Autoselecting text in Richedit control when focussed by Tab Key

[Fenzik]

Hello all,

i have following question.

Is it possible to prevent the Richedit control from autoselecting text when control is focussed by Tab key?

You can see this behaviour in this modified example from Help file.

When you press the Tab Key and cycle through the elements, when Richedit is focussed, the text is every time selected.

Is there some way to prevent this, so the selection remains untouched when i focus the Richedit?

Thank you.

Func Example()
        Local $hGui, $hRichEdit, $iMsg

                                _GUICtrlRichEdit_Destroy($hRichEdit) ; needed unless script crashes

Hi Fenzik,

Just add style 0x00008000 in your BitOr() when creating the richedit control.
Now everybody's searching what style is it

Hello pixelsearch,

it works like a magic..

I do'nt why and how, but it works.

Can you describe the style, hope not only for me?

Thank you so much for the easy and effective solution!

Sure !
It corresponds to style $ES_SAVESEL (not sure it's in AutoIt help file but I may be wrong)
Infos on MSDN page :

ES_SAVESEL : Preserves the selection when the control loses the focus.
By default, the entire contents of the control are selected when it regains the focus.

I indicated its "not really useful" value 0x00008000 just for fun, as found in the 2nd spoiler in this post.

Thank you.

So i think that it's useful for example for accessibility reasons, because when you have for example some read only Richedit with some text, you don't want to have it selectet when you use the keyboard to navigate the focus.

The second relatively related sideeffect is the difference between _GUICtrlRichEdit_SetText and _GUICtrlRichEdit_StreamFromVar functions, where _GUICtrlRichEdit_StreamFromVar function put the cursor to the last character of the text and _GUICtrlRichEdit_SetText function puts it on the first character.

Thank you again!
