实现步骤:
1.在窗体中放一个容器(例如:Panel),并且将容器的Dock属性设置为Fill。窗体中其他控件都放在这个容器中。
2.创建一个窗体类,该类继承于原始窗体类,并在新建的这个窗体类中添加如下代码,以后创建的窗体都继承于新建的这个窗体类:
#region 控件缩放double formWidth; // 窗体原始宽度
double formHeight; // 窗体原始高度
double scaleX; // 水平缩放比例
double scaleY; // 垂直缩放比例
Dictionary< string , string > controlInfo = new Dictionary< string , string >(); // 控件中心Left,Top,控件Width,控件Height,控件字体Size
/// <summary>
/// 获取所有原始数据
/// </summary>
protected void GetAllInitInfo(Control CrlContainer)
{
if (CrlContainer.Parent == this )
{
formWidth = Convert.ToDouble(CrlContainer.Width);
formHeight = Convert.ToDouble(CrlContainer.Height);
}
foreach (Control item in CrlContainer.Controls)
{
if (item.Name.Trim() != "" )
controlInfo.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 )
GetAllInitInfo(item);
}
}
private void ControlsChangeInit(Control CrlContainer)
{
scaleX = (Convert.ToDouble(CrlContainer.Width) / formWidth);
scaleY = (Convert.ToDouble(CrlContainer.Height) / formHeight);
}
private void ControlsChange(Control CrlContainer)
{
double [] pos = new double [ 5 ]; // pos数组保存当前控件中心Left,Top,控件Width,控件Height,控件字体Size
foreach (Control item in CrlContainer.Controls)
{
if (item.Name.Trim() != "" )
{
if ( (item as UserControl) == null && item.Controls.Count > 0 )
ControlsChange(item);
string [] strs = controlInfo[item.Name].Split( ' , ' );
for ( int j = 0 ; j < 5 ; j++)
{
pos[j] = Convert.ToDouble(strs[j]);
}
double itemWidth = pos[ 2 ] * scaleX;
double itemHeight = pos[ 3 ] * scaleY;
item.Left = Convert.ToInt32(pos[ 0 ] * scaleX - itemWidth / 2 );
item.Top = Convert.ToInt32(pos[ 1 ] * scaleY - itemHeight / 2 );
item.Width = Convert.ToInt32(itemWidth);
item.Height = Convert.ToInt32(itemHeight);
item.Font = new Font(item.Font.Name, float .Parse((pos[ 4 ] * Math.Min(scaleX, scaleY)).ToString()));
}
}
}
}
}
private void ControlsChangeInit(Control CrlContainer)
{
scaleX = (Convert.ToDouble(CrlContainer.Width) / formWidth);
scaleY = (Convert.ToDouble(CrlContainer.Height) / formHeight);
}
private void ControlsChange(Control CrlContainer)
{
double [] pos = new double [ 5 ]; // pos数组保存当前控件中心Left,Top,控件Width,控件Height,控件字体Size
foreach (Control item in CrlContainer.Controls)
{
if (item.Name.Trim() != "" )
{
if ( (item as UserControl) == null && item.Controls.Count > 0 )
ControlsChange(item);
string [] strs = controlInfo[item.Name].Split( ' , ' );
for ( int j = 0 ; j < 5 ; j++)
{
pos[j] = Convert.ToDouble(strs[j]);
}
double itemWidth = pos[ 2 ] * scaleX;
double itemHeight = pos[ 3 ] * scaleY;
item.Left = Convert.ToInt32(pos[ 0 ] * scaleX - itemWidth / 2 );
item.Top = Convert.ToInt32(pos[ 1 ] * scaleY - itemHeight / 2 );
item.Width = Convert.ToInt32(itemWidth);
item.Height = Convert.ToInt32(itemHeight);
item.Font = new Font(item.Font.Name, float .Parse((pos[ 4 ] * Math.Min(scaleX, scaleY)).ToString()));
}
}
}
#endregion
3.在新建的窗体类中重写OnSizeChanged事件,并调用ControlsChangeInit和ControlsChange方法,代码如下:
protected
override
void
OnSizeChanged(EventArgs e)
{
base .OnSizeChanged(e);
if (controlInfo.Count > 0 )
{
ControlsChangeInit( this .Controls[ 0 ]);
ControlsChange( this .Controls[ 0 ]);
}
}
{
base .OnSizeChanged(e);
if (controlInfo.Count > 0 )
{
ControlsChangeInit( this .Controls[ 0 ]);
ControlsChange( this .Controls[ 0 ]);
}
}
4.在窗体的构造函数中调用GetAllInitInfo方法,代码如下:
GetAllInitInfo( this .Controls[ 0 ]);
