在父容器中移动标签 [英] moving label in parent container

问题描述

您好

i有2个标签和一个图片框

2个标签将图片框作为父母

i想要将label1移动到label2位置

i使用以下代码

hi there
i have 2 labels and a picturebox
the 2 labels have the picturebox as parent
i want to move label1 to label2 location
i use the following code

private void Form1_Load(object sender, EventArgs e)
        {
            label2.Text = "stop here         ";
            make_item_transparent(label1, pictureBox1);
            make_item_transparent(label2, pictureBox1);
            
        }
        private void marquee_label(Label l)
        {
            if (l.Left > label2.Location.Y)
                l.Left = 0;
            else
                l.Left = l.Left + 1;
        }

        private void make_item_transparent(Label label, PictureBox bar)
        {
            var pos = this.PointToScreen(label.Location);
            pos = bar.PointToClient(pos);
            label.Parent = bar;
            label.Location = pos;
            label.BackColor = Color.Transparent;
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            marquee_label(label1);
        }

推荐答案

marquee_label的逻辑搞砸了。



您正在比较label1。左（基本上是X坐标）到label2.Location.Y（基本上是Y坐标或label2.Top）。因此，如果左侧位置大于label2.Top它会被重新抨击为0.



我相信如果你想要你想对label2.Left进行比较它们重叠，或者label2.Left - label1.Width，如果你想让它们相互对立。

The logic of marquee_label is messed up.

You're comparing label1.Left (basically the X-coordinate) to label2.Location.Y (basically the Y-coordinate or label2.Top). Therefore, if that Left position is greater than label2.Top it gets slammed back to 0.

I believe you want to do that comparison against label2.Left if you want them to overlap, or label2.Left - label1.Width if you want them to be up against each other.
