Hi!

I've encountered a problem with a button gadget.
I tried to have an button with size 12x12 pixel and a font size of 6.
The layout is: button and string gadget in first row, then an editor
gadget.
Everything looks fine, but the button and the string gadget do
always have a minimum size of 24 pixel.

How can I get button/string with less than 24 pixel?
Example code:

Code: Select all

  #MainWindow

  #Button1
  #Text1
  #Editor1
EndEnumeration

Hi Lord

Width, Height (optional) The size (in pixels) of the #Dialog. If the size is smaller than the required size as defined in the XML (after layout calculation), then the required size will be used. If omitted, the size of the dialog will be the smallest size required.

I think we should have an explanation from Fred
Can't say if it's bug or not (It could be limitations)
Next is a workaround not perfect specially with resizing

Code: Select all

Yes, without resizing the window, the button and the
string gadget have the right width, but the box does'nt
have the right hight.
After window resize everything is messed up again.
