详细描述
QToolButton类提供了用于命令或者选项的可以快速访问的按钮,通常可以用在QToolBar里面。
工具按钮是提供对特定命令或者选项快速访问的特殊按钮。和普通的命令按钮不同,工具按钮通常不显示文本标签,而是图标。它的经典用法事选择工具,例如在一个绘图程序中的“笔”工具。这个被QToolButton作为切换按钮重新实现。(请参考setToggleButton())。
QToolButton支持自动浮起。在自动浮起模式中,按钮只有在鼠标指向它的时候才绘制三维的框架。当按钮被用在QToolBar里面的时候,这个特征会自动被启用。可以使用setAutoRaise()来改变它。
工具按钮的图标是被设置为QIconSet。这使得它可以为失效和激活状态指定不同的像素映射。当按钮的功能不可用的时候,失效的像素映射被使用。当因为用户用鼠标指向按钮而自动浮起时,激活的像素映射被显示。
按钮的外观和尺寸可以通过setUsesBigPixmap()和setUsesTextLabel()来调节。当被用在QToolBar里面时,按钮会自动地调节来适合QMainWindow的设置(请参考QMainWindow::setUsesTextLabel()和QMainWindow::setUsesBigPixmaps())。
工具按钮可以提供一个弹出菜单的额外选择。这个特征有时对于网页浏览器中的“后退”按钮是有用的。在按下按钮一段时间之后,一个菜单会弹出来显示所有可以后退浏览的可能页面。你可以使用setPopup()来为QToolButton设置一个弹出菜单。默认延时是600毫秒,你可以使用setPopupDelay()来调节它。
一个有QToolbutton的浮动的QToolbar
也可以参考QPushButton、QToolBar、QMainWindow、图形用户界面设计手册:推动按钮和基本窗口部件。
成员函数文档
QToolButton::QToolButton ( QWidget*parent, constchar*name = 0 )
构造一个父对象为parent并且名称为name的空工具按钮。QToolButton::QToolButton ( constQIconSet&iconSet, constQString&textLabel, constQString&grouptext, QObject*receiver, constchar*slot, QToolBar*parent, constchar*name = 0 )
构造一个父对象为parent(必须为QToolBar)并且名称为name的工具按钮。工具按钮将显示iconSet,它的文本标签和工具提示设置为textLabel并且它的状态条信息设置为grouptext。它将被连接到receiver对象的slot槽。
QToolButton::QToolButton ( ArrowTypetype, QWidget*parent, constchar*name = 0 )
把工具按钮构造为箭头按钮。ArrowType type定义了箭头的方向。可用的值为LeftArrow、RightArrow、UpArrow和DownArrow。箭头按钮的自动重复默认是打开的。
parent和name参数被发送给QWidget构造函数。
QToolButton::~QToolButton ()
销毁这个对象并且释放任何被分配的资源。bool QToolButton::autoRaise () const
如果自动浮起有效,返回真,否则返回假。详细情况请参考“autoRaise”属性。
QIconSet QToolButton::iconSet () const
返回提供显示在按钮上的图标的图标集。详细情况请参考“iconSet”属性。
QIconSet QToolButton::iconSet ( boolon ) const
这是一个重载成员函数,提供了方便。它的行为基本上和上面的函数相同。这个函数是废弃的。它的提供只是为了保证旧代码能够工作。我们强烈建议在新代码中不要使用它。
从Qt 3.0开始,QIconSet可以包含开和关两套图标了。
为了方便移植,这个函数将忽略on参数并且返回iconSet属性。如果你依赖于on参数,你也许要把你的代码升级到QIconSet开/关机制了。
QIconSet QToolButton::offIconSet () const
返回当按钮在“关”状态下被使用的图标集。详细情况请参考“offIconSet”属性。
QIconSet QToolButton::onIconSet () const
返回当按钮在“开”状态下被使用的图标集。详细情况请参考“onIconSet”属性。
void QToolButton::openPopup ()
打开(弹出)关联的弹出菜单。如果没有这样的菜单,这个函数就什么也不做。直到这个弹出菜单已经被用户关闭,这个函数才会返回。QPopupMenu* QToolButton::popup () const
返回关联的弹出菜单,或者如果没有定义弹出菜单,返回0。也可以参考setPopup()。
int QToolButton::popupDelay () const
返回在按下按钮和出现关联的弹出按钮之间的以毫秒为单位的时间。详细情况请参考“popupDelay”属性。
void QToolButton::setAutoRaise ( boolenable )
设置自动浮起是否有效为enable。详细情况请参考“autoRaise”属性。
void QToolButton::setIconSet ( constQIconSet& ) [虚]
设置提供显示在按钮上的图标的图标集。详细情况请参考“iconSet”属性。
void QToolButton::setIconSet ( constQIconSet&set, boolon )
这是一个重载成员函数,提供了方便。它的行为基本上和上面的函数相同。这个函数是废弃的。它的提供只是为了保证旧代码能够工作。我们强烈建议在新代码中不要使用它。
从Qt 3.0开始,QIconSet可以包含开和关两套图标了。
为了方便移植,这个函数将忽略on参数并且返回iconSet属性。如果你依赖于on参数,你也许要把你的代码升级到QIconSet开/关机制了。
也可以参考iconSet和QIconSet::State。
void QToolButton::setOffIconSet ( constQIconSet& )
设置当按钮在“关”状态下被使用的图标集。详细情况请参考“offIconSet”属性。
void QToolButton::setOn ( boolenable ) [虚 槽]
设置按钮是否为开为enable。详细情况请参考“on”属性。
void QToolButton::setOnIconSet ( constQIconSet& )
设置当按钮在“开”状态下被使用的图标集。详细情况请参考“onIconSet”属性。
void QToolButton::setPopup ( QPopupMenu*popup )
把弹出菜单popup和这个工具按钮关联起来。每次在工具按钮被按下一定时间之后,弹出菜单将被显示。一个经典的实例是一些网页浏览器的工具条上的“后退”按钮。如果用户点击它,浏览器简单地后退浏览到上一页。如果用户按下这个按钮一段时间,工具按钮会显示一个包含当前历史列表的菜单。
弹出菜单的所有权不会被传递给工具按钮。
也可以参考popup()。
void QToolButton::setPopupDelay ( intdelay )
设置在按下按钮和出现关联的弹出按钮之间的以毫秒为单位的时间。详细情况请参考“popupDelay”属性。
void QToolButton::setTextLabel ( constQString& ) [槽]
设置按钮的标签。详细情况请参考“textLabel”属性。
void QToolButton::setTextLabel ( constQString&newLabel, booltipToo ) [虚 槽]
这是一个重载成员函数,提供了方便。它的行为基本上和上面的函数相同。设置按钮的标签为newLabel并且如果tipToo为真,自动地把工具提示也设置为newLabel。
void QToolButton::setToggleButton ( boolenable ) [虚 槽]
设置工具按钮是否是切换按钮为enable。详细情况请参考“toggleButton”属性。
void QToolButton::setUsesBigPixmap ( boolenable ) [虚 槽]
设置工具按钮是否使用大的像素映射为enable。详细情况请参考“usesBigPixmap”属性。
void QToolButton::setUsesTextLabel ( boolenable ) [虚 槽]
设置工具按钮是否在按钮像素映射下方显示标签为enable。详细情况请参考“usesTextLabel”属性。
QString QToolButton::textLabel () const
返回按钮的标签。详细情况请参考“textLabel”属性。
void QToolButton::toggle () [槽]
切换工具按钮的状态。这个函数对于非切换按钮无效。
也可以参考toggleButton和toggled()。
bool QToolButton::uses3D () const [保护]
如果这个按钮应该被使用浮起的边缘绘制,返回真,否则返回假。也可以参考drawButton()。
bool QToolButton::usesBigPixmap () const
如果工具按钮使用大地像素映射,返回真,否则返回假。详细情况请参考“usesBigPixmap”属性。
bool QToolButton::usesTextLabel () const
如果工具按钮在按钮像素映射下方显示标签,返回真,否则返回假。详细情况请参考“usesTextLabel”属性。
属性文档
bool autoRaise
这个属性保存的是自动浮起是否生效。
默认是失效的(也就是假)。
通过setAutoRaise()设置属性值并且通过autoRaise()来获得属性值。
QIconSet iconSet
这个属性保存的是提供显示在按钮上的图标的图标集。
设置这个属性把QToolButton::pixmap设置为零像素映射。没有默认图标集。
也可以参考pixmap、toggleButton和on。
通过setIconSet()设置属性值并且通过iconSet()来获得属性值。
QIconSet offIconSet
这个属性保存的是当按钮在“关”状态时使用的图标集。
这个函数是废弃的。它的提供只是为了保证旧代码能够工作。我们强烈建议在新代码中不要使用它。
从Qt 3.0开始,QIconSet可以包含开和关两套图标了。现在QToolButton::iconSet属性替换了QToolButton::onIconSet和QToolButton::offIconSet。
为了方便移植,这个函数将忽略on参数并且返回iconSet属性。如果你依赖于on参数,你也许要把你的代码升级到QIconSet开/关机制了。
也可以参考iconSet和QIconSet::State。
通过setOffIconSet()设置属性值并且通过offIconSet()来获得属性值。
bool on
这个属性保存的是工具按钮是否为开。
这个属性对于非切换按钮无效。默认为假(也就是关)。
也可以参考toggleButton和toggle()。
通过setOn()设置属性值。
QIconSet onIconSet
这个属性保存的是当按钮在“开”状态时使用的图标集。
这个函数是废弃的。它的提供只是为了保证旧代码能够工作。我们强烈建议在新代码中不要使用它。
从Qt 3.0开始,QIconSet可以包含开和关两套图标了。现在QToolButton::iconSet属性替换了QToolButton::onIconSet和QToolButton::offIconSet。
