Frames connection

[cuios]

I have created a form MainWindow - QMainWindow class and a Frame - QFrame class , after that in the mainwindow.ui.
I have added a button and created a new singnal clicked > openframe , after, in the mainwindow.h i have added public slots : void openframe() , after that in the mainwindow.cpp i have added:
#include "frame.h"

and

void MainWindow :: openframe()
{
Frame frame();
frame.exec();
}

but it is not working

please help me to connect these two frame with button click

[Ginsengelf]

void MainWindow :: openframe()
{
Frame frame();
frame.exec();
}

frame goes immediately out of scope after exec() returns, so if exec() does not block you'll probably see only a short flicker.

Try to create it on the heap with "new".

Try creating your frame in heap like this

MainWindow:MainWindow()
{
frame = new QFrame(this);
--------
}

btw, QFrame hasn't method exec() ;)

I have tried this

MainWindow *other = new MainWindow;
other->show();

but I do not want to duplicate the frame , all I want is to use one that was designed in Qt Creator GUI designer

thanks a lot

Hi,

don't understand what you exactly want, but if you want to open an other "window" beside your main application you should use QDialog instead of QFrame. Even a look at Using a Designer .ui File in Your Application (http://doc.trolltech.com/4.5/designer-using-a-ui-file.html) could be helpful.
