listBox1_MouseMove(object sender, MouseEventArgs e) { if (e.X > listBox1.Width - 1 || e.Y > listBox1.Height - 1 || e.X < 0 || e.Y < 0) { Console.WriteLine(\"drag out\"); } else Console.WriteLine(\"mouse move {0}/{1}\", e.X, e.Y); }犁攀富
private void button1_MouseLeave(object sender, EventArgs e) { Debug.WriteLine(\"Mouse leave\"); } private void button1_MouseEnter(object sender, EventArgs e) { Debug.WriteLine(\"Mouse enter\"); } private void button1_MouseHover(object sender, EventArgs e) { Debug.WriteLine(\"Mouse hover\"); }济畦刨
itemHeld = true; itemHeld = false; if(itemHeld) MessageBox.Show(\"yay\");
