I use a LCDLabel and make the text "W". If I now resize the LCDLabel the text resizes at the same time. Is there a way I can do this with a Label?

This code shows the issue: -

Code (gambas)

  1. Label1 As Label
  2. LCDLabel1 As LCDLabel
  3.  
  4. Public Sub Form_Open()
  5.  
  6.   With Me
  7.     .Text = "Resize me"
  8.     .Arrangement = Arrange.Horizontal
  9.     .H = 150
  10.     .W = 150  
  11.     .Padding = 5
  12.   End With
  13.  
  14.   With Label1 = New Label(Me)
  15.     .Alignment = Align.Center
  16.     .Expand = True
  17.     .Font.Size = 12
  18.     .Text = "W"
  20.  
  21.   With LCDLabel1 = New LCDLabel(Me)
  22.     .Expand = True
  23.     .Text = "W"
  25.  
  27.

Not by default, it's all about Font size for labels.

must be some workarounds though

this works on your above example (and if using different text/words)…

Code (gambas)

  1. Public Sub Form_Resize()
  2.  
  3.   ' if label text height and width are less than the label size then increase Font.Size
  4.   If Label1.Font.Height < Label1.Height And If Label1.Font.TextWidth(Label1.Text) < Label1.W Then
  5.     Do
  6.       If Label1.Font.Height < Label1.Height And If Label1.Font.TextWidth(Label1.Text) < Label1.W Then
  7.         Inc Label1.Font.Size
  8.       Else
  9.         Break
  10.       Endif
  11.     Loop
  12.  
  13.   ' if label text height or width is more than the label size then decrease Font.Size
  14.   Else If Label1.Font.Height > Label1.Height Or If Label1.Font.TextWidth(Label1.Text) > Label1.W Then
  15.     Do
  16.       If Label1.Font.Height > Label1.Height Or If Label1.Font.TextWidth(Label1.Text) > Label1.W Then
  17.         If Label1.Font.Size > 2 Then Dec Label1.Font.Size Else Break  ' dont set the font size too small or it errors
  18.       Else
  19.         Break
  20.       Endif
  21.     Loop
  23.  
  25.  
  26.  

you could also probably use a PictureBox and paint the text to a picture then have the PictureBox.Stretch enabled to make it fit.

 Thanks Bruce, I like the PictureBox idea. I'll do some experimentation as there are 110 separate LCDlables or Labels.

Or something like this..
Then any label who's name is like "SLabel*" gets stretched.

Code (gambas)

  1. Public Sub Form_Resize()
  2.  
  3.   For Each o As Object In Me.Controls
  4.     If o.Name Like "SLabel*" Then ResizeLabel(o)
  5.   Next
  6.  
  8.  
  9. Public Sub ResizeLabel(Lbl As Label)
  10.  
  11.   With Lbl
  12.   ' if label text height or width is less than the label size then increase Font.Size
  13.   If .Font.Height < .Height And If .Font.TextWidth(.Text) < .W Then
  14.     Do
  15.       If .Font.Height + 1 < .Height And If .Font.TextWidth(.Text) + 1 < .W Then
  16.         Inc .Font.Size
  17.       Else
  18.         Break
  19.       Endif
  20.     Loop
  21.   ' if label text height or width is more than the label size then decrease Font.Size
  22.   Else If .Font.Height > .Height Or If .Font.TextWidth(.Text) > .W Then
  23.     Do
  24.       If .Font.Height > .Height Or If .Font.TextWidth(.Text) > .W Then
  25.         If .Font.Size > 2 Then Dec .Font.Size Else Break
  26.       Else
  27.         Break
  28.       Endif
  29.     Loop
  31.  
  33.  
  35.  

Could be easier than converting all into pictureboxes
If naming is like Label1 , Label2, etc you just add S to the start of the Label names you want to stretch.

This is the progress so far, still using LCDLabels, just what you need to fill a cold winter's afternoon! Welcome to the WordClock. I based it on a clock I saw in a friend's house. Have a look at the price here?!!
