addWidget in qWidgetStack

[mickey]

Hi,
I need to add a widget on a widgetstack (and work!) but I need it is 1/2 of widgetStack (insert from Designer)

MyWidget top (&w, "top");	
top.setGeometry(QRect(0,0,w.WidgetStack->width()/2,w.WidgetStack->height()) );
int shared_top= w.WidgetStack->addWidget(&top);
cout << w.WidgetStack->width() << endl;
cout << w.WidgetStack->height() << endl;

MyWidget top (&w, "top");	
top.setGeometry(QRect(0,0,w.WidgetStack->width()/2,w.WidgetStack->height()) );
int shared_top= w.WidgetStack->addWidget(&top);
cout << w.WidgetStack->width() << endl;
cout << w.WidgetStack->height() << endl;

Why doesn't it work? (cout print 101 and 31 (why 31? Should be much more))
Thanks....

It won't work this way. The widget always occupies the whole widget stack geometry. You have to use layouts, spacers, sizeHints and sizePolicies to alter the behaviour.

yes thanks. I try this way but layout don't appear on myWidgetstack..

MyWidget top (&w, "top shared", w.myWidget1);	
QBoxLayout *layout = new QHBoxLayout(w.WidgetStack, 5, 0, "top" );
layout->addWidget(&top);

MyWidget top (&w, "top shared", w.myWidget1);	
QBoxLayout *layout = new QHBoxLayout(w.WidgetStack, 5, 0, "top" );
layout->addWidget(&top);

I need to take w parent of top.

Layout needs to be assigned to a widget. Something like this:

QWidget *w = new QWidget(this);
QHBoxLayout *l = new QHBoxLayout();
//...
QWidget *chld = new QWidget(this);
l->addWidget(chld);
//...
w->setLayout(l);
//...
stackedWidget->addWidget(w);

QWidget *w = new QWidget(this);
QHBoxLayout *l = new QHBoxLayout();
//...
QWidget *chld = new QWidget(this);
l->addWidget(chld);
//...
w->setLayout(l);
//...
stackedWidget->addWidget(w);

Sorry but my 'w' is: MainForm w;

QWidget *w = new QWidget(this);
QHBoxLayout *l = new QHBoxLayout();
QWidget *chld = new QWidget(this);
l->addWidget(chld);
w->setLayout(l);
stackedWidget->addWidget(w);

QWidget *w = new QWidget(this);
QHBoxLayout *l = new QHBoxLayout();
QWidget *chld = new QWidget(this);
l->addWidget(chld);
w->setLayout(l);
stackedWidget->addWidget(w);

In anyway, your code get this error:

error C2248: 'QWidget::setLayout' : cannot access private member declared in class 'QWidget'

error C2248: 'QWidget::setLayout' : cannot access private member declared in class 'QWidget'

I am in main.cpp...

I am in main.cpp...

This should not be done there Setting layouts should be done in the constructor of a widget. Nevertheless QWidget::setLayout() is public... Aa... you're using Qt3. Then setting the widget as a parent to a layout should be enough.

Sory your code don't compile, maybe bacause my widget is a QGLWidget and I put it in costructor of myGLWidget....

QWidget *w = new QWidget(this);
QHBoxLayout *l = new QHBoxLayout();
QWidget *chld = new QWidget(this);
l->addWidget(chld);
//w->setLayout(l);

QWidget *w = new QWidget(this);
QHBoxLayout *l = new QHBoxLayout();
QWidget *chld = new QWidget(this);
l->addWidget(chld);
//w->setLayout(l);

If I comment last istruction don't display.....

[mickey]

HI, this code seems ok. But it don't put 'l' on widget w. w->setlayout(l) don't compile.

QWidget *w = new QWidget;
	QHBoxLayout *l = new QHBoxLayout(this);
	l->addWidget(top);
	//...........
	this->WidgetStack->addWidget(w);

QWidget *w = new QWidget;
	QHBoxLayout *l = new QHBoxLayout(this);
	l->addWidget(top);
	//...........
	this->WidgetStack->addWidget(w);

myGLWidget 'top appear in a small square on toolbar. I don't know how put it on widget w.
Any hints?
