QProgressBar as a QTreeView item

[sergio87]

I did a little class to show a QProgressBar:

ProgressDialog.h:

#include <QDialog>
#include <QProgressBar>
#include <QHBoxLayout>
#ifndef PROGRESSDIALOG_H_
#define PROGRESSDIALOG_H_
 
class ProgressDialog : public QDialog{
 
	Q_OBJECT
 
public:
	ProgressDialog(QWidget *parent=0, int t=0);
	virtual ~ProgressDialog();
 
private:
	int total;
	QProgressBar *progressBar;
 
public slots:
	void setNuber(int num);
};
 
#endif /* PROGRESSDIALOG_H_ */

#include <QDialog>
#include <QProgressBar>
#include <QHBoxLayout>
#ifndef PROGRESSDIALOG_H_
#define PROGRESSDIALOG_H_

class ProgressDialog : public QDialog{

	Q_OBJECT

public:
	ProgressDialog(QWidget *parent=0, int t=0);
	virtual ~ProgressDialog();

private:
	int total;
	QProgressBar *progressBar;

public slots:
	void setNuber(int num);
};

#endif /* PROGRESSDIALOG_H_ */

}

}

This class has two paremeters imput:

1. QWidget *parent: When you call the constructor you can put it the Widget that you want. If you put 0, the it will open a new window.
2. int t: this is the total. For example, if you have 5 things to do, it will be 5. Every time you finish one thing you call the method setImage with the number you finished.

Sorry for my poor english!
