Hi,
I am working on an extension for scite for windows
(working with scite 1.7.2).
I would like it to both filter the keys coming to
application (not just the regular characters) and
perform background processing.
The way that makes sense to me to do this is to create
a windows proc which replaces the default windows
procedure and calls it - a la the single thread
extension. I wasn't thinking of a timer since I want
to also do keystroke filtering.
My question is whether this seems like an approach
which could work with all the internals of scite
(which seem quite usual though I haven't looked in
every nook and cranny of its code).
Thanks in advance
LRESULT PASCAL PatternRepeaterExt::WndProc(HWND
tempHWND, UINT tempUMsg, WPARAM tempWParam,
LPARAM tempLParam) {
//We will soon go into this loop and never emerge
if (tempUMsg == STE_WM_DO_BACKGROUND_PROCESSING) {
while(true){
MSG msg;
while ( ::PeekMessage( &msg, NULL, 0, 0,
PM_NOREMOVE ) ){
if (!::GetMessage(&msg, NULL, NULL, NULL)){
::PostQuitMessage(0);
return 0;
}
//sniff through
if(msg.message == WM_NOTIFY){
mapIndexPtr->at()->OnTextModified(
(SCNotification *)&msg);
mapIndexPtr->at()->UpdateStates();
}
::TranslateMessage(&msg);
::DispatchMessage(&msg);
}
//Wait a bit
if( clock() < gLT + iNCR ){
continue;
} else {
gLT = clock();
}
//Do our idle processing
if(mapIndexPtr && mapIndexPtr->at()){
if(!mapIndexPtr->at()->IdleProcessing()){
::WaitMessage();
}
} else {
//Then let the system do its thing, hopefully
::WaitMessage();
}
}
}
WNDPROC lpPrevWndProc = reinterpret_cast<WNDPROC>(
GetWindowLongPtr(tempHWND, GWLP_USERDATA));
if (lpPrevWndProc){
return ::CallWindowProc(lpPrevWndProc, tempHWND,
tempUMsg, tempWParam, tempLParam);
}
return ::DefWindowProc(tempHWND, tempUMsg,
tempWParam, tempLParam);
}
And it would be created with the calls
hwndDispatcher = CreateWindow(
"STATIC",
"SciTE_PatternRepeaterExtension_Dispatcher",
0, 0, 0, 0, 0, 0, 0, GetModuleHandle(NULL), 0
);
LONG_PTR subclassedProc = ::SetWindowLongPtr(
hwndDispatcher, GWLP_WNDPROC,
reinterpret_cast<LONG_PTR>(WndProc)
);
SetWindowLongPtr(hwndDispatcher,
GWLP_USERDATA, subclassedProc);
SendMessage(hwndDispatcher,
STE_WM_DO_BACKGROUND_PROCESSING,0, 0);*/
