how to disable accelerate

Rate this Message:
Hi,all
I read some source code of Scintilla, and find there is a keymap struct defines some but not all accelerate in keymap.cxx, I want to disable some accelerate not in keymap.cxx defined such as Ctrl+Shift+2/Ctrl+Shift+6 etc. SCI_ASSIGNCMDKEY seems not work, what can I do then? Thanks.

If its not in the keymap then its probably being processed by your application. Another possibility is that you are using a keyboard layout that has mapped these keys to something recognised by the keymap. This could occur if you are using a non-English keyboard layout or a machine (such as a laptop) that has moved functions around.

Hi, Neil Hodgson
I read the Scintilla source code, it's not in the keymap, and I'm sure my application do not process these keys. I create simple demos to show Scintilla control, and do nothing else, then the accelerates exist. I have tested on my IBM T43 laptop (Windows XP Pro Sp2 English edition with Chinese language patch) and several Lenovo machines (Windows XP Pro SP2 Chinese edition) with standard 104-keys keyboard, this bug exists. Also, I have tested with MFC and WTL framework on VC 2003, and VCL framework on Borland C++ Builder 6.0, this bug exists. These accelerates do display some strange characters, or move the caret/do backspace etc. ======= 2007-08-01 05:37:02 you said：======= >YangFan: > >> I read some source code of Scintilla, and find there >> is a keymap struct defines some but not all accelerate in >> keymap.cxx, I want to disable some accelerate not in >> keymap.cxx defined such as Ctrl+Shift+2/Ctrl+Shift+6 etc. >> SCI_ASSIGNCMDKEY seems not work, what can I do then? > > If its not in the keymap then its probably being processed by your >application.

Best thing to do now is to run the code under a debugger with breakpoints in the WM_SYSKEYDOWN / WM_KEYDOWN handling to see what is happening.

Hi, Neil Hodgson
I set breakpoint in ScintillaWin.WndProc in the WM_SYSKEYDOWN/WM_KEYDOWN handler, found that every strange accelerate is processed by ::DefWindowProc, but then some one (I don't know who -_-b ) sends a WM_CHAR message to the window. In the WM_CHAR handler, there's a function call iscntrl() to judge if the integer represents a control character, but another more condition lastKeyDownConsumed. I could not understand the usage of variable lastKeyDownConsumed, may I change || to && as shown below ? case WM_CHAR: if (!iscntrl(wParam&0xff) && !lastKeyDownConsumed) { ~~~~ if (IsUnicodeMode()) { // For a wide character version of the window: //char utfval[4]; //wchar_t wcs[2] = {wParam, 0}; //unsigned int len = UTF8Length(wcs, 1); //UTF8FromUTF16(wcs, 1, utfval, len); //AddCharUTF(utfval, len); AddCharBytes('\0', LOBYTE(wParam)); } else { AddChar(LOBYTE(wParam)); } } return 0; ====== 2007-08-01 08:37:39 you said：======= >YangFan: > >> I read the Scintilla source code, it's not in the keymap, >> and I'm sure my application do not process these keys.

They are being sent by Windows. This is normal entry of control characters, not accelerators. Is your problem the appearance of [NUL], [BEL], ... when users type these characters? That is normal entry and display - not caused by accelerators. If you want to disable control character entry, process them in your application or assign them to null accelerators.

Hi, Neil Hodgson
That's my problem. I tested on a simple SDK written program, Windows sends WM_CHARs. But then another problem, I don't know how many control characters are binded to keys, to which keys. Users would feel confused when they press Ctrl+Shift+2 [NUL] appears or Ctrl+Shift+6 [RS] appears etc. ======= 2007-08-02 06:02:17 you said：======= >YangFan: > >> ... in the WM_SYSKEYDOWN/WM_KEYDOWN handler, found that >> every strange accelerate is processed by ::DefWindowProc, but then >> some one (I don't know who -_-b ) sends a WM_CHAR message >> to the window. > > They are being sent by Windows.

Hi, Neil Hodgson
Many thanks, I searched the web, and found a keyboard control character table at http://publib.boulder.ibm.com/infocenter/iseries/v5r4/index.jsp?topic=/rzaiw/rzaiwkeyboard.htm Hope to some useful for somebody. ======= 2007-08-02 06:02:17 you said：======= >YangFan: > >> ... in the WM_SYSKEYDOWN/WM_KEYDOWN handler, found that >> every strange accelerate is processed by ::DefWindowProc, but then >> some one (I don't know who -_-b ) sends a WM_CHAR message >> to the window. > > They are being sent by Windows.
