详细描述
QFrame类是有框架的窗口部件的基类。它绘制框架并且调用一个虚函数drawContents()来填充这个框架。这个函数是被子类重新实现的。这里至少还有两个有用的函数:drawFrame()和frameChanged()。
QPopupMenu使用这个来把菜单“升高”,高于周围屏幕。QProgressBar有“凹陷”的外观。QLabel有平坦的外观。这些有框架的窗口部件可以被改变。
QLabel label(...); label.setFrameStyle( QFrame::Panel | QFrame::Raised ); label.setLineWidth( 2 ); QProgressBar pbar(...); label.setFrameStyle( QFrame::NoFrame );
QFrame类也能够直接被用来创建没有任何内容的简单框架,尽管通常情况下,你要用到QHBox或QVBox,因为它们可以自动的布置你放到框架中的窗口部件。
框架窗口部件有四个属性:frameStyle()、lineWidth()、midLineWidth()和margin()。
框架风格由框架外形和阴影风格决定。框架外形有NoFrame、Box、Panel、StyledPanel、PopupPanel、WinPanel、ToolBarPanel、MenuBarPanel、HLine和VLine,阴影风格有Plain、Raised和Sunken。
线宽就是框架边界的宽度。
中间线宽指定的是在框架中间的另外一条线的宽度,它使用第三种颜色来得到一个三维的效果。注意中间线只有在Box、HLine和VLine这些凸起和凹陷的框架中才被绘制。
边白就是框架和框架内容之间的间隙。
这个表显示的是风格和宽度的绝大多数有用的组合(和一些没有用处的):
也可以参考抽象窗口部件类。
成员类型文档
QFrame::Shadow
这个枚举类型定义了QFrame的框架所使用的三维效果。当前定义的效果有:
- QFrame::Plain - 框架和内容看来和周围一样高
- QFrame::Raised - 框架和内容看起来凸起
- QFrame::Sunken - 框架和内容看起来凹陷
- QFrame::MShadow - 内部的,对于阴影的掩码
Shadow和QFrame::Shape、lineWidth()和midLineWidth()相互作用。类文档中的框架的图片描绘的比这些词语更好。
也可以参考QFrame::Shape、lineWidth和midLineWidth。
QFrame::Shape
这个枚举类型定义了QFrame的框架所使用的外形。当前定义的效果有:
- NoFrame - QFrame不画任何东西
- Box - QFrame在它的内容周围画一个框
- Panel - QFrame画一个平板使内容看起来凸起或者凹陷
- WinPanel - 像Panel,但QFrame绘制三维效果的方式和Microsoft Windows 95(及其它)的一样
- ToolBarPanel - QFrame调用QStyle::drawToolBarPanel()
- MenuBarPanel - QFrame调用QStyle::drawMenuBarPanel()
- HLine - QFrame绘制一个水平线,但没有框任何东西(作为分隔是有用的)
- VLine - QFrame绘制一个竖直线,但没有框任何东西(作为分隔是有用的)
- StyledPanel - QFrame调用QStyle::drawPanel()
- PopupPanel - QFrame调用QStyle::drawPopupPanel()
当它不调用QStyle时,Shape和QFrame::Shadow、lineWidth()和midLineWidth()相互作用来创建整个结果。类文档中的框架的图片描绘的比这些词语更好。
也可以参考QFrame::Shadow、QFrame::style()和QStyle::drawPrimitive()。
成员函数文档
QFrame::QFrame ( QWidget*parent = 0, constchar*name = 0, WFlagsf = 0 )
构造一个框架风格为NoFrame并且1像素框架宽度的框架窗口部件。parent、name和f参数被传递给QWidget的构造函数。
QRect QFrame::contentsRect () const
返回框架内的矩形。详细情况请参考“contentsRect”属性。
void QFrame::drawContents ( QPainter* ) [虚 保护]
绘制框架内容的虚函数。当你得到QPainter时,它已经被打开,并且在你离开时,它也必须是打开的。绘制工具的转换在真个过程中是被关闭的。如果你转换绘制工具,记得考虑框架并且在返回前重置转换。
这个函数在子类中被重新实现用来绘制框架中的一些东西。它只能在contentsRect()内绘制。默认函数什么都不做。
也可以参考contentsRect和QPainter::setClipRect()。
在QLabel、a href="qlcdnumber.html#drawContents">QLCDNumber、QMenuBar和QPopupMenu中重新实现。
void QFrame::drawFrame ( QPainter*p ) [虚 保护]
使用绘制工具p和当前框架属性和颜色组绘制框架。框架内的矩形不受影响。这个函数是虚函数,但通常情况下你不需要重新实现它。如果你要做,注意QPainter已经被打开并且必须保持打开的状态。
也可以参考frameRect、contentsRect、drawContents()、a href="#frameStyle">frameStyle()和palette。
void QFrame::frameChanged () [虚 保护]
当框架风格、线宽和中间线宽发生改变时,这个虚函数被调用。这个函数在子类中可以被重新实现,它需要知道什么时候框架属性发生变化。
默认实现是调用update()。
QRect QFrame::frameRect () const
返回框架矩形。详细情况请参考“frameRect”属性。
Shadow QFrame::frameShadow () const
返回来自框架风格的框架阴影值。详细情况请参考“frameShadow”属性。
Shape QFrame::frameShape () const
返回来自框架风格的框架外形值。详细情况请参考“frameShape”属性。
int QFrame::frameStyle () const
返回框架风格。默认值是QFrame::NoFrame。
也可以参考setFrameStyle()、frameShape和frameShadow。
实例:scrollview/scrollview.cpp。
int QFrame::frameWidth () const
返回所绘制的框架的宽度。详细情况请参考“frameWidth”属性。
int QFrame::lineWidth () const
返回线宽。详细情况请参考“lineWidth”属性。
int QFrame::margin () const
返回边白的宽度。详细情况请参考“margin”属性。
int QFrame::midLineWidth () const
返回中间线的宽度。详细情况请参考“midLineWidth”属性。
void QFrame::paintEvent ( QPaintEvent*event ) [虚 保护]
处理绘制事件event。绘制框架和内容。
打开框架上的绘制工具并且调用drawFrame(),然后是drawContents()。
实例:life/life.cpp和qfd/fontdisplayer.cpp。
从QWidget中重新实现的。
在a href="qttableview.html#paintEvent">QtTableView中被重新实现。
void QFrame::resizeEvent ( QResizeEvent*e ) [虚 保护]
处理重定义大小事件e。对于被重新定义大小的窗口部件,调整框架矩形。框架矩形是弹性的,并且周围的区域是固定的。
结果框架矩形也许是零或者无效。你可以使用setMinimumSize()来避免这种可能。
如果框架矩形已经是一个零矩形,那么将不会做任何事。
实例:life/life.cpp。
从QWidget中重新实现的。
void QFrame::setFrameRect ( constQRect& ) [虚]
设置框架矩形。详细情况请参考“frameRect”属性。
void QFrame::setFrameShadow ( Shadow )
设置来自框架风格的框架阴影值。详细情况请参考“frameShadow”属性。
void QFrame::setFrameShape ( Shape )
设置来自框架风格的框架外形值。详细情况请参考“frameShape”属性。
void QFrame::setFrameStyle ( intstyle ) [虚]
设置框架风格为style。style是框架外形和框架阴影风格的位或操作。详细情况请参考类文档中的框架的图片。
框架外形有:
- NoFrame不绘制任何东西。自然地,如果你使用这个,你就不用指定阴影风格。
- Box绘制矩形框。内容看起来和周围的屏幕一样高,但是边界本身也许凸起或凹陷。
- Panel绘制矩形凸起或凹陷的平板。
- StyledPanel绘制一个依赖于当前GUI风格的矩形平板。它可能是凸起的,也可能是凹陷的。
- PopupPanel是用来绘制用于弹出窗口的框架。它的外观也依赖于当前GUI风格,通常和StyledPanel一样。
- ToolBarPanel是用来绘制用于工具条的框架。它的外观也依赖于当前GUI风格。
- MenuBarPanel是用来绘制用于菜单条的框架。它的外观也依赖于当前GUI风格。
- LineEditPanel是用来绘制用于行编辑的框架。它的外观也依赖于当前GUI风格。
- TabWidgetPanel是用来绘制用于Tab窗口部件的框架。它的外观也依赖于当前GUI风格。
- WinPanel绘制一个和Windows 95中一样的凸起或凹陷的矩形平板。指定这个外形设置线宽为2像素。WinPanel的提供是为了兼容性。为了使GUI风格独立,我们建议使用StyledPanel替换它。
- HLine绘制一条水平线(垂直中央)。
- VLine绘制一条垂直线(水平中央)。
阴影风格有:
- Plain使用调色板的前景颜色绘制(没有任何三维效果)。
- Raised使用当前颜色组的亮和暗颜色绘制三维的凸起线。
- Sunken使用当前颜色组的亮和暗颜色绘制三维的凹陷线。
如果被指定的中间线宽大于0,在Raised或Sunken、Box÷HLine和VLine框架中会被绘制一条另外的线。当前颜色组的中间颜色被用于绘制中间线。
也可以参考Illustration、frameStyle()、colorGroup和QColorGroup。
实例:cursor/cursor.cpp、layout/layout.cpp、listboxcombo/listboxcombo.cpp、rangecontrols/rangecontrols.cpp、scrollview/scrollview.cpp、tabdialog/tabdialog.cpp和tictac/tictac.cpp。
void QFrame::setLineWidth ( int ) [虚]
设置线宽。详细情况请参考“lineWidth”属性。
void QFrame::setMargin ( int ) [虚]
设置边白的宽度。详细情况请参考“margin”属性。
void QFrame::setMidLineWidth ( int ) [虚]
设置中间线的宽度。详细情况请参考“midLineWidth”属性。
属性文档
QRect contentsRect
这个属性保存的是框架内的矩形。
使用contentsRect()来得到这个属性值。
也可以参考frameRect和drawContents()。
QRect frameRect
这个属性保存的是框架矩形。
框架矩形是被画的框架所在的矩形。默认情况下,这是整个窗口部件。设置这个属性不会导致窗口部件更新。
如果这个属性被设置为零矩形(比如QRect(0, 0, 0, 0)),那么框架矩形将会等于窗口部件矩形。
也可以参考contentsRect。
使用setFrameRect()来设置这个属性值并且使用frameRect()来得到这个属性值。
Shadow frameShadow
这个属性保存的是来自框架风格的框架阴影值。
使用setFrameShadow()来设置这个属性值并且使用frameShadow()来得到这个属性值。
也可以参考frameStyle()和frameShape。
Shape frameShape
这个属性用来操存的是来自框架风格的框架外形值。
使用setFrameShape()来设置这个属性值并且使用frameShape()来得到这个属性值。
也可以参考frameStyle()和frameShadow。
int frameWidth
这个属性保存的是被绘制的框架的宽度。
注意框架宽度依赖于框架风格,线宽和中间线宽。比如,NoFrame风格下,框架宽度为0,而Panel风格下,框架宽度和线宽相同。框架宽度也包括边白。
也可以参考lineWidth、midLineWidth、frameStyle()和margin。
使用frameWidth()来得到这个属性值。
int lineWidth
This property holds the line width. 这个属性保存的是线宽。
注意HLine和VLine的总线宽由frameWidth()给定,而不是lineWidth()。

边白是框架最里面的像素和contentsRect()最外面的像素之间的区域。它被包含在frameWidth()中。
边白是根据backgroundMode()被填充的。
默认值为0。
也可以参考lineWidth和frameWidth。
使用setMargin()来设置这个属性值并且使用margin()来得到这个属性值。
int midLineWidth
这个属性保存的是中间线的宽度。
默认值为0。
