Hi. What is problems?

Qt Code:

Switch view

#ifndef FINDDIALOG_H_055
#define FINDDIALOG_H_055
 
#include <QDialog>
 
class QCheckBox;
class QLabel;
class QLineEdit;
class QPushButton;
 
class FindDialog: public QDialog
{
	Q_OBJECT;
 
public:
	FindDialog(QWidget* parent=0);
 
signals:
	void findNext(const QString& str, Qt::CaseSensitivity cs);
	void findPrev(const QString& str, Qt::CaseSensitivity cs);
 
private slots:
	void findClicked();
	void enableFindButton(const QString& text);
 
private:
	QLabel* label;
	QLineEdit* lineEdit;
	QCheckBox* caseCheckBox;
	QCheckBox* backwardCheckBox;
	QPushButton* findButton;
	QPushButton* closeButton;
};
 
#endif	// FINDDIALOG_H_055

#ifndef FINDDIALOG_H_055
#define FINDDIALOG_H_055

#include <QDialog>

class QCheckBox;
class QLabel;
class QLineEdit;
class QPushButton;

class FindDialog: public QDialog
{
	Q_OBJECT;

public:
	FindDialog(QWidget* parent=0);

signals:
	void findNext(const QString& str, Qt::CaseSensitivity cs);
	void findPrev(const QString& str, Qt::CaseSensitivity cs);

private slots:
	void findClicked();
	void enableFindButton(const QString& text);

private:
	QLabel* label;
	QLineEdit* lineEdit;
	QCheckBox* caseCheckBox;
	QCheckBox* backwardCheckBox;
	QPushButton* findButton;
	QPushButton* closeButton;
};

#endif	// FINDDIALOG_H_055

class FindDialog is used for your aim! You may this class in your aplications! I don't understand you! Why this class isn't use in your application?

Actually i dont want to use it as a separate dialog in my application, I just want that when I enter text in the text box and presse enter key,then It displays all the result related to the text in the tree widget.

Pls preview the attachment, I want same for my application, like same box in which text to be find is written with same icon on the left and same close button on the right of the box in which text to be find is written.
