Examples

[C#]

This C# example shows how you could have a menu item called menuItemEdit which contains two submenus called menuItemCopy and menuItemPaste for copying and pasting selected strokes. Two methods are shown: menuItemCopy_Click (the event handler that is called when menuItemCopy is clicked) and menuItemEdit_Popup (the event handler that is called when the submenus of menuItemEdit are shown). In menuItemCopy, the selected ink from an InkOverlay named theInkOverlay is copied into the clipboard in Ink Serialized Format. In menuItemEdit_Popup, the menuItemCopy control is only enabled if one or more strokes are selected, and the menuItemPaste control is only enabled if ink has been copied to the clipboard in ISF. You can check this by using the InkSerializedFormat field.

private void menuItemCopy_Click(object sender, System.EventArgs e)
{
    // Check if anything is selected
    if (theInkOverlay.Selection.Count > 0)
    {
        // Copy the ink as ISF
        theInkOverlay.Ink.ClipboardCopy(theInkOverlay.Selection,
            InkClipboardFormats.InkSerializedFormat, InkClipboardModes.Copy);
    }
}

private void menuItemEdit_Popup(object sender, System.EventArgs e)
{
    // Only enable Copy if something is selected
    menuItemCopy.Enabled = (theInkOverlay.Selection.Count > 0);

    // Only enable Paste if ink serialialized format is in the clipboard
    IDataObject clipboardObject = Clipboard.GetDataObject();
    menuItemPaste.Enabled =
        clipboardObject.GetDataPresent(Ink.InkSerializedFormat);
}
