Good evening, Ruurd.
I wonder if you could help out a Windows novice --- me?
My question concerns the way that Windows treats LyX --- as
a Windows GUI app or as a console one. At the moment, Windows
believes that LyX is a console app because it has a "main"
function rather than a "WinMain".
You've added code in os_win32.C's init function to close
down the console window that Windows helpfully displays
for us:
void os::init(int /* argc */, char * argv[])
{
#ifdef _WIN32
// Close the console when run (probably)
// not run from command prompt
char WindowTitle[1024];
HWND hwndFound;
GetConsoleTitle(WindowTitle,1024);
if ((strcmp(WindowTitle, argv[0]) == 0) ||
(strcmp(WindowTitle,"LyX") == 0)) {
// format a "unique" newWindowTitle
wsprintf(WindowTitle,"%d/%d",
GetTickCount(),
GetCurrentProcessId());
// change current window title
SetConsoleTitle(WindowTitle);
// ensure window title has been updated
Sleep(40);
// look for newWindowTitle
hwndFound=FindWindow(NULL, WindowTitle);
// If found, hide it
if ( hwndFound != NULL)
ShowWindow( hwndFound, SW_HIDE);
}
#endif
}
Would it not be more elegant to tell Windows that LyX
is actually a GUI-based app by giving it a WinMain?
The code below compiles fine for me with
$ g++ -mwindows -o trial trial.C
#if defined (_WIN32)
# define WIN32_LEAN_AND_MEAN
# include <stdlib.h> // for __argc, __argv
# include <windows.h> // for WinMain
#endif
#if defined (_WIN32)
int mymain(int argc, char * argv[])
#else
int main(int argc, char * argv[])
#endif
{
// LyX's code, unchanged, goes here.
Sleep(5000);
return 0;
}
// This will require the "-mwindows" flag when linking with
// gcc under MinGW.
// For MSVC, use "/subsystem:windows".
#if defined (_WIN32)
int WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
{
std::cout << "WinMain" << std::endl;
return mymain(__argc, __argv);
}
#endif
Regards,
Angus
