Question

我正在创建一个测试C＃WinForm应用程序，我有一个关闭按钮。将鼠标悬停在按钮上时，BackColor会变为较浅的颜色。当您停止在其上方悬停时，该按钮会变回背景颜色。单击该按钮后，它将变为白色，放开后，将更改为背景颜色。我的问题是，如果有人盘旋并且它改变了悬停颜色，那么有人点击并再次更改颜色，如果他们将鼠标拖离按钮，我可以将其更改回悬停颜色吗？

代码：

    public Form1()
    {
        InitializeComponent();
        bunifuImageButton1.MouseEnter += bunifuImageButton1_MouseHover;
        bunifuImageButton1.MouseLeave += bunifuImageButton1_MouseLeave;
        bunifuImageButton1.MouseDown += bunifuImageButton1_MouseDown;
        bunifuImageButton1.MouseUp += bunifuImageButton1_MouseUp;
    }

    private void bunifuImageButton1_MouseHover(object sender, EventArgs e)
    {
        bunifuImageButton1.BackColor = SystemColors.Highlight;
    }

    private void bunifuImageButton1_MouseLeave(object sender, EventArgs e)
    {
        bunifuImageButton1.BackColor = SystemColors.HotTrack;
    }

    private void bunifuImageButton1_MouseDown(object sender, EventArgs e)
    {
        bunifuImageButton1.BackColor = SystemColors.Control;
    }

    private void bunifuImageButton1_MouseUp(object sender, EventArgs e)
    {
        bunifuImageButton1.BackColor = SystemColors.HotTrack;
    }

    private void bunifuImageButton1_Click(object sender, EventArgs e)
    {
        this.Close();
    }

Answer 1

您可以跟踪鼠标是否已关闭，如果鼠标已关闭且离开按钮，则将颜色更改为悬停颜色。

但是有一个问题，因为如果鼠标停止，MouseLeave不会触发，所以你需要检查MouseMove事件上的鼠标位置，如下所示：

private bool isMouseDown;

private void bunifuImageButton1_MouseHover(object sender, EventArgs e)
{
    bunifuImageButton1.BackColor = SystemColors.Highlight;
}

private void bunifuImageButton1_MouseDown(object sender, MouseEventArgs e)
{
    bunifuImageButton1.BackColor = SystemColors.Control;
    isMouseDown = true;
}

private void bunifuImageButton1_MouseUp(object sender, MouseEventArgs e)
{
    bunifuImageButton1.BackColor = SystemColors.HotTrack;
    isMouseDown = false;
}

private void bunifuImageButton1_MouseMove(object sender, MouseEventArgs e)
{
    // If the mouse is down and the mouse is not over the button
    if (isMouseDown && !bunifuImageButton1.Bounds.Contains(e.Location))
    {
        bunifuImageButton1.BackColor = SystemColors.Highlight;
    }
}

您可以尝试使用平面样式按钮设置flatappearence颜色，并查看它是如何自动完成的。

回到＆＃39; MouseEnter＆＃39;鼠标之后的颜色＆＃39;叫做？
