总结实习经历，为以后面试准备

在2013年6月至2013年12月底，我在上海冠信电子系统有限公司（上海图元软件公司）实习，期间有一定收获，现在记录下来，以备将来面试之用。

1，流程图 

 

左右滑动track和view会触发2个事件，栅格缩放会触发一个事件，扫视和缩放也会触发一个事件。

 private void tsiZoomTrack_ValueChanged(object sender, EventArgs e)
        {
            int ratio100 = TrackValueConvertToRatio(this.tsiZoomTrack.Value);
            this.tsiZoomRatio.Text = string.Format("{0,3}%", ratio100);
            InitTsiZoomRatio();
            Get_CurrentZoomRatio(ratio100);
            if (this.overviewControl1.Diagram != null)
                this.overviewControl1.Diagram.View.Magnification = (float)ratio100;
        }

        private void tsiZoomView_Click(object sender, EventArgs e)
        {
            if (!this.overViewControlPanel.Visible)
            {
             
                overViewControlPanel.Location = new Point(this.diagram1.Width - overViewControlPanel.Width, this.diagram1.Height - overViewControlPanel.Height);
                overViewControlPanel.Show();
            }
            else
            {
                overViewControlPanel.Hide();
            }
        }

        private void overviewControl1_ViewPortBoundsChanged(ViewPortBoundsChangedEventArgs evtArgs)
        {
            int newValue = RatioConvertToTrackValue((int)this.overviewControl1.Diagram.View.Magnification);
            if (newValue != this.tsiZoomTrack.Value)
            {
                this.tsiZoomTrack.Value = newValue;
            }
        }

        private void diagram1_SizeChanged(object sender, EventArgs e)
        {
            overViewControlPanel.Location = new Point(this.diagram1.Width - overViewControlPanel.Width, this.diagram1.Height - overViewControlPanel.Height);
        }
