fgets in Qt(Gui mode)

[summer_of_69]

It's a 18 years old legacy code written in "C" contains 2,86063 lines with fgets in more than 100 places.
I have already created GUI for that with all interface,if no other option I will have to go for this bull work.Before this I want to be 100% sure that there is no other way than to change the whole code and replace it with "QInputDialog/QFileDialog" etc...

i dont have exp in console apps... and your situation is unique...

if i were u then i would just search and replace the fgets as

search
fgets(char*,xx,xx,xx);
 replace with
myFgets(char*,xx,xx,xx);
 
its a very easy thing and u dont have to do anything if u use any text editor..
 
then make your function
myFgets(char* str,xx,xx,xx)
{
  QString file=QInputDialog/QFileDialog;
  str=(convert string char by char);
}

search
fgets(char*,xx,xx,xx);
 replace with
myFgets(char*,xx,xx,xx);

its a very easy thing and u dont have to do anything if u use any text editor..

then make your function
myFgets(char* str,xx,xx,xx)
{
  QString file=QInputDialog/QFileDialog;
  str=(convert string char by char);
}

Sorry I didn't explain the whole scenerio. My application has two modes "GUI" and "Console" ,user can opt for any using Config file(which I have yet to create). Application has to read that file and load the application accordingly(console/gui mode).

Now my problem is how can I do this? I don't want two different exe for console and GUI
That's why I am searching for some solution to control console using GUI so that only one exe is enough.
