Assembly: Microsoft.Ink (in microsoft.ink.dll)

Syntax

'Declaration
Public Event PanelChanged As PenInputPanelChangedEventHandler
'Usage
Dim instance As PenInputPanel
Dim handler As PenInputPanelChangedEventHandler

AddHandler instance.PanelChanged, handler

public event PenInputPanelChangedEventHandler PanelChanged

public:
event PenInputPanelChangedEventHandler^ PanelChanged {
    void add (PenInputPanelChangedEventHandler^ value);
    void remove (PenInputPanelChangedEventHandler^ value);
}

/** @event */
public void add_PanelChanged (PenInputPanelChangedEventHandler value)

/** @event */
public void remove_PanelChanged (PenInputPanelChangedEventHandler value)

In JScript, you can handle the events defined by a class, but you cannot define your own.

Not applicable.

Remarks

The event handler receives an argument of type PenInputPanelChangedEventArgs, containing data about this event.

When creating a PenInputPanel object, the Handwriting panel is the default panel type. If the panel is changed by setting the CurrentPanel property before pen input panel becomes active for the first time, a PanelChanged event occurs.

The PanelChanged event is not raised when the user changes between a PanelType panel used for multicharacter input, such as words, and a PanelType panel used for single character input.

Security Note:
If using under partial trust, this event requires SecurityPermissionFlag.AllFlags permission, in addition to the permissions required by PenInputPanel. See Security and Trust for more information.

Example

This C# example creates a PenInputPanel object, thePenInputPanel, and attaches it to an InkEdit control, theInkEdit. It then adds a PanelChanged event handler to thePenInputPanel. The PanelChanged handler sets the text of the attached InkEdit control to a sentence containing the new panel type.

[C#]

//...

// Delcare the PenInputPanel object
PenInputPanel thePenInputPanel;

public Form1()
{
    // Required for Windows Form Designer support
    InitializeComponent();

    // Create and attach the new PenInputPanel to an InkEdit control.
    thePenInputPanel = new PenInputPanel(theInkEdit);

    // Add a PanelChanged event handler
    thePenInputPanel.PanelChanged +=
        new PenInputPanelChangedEventHandler(PanelChanged_Event);
}

//...

public void PanelChanged_Event(object sender,
 PenInputPanelChangedEventArgs e)
{
    // Make sure the object that generated
    // the event is a PenInputPanel object
    if (sender is PenInputPanel)
    {
        PenInputPanel theSenderPanel = (PenInputPanel)sender;

        theSenderPanel.AttachedEditControl.Text = "The panel has changed to ";
        theSenderPanel.AttachedEditControl.Text += e.NewPanelType.ToString();
    }
}

This Microsoft® Visual Basic® .NET example creates a PenInputPanel object, thePenInputPanel, and attaches it to an InkEdit control, theInkEdit. It then adds a PanelChanged event handler to thePenInputPanel. The PanelChanged handler sets the text of the attached InkEdit control to a sentence containing the new panel type.

[Visual Basic]

Public Sub New()
    MyBase.New()

    'This call is required by the Windows Form Designer.
    InitializeComponent()

    If TypeOf sender Is PenInputPanel Then
