Hi all, i'm testing the wrap_content with the next code:


Dim lbl1 As Label
Dim lbl2 As Label
lbl1.Initialize("")
lbl2.Initialize("")

lbl1.Text = "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wsssssssssssssssssssssssssdrfhssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wsssssssssssssssssssssssssdrfhssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF & "wssssssssssssssssssssssssssssssssssssssssssssssssssssssssss" & CRLF
Dim cnv As Canvas
cnv.Initialize(Activity)

Dim he As Int
lbl1.TextSize = 12dip
lbl1.TextColor = Colors.Yellow
he = cnv.MeasureStringHeight(lbl1.Text,Typeface.DEFAULT,12dip)
'ToastMessageShow(he,True)
Activity.AddView(lbl1,50dip,50dip,200dip,-2)
Dim hei As Int
hei = hei + 50dip + lbl1.Height
lbl2.Text = "holaaa"
lbl2.TextColor = Colors.Red
lbl2.TextSize = 12dip
Dim r As Reflector
r.Target = lbl1
Dim a As Int
DoEvents
a = r.RunMethod("getHeight")
ToastMessageShow(a,True)
Activity.AddView(lbl2,50dip,(50dip+a),200dip,40Dip)



i'm seeing the height of the field and i get max 302, that is lower than the real height.
In other program (not for testing) i get max 112 of height, and the height of field should be much more, any idea?

What exactly is the problem ?
A multiline text is wraped to the next line if there is no more place in the current line.
So in this case the width is the view width.
If you mean texts lines separated by CRLF the you might split the text in lines and check the longest width.
