Qt general issue accessing a member of another class

[stuyfozz]

Hi,
I'm trying to access a member of a different class i.e. (i have took out all other code due to it being unrelated to my issue)

header1.h

@class MainWindow : public QMainWindow
{
public:
MainWindow();

public slots:
int open();
};
@
header2.h

@class SaveWindow : public QTextEdit
{
public:
SaveWindow();

public slots:
int save();
};
@
mainWindow.cpp

@#include "header1.h"
#include "header2.h"

int MainWindow::open()
{
BLAAA...
return save();
^^^^^^^^^^^^^^^wont let me access save, due to being MainWindow::open and save is not a member of that class! Tried creating an object and trying to access through that but no joy!
}

int SaveWindow::save()
{
BLAAA...
}
@
There is probably a simple solution.

doing....
@
SaveWindow sw;
return sw.save();
@
also gives me errors.
Thanks for any help :)

Edit: added some @ tags to your post to format your code; Andre

Please put your code in @ @ (without ) block.

This should work.
@
SaveWindow sw;
return sw.save();
@

But this code doesn't work:
@
int MainWindow::open()
{
BLAAA…
return save();
}
@
because MainWindow hasn't a save method.

Hi,
I'm confused, trying to access a member of a different class i.e.

header1.h

@class MainWindow : public QMainWindow
{
public:
MainWindow();

public slots:
int Open();

header2.h

@class SaveWindow : public QTextEdit
{
public:
SaveWindow();

public slots:
int Save();
};@

mainWindow.cpp

@#include "header1.h"
#include "header2.h"

int MainWindow::Open()
{
BLAAA...
return Save();

Sorry I'm new to Qt and posting

Read about some course or book about C++ because you issue is with language, not Qt. If you will had a basic skills with C++ then would be a sense to help you with your code. I think that now you are typing code in blind without understanding.

What should work is when you create a variable of the SaveWindow class and call that function.
@
int MainWindow::Open(void)
{
BLAA...
SaveWindow saveThing;
return saveThing.save();
@
if that works for you. The saveWindow will be destroyed when the open function quits, so don't worry about that.

Posting some code that will likely work is good, but in this case I think I agree more with Hostel since you really need to get your basic "Object Oriented" concepts clear. Otherwise its going to be too frustrated to do anything :)

So I hope that stuyfozz didn't totally got scare off and is busy reading some basic Object Oriented and C++ tutorials :)
