Wordaround found! With the help of the list-archive¹ and the source-code of Pidgin² written in GTK+. Below I added the relevant code that made things work. For short the behaviour. Clicking on statusicon lets my main window disappear, if visible in the taskbar. It minimizes to taskbar and afterwards the taskbar entry disappears too. When not visibile, the taskbar entry appears with animation the window appears without animation. Same behaviour like on linux. How it works: On win32 I no longer check get_skip_taskbar_hint() instead I use the win32-API IsWindowVisible() but before I have to extract the window handler from my main window. After minimizing with iconify() I call win32-API ShowWindow()³ with flag SW_HIDE. This lets disappear the window and taskbar entry as well, but minimizes it before. For letting my main window pop-up again I'm still experimentating, if all code lines are nessecary (deiconify() and present()). Further detail: Statusicon ist a member of MainWindow class and smart pointer Remark: Haven't made any sophiticated test. If I recognize a problem, I'll report.
