Font size

[omoba]

Hi,

I created a seekbar to increase and decrease font size.

When I increase the font size and the text gets big enough/too big, the text goes outside the view-able range of the label.

Is there a way to prevent this from happening?

Thanks

You should limit the size set by the seekbar, say to FontLimit:

sub sb_ValueChanged (Value As Int, UserChanged As Boolean)
fontsize = min(Value, FontLimit)

Another way is to use canvas methods,

MeasureStringWidth (Text As String, Typeface As android.graphics.Typeface, TextSize As Float) As Float

or to measure the Height with MeasureStringHeight
