Set Context Menus

Viewer Context Menu

Each ImageXView object can have one associated context menu, which provides options to the user within the control window. To define a context menu for the viewer, call ImageXView.ContextMenu. The ContextMenu property inherits from System.Windows.Forms.Control. By default, this property is set to an instance of the ImagXpressDefaultContextMenu class. This class provides a default set of menu items that operate on the ImageXView.

The following code example demonstrates how to add a new item to the context menu:

C# Example	Copy Code
MenuItem menuBlack = new MenuItem(); menuBlack.Text = "Preserve Black"; menuBlack.Name = "Black"; menuBlack.Checked = false; imageXView1.ContextMenu.MenuItems.Add(6, menuBlack);

The following code example demonstrates how to remove a menu item from the ImagXpress menu:

C# Example	Copy Code
imageXView1.ContextMenu.MenuItems[1].Visible = false;

The following code example demonstrates how to connect an event handler to a menu item:

C# Example	Copy Code
for (int i = 0; i < imageXView1.ContextMenu.MenuItems.Count; i++) { imageXView1.ContextMenu.MenuItems[i].Click += new EventHandler(ContextMenuClickEventHandler); ///must remove event handler during cleanup code } //event handler private void ContextMenuClickEventHandler(object sender, EventArgs e) { … }

C# Example

Copy Code

for (int i = 0; i < imageXView1.ContextMenu.MenuItems.Count; i++)
{
                 
 imageXView1.ContextMenu.MenuItems[i].Click += new   EventHandler(ContextMenuClickEventHandler);
             ///must remove event handler during cleanup code
}
//event handler 
private void ContextMenuClickEventHandler(object sender, EventArgs e)
{
           …
}

Toolbar Context Menu

Each ImageXView object also has one associated toolbar (Toolbar). The toolbar has an associated context menu, which provides application end-users with options for accessing each of the tools. The toolbar context menu is defined using the methods within the ImageXView.Toolbar.ContextMenu.
