B4A Library MaxLabel

I have modified a custom view AutoTextSizeLabel where the font size is maximized either in height or width.
Now it takes into account both borders and padingns. It is packaged in the b4xlib library.

MaxLabel
Author: Jerryk
Version: 1.30

Methods:
  • Text As String
Sets or gets text of Label.
  • Base As Label
All Label methods are available through Base (e.g. Maxlabel.Base.TextColor, Maxlabel.Base.Top, etc.)

Properties:
  • PreferHeight As Boolean
Fill height is preferred. In case of long text it will be displayed on multiple lines.
  • MaxSize As Int
Set maximixed size of font. 0 - no limit
  • SingleLine As Boolean
When using the SingleLine property, use "overwritten". This is because it needs to be read for calculations, but in the original it is writeonly.

added Tag property

Example of using the Tag property. For example, you can translate text into another language and adjust the size to the new content directly using the Designer script.
script: 
tools.Translate(MaxLabel1, "title")
tools.Translate(MaxLabel2, "desc")
tools: 
Private Sub Translate(DesignerArgs As DesignerArgs)
    Sleep(10)  'Do not delete!
    If DesignerArgs.FirstRun Then
        Dim text As String = DesignerArgs.Arguments.Get(1)
        Dim v As B4XView = DesignerArgs.GetViewFromArgs(0)
        If v.Tag Is MaxLabel Then
            Dim ml As MaxLabel
            ml = v.Tag
            ml.Text = Loc(text) 'localization function
        Else
            v.Text = Loc(text) 'localization function
        End If
    End If
End Sub
