WPF从进度条获取矩形控件边界

Question

这一定是一个非常菜鸟的问题，所以请不要太苛刻地评判我！在 Windows 表单应用程序中，像这样的东西很容易获得进度条的界限：

progressBar1.Bounds.X(or)Y

如何在 WPF 中获得相同的内容？我在互联网上找不到任何关于此的内容。这是 windows 表单应用程序的进度条 OnClick 方法：

private void progressBar1_MouseClick(object sender, MouseEventArgs e)
{
    float absoluteMouse = (PointToClient(MousePosition).X - progressBar1.Bounds.X);
    float calcFactor = progressBar1.Width / (float)100;
    float relativeMouse = absoluteMouse / calcFactor;
    double maxlength = BASS_ChannelBytes2Seconds(BassHandle, (ulong)PlayBackLength);
    double percents = (maxlength * relativeMouse) / 100;
    UInt64 pos = BASS_ChannelSeconds2Bytes(BassHandle, percents);
    BASS_ChannelSetPosition(BassHandle, pos, 0);
    progressBar1.Value = Convert.ToInt32(relativeMouse);
    int current = BASS_ChannelGetPosition(BassHandle, 0);
    TimeLabel.Text = FormatTime(BASS_ChannelBytes2Seconds(BassHandle, (uint)current)) + "/" + FormatTime(BASS_ChannelBytes2Seconds(BassHandle, (uint)PlayBackLength));
}

这是我对 WPF 版本的尝试

private void progressBar1_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{

    double absoluteMouse = (PointFromScreen(GetMousePosition()).X - progressBar1.?);
    double calcFactor = progressBar1.Width / (float)100;
    double relativeMouse = absoluteMouse / calcFactor;
    double maxlength = Imports.BASS_ChannelBytes2Seconds(GlobalVariables.BassHandle, (ulong)GlobalVariables.PlayBackLength);
    double percents = (maxlength * relativeMouse) / 100;
    UInt64 pos = Imports.BASS_ChannelSeconds2Bytes(GlobalVariables.BassHandle, percents);
    Imports.BASS_ChannelSetPosition(GlobalVariables.BassHandle, pos, 0);
    progressBar1.Value = Convert.ToInt32(relativeMouse);
    int current = Imports.BASS_ChannelGetPosition(GlobalVariables.BassHandle, 0);
    TimeLabel.Text = FormatTime(Imports.BASS_ChannelBytes2Seconds(GlobalVariables.BassHandle, (uint)current)) + "/" + FormatTime(Imports.BASS_ChannelBytes2Seconds(GlobalVariables.BassHandle, (uint)GlobalVariables.PlayBackLength));
}

Answer 1

您可以使用 progressBar1.Margin.Left - 代表 X，progressBar1.Margin.Top - 代表 Y。但是相对于放置ProgressBar的Container会有价值。
