How to prevent screen to dim

I'm writing an Application which needs to disable the screen dimming. How can I do that in C/C++?

Re: How to prevent screen to dim

Is this also possible in Qt? Cause I didn't have a screen-object.

Re: How to prevent screen to dim

See if you can do this:

WId winId = window.winId();
if (winId)
{
int zorder = layer;
screen_set_window_property_iv(screen_window_t(winId), SCREEN_PROPERTY_ZORDER, &zorder);
}

Make sure "window" is a top level QWidget. From the code in the bb plugin, this its winId should be the native handle.

Re: How to prevent screen to dim

Thank you very much. It's working!!

 

I used the QMainWindow of my App.

 

WId winId = this->mainWindow->winId();
if( winId != NULL )
{
  int idleMode = SCREEN_IDLE_MODE_KEEP_AWAKE;
  screen_set_window_property_iv( screen_window_t(winId), SCREEN_PROPERTY_IDLE_MODE, &idleMode);
}
