[Rimantas]

Hi,

can I use png in toolbars , btnbmps ? If yes , how ? Through TImage class ? Or I must convert png to bmps ?

With best regards !

On another note, what are the image files that FWH can read directly without having to do any conversion? Only gif, bmp and png? Is jpg already supported?

Thanks Uwe ! I didn't found this . This discused on May of 2011 . Maybe alreday it implemented in Fwh as standard ?

Loading of PNG files now is OK . It leaves one problem . I want to did Toolbar and images I'm loading from png . Here is a sample :

Code: Select all  Expand view  RUN

   ...
   DEFINE IMAGELIST oImageList SIZE 28, 28
   oImageList:Add( TBitmap():Define( , cKelias_bmp + "copy.png", oWndPagr ), ;
   TBitmap():Define( , cKelias_bmp + "disabled\copy.png", oWndPagr ) )
   oImageList:Add( TBitmap():Define( , cKelias_bmp + "cut.png", oWndPagr ), ;
   TBitmap():Define( , cKelias_bmp + "disabled\cut.png", oWndPagr ) )
   ...
 

I'm overriding Bitmaps define and ImageList add methods adding for png support . All is working OK .

The main problem that Toolbar button must have masked image - something like black image in white background . It's needfull ? I added png disabled for masked , but the black background didn't dissapears ... How it can be solved ?

Picture of the problem ...

Consider this code .. note you can use FILENAME or RESOURCE to call your icons... Your disabled icon ( second icon parameter ) needs to be a different image of the first .. only desaturated in greyscale as in the pictures below.

Code: Select all  Expand view  RUN

/*  use this code if you call by FILENAME  
DEFINE BUTTON oButt1 OF oBar FILENAME ( cDEFA+"\ICONS\BUILDING.BMP" ), ;
                                      ( cDEFA+"\ICONS\DBUILDING.BMP" ) ,( cDEFA+"\ICONS\DBUILDING.BMP" ) ;
MESSAGE "Property Information" ;
ACTION _PropBrow( oWnd,oBar )  ;
PROMPT "Property"
oButt1:cToolTip := { " " + CRLF + "Property Info", "Property Info", 1, CLR_BLACK, 14089979  }
*/

// use this code if you have imported your icons to .dll or compiled into your .exe
DEFINE BUTTON oButt1 OF oBar RESOURCE "BUILDING" , ;
                                      "DBUILDING", "DBUILDING"  ;
MESSAGE "Property Information" ;
ACTION _PropBrow( oWnd,oBar )  ;
PROMPT "Property"
oButt1:cToolTip := { " " + CRLF + "Property Info", "Property Info", 1, CLR_BLACK, 14089979  }

Rick,
I solved this problem - simply did bitmaps backgrounds in grayscale . Now it's OK .

With best regards !
