How to get Integer form Mainwindow to dialog[ui->slider->setvalue] when calling

[dbspl]

(sorry for my bad english, I'm not a nativce speaker)

Hi,

I use QT Creator, C++ and OpenCV. My mainprogram is working fine. But when I call my Dialog I get some unsolved problems.....

I have a Dialog and some Sliders in it.

In my Mainwindow there are some integer (from Header|Privat)).

Now I want to set the value of the sliders in the Dialog from the values ofn the integer from my mainwindow.

Can somone give me a little simple workaround, how to do?

I tried a lot of things, but now I am a little bit confused

I just need a little workaround how it should works in a simple way.....

I try like this:

//Mainwindow
 
void EBL_FK::keyPressEvent(QKeyEvent *e)
...
             mconfig= new myconfig(this);
             mconfig-> show();
              //try to set int POLX to value of sliderOLX in dialog named myconfig
             connect(this, SIGNAL(POLX),parent,SLOT(myconfig::ui->sliderOLX->setValue))
...

//Mainwindow

void EBL_FK::keyPressEvent(QKeyEvent *e)
...
             mconfig= new myconfig(this);
             mconfig-> show();
              //try to set int POLX to value of sliderOLX in dialog named myconfig
             connect(this, SIGNAL(POLX),parent,SLOT(myconfig::ui->sliderOLX->setValue))
...

thx a lot for your help

How would be the right way?

In C++, passing values from one object to another is done by calling methods.

Your dialog class needs one or more methods that can be called from where you use the dialog to pass the values into the dialog.
