Is there a way to change the caption

[Mike Schneider]

Is there a way to change the caption of a graphics window...

i.e. one creates a graphic window as such...

GRAPHIC WINDOW "Box", 300, 300, 130, 130 TO hWin

then later, as the program is running I want to change the word "Box" to
the variable name$.

Please advise...

Thanks,

Mike...

Use

SetWindowText(hWin, szNewCaption)

with szNewCaption being an Asciiz string.

I can't get this to work in a graphic window.

I also tried CONSOLE NAME "My program"

Thanks for any help!

Could you show the code, or something compilable that you think would work but doesn't.
If you are doing something wrong someone will find it, and/or if there is an issue it can be documented(sent to support).

Hello Doug, that example is an windows API, but it will work in pbcc graphics, you'll have to include the windows api like I'm showing. I'm using the Same example from last time.

#COMPILE EXE
#DIM ALL
#INCLUDE "C:\PBCC40\WINAPI\WIN32API.INC"

FUNCTION PBMAIN () AS LONG
  LOCAL NewCaption AS ASCIIZ * 40
  LOCAL hGWin AS DWORD
  LOCAL t AS STRING

  GRAPHIC WINDOW "Undraw test...",0,0,800,600 TO hgwin
  GRAPHIC ATTACH hGWin, 0, REDRAW
  NewCaption = "Howdy Folks"
  SetWindowText(hgWin, NewCaption)

  GRAPHIC SET POS (200,300)
  GRAPHIC PRINT "Now is the time for all good men to come to the aid of their country"
  GRAPHIC SET POS (200,340)
  GRAPHIC PRINT "The quick red fox jumped over the lazy dogs back many times."
  GRAPHIC SET POS (200,380)
  GRAPHIC PRINT "Now is the time for all good men to come to the aid of their country"
  GRAPHIC REDRAW
  SLEEP 3000

  GRAPHIC SET MIX %MIX_NOTXORSRC
  GRAPHIC LINE (200,200)-(600,500)
  GRAPHIC REDRAW
  SLEEP 4000

  GRAPHIC LINE (200,200)-(600,500)
  GRAPHIC REDRAW

  ' restore the default mode...
  GRAPHIC SET MIX %MIX_COPYSRC

  GRAPHIC SET FOCUS
  
  NewCaption = "Goodbye Friends"
  SetWindowText(hgWin, NewCaption)
                                  
  SLEEP 4000

  GRAPHIC WINDOW END

END FUNCTION

Jerry - once again thanks!
I didn't include the win32api file - that was it!

Any ideas on how to create/display a custom icon on the caption line?

License PB/Windows and learn how to write real GUI programs?

[Edwin Knoppert]

You can do that with PB/CC.
Console off and SDK stuff.

[Michael Mattias]

on me. You don't need to license PB/Windows to create real GUI programs....

I do have PBWin... but that wasn't the question.
This is for a CC ap.

Looks like it isn't normally possible to change the icon of a Graphic Window. Here's a technique though for setting the icon while the window is being created..

#DIM ALL
#INCLUDE "WIN32API.INC"
GLOBAL hHook???
 
FUNCTION HookGFXWindow(BYVAL lMsg AS DWORD, BYVAL wParam AS DWORD, BYVAL lParam AS LONG) AS LONG
 DIM hIcon???
 
  IF lMsg = %HCBT_CREATEWND THEN      ' wParam has handle of Window about to be created
    UnhookWindowsHookEx hHook
    'hIcon = LoadImage(BYVAL %NULL, "Objects.ico", %IMAGE_ICON, 16, 16, %LR_LOADFROMFILE )    ' your icon
    hIcon = LoadIcon(BYVAL %NULL, BYVAL %IDI_EXCLAMATION)       ' std icon - comment out if using your own
    SetClassLong wParam, %GCL_HICONSM, hIcon
  END IF
 
 FUNCTION = 0
END FUNCTION
'------------------/HookGFXWindow
 
FUNCTION PBMAIN()
 DIM gWdw???
 
  hHook = SetWindowsHookEx(%WH_CBT, CODEPTR(HookGFXWindow), GetModuleHandle(""), 0)
  GRAPHIC WINDOW "Test GFX Window", 200, 200, 350, 200 TO gWdw
 
  GRAPHIC ATTACH gWdw, 0
  GRAPHIC PRINT
  GRAPHIC PRINT "  Window title can be a string literal or an asciiz string (variable)"
  SLEEP 1000
 
  SetWindowText gWdw, "** Check out the fancy Icon ! **"   ' <- String literal works ok here
  GRAPHIC WAITKEY$
 
  GRAPHIC WINDOW END
 
END FUNCTION
'------------------/PBMain

So is the linked demo. That compiles and runs 'as is' using either PB/WIN or PB/CC.

That is, instead of a call to GRAPHIC WINDOW et al, maybe a call to CreateWindowEx would be more appropos for this application.

It's an idea. Use it or not.

[Edwin Knoppert]

This is a simple and not profi example but works:
SendMessage( hgWin, %WM_SETICON, %ICON_BIG, LoadIcon( 0, ByVal %IDI_EXCLAMATION ) )
SendMessage( hgWin, %WM_SETICON, %ICON_SMALL, LoadIcon( 0, ByVal %IDI_EXCLAMATION ) )

Notes:
You should use LoadImage() and use real big *and* small icons.
Custom icon handles should be freed.

[Dave Biggs]

Edwin is right. (Naturally )

SendMessage( hgWin, %WM_SETICON, %ICON_BIG, LoadIcon( 0, ByVal %IDI_EXCLAMATION ) )
SendMessage( hgWin, %WM_SETICON, %ICON_SMALL, LoadIcon( 0, ByVal %IDI_EXCLAMATION ) )

The solution I posted also works but is OTT.

Sendmessage is better (using LoadImage )
