Hello,

I don't understand why nothing happens when I select window or if I close a window, the whole program closes ?! Thanks in advance !

Code: Select all

@DISPLAY 1, {X=50,Y=150, Width=100, Height=100,color=#WHITE}

Win1=CreateDisplay(NIL, {X=50,Width=200, Height=200,color=$FF0000})   OpenDisplay(Win1)
Win2=CreateDisplay(NIL, {X=300,Width=200, Height=200, color=$00FF00}) OpenDisplay(Win2)
Win3=CreateDisplay(NIL, {X=550,Width=200, Height=200, color=$0000FF}) OpenDisplay(Win3)

Function  p_EventFunc(msg)
    Switch msg.action
    CASE "ActiveWindow": DebugPrint(msg.id)
    CASE "CloseWindow":  DebugPrint(msg.id)
    EndSwitch
EndFunction

; listen to these events!
InstallEventHandler({CloseWindow = p_EventFunc, ActiveWindow = p_EventFunc})

EscapeQuit(True)

; Boucle infinie
Repeat
        WaitEvent
Forever

Window related event handlers are per display, so you must install handlers for each display separately. Now you have only installed them for the last display/window.

This should do the trick:

Code: Select all

; listen to these events!
InstallEventHandler({CloseWindow = p_EventFunc, ActiveWindow = p_EventFunc})
SelectDisplay(1)
InstallEventHandler({CloseWindow = p_EventFunc, ActiveWindow = p_EventFunc})
SelectDisplay(Win1)
InstallEventHandler({CloseWindow = p_EventFunc, ActiveWindow = p_EventFunc})
SelectDisplay(Win2)
InstallEventHandler({CloseWindow = p_EventFunc, ActiveWindow = p_EventFunc})
