Hello friends,
i try following coding:

; Unsichtbares Fenster, um nur den Systray anzuzeigen
  OpenWindow(0, 0, 0, 10, 10, "", #PB_Window_Invisible)
  UsePNGImageDecoder()
  AddSysTrayIcon(0, WindowID(0), LoadImage(0, #PB_Compiler_Home + "examples/sources/Data/world.png"))
  ; Erstellt ein Popup-Menü, das im Systray im Systray-Look angezeigt wird
  CreatePopupImageMenu(0, #PB_Menu_SysTrayLook)
    MenuItem(0, "About PureBasic...")
    MenuBar()
    MenuItem(1, "Exit")
  ; Verknüpft das Menü mit dem Systray
;   SysTrayIconMenu(0, MenuID(0))
  Repeat
    Select WaitWindowEvent()
      Case #PB_Event_SysTray
        Debug "#PB_Event_SysTray"   
        
      Case #PB_Event_Menu
        Select EventMenu()
          Case 1 ; Exit 
            RemoveSysTrayIcon(0)
            End
        EndSelect
    EndSelect
  ForEver

The result is:

[00:02:58] Warte auf den Start des Executable...
[00:02:58] Executable-Typ: Linux - x64 (64bit, Unicode, Purifier)
[00:02:58] Executable gestartet.

[00:03:04] Das Programm wurde beendet.

I cannot understand it. The first is: no reaction on the var <#PB_Event_SysTray> and then the message
Gdk (CRITICAL): gdk_window_thaw_toplevel_updates: assertion 'window->update_and_descendants_freeze_count > 0' failed
What means the compiler with this messages????

Can anybody explain me this message?! And the net is: I cannot use the version 6.10, because i query this interrupt "#PB_Event_SysTray" in a lot of progams. An this does not exist for Purebasic 6.10

Thanks for any help.

Ingo

Code: Select all

Gdk (CRITICAL): gdk_window_thaw_toplevel_updates: assertion 'window->update_and_descendants_freeze_count > 0' failed

You can ignore this message. Only occurs sometimes and depending on the linux distribution.

The second point is more difficult:
With the last GTK3 version, the old GTK internal Systray was finally removed from the GTK3 system.
So a replacement had to be found. This is the much used libappindicator3-1. This is now also used by PureBasic v6.10.
However, this does not provide a mouse click event and only the possibility to connect a menu. The 'scroll-event' is supported, but I don't know what this is good for.

How the libappindicator works and what is possible, you can see with my example.

To move to doc. The Systray event is no more supported on Linux, a menu is needed to interact with it.+

@Fred should take a look, which notes should be added to the docs...
