rich text editor examples?

[hagibaba]

Hi, I'm stuck.

Are there any code examples of how to create a rich text editor inside a scroll area, inside a splitter gadget with a listviewgadget to the right side. I've got some of my old code converted to PB 4 but now it's just driving me nuts and I want to start from scratch... I hope you understood that. Thanks.

Never mind, I'll figure it out myself. I just had a little panic attack. Damn StickyWindow command.

Ok, here's a sane question... or is it?

How can I put a Win32 richedit window into a splitter gadget?

Code: Select all

  If OpenWindow(0, 0, 0, 230, 180, "SplitterGadget", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
    If CreateGadgetList(WindowID(0))
      
      #ListViewGadget  = 1 
      #Splitter = 2
      
      RichEditGadget = CreateWindowEx_(#WS_EX_WINDOWEDGE,"RichEdit20A",0,#Flags, 0, 0, 0, 0, WindowID(0), #GADGET_RICHTEXT, GetModuleHandle_(0), 0)
      ListViewGadget(#ListViewGadget, 10, 10, 250, 120)
      SplitterGadget(#Splitter, 5, 5, 220, 120, RichEditGadget, #ListViewGadget, #PB_Splitter_Separator)
            
      Repeat 
      Until WaitWindowEvent() = #PB_Event_CloseWindow
    EndIf
  EndIf

I think your problem may have to do with HOW you created your rich edit gadget...

Though I can'tt see why you would want to do this.

Code: Select all

Enumeration
 #ListViewGadget0
 #ListViewGadget1
 #Splitter
EndEnumeration

If OpenWindow(0, 0, 0, 230, 180, "SplitterGadget", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
    If CreateGadgetList(WindowID(0))
          
      ListViewGadget(#ListViewGadget0, 0, 0, 0, 0) 
      ListViewGadget(#ListViewGadget1, 0, 0, 0, 0) 
      SplitterGadget(#Splitter, 5, 5, 220, 120, #ListViewGadget0, #ListViewGadget1, #PB_Splitter_Separator)
            
      TextGadget(3, 10, 135, 210, 40, "Above GUI part shows two automatically resizing buttons inside the 230x130 SplitterGadget area.",#PB_Text_Center )
      
      Repeat 
      Until WaitWindowEvent() = #PB_Event_CloseWindow
    EndIf
  EndIf

Why not use PB's EditorGadget in place of API RichEdit20A?

Yes, I use a PB editor gadget in a splitter and everything seems to work fine.

I don't know much about the editor gadget. The help file doesn't even say it's a rich text gadget. Where can I find out more about the editor gadget? Is there a limit to how much text it can contain? I use the RichEdit dll for 2 reasons:
1. All the old code is written for the RichEdit window.
2. I know it opens very large text files, several MBs.

PB's EditorGadget is a RichEdit control on Windows (class = "RichEdit20A" here on NT4).
So you can use any code written for RicheEdit controls, with #EM_* messages, #EN_* notifications, etc...

Large files should not be a problem as long as you extend the default 32,767 text limit with

Code: Select all

SendMessage_(GadgetID(#EditorGadget), #EM_LIMITTEXT, -1, 0)

SendMessage_(GadgetID(#EditorGadget), #EM_LIMITTEXT, -1, 0)

Mighty nice to know.

Thanks.

You're welcome. I don't remember who I picked that one up from... most likely it was freak.

Yay! This is what I was hoping. Thanks gnozal.

Thanks for the tip Sparkie.

I'm now rewriting the program to use the EditorGadget.
