Scintilla Editor experiment

[kcvinu]

Hi all,

I have got a code snippet from Scintilla's website.  The code is for creating a scintilla control in visual basic. I have altered it and did some experiment with it in AutoIt. After some failed attempts, i got succeeded in creating a simple scintilla cotrol in my gui. That experiement raises a lot of questions in my mind. Some of them are i am asking.

1. So we are cretaing scintilla as a child window ?. I thought that it is a control. 

2. No.. not any more. This is my code. I am seeking guidance and advices to learn more about this. Thanks in advance.

#include <WindowsConstants.au3>
#include <GUIConstantsEx.au3>
#include <WinAPI.au3>
#include <SendMessage.au3>

Local $h__MainGUI = GUICreate("Window", 500, 400, -1, -1)
GUISetState()
Local $h__THisGUI = WinGetHandle($h__MainGUI)
Local Const $SCI_START = 2000
Local Const $SCI_ADDTEXT = $SCI_START + 1
Local Const $SCI_SETSELBACK = $SCI_START + 68

Local $h__sciDLL = _WinAPI_LoadLibrary("E:\2014 Softwares\KE editor\SciLexer.dll")
Local $h__sciWnd = _WinAPI_CreateWindowEx($WS_EX_CLIENTEDGE, "Scintilla", "TEST",BitOR($WS_CHILD, $WS_VISIBLE),0,0,480,380,$h__THisGUI,0)
_SendMessageA($h__sciWnd, $SCI_SETSELBACK, 1 )
_SendMessageA($h__sciWnd, $SCI_ADDTEXT, 16, "This is Vinod")

While 1
    $hMsg = GUIGetMsg()
    Switch $hMsg
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

Au3Info can tell you that.

 the dll internally first register an Scintilla class using RegisterClassExW then use RegisterClassExA to  create the window\control.

@Danyfirex Thanks. Let me check it with Au3Info.

[kcvinu]

Yes. And we can treat it as our own control in that GUI. 

Now, i am reading the documentation.

Yes Look:

#include <WindowsConstants.au3>
#include <GUIConstantsEx.au3>
#include <WinAPI.au3>
#include <SendMessage.au3>
Global Const $__EDITCONSTANT_WM_SETTEXT = 0x000C
Local $h__MainGUI = GUICreate("Window", 500, 400, -1, -1)
GUISetState()
Local $h__THisGUI = WinGetHandle($h__MainGUI)
Local Const $SCI_START = 2000
Local Const $SCI_ADDTEXT = $SCI_START + 1
Local Const $SCI_SETSELBACK = $SCI_START + 68

Local $h__sciDLL = _WinAPI_LoadLibrary("SciLexer.dll")
Local $h__sciWnd = _WinAPI_CreateWindowEx($WS_EX_CLIENTEDGE, "Scintilla", "TEST",BitOR($WS_CHILD, $WS_VISIBLE),0,0,480,380,$h__THisGUI,0)
_SendMessageA($h__sciWnd, $SCI_SETSELBACK, 1 )
_SendMessageA($h__sciWnd, $SCI_ADDTEXT, 16, "This is Vinod")

_GUICtrlEdit_SetText($h__sciWnd,"Hola Mundo. AutoIt Rocks")

While 1
    $hMsg = GUIGetMsg()
    Switch $hMsg
        Case $GUI_EVENT_CLOSE
            Exit

    EndSwitch
WEnd

Func _GUICtrlEdit_SetText($hWnd, $sText)
    If Not IsHWnd($hWnd) Then $hWnd = GUICtrlGetHandle($hWnd)

    _SendMessage($hWnd, $__EDITCONSTANT_WM_SETTEXT, 0, $sText, 0, "wparam", "str")
EndFunc   ;==>_GUICtrlEdit_SetText

Documentation says that to use WM_NOTIFY message to work with scinitlla control. They gave an example c++ code to do it. But i just check it with an ordianry WM_COMMAND function in GUIRegisterMsg. As if it s an edit control in my gui. It worked, but it gave output twice to me. I don't know why.

[kcvinu]

@Danyfirex Please tell me about the const $__EDITCONSTANT_WM_SETTEXT. help file says that it is "Msg to send to control (Number). And in the example they used $WM_SYSCOMMAND. I am confused a little.

It's just for send text to a control https://msdn.microsoft.com/en-us/library/windows/desktop/ms632644(v=vs.85).aspx

Pretty sure somebody else has create an editor in AutoIt using Scintilla and posted about it in the forum. Maybe look for that.

Also ISN AutoIt Studio is based on Scintilla.

Do you mean how to configure that tooltip in SciTE?

Jos

[Danyfirex]

No no. I mean what it use internally. maybe how to reproduce that using sendmessage. then I will look inside to check that message because I think It should be a predefined message.

[Jos]

SciTE will show the Calltips when you send IDM_SHOWCALLTIP to it.

Jos

[Danyfirex]

the one with scrollbar? 

Saludos.

[Jos]

That is the same message, but obviously there need to be multiple options in au3.api for it to trigger that version.

[Danyfirex]

I see. Thank you Jos.
