Window Blink/Flash

[VireX]

Well thats pretty obvious. #include <windows.h>, thats my only include, and it WOULD work if it was truly defined in winuser.h, and since it is a simple plain Win32 project, there is no mistake or mixup with Qt. It's definitely a problem with my windows.h or Dev-C++ in general. Either that or FLASHWINFO doesn't exist.

Qt 4.3 is not out yet. The only download is qt-win-opensrc... it's not the mingw version so I cannot get it to work.

Have you included the windows api src in your mingw install?
I just downloaded it from http://prdownloads.sf.net/mingw/w32a...ar.gz?download

I can find in there both windows.h and winuser.h and FlashWindowEx is defined in winuser.h.

Maybe your mingw install is not OK.

Edit:
Dev-c++ should have an include path option. Make sure the path for the windows api is added there.

Regards.

My winuser.h has FLASHWINFO defined, and it is included.
If it wasn't included I would have more errors than just FLASHWINFO.

Compiler errors:

Oh btw you guys should rly consider removing the line number from geshi filter, annoying...

But this error, look how ridiculous this is:
#include <winuser.h>
MOUSEMOVEPOINT mmp;

[VireX]

I got it to work when using:
#define _WIN32_WINNT 0x0501
#define WINVER 0x0501

[marcel]

Nice... I wasn't sure where the error came from...

[VireX]

Tried to develop some sort of efficient way to do this:
Because FLASHWINFO only works if WINNT is greater than 0x0500! Meaning its an XP/2k-Only feature... Therefore, I had to get the version info. Which works fine, but FLASHWINFO still says "undeclared first use this function". Quite odd... any other ideas?

#include <windows.h>
int GetWinXP(){
  OSVERSIONINFO osVer;
  int xp = 0;
  osVer.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);
  if(GetVersionEx(&osVer) != 0){
     if(osVer.dwPlatformId == VER_PLATFORM_WIN32_NT){
       xp = 1;
     }
  }  
  return xp;
}
void CLobby::SendMsg(){ // A SLOT()
  QString qsMsg;
  // do some Qt Stuff
       MsgSend->clear();
       if(GetWinXP() == 1){
         #undef _WIN32_WINNT
         #undef WINVER
         #define _WIN32_WINNT 0x0501

         FLASHWINFO finfo;
         finfo.cbSize = sizeof( FLASHWINFO );
         finfo.hwnd = this->winId();
         finfo.uCount = 20;         // Flash 20 times
         finfo.dwTimeout = 400; // Duration in milliseconds between flashes
         finfo.dwFlags = 1|2|12; //Flash only taskbar button

Maybe because Windows.h includes winuser.h before you def and undef the windows versions.

What version of windows do you have?

Regards.

[VireX]

WinXP of course the best windows.

[marcel]

Perhaps this is a bug in mingw?
What if you move the defines to the top? Before including windows.h...

Should work.

Qt 4.3 is not out yet

Qt 4.3 is out but only as a beta...

Alternatively you can always use a combination of QWidget::show() QWidget::raise() and QWidget::setFocus() which on most platform will cause a blinking when the window can not be actually shown, raised and focused...
