Hi folks

Please accept my sincere apologies if these two questions have come up before. I have desperately searched the forum but to no avail - maybe I've just missed it. Many thanks for any assistance.

I've noticed that the ListIconGadget information in the PB help features a screenshot which shows a sorting arrow in the first column. Is this now possible with a simple flag or does one still need to write an extensive bit of code to activate this feature?

Also, is there a Minimize event for a window - maybe along the lines of #PB_Event_MinimizeWindow? I've seen references to #WM_ events as well. Are people getting this information from the WinAPI references as I cannot find them in the PB manual?

Thanks for listening.

Hi

Further to that, I've found IsIconic_(hWnd) in the APIGuide which seems to work but only tests to see if the window is minimized - it doesn't actually respond to the clicking of the minimize gadget.

Cheers

Hey Stephen, you could always use CloseWindow_()

MS Platform SDK says: The CloseWindow function minimizes (but does not destroy) the specified window.

So...

Code: Select all

#Win=0
#Button=1

If OpenWindow(#Win,0,0,400,300,#PB_Window_SystemMenu|#PB_Window_ScreenCentered,"Test")
  If CreateGadgetList(WindowID())
    ButtonGadget(#Button,10,10,50,20,"Minimize")
  EndIf

  Repeat
    eventid=WaitWindowEvent()
    If eventid=#PB_Event_Gadget
      If EventGadgetID()=#Button
        CloseWindow_(WindowID(#Win))
      EndIf
    EndIf
  Until eventid=#PB_Event_CloseWindow
EndIf
End

Hi Paul

Thanks for that. What I wanted to do was this:

1) User clicks Minimize button on window titlebar
2) Window disappears
3) SysTray icon is created

That's why I wanted to check for the Minimize event. Rather than have a button do it - I wanted to use the provided window gadget and respond to the event by creating a SysTray icon.

However, I have managed to get it to work by using the API function IsIconic. All I did was wait for a window event and then check to see if the window had been minimized (iconified).

If OpenWindow((#Window_Form1,0,0,400,300,#PB_Window_SystemMenu|#PB_Window_ScreenCentered,"Test")

Repeat
EventID=WaitWindowEvent()
Select EventID

winIconic = IsIconic_(hWnd)
If winIconic 0 ;the window has been minimized
HideWindow(#Window_Form1, 1)
AddSysTrayIcon(1, hWnd, LoadIcon_(0, #IDI_QUESTION))
EndIf

Case #PB_Event_SysTray
RemoveSysTrayIcon(1)
HideWindow(#Window_Form1, 0)
winFocus = SetForegroundWindow_(hWnd) ;un-hiding the window doesn't bring it to the front

Until eventid=#PB_Event_CloseWindow
EndIf
End

Sorry if the above code is a little messy - I'm still learning and refining. Seems to work pretty well though. Thanks for taking the time to respond Paul, it is greatly appreciated. Er... haven't got any ideas on that ListIconGadget prob have you?

All the best

Hi Steve,
don't know which OS you used, but under XP it's not working @ all.
For learning purposes some hints...
1.) Constant #Window_Form1 was not declared
2.) You have two brackets: If OpenWindow((#Window_Form1 ...
3.) You also didn't declare the variable hWnd

Regarding your comment on SetForegroundWindow:
SetForegroundWindow_(hWnd) ;un-hiding the window doesn't bring it to the front
this is because hWnd isn't declared properly.

Here the working code:

Code: Select all

#Window_Form1 = 1 : #SysTrayIcon = 1 ; declare the constants

If OpenWindow(#Window_Form1,0,0,400,300,#PB_Window_SystemMenu|#PB_Window_MinimizeGadget|#PB_Window_ScreenCentered,"Test")

  hWnd = WindowID()

  Repeat
    EventID=WaitWindowEvent()
    Select EventID

      If IsIconic_(hWnd)  0 ;the window has been minimized
        HideWindow(#Window_Form1, 1)
        AddSysTrayIcon(#SysTrayIcon, hWnd, LoadIcon_(0, #IDI_QUESTION))
      EndIf

      Case #PB_Event_SysTray
        RemoveSysTrayIcon(#SysTrayIcon)
        HideWindow(#Window_Form1, 0)
        SetForegroundWindow_(hWnd) ;un-hiding the window brings it to the front

    EndSelect

  Until EventID = #PB_Event_CloseWindow

EndIf

End

Have a nice day...

Hi Franco

Sorry, I didn't make that clear - the code I supplied is only a snippet of my program and was only intended to show the code and not be cut, pasted and compiled in PB. It definitely will not work without the rest of my code. hWnd is defined in the procedure that defines the window and gadgets.

I'll make sure in future that any demos of code I post can be run as they are. My mistake for which I apologise.

Kale, thanks for that. Actually, the guy who wrote the Finance Tracker has helped me considerably by providing the program source code (not to be ripped but to be used as a base for learning I might add). I've seen code that performs the searching based on column clicks but without the arrow. I just wondered if there was a nice simple flag that could be used instead.

Anyhow, thanks everyone for the help - it is greatly appreciated.

All the best
Steve White
