实现MDI窗体的工具栏合并功能的步骤
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; } } }
