實(shí)現(xiàn)方式主要是利用panel控件為主題，對(duì)于每個(gè)控件的大小位置和字體這幾個(gè)屬性進(jìn)行記錄，然后根據(jù)窗體改變的大小同時(shí)放縮。
簡(jiǎn)要步驟如下：
1、創(chuàng)建C#窗體程序項(xiàng)目。
2、Panel放置到窗體。
3、設(shè)置屬性dock為fill。
4、注意MinnumSize不能設(shè)置為0， 改成大于0都行。
復(fù)制代碼 代碼如下:
public partial class FrmDemo : Form
{
double dFrmWidth;
double dFrmHeight;
double dZoomHorizon;
double dZoomVerticality;
Dictionarystring, string> dicControlsAttribute = new Dictionarystring, string>();
protected void GetAllInitiateContrlInfo(Control CrlContainer)
{
if (CrlContainer.Parent == this)
{
dFrmWidth = Convert.ToDouble(CrlContainer.Width);
dFrmHeight = Convert.ToDouble(CrlContainer.Height);
}
foreach (Control item in CrlContainer.Controls)
{
if (item.Name.Trim() != "")
dicControlsAttribute.Add(item.Name, (item.Left + item.Width / 2) + "," + (item.Top + item.Height / 2)
+ "," + item.Width + "," + item.Height + "," + item.Font.Size);
if ((item as UserControl) == null item.Controls.Count > 0)
GetAllInitiateContrlInfo(item);
}
}
private void ChangeControlsInitiate(Control CrlContainer)
{
dZoomHorizon = (Convert.ToDouble(CrlContainer.Width) / dFrmWidth);
dZoomVerticality = (Convert.ToDouble(CrlContainer.Height) / dFrmHeight);
}
private void ChangeCurrentControlAttr(Control CrlContainer)
{
double[] dPosition = new double[5];
foreach (Control item in CrlContainer.Controls)
{
if (item.Name.Trim() != "")
{
if ((item as UserControl) == null item.Controls.Count > 0)
ChangeCurrentControlAttr(item);
string[] strs = dicControlsAttribute[item.Name].Split(',');
for (int j = 0; j 5; j++)
{
dPosition[j] = Convert.ToDouble(strs[j]);
}
double itemWidth = dPosition[2] * dZoomHorizon;
double itemHeight = dPosition[3] * dZoomVerticality;
item.Left = Convert.ToInt32(dPosition[0] * dZoomHorizon - itemWidth / 2);
item.Top = Convert.ToInt32(dPosition[1] * dZoomVerticality - itemHeight / 2);
item.Width = Convert.ToInt32(itemWidth);
item.Height = Convert.ToInt32(itemHeight);
//item.Font = new Font(item.Font.Name, float.Parse
//((dPosition[4] * Math.Min(dZoomHorizon, dZoomVerticality)).ToString()));
//字體也可以實(shí)現(xiàn)同比放縮。
}
}
}
protected override void OnSizeChanged(EventArgs e)
{
base.OnSizeChanged(e);
if (dicControlsAttribute.Count > 0)
{
ChangeControlsInitiate(this.Controls[0]);
ChangeCurrentControlAttr(this.Controls[0]);
}
}
public FrmDemo()
{
InitializeComponent();
GetAllInitiateContrlInfo(this.Controls[0]);//構(gòu)造函數(shù)里面調(diào)用即可。
}
}
