Do you have GTK_IM_MODULE set to scim-bridge? See issue 0015185 for details. |
|
|
I dont have scim-bridge. I use only scim-gtk, scim, scim-pinyin, scim-libs, scim-tables. Usually enviroment: XMODIFIERS=@im=SCIM GTK_IM_MODULE=scim QT_IM_MODULE=scim however I set bash-4.2$ export GTK_IM_MODULE= bash-4.2$ export QT_IM_MODULE= bash-4.2$ export XMODIFIERS= In that case everything is OK (but I cant input chines characters). The situation is not normal. |
|
|
What happens with "normal" gtk applications when GTK_IM_MODULE is enabled ? GtkEntry (TEdit) should be handled by gtk when inputting keys, so I'm wondering how LCL can repeat chars in that case . |
|
|
Others GTK2 GTK3 application work fine, and also GTK2-Perl, GTK2-Python apps (system-config-user for example). Trouble only with LCL-apps (doublecmd http://doublecmd.sourceforge.net/ for example). I use Fedora 17 x86 and Archlinux x86_64 - the same situation |
|
|
I comment call CheckDeadKey in function HandleGTKKeyUpDown gtk2proc.pp:2247 rebuild LCL - all work fine. Latin chars not duplicate and input chines characters with scim also work. GTK_IM_MODULE=scim |
|
|
hm..problem is that I cannot reproduce it with any input method (scim, scim-bridge, xim, iBus, simple). Please try next: make CheckDeadKey function function CheckDeadKey: Boolean; begin Result := False; ...current code.... change gtk_im_context_filter_keypress (im_context, AEvent); to: Result := gtk_im_context_filter_keypress (im_context, AEvent); end; at the place where CheckDeadKey is called say: Result := CheckDeadKey; if that doesn't work correct then try if CheckDeadKey then exit(True); |
|
|
with line if CheckDeadKey then exit(True); work fine ! latin, russian (keyboard), chines (scim) characters input is OK I try do similar modification, but with if CheckDeadKey then exit; that did not work; |
|
|
But with CheckDeadKey then exit(True) does not work here (with simple input). So, we must find the way to find out what im_context is used (it does not have any function which returns im name). |
|
|
Please test and close if ok. |
