5974 :: question on autolayout in wNim

• oyster (orginal) [2020-02-24T07:15:24+01:00] view original

  in my simple code, there is a spacing of 50 between text control and frame border. However if I use

  H:|[label, groupText]|
  Run

  when run the EXE, I get

  
  E:\prg\nim\nim-1.0.6\lib\core\macros.nim(581) layout
  C:\Users\USER\.nimble\pkgs\wnim-0.10.1\wNim\private\wResizer.nim(52) addConstraint
  C:\Users\USER\.nimble\pkgs\wnim-0.10.1\wNim\private\kiwi\solver.nim(74) addConstraint
  Error: unhandled exception:  [UnsatisfiableConstraintException]
  Run

  so how to fix it? thanks

  import strutils, wNim
  
  let app = App()
  let frame = Frame()
  let panel = Panel(frame)
  let label = StaticText(panel, style=wBorderSimple, label=" ".repeat(20))
  let text = TextCtrl(panel)
  let btnClick = Button(panel, label="Click")
  let btnClose = Button(panel, label="Close")
  
  proc layout() =
    panel.autolayout """
      H:|{groupButton:[btnClick(btnClose)]-[btnClose]}|
      H:{groupText:|-50-[text]|}
      V:|[label]-[groupText]-[groupButton]|
      H:|[label, groupText]|
    """
  panel.wEvent_Size do (): layout()
  
  layout()
  frame.center()
  frame.show()
  app.mainLoop()
  Run

  I suppose you should ask on wNim's github issue tracker.

  Most probably a typo error in your layout proc()

  
  proc layout() =
    panel.autolayout """
      H:|{groupButton:[btnClick(btnClose)]-[btnClose]}|
      H:|{groupText:[-50-[text]]}|
      V:|[label]-[groupText]-[groupButton]|
      H:|[label, groupText]|
  Run

  This template works, at least no error after compilation. By the way not sure it is the layout you want.

  Your rule 2 and rule 4 have contradictions.

  Rule 2: |-50-[text]| Rule 4: |[text]|
