准备工作
该控件将继承基类控件UCControlBase,如果你还对UCControlBase不了解,请移步 (一)c#Winform自定义控件-基类控件 查看
开始
这个控件比较简单,没有多少东西,看下关键代码吧
private int _value = ; public int Value
{
get { return this._value; }
set
{
if (value < )
return;
this._value = value;
SetValue();
}
} private int maxValue = ; public int MaxValue
{
get { return maxValue; }
set
{
if (value <= )
return;
maxValue = value;
SetValue();
}
} private void SetValue()
{
double dbl = (double)_value / (double)maxValue;
this.panel1.Width = (int)(this.Width * dbl);
} public ProcessExt()
{
InitializeComponent();
} private void ProcessExt_SizeChanged(object sender, EventArgs e)
{
SetValue();
} public void Step()
{
Value++;
}
然后看下完成代码吧
