Borderless window but taskbar behaves as normal?

[Seymour Clufley]

On Windows, the default behaviour is that clicking on an app in the taskbar will toggle the app's window size. If it is minimised, it will maximise. If it is maximised, it will minimise. With PB, in order to have this default behaviour, you need to add the minimise gadget:

Code: Select all

win = OpenWindow(#PB_Any,0,0,900,600, "test",#PB_Window_MinimizeGadget)

The issue I'm facing is that the window needs to be borderless - no titlebar, and therefore no minimise gadget. Is there any way to have a borderless window that has the default taskbar behaviour?

Seems to work by adding #WS_MINIMIZEBOX Style on the BorderLess Window:

Code: Select all

EnableExplicit

Enumeration Window
  #Window_0
EndEnumeration

Enumeration Gadgets
  #Btn_1
EndEnumeration

Enumeration Shortcut
  #Shortcut_Escape = 3
EndEnumeration

If OpenWindow(#Window_0, 0, 0, 240, 140, "Title", #PB_Window_BorderLess)
  SetWindowLongPtr_(WindowID(#Window_0), #GWL_STYLE, GetWindowLongPtr_(WindowID(#Window_0), #GWL_STYLE) | #WS_MINIMIZEBOX)
  ButtonGadget(#Btn_1, 20, 20, 200, 100, "Button_1")
  AddKeyboardShortcut(#Window_0, #PB_Shortcut_Escape, #Shortcut_Escape)
  
  Repeat : Until WaitWindowEvent() = #PB_Event_Menu And EventMenu() = #Shortcut_Escape
EndIf

That's perfect, Chris. Thank you very much.

You're welcome, I could see the use for me too.
I had tried with PB_Event_ActivateWindow, ShowWindow_(hWnd, #SW_SHOWMINNOACTIVE),... but without any result.
On a second thought, this is indeed the solution here: it works as if the Minimize button were there (with its associated functions), but without displaying it.
And I wonder whether it should be a feature request ?
After all, the default behavior of the taskbar buttons should be the same whether the window is borderless or not.

I agree, the taskbar button should behave consistently. And this behaviour is normal, so I'm sure most people would want it for their programs.

Very interesting !

The feature request is here.
