GetTextExtent with TX Text Control .NET for Windows Forms
The Lines collection in TX Text Control .NET for Windows Forms replaces the ActiveX GetTextExtent property for measuring document dimensions. TextBounds.Bottom on the last line returns total text height, while iterating all lines and comparing TextBounds.Right finds maximum width.
TX Text Control ActiveX contains a property which returns the extension of the complete text in twips. This method is not directly supported in the .NET version of TX Text Control. The Lines collection has been implemented to replace this method and includes lots of additional functionality.
The TextBounds property of the Line class gets the bounding rectangle of the text belonging to the line. We need the vertical distance between the upper left corner and the baseline of the last line to get the height of the complete text. Additionally, we need the longest line of the current document. This is done by checking the longest line in a loop.
Dim TextHeight As Long
Dim TextWidth As Long
TextHeight = TextControl1.Lines.Item(TextControl1.Lines.Count).TextBounds.Bottom
For Each line As TXTextControl.Line In TextControl1.Lines
Dim lineWidth As Long = TextControl1.Lines.Item(line.Number).TextBounds.Right
If TextWidth < lineWidth Then
TextWidth = lineWidth
End If
Next
Debug.WriteLine(TextHeight)
Debug.WriteLine(TextWidth)Related Posts
