C# Winform
在MDI窗体定义
public interface ICipherInputForm
{
ToolStrip CipherToolStrip
{
get;
}
}
在MdiChildActivate事件中加入
private void MainFrame_MdiChildActivate(object sender, EventArgs e)
{
//CTools为MDI窗体工具栏
ToolStripManager.RevertMerge(CTools);
if (this.ActiveMdiChild != null)
{
if ((ActiveMdiChild as ICipherInputForm).CipherToolStrip != null)
{
ToolStripManager.Merge((ActiveMdiChild as ICipherInputForm).CipherToolStrip,CTools);
}
}
//若子窗体无工具栏时,隐藏该工具栏
if (CTools.Items.Count > 0)
CTools.Visible = true;
else
CTools.Visible = false;
}
在子窗体
public partial class FrmPowerTeam : Form,MainFrame.ICipherInputForm
{
//Tools为你子窗体的工具栏.注意将其Visible = false;
public ToolStrip CipherToolStrip
{
get
{
return Tools;
}
}
}
