With purebasic application all features of aero snap work except this one:

Vertically maximize a window with Aero Snap by resizing the window to the edge of the screen

My question: How to make vertical maximize to work with purebasic application? I'm guessing that i will need callback to detect resize to edge of the screen and then return something to OS that will handle this feature...
It's not working with default window created like this:

Code: Select all

If OpenWindow(0, 100, 200, 195, 260, "PureBasic Window", #PB_Window_SystemMenu | #PB_Window_MinimizeGadget | #PB_Window_MaximizeGadget | #PB_Window_SizeGadget)
  
  Repeat
    Event = WaitWindowEvent()
    
    If Event = #PB_Event_CloseWindow
      Quit = 1
    EndIf
    
  Until Quit = 1
  
EndIf

Thanks for any help

Hello cas

Sol. #1

Code: Select all

Global wr.RECT

Procedure WinProc(hwnd, msg, wparam, lparam)
 GetWindowRect_(WindowID(0), wr)
  result=#PB_ProcessPureBasicEvents
  Select msg
    Case #WM_SIZE,#WM_SIZING
      If wr\top = 0
        mouse_event_(#MOUSEEVENTF_LEFTDOWN,0,0,0,0)
        mouse_event_(#MOUSEEVENTF_LEFTUP	,0,0,0,0)
      EndIf
  EndSelect
  ProcedureReturn result
EndProcedure


hwnd = OpenWindow(0, 100, 200, 195, 260, "PureBasic Window", #PB_Window_SystemMenu | #PB_Window_MinimizeGadget | #PB_Window_MaximizeGadget | #PB_Window_SizeGadget)
SetWindowCallback(@WinProc(),0) 
  
  Repeat 
    Event = WaitWindowEvent() 
    
    If Event = #PB_Event_CloseWindow 
      Quit = 1 
    EndIf

Second one is working. The only way is to create window with CreateWindowEx_() like you did in second example.
Thanks

You mean it does not work at all or what?
It is not perfect I know(not according to ms planned) but it works here somehow
Win 7 RTM x64
PB v4.31 x64

and again with some modifications

Code: Select all

Global wr.RECT,desk.RECT

Procedure WinProc(hwnd, msg, wparam, lparam)
  GetWindowRect_(WindowID(0), wr)  
  result=#PB_ProcessPureBasicEvents
  Select msg
    Case #WM_SIZE,#WM_SIZING
      If wr\top = 0 Or wr\bottom = desk\bottom - 20
        mouse_event_(#MOUSEEVENTF_LEFTDOWN,0,0,0,0)
        mouse_event_(#MOUSEEVENTF_LEFTUP	,0,0,0,0)
      EndIf
      
    Case #WM_MOUSELEAVE
        mouse_event_(#MOUSEEVENTF_LEFTDOWN,0,0,0,0)
        mouse_event_(#MOUSEEVENTF_LEFTUP	,0,0,0,0)
  
  EndSelect
  ProcedureReturn result
EndProcedure

hwnd = OpenWindow(0, 100, 200, 195, 260, "PureBasic Window", #PB_Window_SystemMenu | #PB_Window_MinimizeGadget | #PB_Window_MaximizeGadget | #PB_Window_SizeGadget)
SystemParametersInfo_(#SPI_GETWORKAREA, 0, @desk.RECT, 0)
SetWindowCallback(@WinProc(),0) 
  
  Repeat 
    Event = WaitWindowEvent() 
    
    If Event = #PB_Event_CloseWindow 
      Quit = 1 
    EndIf 
    
  Until Quit = 1

Let me know cas if it is not working totally or what

It's working but it is instantaneously resizing window. It should wait for me to release mouse button and give aero outline preview of resized window.
Your snippet with CreateWindowEx_() works perfectly.

I know it is not perfect but I was worry @ simulating Mouse click code

Have a good day mate
