Definition

Visual Basic .NET Public ReadOnly Property Left As Integer
C# public int Left { get; }
Managed C++ public: __property int* get_Left();

Property Value

System.Int32. The horizontal, or x-axis, location of the left edge of the PenInputPanel object, in screen coordinates.

This property is read-only. This property has no default value.

Exceptions

ObjectDisposedException Leave Site:

Remarks

To explicitly override the automatic positioning behavior of the PenInputPanel object, use the Left and Top properties of the object to determine the current position of the pen input panel. If the pen input panel is located on a section of the screen that should be visible, use the MoveTo method to relocate the pen input panel.

You can also override the automatic positioning behavior of the PenInputPanel object by listening for the Left and Top properties of the PenInputPanelMovingEventArgs object during a PanelMoving event. If the pen input panel is located on a section of the screen that should be visible, use the MoveTo method to relocate the pen input panel.

Examples

[C#]

This C# example creates a PenInputPanel object, thePenInputPanel, and attaches it to an InkEdit control, theInkEdit. It then attaches a VisibleChanged event handler, VisibleChanged_Event. The event handler uses the Left property to add a sentence to the content of theInkEdit, stating where the left edge of the PenInputPanel object is located, in screen coordinates.

//...

// Declare 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 VisibleChanged event handler
    thePenInputPanel.VisibleChanged +=
        new PenInputPanelVisibleChangedEventHandler(VisibleChanged_Event);
}

//...

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

        // When the panel has become visible...
        if (e.NewVisibility)
        {
            // Display the left edge of the
            // panel in the attached edit control
            theSenderPanel.AttachedEditControl.Text +=
                    "The left edge of the panel is at ";
            theSenderPanel.AttachedEditControl.Text += theSenderPanel.Left.ToString();
            theSenderPanel.AttachedEditControl.Text += " pixels.\n";
        }
    }
}
