How to get and set the flag gadget?

That's the way that it does not work

Code: Select all

    If OpenWindow(1, 0, 0, 600, 440, "Split Picture", #PB_Window_ScreenCentered | #PB_Window_SystemMenu | #PB_Window_SizeGadget)

          s= GetWindowLong_(GadgetID(213), #GWL_STYLE)
         exs= GetWindowLong_(GadgetID(213), #GWL_EXSTYLE)

Some styles for certain controls can only be set at creation time. That is, once the control has been created, certain styles cannot be altered.

Because you are using API window styles with a Purebasic function. It all checks out.

The problem is that when you use #PB_Text_Border, Purebasic sets the #WS_EX_CLIENTEDGE extended style and not a regular window style. All you are seeing is a confusion between regular and extended styles that is all.

I am not saying that you cannot do what you are after with some controls, I am saying that some controls will not allow you to alter certain styles after they have been created.

For example, switching InvalidateRect_() for SetWindowPos_() in your original code works for borders :

Code: Select all

    If OpenWindow(1, 0, 0, 600, 440, "Split Picture", #PB_Window_ScreenCentered | #PB_Window_SystemMenu | #PB_Window_SizeGadget)
      StickyWindow(1, 1)
     
     
         TextGadget(213, 95, 10, 60, 25, "TextGadget",#PB_Text_Border)
          s= GetWindowLong_(GadgetID(213), #GWL_STYLE)
         exs= GetWindowLong_(GadgetID(213), #GWL_EXSTYLE)
        
         
         
        TextGadget(214, 95, 110, 60, 25, "TextGadget",0)
        SetWindowLong_(GadgetID (214), #GWL_STYLE,  s)
        SetWindowLong_(GadgetID (214), #GWL_EXSTYLE,  exs)
        SetWindowPos_(GadgetID(214), 0, 0, 0, 0, 0, #SWP_FRAMECHANGED|#SWP_DRAWFRAME|#SWP_NOMOVE|#SWP_NOSIZE|#SWP_NOZORDER)

       
      EndIf
       
    Repeat
      Event=WaitWindowEvent()
     
      If Event=#PB_Event_CloseWindow And EventWindow()=1
      End
     EndIf
    ForEver

However, change #PB_Text_Border to #PB_Text_Right and it does not work. Text justification is one of those things that Windows will not allow you to alter after the text gadget has been created.

Or how else to make the procedures?

[srod]

I might be willing to help if you explained what those functions are supposed to do; just looks completely superfluous to me and almost nonsensical? Beside's the code crashes here!

I have already explained and demonstrated how to achieve what you were originally trying to do and explained the limitations of this approach. It is a hack at best.
