ScrollTrackExtent Property (MdiTabGroupSettings)

Returns or sets the extent for the scroll track.
Syntax
'Declaration
 
Public Property ScrollTrackExtent As Integer
public int ScrollTrackExtent {get; set;}
Remarks

ScrollTrackExtent is the width of the scroll track used to navigate between the tab items. The scroll track is only displayed when the Thumb enum is included in the ScrollButtonTypes property. The ScrollButtons property is used to determine when the scroll buttons should be displayed. By default, they are only displayed when there isn't enough room to display all the tab items.

Example
The following example demonstrates how to set the various MdiTabGroupSetting properties that relate to StateButton style tabs.

Imports Infragistics.Win
Imports Infragistics.Win.UltraWinTabs
Imports Infragistics.Win.UltraWinTabbedMdi

Private Sub InitializeStateButtonTabGroup(ByVal tabGroup As MdiTabGroup)
    ' display the tabs as state buttons
    tabGroup.Settings.TabStyle = TabStyle.StateButtons

    ' display a separator bar between the state buttons
    tabGroup.Settings.ShowButtonSeparators = DefaultableBoolean.True

    ' leave 9 pixels of space between the state button tabs
    tabGroup.Settings.InterTabSpacing = New DefaultableInteger(9)

    ' use office xp style buttons for the close and scroll buttons
    tabGroup.Settings.ButtonStyle = UIElementButtonStyle.OfficeXPToolbarButton

    ' use the xp style chevron arrow for the scroll buttons
    tabGroup.Settings.ScrollArrowStyle = ScrollArrowStyle.WindowsXP

    ' only show the scroll buttons when needed
    tabGroup.Settings.ScrollButtons = DefaultableTabScrollButtons.Automatic

    ' show the next/previous and next page/ previous page buttons
    ' and scroll track/thumb when scroll buttons are displayed
    tabGroup.Settings.ScrollButtonTypes = ScrollButtonTypes.NextPagePreviousPage Or _
        ScrollButtonTypes.NextPrevious Or ScrollButtonTypes.Thumb

    ' when the scroll track is displayed, it should be no less than 40 pixels
    tabGroup.Settings.ScrollTrackExtent = 40
End Sub
