How to display coloured emoticons embedded in text in Purebasic Gadgets?

[sverson]

How can I display coloured emoticons embedded in the text in Purebasic?
For me it only works in black and white in all gadgets.



I have hundreds of comments with emoticons in a database and want to display them correctly (in colour!).
This should also work somehow with the ListIconGadget. Not only LibreOffice Calc but also the DB Browser for SQLite (https://sqlitebrowser.org/) can do this - and of course MS Word.

I am happy to receive suggestions

you can in scintilla on windows 10 11 with
ScintillaSendMessage(0,#SCI_SETTECHNOLOGY, #SC_TECHNOLOGY_DIRECTWRITE)

Code: Select all

Procedure.s _Chr(v.i) ;return a proper surrogate pair for unicode values outside the BMP (Basic Multilingual Plane)
  
  Protected chr.q
  If v < $10000
    ProcedureReturn Chr(v)
  Else
    chr = (v&$3FF)<<16 | (v-$10000)>>10 | $DC00D800
    ProcedureReturn PeekS(@chr, 2, #PB_Unicode)
  EndIf
  
EndProcedure

If OpenWindow(0, 0, 0, 600, 200, "ScintillaGadget", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
  
    
  ScintillaGadget(0, 10, 10, 580, 180, 0)
    
  ScintillaSendMessage(0,#SCI_SETTECHNOLOGY, #SC_TECHNOLOGY_DIRECTWRITE) ;<---this does the job
  
  ; Output set to red color
  ScintillaSendMessage(0, #SCI_STYLESETFORE, 0, RGB(255, 0, 0))
  ScintillaSendMessage(Gadget, #SCI_STYLESETFONT,#STYLE_DEFAULT, @"Segoe UI")      
  ScintillaSendMessage(Gadget, #SCI_STYLESETSIZE, #STYLE_DEFAULT, 18)                     
    
  ; Set the initial text to the ScintillaGadget
  *Text=UTF8("This is a simple ScintillaGadget with text..." + _Chr($1f60e))
  ScintillaSendMessage(0, #SCI_SETTEXT, 0, *Text)
  FreeMemory(*Text) ; The buffer made by UTF8() has to be freed, to avoid memory leak
  
  ; Adding a second line of text with linebreak before
  Text$ = Chr(10) + "Second line"
  *Text=UTF8(Text$)
  ScintillaSendMessage(0, #SCI_APPENDTEXT, Len(Text$), *Text)
  FreeMemory(*Text)
  
  Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow
EndIf

Thx idle.

So scintilla is the only way to handle this issue?
If so, I would have to create some kind of ListIconGadget from ScintillaGadgets.
That's going to be a pretty big deal when you have to process 11 columns and thousands of rows.

I assume this solution will be pretty slow. The "DB Browser for SQLite" (Windows) is not slow at all but still can display coloured enoticons within text.

Yes currently scintilla is the only gadget that supports it. if you want a searchable structure
you can either use a webgadget and html table or embed pngs or icons in a DS and map by name or a trie
see here https://www.purebasic.fr/english/viewtopic.php?t=84306
there's a link to create icons
