下面的代码示例演示如何将 BeginDrag 和 EndDrag 与 和 一ToolStripContainer起使用ToolStrip。
using System;
using System.Windows.Forms;
public class Form1 : Form
{
private ToolStripContainer toolStripContainer1;
private ToolStrip toolStrip1;
private RichTextBox richTextBox1;
public Form1()
{
DragToolStrip();
}
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.Run(new Form1());
}
private void DragToolStrip()
{
// Create a ToolStripContainer.
toolStripContainer1 = new System.Windows.Forms.ToolStripContainer();
toolStripContainer1.Dock = System.Windows.Forms.DockStyle.Fill;
Controls.Add(toolStripContainer1);
// Create a ToolStrip and add items to it.
toolStrip1 = new System.Windows.Forms.ToolStrip();
toolStrip1.Items.Add("One");
toolStrip1.Items.Add("Two");
toolStrip1.Items.Add("Three");
// Add the ToolStrip to the top panel of the ToolStripContainer.
toolStripContainer1.TopToolStripPanel.Controls.Add(toolStrip1);
// Create a RichTextBox and add it to the ContentPanel.
richTextBox1 = new System.Windows.Forms.RichTextBox();
richTextBox1.Location = new System.Drawing.Point(94, 61);
toolStripContainer1.ContentPanel.Controls.Add(richTextBox1);
// Attach event handlers for the BeginDrag and EndDrag events.
toolStrip1.BeginDrag += new System.EventHandler(toolStrip1_BeginDrag);
toolStrip1.EndDrag += new System.EventHandler(toolStrip1_EndDrag);
}
// Clear any text from the RichTextBox when a drag operation begins.
private void toolStrip1_BeginDrag(object sender, EventArgs e)
{
richTextBox1.Text = "";
}
// Notify the user when the drag operation ends.
private void toolStrip1_EndDrag(object sender, EventArgs e)
{
richTextBox1.Text="The drag operation is complete.";
}
}
