How to set a unicode font(Malayalam) font in RichEdit

Recommended Posts

Hi all,

I am up to change the font of a rich edit control. I need to set an unicode font(Malayalam). But the code doesn't working.

see this.

Global $EditMallu = _GUICtrlRichEdit_Create ($FormM2M,"", 520, 37, 489, 417)
_GUICtrlRichEdit_SetText ($EditMallu, "]co£Ww")
_GUICtrlRichEdit_SetFont ($EditMallu, 14, "MLTTRevathi")
;GUICtrlSetColor($EditMallu, 0x0000FF)
_GUICtrlRichEdit_SetEventMask($EditMallu, "EditMalluChange")

Original name of that font is this = "ML-TTRevathi". What is wrong with it ?

Edit - I can't change the font color too.

When you change the font, what isn't working? Also, have you set the LCID parameter to Malayalam? First number is hex, second is Dec.

@BrewManNH See the code in my first post. In line number 2, you can see a strange text in red color. That text is in malayalam. Why it is showing like that because the font in the browser is English font. But i have programatically changed my RTB font to a malayalam font. And then i can;t see the right malayalam letters in RTB. I can only see the text as same as shown in this browser.

Try using the font name MLW-TTREVATHI, the font packs I've found that list it as ML-TTREVATHI actually have the font name with the W in it.

@BrewManNH , No way. Interesting thing to notice. I have another controls in my form. Say a button. I set my button's font to "ML-TTRevathy". It is working. It shows the font properly. So only RichEdit control has the problem. 

 

Edit - Tested with LCID. But no way. 

Second Edit - I have thested it with _GUICtrlRichEdit_GetFont  function. It says the font is "MS Shell Dlg". Why ?

btw.

_GUICtrlRichEdit_SetEventMask($EditMallu, "EditMalluChange")

You are using this function in a wrong way.

The second parameter must bu number.
If you try to add

_GUICtrlRichEdit_SetEventMask($EditMallu, "EditMalluChange")
If @error Then MsgBox(0, '@error', @error)

Then I'm sure you get 102 in MsgBox.

 

 

EDIT:

Try also:

Global $EditMallu = _GUICtrlRichEdit_Create($FormM2M,"", 520, 37, 489, 417)

_GUICtrlRichEdit_SetFont($EditMallu, 14, "MLTTRevathi")
If @error Then MsgBox(0, '_GUICtrlRichEdit_SetFont @error', @error)
_GUICtrlRichEdit_SetText($EditMallu, "]co£Ww")
If @error Then MsgBox(0, '_GUICtrlRichEdit_SetText @error', @error)

;GUICtrlSetColor($EditMallu, 0x0000FF)
_GUICtrlRichEdit_SetEventMask($EditMallu, "EditMalluChange")
If @error Then MsgBox(0, '_GUICtrlRichEdit_SetEventMask @error', @error)

 

Did you get additional @error messages ?

@mLipok , No, i don't get any error messages. And you are right. the event mask function is wrong. But That is not my issue.

      Hey there!
      I'm gonna try to get access to an RichEdit Control in PSPad with Autoit which is scripted with Delphi. I wrote the commands out ouf the RichEdit.au3 UDF to can change them, because it always fails or crashs, when i call it. I Just want to set the Textcolor for the RichEdit.
      It seems to be a Problem with $EM_SETCHARFORMAT... (maybe protected?) I can use e.g. $EM_SETBKGNDCOLOR or other messages with no error. Sadly it doesn't exist a message constant to just set the textcolor... This is what i already tried:
      use $EM_GETCHARFORMAT but it crashs/doesn't work too. I saw the riched20.dll is linked to GDI+ but i couldn't make something work with it... (GetDc and so on but maybe there is another way?) Tried to set some other style on it (setWindowLong) I read the MSDN about $EM_SETCHARFORMAT up and down, but i can't find any other solution.
      The RichEdit should be version 2 ( error message point to riched20.dll )
       
      Here is the PSPad that will be required for testing:

      This UDF allows to create formatted label using pseudo element RichLabel (RichEdit actually). Formating is set by using special modificator similar to <font> tag in Html.
      Notes: This UDF is a transformation-continuation of related UDF


      Example:

      I'm trying to create a simple clock widget that automatically scales the text to the size of the window. I came up with the following method, but it doesn't work as well as I'd like. It especially has trouble scaling to the width of the window for some reason (in the example, try resizing the window to be narrow and tall).
      Does anyone have a better method?

      I am trying to print using a small font, but no mater how I try it, the printed font remains unchanged.
      I have created a sample script that sets the font to 8.
