Variables windows during debug [message #6902]

During debug you see variables in the bottom of the screen.

What I am suggesting is to:

1/ sort them, and sort their inner variables too (also during exploring).

2/ In Auto's window: Show the result of the last completed function. And if for example it's code like:

int func(int i) { return i*2; }
=>
i = 10;
func( func( func(i) ) );

Then it should show:

func returns         20
func returns         40
func returns         80
i                    10

So basically it's like: show return of each function + the variables used in those function calls...

This behaviour reflects the one of Visual Studio IDE.

Oh, just seen this one:

a call trace would be nice!

It is there - the field that displays current function has drop-down button.

Well, unfortunately, TheIDE's option there are somewhat limited by the library MS provides to retrieve the debug info from executables and also by documentation provided for that library... Smile

In reality, debugger is useful, but very often U++ LOG is better tool to for debugging. For GUI code, it is often the only option.

You can still use debugger but your app window must be open on second screen...

Well, that solves one problem.

But another one is that often some place in the code has to be performed 1000 times before something interesting happens. In that case, LOGs and Find (in the LOG file) are best option.

Yet another, more or less C++ problem is that debuggers are good for dumping simple values. But when dealing with complex C++ structures, it is often difficult.
