默认工具提示对我来说效果不佳,所以我在按下某个键时使用Label Control及其“Visible”属性作为错误Popup进行了自定义工具提示。所以现在我试图动态设置标签的位置,在我的情况下设置为textBox的位置,但它总是显示在表单的左上角。
以下是方法:
void ShowCustomToolTip(string text, Control targetControl, int duration = 1000, int x = 0, int y = 0)
{
customToolTip.Text = text;
customToolTip.Visible = true;
// the crucial line that needs to be changed, I guess
customToolTip.Location = new Point(targetControl.Location.X + x, targetControl.Location.Y + y);
Set.Timer(duration);
customToolTip.Hide();
}
我怎样才能做到这一点?谢谢!

问题是Control.Location
给出了你在当前容器中的位置。你只需要获得控件的绝对位置,就像这样:
void ShowCustomToolTip(string text, Control targetControl, int duration = 1000, int x = 0, int y = 0)
{
customToolTip.Text = text;
customToolTip.Visible = true;
Point absoluteLocation = targetControl.FindForm().PointToClient(
targetcontrol.Parent.PointToScreen(control.Location));
// the crucial line that needs to be changed, I guess
customToolTip.Location = new Point(absoluteLocation.X + x, absoluteLocation.Y + y);
Set.Timer(duration);
customToolTip.Hide();
}
