very basic layout problem

[wysota]

i directly show the widget with show().

Please show the full code of the widget's constructor. My wild guess would be that you call setupUi() after the code you posted which overrides the widget's layout you set earlier.

class test: public QWidget
{
	Q_OBJECT
 
public:
	test(QWidget *parent = 0);
	~test(){}
 
private:
	Ui::test ui;
};

class test: public QWidget
{
	Q_OBJECT

public:
	test(QWidget *parent = 0);
	~test(){}

private:
	Ui::test ui;
};

To copy to clipboard, switch view to plain text mode 

test::teset(QWidget *parent) : QWidget(parent)
{
	ui.setupUi(this);
 
	QHBoxLayout* hv = new QHBoxLayout(this);
	QTableWidget* rt = new QTableWidget(this);
 
	rt->setColumnCount(4);
	rt->setRowCount(10);
	rt->setRowHeight(0, 22);
	rt->verticalHeader()->hide();
 
	hv->addWidget(rt);
	setLayout(hv);
}

test::teset(QWidget *parent) : QWidget(parent)
{
	ui.setupUi(this);

	QHBoxLayout* hv = new QHBoxLayout(this);
	QTableWidget* rt = new QTableWidget(this);

	rt->setColumnCount(4);
	rt->setRowCount(10);
	rt->setRowHeight(0, 22);
	rt->verticalHeader()->hide();

	hv->addWidget(rt);
	setLayout(hv);
}

What happens if you comment out ui.setupUi(this) ?

If your designer UI is empty, which it must be since none of its contents would be added to the layout, why have the instance at all?

I think the point is that it is not empty and in the image we see two separate sets of widgets (with one widget in each set, actually) stacked on top of each other.

you are right. I am not sure what exactly the problem was, but removing all the designer stuff makes it work.


Essentially we end up with this:

class abc : public QWidget
{
public:
abc(QWidget* p = 0) : QWidget(p)
{
QHBoxLayout* lay = new QHBoxLayout(this);
QTableWidget* tw = new QTableWidget();
tw->setColumnCount(8);
tw->setRowCount(20);
lay->addWidget(tw);
setLayout(lay);
}
};

and that works fine. thanks for your help!

you are right. I am not sure what exactly the problem was,

The problem was two calls to setLayout().
