how to open several ui from a main menu

[Paulo G]

put in .h file inside the class definition
siguiente *prueba=NULL;

in mainWindows.h

error de compilation

@Paulo-G It would help if you would tell us what error you get...
And can you show the header file so we can see where you added that line?

mainwindow.h:30: error: 'siguiente' does not name a type
siguiente *vRoll=NULL;

@Paulo-G said in how to open several ui from a main menu:

mainwindow.h:30: error: 'siguiente' does not name a type

include the header file where siguiente is declared. Or if it is already the case is this siguiente in a namespace?
Maybe

Ui::siguiente vRoll = NULL;

?

En mainwindows.h
public:
Ui:: siguiente *vRoll=NULL;

En mainwindows.cpp

if (vRoll=NULL)
vRoll=new siguiente();
vRoll->show();

----error
cannnot convert 'siguiente*' to Ui::siguiente*'
class Ui::siguiente has no member name show

Hi
siguiente seems to be a dialog so not very likely its inside
UI::
You did have
#include "siguiente.h" in top of the mainwindow.h ?

[Paulo G]

I had already added headers

#include "siguiente.h"

@Paulo-G
If so - it should accept
siguiente *vRoll = NULL;
if it still complains, try
siguiente *vRoll;
( and set it to null in constructor)

@Paulo-G
I doubt that, in the screenshot you posted, the line after

#include "siguiente.h
is clearly
#include "ui_siguiente.h

that let's me to believe, that you placed #include "siguiente.h inside siguiente.h or siguiente.cpp
