Re: DocumentView confusion

[Fabien Bodard <gambas.fr@xxxxxxxxx>]

'' Return the index of the first visible page.
Property Read FirstVisiblePage, FirstVisibleDocument As Integer

'' Return the index of the last visible page.
Property Read LastVisiblePage, LastVisibleDocument As Integer

FirstVisibleDocument and LastVisibleDocument are aliases
for FirstVisiblePage and  LastVisiblePage

These parameters are just the value of the partially drawn pages. They are
in fact used by the event manager to call pictures that need to be drawn.

The component remembers the content unless the zoom is used. in this case
the drawing need to be refreshed.


Private $hPdf As PdfDocument

Public Sub Button1_Click()

  If Not Dialog.OpenFile() Then

    $hPdf = New PdfDocument(Dialog.Path)
    DocumentView1.Count = $hPdf.Count
  Endif

End

Public Sub DocumentView1_Layout(Page As Integer)

  Last.Layout.Width = $hPdf[Page].W
  Last.Layout.Height = $hPdf[Page].H

End

Public Sub DocumentView1_Draw(Page As Integer, Width As Integer, Height As
Integer)

  Paint.DrawImage($hPdf[Page].Render(0, 0, Width, Height), 0, 0)

End
