Hide window system buttons (minimize, maximize, close)?

Zsolt_Szalay · June 5, 2025, 10:34am

Hello!
I try to find a solution to hide the window system buttons, unfortunatelly I did not find any setup/simple solution to switch on/off something within the attributums which would operate.
Can you help me soemone? e.g simple login window where I don’t need the syetem buttons.
Now, I can warn the user if use e.g system close button during the login process, but it can be simplified by the hiding. Finally, I solved it by API functions, but realy hard to beleive, there is not a simpler solution…

HI,

to hide that buttons, when you select the window in designer, on properties tab you must put Frame type to None, and Caption must be empty

Hi,

Just clear the Window’s title

If you remove the SYSTEM attribute from the Window that gets rid of Close.
Remove MAX attribute that gets rid of Maxmize.
Remove the Icon to get rid of Minimize. You can also leave the Icon and make Minimize not work by in Event:Iconize doing a CYCLE.

From my list of code snips this one removes Minimize but leaves the Icon. I think can be changed to hide others.

RemoveMinButton.clw

! This way your Window can have a pretty Icon() but not a Minimize button that causes end users to lose the form

 MAP 
    RemoveMinButton() !Remove Minimize button on the Current Window so can have Icon() but no Minimize
    MinButtonHide(BOOL HideMinimize=True),BOOL,PROC !Hide Minimize button (False Unhide) on the Current Window. Returns True if state changed.
    
    MODULE('Win32')
      GetWindowLong(LONG HndWindow, LONG nIndex),LONG,PASCAL,DLL(1),NAME('GetWindowLongA')
      SetWindowLong(LONG HndWindow, LONG nIndex, LONG dwNewLong),LONG,PROC,PASCAL,DLL(1),NAME('SetWindowLongA')
    END
