#86 Option for sized backgroud bitmap on window main.

[Itamar M. Lins Jr.]

Hi!
It would be nice to have this option!
Adjust the size of the bmp image in the background.

#xcommand INIT WINDOW <oWnd>                ;
             [ MAIN ]                       ;
             [<lMdi: MDI>]                  ;
             [ APPNAME <appname> ]          ;
             [ TITLE <cTitle> ]             ;
             [ AT <x>, <y> ]                ;
             [ SIZE <width>, <height> ]     ;
             [ ICON <ico> ]                 ;
             [ SYSCOLOR <clr> ]             ;
             [ <bclr: BACKCOLOR, COLOR> <bcolor> ] ;
             [ BACKGROUND BITMAP <oBmp> ]   ; //here BACKGROUND BITMAP <oBmp> SIZE <width>, <height> ]
...

Best regards,

Hello Itamar,
i think, this modification in the HWGUI code is not necessary.
because HBitmap():AddFile() resizes a bitmap image.

See sample program
samples\stretch.prg

I have done some modifications,
added a hexdump of "hwgui.bmp" and
some more comments.

First the bitmap object is created with the desired size:

Free this (line 44)
Bmp := HBitmap():AddFile(cImageMain,,.F.,hwg_Getdesktopwidth(),hwg_Getdesktopheight()-21)
and comment out:
// oBmp := HBitmap():AddFile( cImageMain,, .F., 301, 160 )

Call the sample without any command line options
and the following command is called:
INIT WINDOW oFormMain MAIN AT 0,0 SIZE nPosX , nPosY

call program with
stretch.exe X (LINUX: ./stretch X)
and the command is called with BACKGROUND BITMAP option:
INIT WINDOW oFormMain APPNAME "Agenda Hwgui" MAIN AT 0,0 SIZE nPosX,nPosY BACKGROUND BITMAP oBmp

There are bugs in methods AddFile()
and AddString() of HBitmap class,
need to be fixed.
Only Addfile() on WinAPI stretches the bitmap
correct.

Please be patient. I'll look for the code.

Hello Itamar,
with commit r3539 i added the size parameters for
AddFile() method. Please check.
Now it is the same as WinAPI.

Now i will search a solution for AddString(),
for GTK i found a solution, need to search same for WinAPI.

Hello Itamar,
with commit r3540 i added the size parameters for
AddString() method of HBitmap class for GTK. Please check.
I think, for a LINUX user it is OK.

Need to continue with AddString() for WinAPI.
Please give feedback for closing this ticket.

Hello Itamar,
now after some days of programming i present the
solution for WinAPI.
Committed with r3541

See sample program
samples\stretch.prg
for new details.

The new main resizing funktion is
hwg_Stretch_BMP_i(cbmp, clocname, nWidth, nHeight )
and could also be used for other purposes.
But need to port it for LINUX for multi platform usage,
that i will do it during the next few days.

Start program with
stretch.exe X (LINUX: ./stretch X)
and the command is called with BACKGROUND BITMAP option:
INIT WINDOW oFormMain APPNAME "Agenda Hwgui" MAIN AT 0,0 SIZE nPosX,nPosY BACKGROUND BITMAP oBmp

I added some helpful debugging functions and
also upated the HWGUI class and function documentation.

I will test in the WinPRN sample to
stretch the QR code in the printout.

Please check the code and give feedback,
if the ticket can be closed.
