获取滑块的X，Y坐标/位置

Question

I need to get the [X,Y] positions of a slider. I already tried the function "PointFromScreen" but I didn't get any result.

Anyone?

Thanks

    private void SliderPosition(object sender)
    {
        Slider slider = (Slider)sender;
        int x = (int)slider.Value;
        Point x1 = Point.Parse(x);
        Point slider_point = slider.PointFromScreen(x1);
    }

UPDATE and more clear doubt:

I have a video going through, and a slide that is dependent of the number of frames. Video format is 640x480, slider is defined in terms of frames!

I need to know, when the right button is pushed in the video image, the position[X,Y] of the slider so that I can draw a line in a Canvas that is beneath the video.

I think it's clear now. Going through the library, the only parameter I can find is the slider.value but that doesn't make my case.

Source code of my try:

     private void Slider_position(object sender, System.Windows.Controls.Slider e,    System.Windows.Input.MouseEventArgs e1)
    {
        if (e1.RightButton == MouseButtonState.Pressed)
        {
            Line line = new Line();
            line.X1 = e. //something, i would get here the coordinates X,Y of slider here
            // calculation from slider position to canvas position
            // draw a line of the height of the canvas here after

        }
    }

尝试使用MouseClick（），因为这将为您提供AutoIt窗口信息中的鼠标位置。
