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.

Version 1.1
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.

tools.Translate(MaxLabel1, "title")
tools.Translate(MaxLabel2, "desc")

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

I can only guess that one of the properties isn't set.

 

[Jerryk]

Download new version 1.3, refresh library, open designer, set properties ad save.

Tip for custom views developers: when you add a new property, get the new value with Props.GetDefault. This way it will work with the default value without the need to set the updated properties with the designers.

Fixed in version 1.31
