Lister changes keyboard layout on specific RTF

[MVV]

Problem was posted on Rusian board, I removed extra instructions from RTF file and get this:

Code: Select all

{\rtf1

\plain\ltrch

test

}

Save this file as RTF and view in Lister. For me in TC 7.04a, 7.50a, 7.55b1 keyboard layout changes to Russian when I press F3 on this file.

If I remove \plain or \ltrch, layout preserves.

Is it possible to preserve keyboard layout in all cases?

Strange, from what language does it change to Russian? I have the Russian locale installed too (XP Pro), and it doesn't switch from German to Russian.

As i see it, this seems to be caused by the Richedit control used by TC (part of Windows itself). I cannot find anything in the Richedit documentation which allows to turn it off. Any ideas?

Layout switches from EN to RU.

I have no ideas, I even didn't see this until it was reported as 'old bug'.

BTW, when I open file in WordPad, layout doesn't change from EN to RU.


Added: on Russian board one user said that he has EN, BE, RU and DE (last installed for tests), and during opening this file layout always switches from EN or DE to BE or RU.

Maybe it needs russian codepage installed in Windows to reproduce bug?

I confirm, it switches from EN to SK (Slovak) here. No Russian anything installed here.

BTW if system codepage changed from Russign to English, situation reverses - layout is switches from RU and BE to DE etc...

I can confirm too, it switches from AR (Arabic) to EN

This definitely caused by the RichEdit control not TC.

when I open file in WordPad, layout doesn't change from EN to RU.

In WordPad (for XP) if you pressed <Home> or <End> the keyboard layout will be switched, so maybe TC send one of these keys to the RichEdit control after loading the file and that what causing the keyboard layout switch.

Anyway I don't see any problem as RichEdit control switch the keyboard layout according to the codepage of the character under the cursor, for example if you press F3 on Register.rtf in TC folder, your keyboard will switch from RU to EN.

I found a flag for RichEdit control that allows to switch or not to switch layout!

Code: Select all

#define IMF_AUTOKEYBOARD		0x0001

Language flags for RichEdit may be received and changed using SendMessage function:

Code: Select all

int flags=SendMessage(hEdit, EM_GETLANGOPTIONS, 0, 0);
SendMessage(hEdit, EM_SETLANGOPTIONS, 0,  flags);

And for Lister's TRichEdit this flag is set by default (flags=0x83), but when I've removed it (set flags to 0x82), layout didn't switch anymore! =)

So simple solution is to remove flag before loading RTF document:

Code: Select all

SendMessage(hEdit, EM_SETLANGOPTIONS, 0,  SendMessage(hEdit, EM_GETLANGOPTIONS, 0,  0)&~IMF_AUTOKEYBOARD);

Nice, thanks for finding that! It seems to work when setting it AFTER loading the actual file, because the loading seems to change these flags depending on the file contents...

If I set this flag to Lister's TRichEdit and load new file using File\Open then, all works fine - so I think loading doesn't change flags. But you may always try and get see if it works as should.

Confirm that the problem is fixed in 7.55pβ2.

[ts4242]

Fixed in 7.55 beta 2.
