[Qt-interest] Help getting out of Gridlayout Hell

[Scott Aron Bloom]

If I have group box A with sub layout of type vertical, and a group box
B with a sub layout of type vertical.
Setting each of their margins to the same value, will have both sets of
group boxes vertically laid out widgets line up.

In code:
QWidget * widget = new QWidget;
QVBoxLayout * mainVb = new QVBoxLayout( widget );

QGroupBox * gb = new QGroupBox;
mainVb >addWidget( gb );
QVBoxLayout * vb = new QVBoxLayout( gb );

vb->addWidget(new QLabel( "label1" ) );
vb->addWidget(new QLabel( "label2" ) ); 
vb->addWidget(new QLabel( "label3" ) );

gb = new QGroupBox;
mainVb >addWidget( gb );
vb = new QVBoxLayout( gb );
vb->addWidget(new QLabel( "label4" ) );
vb->addWidget(new QLabel( "label5" ) ); 
vb->addWidget(new QLabel( "label6" ) );


widget->show();


now.. if I add a third widget, that item WILL certainly NOT line up with
the sub lablels...

mainVb->addWidget( new QLabel( "label7" ) )


And in my view it shouldn't, since you grouped the subs anyway
