Inserting code into the Editor

yrreti · Post by **yrreti** » Sun Dec 09, 2007 8:53 pm

When using the Color picker from the Tools menu. You can find a color you want and then by just clicking
on the insert color button, it inserts the code right where you left the cursor at in the editor code window.
I would really appreciate learning how to do that. It's a neat feature that I would like to use in some programs
I'm using. I especially like the fact that it places the code right where you want it to be. And from an independently
running program too.
Any advice and code ideas or examples would be greatly appreciated.
Thank you for your help.

The colour picker isn't an independently running program.

Thanks for your reply, and ...
Woops

your right it's not. I've seen a few color pickers on the forum and even one that I put on the forum myself.
I guess I had those other programs on my mind when I asked the question. and should have thought about it more carefully
before asking that question. I kind of wanted to use my color picker program instead of the default one.
Is there a way that anyone might know of that it may be possible to code, to allow you to take something from one running app and
send it to another app with out manually copying and pasting?
Thanks for your input.

On the same topic,
how can I insert text into an editor gadget at the current cursor's position?

Code: Select all

OpenWindow(0,0,0,320,240,"",$CA0001)
CreateGadgetList(WindowID(0))
EditorGadget(0,0,0,320,200)
ButtonGadget(1,120,210,80,20,"Add France")
SetGadgetText(0, "The rain in Spain falls mainly on the plain.")

Repeat
  ev = WaitWindowEvent()
  Select ev
    Case #PB_Event_Gadget
      Select EventGadget()
        Case 1
          SetActiveGadget(0)
          SendMessage_(GadgetID(0), #EM_SETSEL, 18,18)
          SendMessage_(GadgetID(0), #EM_REPLACESEL, 1, @" and France ")
      EndSelect
  EndSelect
Until ev = #WM_CLOSE

Beat me by precisely 3.2 seconds!

Thanks, yes, I tried that, but
My problem: how do I deal with the returns entered into the editor gadget though.

Try typing, press return a few times, time some more and then try entering it on the 4th line or so.

If I'm at the screen when a question gets posted, I don't lose too many! Some, but not many.

A scintilla gadget like the current PB editor uses will have its own messages you can send, but afaik it's a subclassed richedit control, so the normal messages should work too. I'm not too up on scintilla atm. It's on the todo list for someday as it looks quite interesting.

Like that code that freak posted, but it doesn't work with editor gadgets with multiple lines, I can't figure out how to edit it to do so.

netmaestro · Post by **netmaestro** » Sun Dec 09, 2007 11:44 pm

Sorry, I don't understand the problem. The same method works here to insert text on one of the empty lines after pressing return a few times.

Code: Select all

Heres the code:

; PureBasic Visual Designer v3.70a Beta


;- Window Constants
;
#Window_0 = 0

;- Gadget Constants
;
#Gadget_1 = 0
#original = 1
#start = 2


Procedure Open_Window_0()
  If OpenWindow(#Window_0, 402, 160, 293, 79, "test", #PB_Window_SystemMenu | #PB_Window_SizeGadget | #PB_Window_TitleBar)
    If CreateGadgetList(WindowID(#Window_0))
      TextGadget(#Gadget_1, 10, 10, 100, 30, "Enter String and select a piece:")
      EditorGadget(#original, 110, 10, 170, 133)
      ButtonGadget(#start, 10, 40, 70, 20, "make bold")
     
    EndIf
  EndIf
EndProcedure


Open_Window_0()

Repeat
  Event = WaitWindowEvent()
 
  If event = #PB_Event_Gadget And EventGadget() = #start
 
    original.s = GetGadgetText(#original) ; get strings from Gadget
    new.s = ""
   
    ; get selected position from #original Gadget
    SendMessage_(GadgetID(#original), #EM_GETSEL, @startpos.l, @endpos.l)
   
    new = Left(original, startpos)  ; unselected part on the left
    new + "<B>"    ; bold mark
    new + Mid(original, startpos+1, endpos-startpos) ; marked text
    new + "</B>"   ; unbold mark
    new + Right(original, Len(original)-endpos) ; unselected part on the right
   
    SetGadgetText(#original, new) ; set new text


    ; set selection again (3 characters right of original position, because we
    ; added the <b>
    SendMessage_(GadgetID(#original), #EM_SETSEL, startpos+3, endpos+3)
    setActiveGadget(#original)  ; activate Gadget again
 
 
  EndIf
 
Until Event = #PB_Event_CloseWindow
End

Try typing this in the box:

fdsfdsfjkdjsla

fjdsklfjdsl

dsada

And then put your cursor between s and a on the last line
and try entering the bold stuff
doesn't work right here...

I get:

jkjkl

jkl
<B></B>

hjk

I'm not sure what you're after, but try this :

Code: Select all


; PureBasic Visual Designer v3.70a Beta 


;- Window Constants 
; 
#Window_0 = 0 

;- Gadget Constants 
; 
#Gadget_1 = 0 
#original = 1 
#start = 2 


Procedure Open_Window_0() 
  If OpenWindow(#Window_0, 402, 160, 293, 79, "test", #PB_Window_SystemMenu | #PB_Window_SizeGadget | #PB_Window_TitleBar) 
    If CreateGadgetList(WindowID(#Window_0)) 
      TextGadget(#Gadget_1, 10, 10, 100, 30, "Enter String and select a piece:") 
      EditorGadget(#original, 110, 10, 170, 133) 
      ButtonGadget(#start, 10, 40, 70, 20, "make bold") 
      
    EndIf 
  EndIf 
EndProcedure 


Open_Window_0() 

Repeat 
  Event = WaitWindowEvent() 
  
  If event = #PB_Event_Gadget And EventGadget() = #start 
  
    a$=""
    SendMessage_(GadgetID(#original), #EM_GETSEL, @startpos.l, @endpos.l) 
    If endpos > startpos
      a$=Space(endpos-startpos+1)
      SendMessage_(GadgetID(#original), #EM_GETSELTEXT, 0, @a$)
    EndIf
    a$ = "<B>"+a$+"</B>"
    SendMessage_(GadgetID(#original), #EM_REPLACESEL, #True, @a$)
    SetActiveGadget(#original)  ; activate Gadget again 
  EndIf 
  
Until Event = #PB_Event_CloseWindow 
End

Try this code selecting a position with the mouse and pasting.

Code: Select all

OpenWindow(0,0,0,320,240,"",$CA0001)
CreateGadgetList(WindowID(0))
EditorGadget(0,0,0,320,200)
ButtonGadget(1,60,210,220,20,"use mouse to select a place and press this")
SetGadgetText(0, "The rain in Spain falls mainly on the plain."+Chr(10)+"The rain in France falls mainly on the plain.")

Repeat
  ev = WaitWindowEvent()
  Select ev
    Case #PB_Event_Gadget
      
 
    SendMessage_(GadgetID(0), #EM_GETSEL, @startpos.l, @endpos.l)
     
            
      Select EventGadget()
        Case 1
        	a$ = " [I put this here] "
          SetActiveGadget(0)
          SendMessage_(GadgetID(0), #EM_REPLACESEL, #True, @a$)         
      EndSelect
  EndSelect
Until ev = #WM_CLOSE

I still would like to know if it's possible to send code from an external app to the editor if it can be done?

Matt · Post by **Matt** » Mon Dec 10, 2007 2:24 am

Thank you srod and yrreti they both worked perfect.

srod, How do you not know what I was after?

I was trying to enter text at the location of the cursor in a editor gadget. The code freak posted would not work with multi-line text, the string to be added at the cursor's position was not added there correctly.

Matt

Question:
SendMessage_(GadgetID(0), #EM_GETSEL, @startpos.l, @endpos.l)
what is that line doing in yrreti's code? I suppose nothing?

yrreti · Post by **yrreti** » Mon Dec 10, 2007 2:59 am

Your right, that line is not needed. It was just some code
from another project that I didn't remove and wasn't sure about.
