如何在按下鼠标时跟踪鼠标输入事件 c# visual studio？

Question

我尝试实现以下目标：按下鼠标时->如果鼠标进入面板，颜色会改变当鼠标松开时 -> 鼠标进入时面板不会改变。

--问题：按下鼠标时，鼠标进入事件没有反应

我该如何解决？

//for all panels in the menu
private void walletpanel0_MouseEnter(object sender, EventArgs e)
    {
        if ( mouseDown && previousPanel != (Panel)sender)
        {
            Panel p = (Panel)sender;
            p.BackColor = Color.FromArgb(255, 26, 41, 56);

            previousPanel.BackColor = Color.FromArgb(255, 44, 62, 73);

            previousPanel = p;
         }
     }

private void walletpanel0_MouseDown(object sender, MouseEventArgs e)
    {
        mouseDown = true;
        //to select the panel when clicked on it
        if (previousPanel != (Panel)sender)
        {
            Panel p = (Panel)sender;
            p.BackColor = Color.FromArgb(255, 26, 41, 56);

            previousPanel.BackColor = Color.FromArgb(255, 44, 62, 73);

            previousPanel = p;
        }
    }

Answer 1

据我所知，按下鼠标按钮时不会触发 MouseEnter、MouseMove 和 MouseLeave 事件。释放按钮后，如果在按下按钮时鼠标移动触发订阅事件，则会触发订阅事件。

基本问题是，当 MouseDown 事件发生在 Control 上时，Control "captures" 鼠标在按下按钮之前不会释放它已发布，这意味着其他 Controls.

未收到移动事件

假设您的所有 Panels 都订阅了它，以下事件处理程序应该可以帮助您：

private void Panels_MouseMove(object sender, MouseEventArgs e)
{
    if (e.Button != MouseButtons.None)
    {
        Control control = (Control)sender;

        if (control.Capture)
            control.Capture = false;
    }
}
