qt design and adding other code

[cxl2253]

i use the QT Designer and create a simple UI file inhertied from QMainwindow,in its Construct function,I add a treewidget and textedit component, but how to layout them?
I Add a QVboxlayout, but it did not work.
Following is my code :

frmMainWindow::frmMainWindow()
{
	setupUi(this);
	connect(radioButton,SIGNAL(toggled(bool)),this,SLOT(oncheckBoxclick(bool)));
 
	QVBoxLayout *vboxlayout=new QVBoxLayout();
 
	QTreeWidget *treeWidget = new QTreeWidget(this);
	//treeWidget->setGeometry(QRect(0,0,200,100));
	treeWidget->setColumnCount(1);
	QList<QTreeWidgetItem *> items;
	for (int i = 0; i < 100; ++i)
		items.append(new QTreeWidgetItem((QTreeWidget*)0, QStringList(QString("item: %1").arg(i))));
	treeWidget->insertTopLevelItems(0, items);
	treeWidget->setSizeIncrement(10,50);
	treeWidget->setMinimumSize(100,500) ;
	treeWidget->setLayout(vboxlayout);
 
	QTextEdit *edit=new QTextEdit(this);
	edit->insertPlainText("11111111111111111111111111111111111111111111111111");
	edit->insertPlainText("22222222222222222222222222222222222222222222222222");
	edit->setMinimumSize(100,100);
	edit->setLayout(vboxlayout);
 
	vboxlayout->addSpacing(6);
	//vboxlayout->addWidget(treeWidget);
	//vboxlayout->addWidget(edit);
	vboxlayout->addStretch(100) ;
 
	setLayout(vboxlayout);
}

frmMainWindow::frmMainWindow()
{
	setupUi(this);
	connect(radioButton,SIGNAL(toggled(bool)),this,SLOT(oncheckBoxclick(bool)));

	QVBoxLayout *vboxlayout=new QVBoxLayout();

	QTreeWidget *treeWidget = new QTreeWidget(this);
	//treeWidget->setGeometry(QRect(0,0,200,100));
	treeWidget->setColumnCount(1);
	QList<QTreeWidgetItem *> items;
	for (int i = 0; i < 100; ++i)
		items.append(new QTreeWidgetItem((QTreeWidget*)0, QStringList(QString("item: %1").arg(i))));
	treeWidget->insertTopLevelItems(0, items);
	treeWidget->setSizeIncrement(10,50);
	treeWidget->setMinimumSize(100,500) ;
	treeWidget->setLayout(vboxlayout);

	QTextEdit *edit=new QTextEdit(this);
	edit->insertPlainText("11111111111111111111111111111111111111111111111111");
	edit->insertPlainText("22222222222222222222222222222222222222222222222222");
	edit->setMinimumSize(100,100);
	edit->setLayout(vboxlayout);

	vboxlayout->addSpacing(6);
	//vboxlayout->addWidget(treeWidget);
	//vboxlayout->addWidget(edit);
	vboxlayout->addStretch(100) ;

	setLayout(vboxlayout);
}

other more, when I put the QTreewidget in QMainwindow directly in the QT Designer ,not create in Constructor using code,then uic the ui file and moc the file ,but when i run ,I can not focus all the widget ,even the form. it just like in dead loop and can not response to any event !


i save the ui to test.ui, then uic to get the test.h .
create cfrmmain.h from test.h, then moc the cfrmmain to get moc_cfrmmain.h,
implement the cfrmmain.h in cfrmmain.cpp.

/////// cfrmmain.h ////////
#include "test.h"
class frmMainWindow:public QMainWindow,public Ui::frmMainwindow 
{
Q_OBJECT
public:
	frmMainWindow();
//private slots:
//	void oncheckBoxclick(bool);
 
};

/////// cfrmmain.h ////////
#include "test.h"
class frmMainWindow:public QMainWindow,public Ui::frmMainwindow 
{
Q_OBJECT
public:
	frmMainWindow();
//private slots:
//	void oncheckBoxclick(bool);

};

#include "cfrmmain.h"
frmMainWindow::frmMainWindow()
{
  setupUi(this);
}

#include "cfrmmain.h"
frmMainWindow::frmMainWindow()
{
  setupUi(this);

    return app.exec();

Second question i have found a solution . Must give a layout for the mainwindow,now it can get the event.but how to arrange the manual widget ,maybe you can have good advice.

[wysota]

treeWidget->setLayout(vboxlayout);
edit->setLayout(vboxlayout);
setLayout(vboxlayout);

treeWidget->setLayout(vboxlayout);
edit->setLayout(vboxlayout);
setLayout(vboxlayout);

Didn't you by any chance mean the following?

vboxlayout->addWidget(treeWidget);
vboxlayout->addWidget(edit);
setLayout(vboxlayout);

vboxlayout->addWidget(treeWidget);
vboxlayout->addWidget(edit);
setLayout(vboxlayout);
