How to get the Location of Tab with respect to screen?

 

The TabControlAdded event should be handled to access the TabControlAdv. Then subscribe into the DrawItem event which handles the drawItemInfo and get the bounds of the tabs. This should be stored in a HashTable for further reference. Please refer the below code snippet which illustrates this:

C#

void tb_TabControlAdded(object sender, TabbedMDITabControlEventArgs args)

{

args.TabControl.DrawItem += new DrawTabEventHandler(mtp_DrawItem);

}

void mtp_DrawItem(object sender, DrawTabEventArgs drawItemInfo)

{

MDITabPanel mtp = sender as MDITabPanel;

// Drawing background,borders,interior as usual

drawItemInfo.DrawBackground();

drawItemInfo.DrawBorders();

drawItemInfo.DrawInterior();

/*If hashtable contains entry for particular window title just update position else add a new entry */

if (!ht.Contains(mtp.TabPages[drawItemInfo.Index].Text))

ht.Add(mtp.TabPages[drawItemInfo.Index].Text, mtp.PointToScreen(drawItemInfo.Bounds.Location));

else

ht[mtp.TabPages[drawItemInfo.Index].Text] = mtp.PointToScreen(drawItemInfo.Bounds.Location);

}

VB

Private Sub tb_TabControlAdded(ByVal sender As Object, ByVal args As TabbedMDITabControlEventArgs)

AddHandler args.TabControl.DrawItem, AddressOf DrawItem

End Sub

Private Sub DrawItem(ByVal sender As Object, ByVal drawItemInfo As DrawTabEventArgs)

Dim mtp As MDITabPanel = CType(sender, MDITabPanel)

' Drawing background,borders,interior as usual

drawItemInfo.DrawBackground()

drawItemInfo.DrawBorders()

drawItemInfo.DrawInterior()

'If hashtable contains entry for particular window title just update position else add a new entry

If Not ht.Contains(mtp.TabPages(drawItemInfo.Index).Text) Then

ht.Add(mtp.TabPages(drawItemInfo.Index).Text, mtp.PointToScreen(drawItemInfo.Bounds.Location))

Else

ht(mtp.TabPages(drawItemInfo.Index).Text) = mtp.PointToScreen(drawItemInfo.Bounds.Location)

End If

End Sub
