[Natter]

Hi,

I need to show a text string, each character of which has its own color. Is it possible to do this on FW ?

In addition, this can be done on WebView and RichEdit.
No, these are not interesting solutions

I need to show a text string, each character of which has its own color. Is it possible to do this on FW ?

Code: Select all  Expand view  RUN

#include "fivewin.ch"
#define DT_SINGLELINE      32
#define DT_CALCRECT  1024

function Main()

   local cText := "MULTI-COLOR TEXT"
   local oDlg, oBar, oFont

   local aColors  := { ;
   METRO_LIME, METRO_GREEN, METRO_EMERALD, METRO_TEAL, METRO_CYAN,      ;
   METRO_COBALT, METRO_INDIGO, METRO_VIOLET, METRO_PINK, METRO_MAGENTA, ;
   METRO_CRIMSON, METRO_RED, METRO_ORANGE, METRO_AMBER, METRO_YELLOW,   ;

         DrawTextEx( hDC, c, aRect, DT_SINGLELINE + DT_CALCRECT, oFont:hFont, aColors[ n ], @nRight )
         DrawTextEx( hDC, c, aRect, DT_SINGLELINE, oFont:hFont, aColors[ n ] )

      next
      SetBkMode( hDC, bk )

      return nil
      >

   oDlg:bInit  := <||
      SET MESSAGE OF oDlg TO "Color Text" CENTER 2007
      return nil
      >

   ACTIVATE DIALOG oDlg CENTERED
   RELEASE FONT oFont

return nil
 

This is the main logic

Code: Select all  Expand view  RUN

     for n := 1 to Len( cText )
         c  := SubStr( cText, n, 1 )
         DrawTextEx( hDC, c, aRect, DT_SINGLELINE + DT_CALCRECT, oFont:hFont, aColors[ n ], @nRight )
         DrawTextEx( hDC, c, aRect, DT_SINGLELINE, oFont:hFont, aColors[ n ] )
         aRect[ 2 ] := nRight
      next

Rao, thank you very much, a beautiful solution !!

Great

the Main Logic also run under HMG
