I use VC++ MFC 4.2.
I have a few MULTILINE CEdits.
If user press Enter key on one of the CEdit then it will act like Tab key
which is going to change focus to other CEdit.
If user press Ctrl + Enter, then it will act like Enter key in a notepad
which is going to a NEW line.
How to do that?
Why not use ES_WANTRETURN? Then pressing Enter starts a new line, tab works
like tab, and Ctrl+Tab moves to the next control.
I have tried this code but if I press Ctrl + Enter, it acts like Tab. I was
confused.
Thank you.
BOOL CEditEx::PreTranslateMessage(MSG* pMsg)
{
// TODO: ???????????????????????????????????
if( pMsg->message == WM_KEYDOWN ){
if( pMsg->wParam == 11 && pMsg->wParam == 13 )
How can it be two things at once? Also, it's better to use VK_xxx constants
or even C++ escape sequences, such as '\r'.
return CEdit::PreTranslateMessage(pMsg);
else if( pMsg->wParam == 13 ) //13: ENTER KEY
pMsg->wParam = 9; // 9: TAB KEY
}
return CEdit::PreTranslateMessage(pMsg);
}
If you really want to implement the behavior you described, this is how you
can check things in PreTranslateMessage:
if (pMsg->message == WM_KEYDOWN)
{
if (pMsg->wParam == VK_RETURN)
{
if (GetKeyState(VK_CONTROL) < 0)
... // Ctrl+Enter
else
... // Enter
}
}
If you really want to replace this message, you may run into trouble,
because the recipient can call GetKeyState himself. You may have to use
SetKeyboardState to work around that.
