Add bitmap to taskbar

[reds]

I would like to show wi-fi signal status icon on the taskbar rather than within the app window is it possible ?

TIA
Peter
p.s. running WM6.1

I would like to place the 5 bar icon currently at at top right of the screen onto the taskbar next to the title,
in this example WiFi Status

Thanks
Peter

p.s. preview of message not showing photo but it is at https://imgur.com/a/Ssb1E

Peter,

Are you creating that Wifi status window using FWPPC ?

If so, could you please post the code here ?

I guess that if we use the WM_NCPAINT message then you may be able to paint anything you need on the caption bar

Code was found here or another forum, I can't remember now

Peter,

ok, thanks

So in your PRG you call Signal() and then paint the wifi icon, right ?

Please post here the PRG code used to paint the wifi icon too so we can modify it to be painted in the caption area, thanks

Here it is

#include "FWCE.ch"

Peter,

Please try your example with these changes and let me know if you get a beep, thanks

replace this line:

DEFINE WINDOW oWnd TITLE "WiFi Status"

with:

oWnd = TMyWindow():New( "WiFi Status" )

and add this code to your prg:

Code: Select all

#define WM_NCPAINT           133    // 0x085

CLASS TMyWindow FROM TWindow

   METHOD HandleEvent( nMsg, nWParam, nLParam )

ENDCLASS

METHOD HandleEvent( nMsg, nWParam, nLParam ) CLASS TMyWindow

   if nMsg == WM_NCPAINT
      MsgBeep()
   endif
      
return Super:HandleEvent( nMsg, nWParam, nLParam )

Antonio

MsgBeep() does not get called and then crashes with variable does not exist Super


Regards
Peter

[Antonio Linares]

Please use ::Super instead of Super

[reds]

MsgBeep() still not called
