<p>TreeList控件实现右键菜单功能,其实跟TocControl控件实现原理是一样的,TocControl也是利用一个ContextMenu控件,利用HitT方法,TreeList利用其ContextMenuStrip属性就可以。</p><p>TocControl实现右键功能:</p>
private void MenuList_MouseDown(object sender, MouseEventArgs e)
{
//绑定右键菜单
if (e.Button == MouseButtons.Right)
{
MenuList.ContextMenu = null;
TreeListHitInfo hInfo = MenuList.CalcHitInfo(new Point(e.X, e.Y));
TreeListNode node = hInfo.Node;
MenuList.FocusedNode = node;
if (node != null)
{
MenuList.ContextMenuStrip = contextMenu;
}
}
}
TreeList实现右键功能:
private void axTOCControl_OnMouseDown_1(object sender, ITOCControlEvents_OnMouseDownEvent e)
{
if (e.button == 2)
{
esriTOCControlItem item = esriTOCControlItem.esriTOCControlItemNone;
IBasicMap m_BasicMap = null;
ILayer m_Layer = null;
object other = null;
object index = null;
axTOCControl.HitTest(e.x, e.y, ref item, ref m_BasicMap, ref m_Layer, ref other, ref index);
g_Layer = m_Layer;
if (item == esriTOCControlItem.esriTOCControlItemLayer)
{
cMStoc.Show(axTOCControl, new System.Drawing.Point(e.x, e.y));
}
}
}
