[SOLVED] mainwindow pass data to dialog

xeroblast

hi,

i have this problem that dont know how to implement it.

i have this mainwindow that have a qtablewidget that you select an item in the qtablewidget and click the button to view its details.

the problem is i dont know how to pass the data from qtablewidget to the newly opened qdialog. i know how to get the data in the qtablewidget but i dont know how to pass it to qdialog.

this is how i open a qdialog..
@
MainWindow::MainWindow()
{
NewDialog dialog(this);
dialog.exec();
}

You may add new method for your dialog and set data into it, for example.
@
dialog.cpp

dialog.setData(myType myData)
{
ui.editText.setText(myData.textForEdit);
.......
}

.....
mainwindow.cpp

MainWindow::MainWindow()
{
NewDialog dialog(this);
dialog.setData(myData);
dialog.exec();
}

I tried this method and it's fine... it solved many problems i had with external variables...

The problem is that if i don't use a pushbutton or something the dialog don't realy recognize my new data...

I can't understand why...

Edit: I finally dont need to use my variables before a simple click...
I suppose this is why we call it a dialog...
