学习记录-Qt标准对话框

Qt中的标准对话框有以下：

1.文件对话框（QFileDialog）

1) 打开目录

QString	getExistingDirectory ( QWidget * parent = 0, const QString & caption = QString(), const QString & dir = QString(), Options options = ShowDirsOnly )

2)获取文件名

QString	getOpenFileName ( QWidget * parent = 0, const QString & caption = QString(), const QString & dir = QString(), const QString & filter = QString(), QString * selectedFilter = 0, Options options = 0 )

3)获取目录下所有文件名

QStringList	getOpenFileNames ( QWidget * parent = 0, const QString & caption = QString(), const QString & dir = QString(), const QString & filter = QString(), QString * selectedFilter = 0, Options options = 0 )

4)获取保存文件名

QString	getSaveFileName ( QWidget * parent = 0, const QString & caption = QString(), const QString & dir = QString(), const QString & filter = QString(), QString * selectedFilter = 0, Options options = 0 )

2.颜色对话框（QColorDialog）
3.字体对话框（QFontDialog）

4.输入对话框（QInputDialog）

double getDouble ( QWidget * parent, const QString & title, const QString & label,double value = 0, double min = -2147483647, double max = 2147483647, int decimals = 1, bool * ok = 0, Qt::WindowFlags flags = 0 )

int	getInt ( QWidget * parent, const QString & title, const QString & label, int value = 0, int min = -2147483647, int max = 2147483647, int step = 1, bool * ok = 0, Qt::WindowFlags flags = 0 )
QString	getItem ( QWidget * parent, const QString & title, const QString & label, const QStringList & items, int current = 0, bool editable = true, bool * ok = 0, Qt::WindowFlags flags = 0 )
QString	getText ( QWidget * parent, const QString & title, const QString & label, QLineEdit::EchoMode mode = QLineEdit::Normal, const QString & text = QString(), bool * ok = 0, Qt::WindowFlags flags = 0 )

5.消息对话框（QMessageBox）

void	about ( QWidget * parent, const QString & title, const QString & text )
void	aboutQt ( QWidget * parent, const QString & title = QString() )
StandardButton	critical ( QWidget * parent, const QString & title, const QString & text, StandardButtons buttons = Ok, StandardButton defaultButton = NoButton )
StandardButton	information ( QWidget * parent, const QString & title, const QString & text, StandardButtons buttons = Ok, StandardButton defaultButton = NoButton )
StandardButton	question ( QWidget * parent, const QString & title, const QString & text, StandardButtons buttons = Ok, StandardButton defaultButton = NoButton )
StandardButton	warning ( QWidget * parent, const QString & title, const QString & text, StandardButtons buttons = Ok, StandardButton defaultButton = NoButton )

6.打印对话框（QPrintDialog）

7.进度对话框（QProgressDialog）
