进度条点击=>更改当前曲目播放位置

发布于 2024-09-29 05:12:27 字数 125 浏览 3 评论 0原文

我正在winforms 中制作一个音乐播放器。我有一个进度条，当我单击进度条上的某个位置时，我想获取该位置的整数（从 1 到 100，即当我想要到达歌曲中的某个点时）。我怎样才能做到这一点？

问候，亚历山德鲁·巴德斯库

使用 TrackBar 控件，以及这可能是一篇高级文章，希望对您有所帮助。

祝你好运。

试试这个：

'Using The Click or MouseDown or any Mouse Event

Dim Value As Integer= Me.PointToClient(MousePosition).X-Progressbar.Bounds.X

Progressbar.value= Value

Try this:

'Using The Click or MouseDown or any Mouse Event

Dim Value As Integer= Me.PointToClient(MousePosition).X-Progressbar.Bounds.X

Progressbar.value= Value

您可以使用必须放置在进度条上的控件——例如一个小子弹。
现在，如果您使用代码，

progressbar1.value=control.location.x/y

请将控件的名称放置在控件 x/y 决定坐标的位置。

请注意，您必须移动进度条上的控件以进行简化使用图片框并使用 keydown 事件将其并排移动

you can use a control that have to be placed on the progress bar --like a small bullet .
now if you use the code

progressbar1.value=control.location.x/y

place the name of the control at the position of control x/y decides the coordinates.

make a note that you have to move the control on the progress bar for simplifications use a picture box and use the keydown event to move it side by side

该值会显示一个与进度条上单击位置相关的值。这里的取值范围是从0到100%计算的。它还与进度条的宽度有关，因此范围将保持固定为百分比逻辑。

private void progressBar1_Click(object sender, EventArgs e)
        {
            // Get mouse position(x) minus the width of the progressbar (so beginning of the progressbar is mousepos = 0 //
            float absoluteMouse = (PointToClient(MousePosition).X - progressBar1.Bounds.X);
            // Calculate the factor for converting the position (progbarWidth/100) //
            float calcFactor = progressBar1.Width / (float)progressBar1.Maximum;
            // In the end convert the absolute mouse value to a relative mouse value by dividing the absolute mouse by the calcfactor //
            float relativeMouse = absoluteMouse / calcFactor;

            // Set the calculated relative value to the progressbar //
            progressBar1.Value = Convert.ToInt32(relativeMouse);
        }

我知道这个问题很久以前就被问过，但它没有正确的解决方案。现在就是这样。

This one brings up a value in relation to the position where the click was done on the progressbar. The value range here is calculated from 0 to 100%. Its also in relation to the width of the progressbar so the range will stay fixed to percentage logic.

private void progressBar1_Click(object sender, EventArgs e)
        {
            // Get mouse position(x) minus the width of the progressbar (so beginning of the progressbar is mousepos = 0 //
            float absoluteMouse = (PointToClient(MousePosition).X - progressBar1.Bounds.X);
            // Calculate the factor for converting the position (progbarWidth/100) //
            float calcFactor = progressBar1.Width / (float)progressBar1.Maximum;
            // In the end convert the absolute mouse value to a relative mouse value by dividing the absolute mouse by the calcfactor //
            float relativeMouse = absoluteMouse / calcFactor;

            // Set the calculated relative value to the progressbar //
            progressBar1.Value = Convert.ToInt32(relativeMouse);
        }

I know this question was asked a long time ago, but it was out of the right solution. Here it is now.
