oBtn:ToolTip - UTF8 encoding fails [Unsolved]

[frose]

UTF8 encoding fails - switches to Ansi - in BUTTON/TButton() and TBtnBmp() ToolTips!

Sample:

Code: Select all  Expand view

REQUEST HB_CODEPAGE_UTF8

For TButtonBmp() encoding is ok:

Regardss, saludos.

thank you for the tip but I can't switch code pages for the following reason:

My application is a translation memory system (TMS) and should support as many languages as possible.
It should therefore be able to process, display and edit as many Unicode characters as possible at the same time, I think UTF8 is the best choice for this.

For example, there is a dialog to display all translations of a term, e.g. 'atmosphere':

[nageswaragunupudi]

We will look into the issue of tooltips.

Display of Utf8 depends purely on FWH
This has nothing to do with HB_CDPSELECT( "UTF8" ). This setting is useful only for Harbour file and directory functions when these names are in UTF8, applicable mostly for East Asian Language applications.
In my view, keep HB_CDPSELECT( <yourcontrycdp> )

Does this mean that we can only use chars provided by FWH, even if we use a different font?

I tried it with the font 'unscii' from http://viznut.fi/unscii/, unfortunately without success!

Good to know.

...UTF8, applicable mostly for East Asian Language applications.

But there are many multibyte characters that occur in other non-East Asian languages and are not included in ANSI! E. g. Characters specific to Central and Eastern European languages (e.g., Czech, Polish, Hungarian) like Č, Ć, Đ, Ł, Ń, Ő, Ű, Ś, Š, Ž, etc., available in Latin Extended-A (ISO 8859-2).

In my view, keep HB_CDPSELECT( <yourcontrycdp> )

Yes, if you only want to process, display and edit the characters that use the same character set (code page). This is not the case in my environment!

UTF8 encoding fails - switches to Ansi - in BUTTON/TButton() and TBtnBmp() ToolTips!

Can you please make this modification in "window.prg" and try?

Locate these lines in the METHOD ShowToolTip() of Window.prg:

Code: Select all  Expand view

      if IsWindowUnicode( ::hWnd )
//         cText = HB_UTF8LEFT( cText, 98 )
         hWnd = CreateToolTipWNew( ::hWnd, cText, IfNil( ::lBalloon, lTTBalloon ), cTitle, hIcon, nClrFore, nClrBack, nWidth, nDelayTime, nDelayType )
      else
//         cText = Left( cText, 99 )
         hWnd = CreateToolTipANew( ::hWnd, cText, IfNil( ::lBalloon, lTTBalloon ), cTitle, hIcon, nClrFore, nClrBack, nWidth, nDelayTime, nDelayType )
      endif

Replace ALL these lines with this one line:

Code: Select all  Expand view

hWnd = CreateToolTipWNew( ::hWnd, cText, IfNil( ::lBalloon, lTTBalloon ), cTitle, hIcon, nClrFore, nClrBack, nWidth, nDelayTime, nDelayType )

Please try after this change.

chars provided by FWH?

FWH does NOT provide any chars. FWH does not have any chars of its own.

FWH displays any text using Windows APIs

Any utf8 encoded text of any language in the World can be displayed using any Windows font.

Ansi encoded text containing some accented characters of WU languages can be displayed only with a font created using the corresponding Charset. But most FWH functions display them by converting them to utf8 encoding. (we will fix where there are some inadequacies still). Setting HB_CDPSELECT("UTF8") has nothing to do with this process.

[frose]

Any utf8 encoded text of any language in the World can be displayed using any Windows font.

This reassures me

Please try after this change.

Thanks
Wondering how do you know my mother tongue?
India has 21 Unicode languages.

Wow, I can't believe. We are downright ridiculous with our 4 multibytes.

I've asked ChatGPT
The answer was:

... In Hyderabad, India, the main languages spoken are Telugu, Urdu and English. Telugu is the predominant language in Hyderabad and Telangana, while Urdu is used as the second official language...
