As a clue: if you enter:

10<enter>

getline will eat up the <enter> (though the <enter> won't appear in userInput - it is discarded). What then will be the effect of the subsequent call to...

You don't appear to be initialising uimain anywhere.

That's actually not what is happening; add some strategic debugging statements to get a clearer view of what is going on, here :)

Pretty much the entirety of KDE (from toolkit - "Qt" - to practically all of its apps) are written in C++, as are popular apps such as Firefox, Chromium, Open/LibreOffice, Abiword etc. gcc was pure...

Unity is mostly C++:

First step: run it in gdb and find out what line it crashes on :)

class MyClass {
public:
MyClass(const int N_):N(N_), myMap(MapCompare(N)) {
myMap.clear();

};

private:
int N;

In your "for" loop, you only ever compare one pair of elements.

Edit:

Also, read this: you are disobeying the contract.

Please use code tags!

The error is in the line:



std::map<int*, int, MapCompare> myMap(MapCompare(N));


Google for "most vexing parse".

No problem :) clang's output is slightly better, but still doesn't quite get to the nub of the matter. Might file a bug report ...

"&AppendOneOfThese [3]" is a temporary, and temporaries cannot be bound to non-const references.

This works:




#include <iostream>
#include <cstring>
/*!

You aren't initialising your textEdit member variable declared in gui_output2.h (you initialise a local variable with that name in gui_output2::gui_output2()).

It's very similar, but not identical to Filelight:

I've added some obvious corrections, but a lot of the code is too bewildering to fix, in which case I've left comments - they're meant to be friendly criticism, so please don't take offense :) //...

Other way round: KDE + Qt have expended a lot of effort to make KDE apps fit in properly in GNOME (e.g. QGtkStyle; using GTK file dialogs in GNOME/ XFCE, etc). The other way round - GTK apps looking...

"partition" could be the one from the C++ Standard Library:

This works only by fluke; you're still dereferencing a pointer to an object whose lifespan has ended: you got lucky that this implementation of C++ doesn't bother to "destroy" unsigned ints declared...

I'm guessing C++ handles the "MyType var[3]" in the catch clause in the same way that it handles it in a parameter list - by treating it as MyType*. Coupled with this, from the spec:



So...

I just checked out the source for gtkmm and can confirm that Gtkmm::Button inherits from Gtkmm:Bin, as suggested here (inheriting from Gtkmm::Activatable is marked as TODO) - so based on this...

spjackson's suggestion compiles fine, here. Is the code in the OP copy-and-pasted? If so, you have a rogue "," before the closing bracket.

*coughs* ;)

C# has Qt bindings (though I don't know how well they work and whether they are still maintained), so it's not necessarily either-or.

Add "and they aren't given a parent", and that sounds like a good rule - I can't think of any exceptions offhand.

window isn't given a parent, so Qt doesn't delete it for you - therefore, it's safe to handle destruction yourself. May as well just allocate it on the stack :)
