New issue 12 by stephen....@gmail.com: Mapped CTRL-C doesn't work in gvim
due to focus out/in events confusing ctrl_c_interrupts.
http://code.google.com/p/vim/issues/detail?id=12
What steps will reproduce the problem?
1. Run Gnome 2 desktop environment.
2. In Gnome, System menu -> Preferences -> Assistive Technologies, pops up
a window, click "Mouse Accessibility" button, pops up a window,
click "General" tab, enable "Show position of pointer when the Control key
is pressed".
3. In .vimrc, map C-C to something (e.g. use mswin.vim to map C-C to copy)
4. Run gvim
5. Press C-C (e.g if in mswin mode, select some text (e.g. Shift-DownArrow
a couple of times then press Ctrl-C)
What is the expected output?
Selected text is copied. Selected text stays highlighted.
What do you see instead?
No text is copied (C-V won't paste it). Selected text gets unhighlighted;
visual mode is exited.
What version of the product are you using? On what operating system?
64-bit Ubuntu Natty, Ubuntu-packaged gvim (vim 7.3.35). Also happens with
7.3.219 built from latest Hg source.
Please provide any additional information below.
This can be fixed (or perhaps just hacked around) by editing gui_gtk_x11.c
near the end of function key_press_event() from:
if (len == 1 && ((string[0] == Ctrl_C && ctrl_c_interrupts)
|| (string[0] == intr_char && intr_char != Ctrl_C)))
{
trash_input_buf();
got_int = TRUE;
}
to:
if (len == 1 && ((string[0] == Ctrl_C && ctrl_c_interrupts
&& !mapped_ctrl_c)
|| (string[0] == intr_char && intr_char != Ctrl_C)))
{
trash_input_buf();
got_int = TRUE;
}
But a better solution probably relies on correctly setting
ctrl_c_interrupts to WAR the issue described below.
Background:
If the Gnome option "show mouse pointer position" is not set,
ctrl_c_interrupts is false when the C-C keypress is received, and
everything works.
However, due to the extra keypress events processed when "show mouse
pointer position" is enabled, ctrl_c_interrupts gets set back to true, and
C-C triggers trash_input_buf() etc. The extra keypress events from the
Control key being pressed are injected from focus lost/gained events, which
IIRC get injected from gui.c function gui_focus_change().
