Gets a Rectangle object that represents the area that is not obscured by the soft input panel (SIP).

Namespace: Microsoft.WindowsCE.Forms
Assembly: Microsoft.WindowsCE.Forms (in Microsoft.WindowsCE.Forms.dll)

Syntax

'Declaration
Public ReadOnly Property VisibleDesktop As Rectangle
    Get
'Usage
Dim instance As InputPanel
Dim value As Rectangle

value = instance.VisibleDesktop

public Rectangle VisibleDesktop { get; }

public:
property Rectangle VisibleDesktop {
    Rectangle get ();
}

member VisibleDesktop : Rectangle

Property Value

Type: System.Drawing.Rectangle
An object that represents the area that is not occupied by the SIP.

Remarks

The VisibleDesktop property provides a Rectangle with the dimensions of the area of the form that is not occupied by the SIP. When the SIP is enabled, you can reposition or resize controls to be within this area. If you are developing for a Windows Embedded CE-based device other than a Pocket PC, the VisibleDesktop property returns the largest rectangle in the area of the form that is not occupied by the SIP. If the SIP is off the form, VisibleDesktop returns the dimensions of the client area of the form.

Examples

The following example uses the EnabledChanged event to decrease the height of a tab control when the SIP is enabled. It returns the tab control to its original height when the SIP is disabled. The example examines the VisibleDesktop property when the SIP is enabled and disabled so that the tab control height can be adjusted to accommodate the SIP. This example is part of a larger example provided for the InputPanel component.

Private Sub InputPanel1_EnabledChanged(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles InputPanel1.EnabledChanged
 If InputPanel1.Enabled = False Then

  ' The SIP is disabled, so set the height of the tab control
  ' to its original height with a variable (TabOriginalHeight),
  ' which is determined during initialization of the form.
  VisibleRect = InputPanel1.VisibleDesktop
  TabControl1.Height = TabOriginalHeight
 Else
  ' The SIP is enabled, so the height of the tab control
  ' is set to the height of the visible desktop area.
  VisibleRect = InputPanel1.VisibleDesktop
  TabControl1.Height = VisibleRect.Height
 End If

 ' The Bounds property always returns a width of 240 and a height of 80
 ' pixels for Pocket PCs, regardless of whether or not the SIP is enabled.
 BoundsRect = InputPanel1.Bounds

 ' Show the VisibleDesktop and Bounds values
 ' on the second tab for demonstration purposes.
       VisibleInfo.Text = String.Format("VisibleDesktop: X = {0}, " _
       & "Y = {1}, Width = {2}, Height = {3}", _
       VisibleRect.X, VisibleRect.Y, _
       VisibleRect.Width, VisibleRect.Height)
       BoundsInfo.Text = String.Format("Bounds: X = {0}, Y = {1}," _
          & "Width = {2}, Height = {3}", BoundsRect.X, BoundsRect.Y, _
          BoundsRect.Width, BoundsRect.Height)
End Sub

private void inputPanel1_EnabledChanged(object sender, EventArgs e)
{
    if (inputPanel1.Enabled == false)
    {
        // The SIP is disabled, so set the height of the tab control
        // to its original height with a variable (TabOriginalHeight),
        // which is determined during initialization of the form.
        VisibleRect = inputPanel1.VisibleDesktop;
        tabControl1.Height = TabOriginalHeight;
    }
    else
    {
        // The SIP is enabled, so the height of the tab control
        // is set to the height of the visible desktop area.
        VisibleRect = inputPanel1.VisibleDesktop;
        tabControl1.Height = VisibleRect.Height;
    }

    // The Bounds property always returns a width of 240 and a height of 80
    // pixels for Pocket PCs, regardless of whether or not the SIP is enabled.
    BoundsRect = inputPanel1.Bounds;

    // Show the VisibleDestkop and Bounds values
    // on the second tab for demonstration purposes.
    VisibleInfo.Text = String.Format("VisibleDesktop: X = {0}, " +
        "Y = {1}, Width = {2}, Height = {3}", VisibleRect.X,
        VisibleRect.Y, VisibleRect.Width, VisibleRect.Height);
    BoundsInfo.Text = String.Format("Bounds: X = {0}, Y = {1}, " +
        "Width = {2}, Height = {3}", BoundsRect.X, BoundsRect.Y,
        BoundsRect.Width, BoundsRect.Height);
}
