<hr><a name="details"></a><h2>詳細描述</h2>
<p> Qt類是一個提供所需的像全局變量一樣的大量不同的標識符的命名空間。
<p>
<p> 通常情況下，你可以忽略這個類。<a href="qobject.html">QObject</a>和一些其它類繼承了它，所以在這個Qt命名空間中定義的所有標識符通常情況下都可以無限制的使用。
<p> 然而，有時你也許需要說<tt>Qt::black</tt>，而不僅僅是<tt>black</tt>，特別是在靜態功能函數中（比如一些類工廠）。
<p> <p>參見<a href="misc.html">雜項類</a>。
<hr><h2>成員類型文檔</h2>
<h3 class=fn><a name="AlignmentFlags-enum"></a>Qt::AlignmentFlags</h3>
<p> 這個枚舉類型是用來描述對齊方式的。它包含水平和垂直標記。
<p> 水平標記有：
<ul>
<li><tt>Qt::AlignAuto</tt> - 根據語言對齊。對于絕大多數是左對齊，對于阿拉伯語和希伯萊語是右對齊。
<li><tt>Qt::AlignLeft</tt> - 左對齊。
<li><tt>Qt::AlignRight</tt> - 右對齊。
<li><tt>Qt::AlignHCenter</tt> - 在可用空間中水平方向中間對齊。
<li><tt>Qt::AlignJustify</tt> - 在可用空間中調整文本。
并不是在所有情況下都可以工作，并且在一些情況下會被解釋成AlignAuto。
</ul><p> 垂直標記有：
<ul>
<li><tt>Qt::AlignTop</tt> - 上對齊。
<li><tt>Qt::AlignBottom</tt> - 下對齊。
<li><tt>Qt::AlignVCenter</tt> - 在可用空間中垂直方向中間對齊。
</ul><p> 你一次只能使用一次水平標記。這里有一個二維的標記：
<ul>
<li><tt>Qt::AlignCenter</tt> - 水平和垂直都中間對齊。
</ul><p> 你每次最多使用一個水平標記和一個垂直標記。<a href="#AlignmentFlags-enum">AlignCenter</a>既是水平也是垂直。
<p> 掩碼:
<ul>
<li><tt>Qt::AlignHorizontal_Mask</tt>
<li><tt>Qt::AlignVertical_Mask</tt>
</ul><p> 沖突的標記組合有未定義的意義。
<h3 class=fn><a name="ArrowType-enum"></a>Qt::ArrowType</h3>
<ul>
<li><tt>Qt::UpArrow</tt>
<li><tt>Qt::DownArrow</tt>
<li><tt>Qt::LeftArrow</tt>
<li><tt>Qt::RightArrow</tt>
</ul><p>
<h3 class=fn><a name="BGMode-enum"></a>Qt::BGMode</h3>
<p> 背景模式
<ul>
<li><tt>Qt::TransparentMode</tt>
<li><tt>Qt::OpaqueMode</tt>
</ul>
<h3 class=fn><a name="BackgroundMode-enum"></a>Qt::BackgroundMode</h3>
<p> 這個枚舉類型描述了窗口部件的背景是如何變化的，就像窗口部件的調色板變化一樣。
<p> 這里的背景就是當<a href="qwidget.html#paintEvent">paintEvent()</a>被調用的時候窗口部件所包含的東西。為了使閃爍最小化，在窗口部件它應是最普通的顏色或者像素映射。對于<a href="#BackgroundMode-enum">PaletteBackground</a>，使用colorGroup().brush（<a href="qcolorgroup.html#ColorRole-enum">QColorGroup::Background</a>）等等。這里也有三個特殊的值，列在了最后：
<ul>
<li><tt>Qt::PaletteForeground</tt>
<li><tt>Qt::PaletteBackground</tt>
<li><tt>Qt::PaletteButton</tt>
<li><tt>Qt::PaletteLight</tt>
<li><tt>Qt::PaletteMidlight</tt>
<li><tt>Qt::PaletteDark</tt>

<li><tt>Qt::NoBackground</tt> - 窗口部件在paintEvent()之前不被清空。如果窗口部件的繪畫事件一直在所有的像素上繪畫，使用這個模式既會很快也會沒有閃爍。
<li><tt>Qt::FixedColor</tt> - 窗口部件被一個固定的顏色清空，通常情況下不同于paletter()中的那些。使用<a href="qwidget.html#setPaletteBackgroundColor">setPaletteBackgroundColor()</a>來設置。
<li><tt>Qt::FixedPixmap</tt> - 窗口部件被一個固定的像素映射清空，通常情況下不同于paletter()中的那些。使用<a href="qwidget.html#setPaletteBackgroundPixmap">setPaletteBackgroundPixmap()</a>來設置。

</ul><p> 盡管<a href="#BackgroundMode-enum">FixedColor</a>和<a href="#BackgroundMode-enum">FixedPixmap</a>有時是正確的，如果你使用它們，當桌面顏色方案發生變化時，請測試一下你的應用程序。（在X11上，一個快速的測試方法是“./myapp -bg paleblue”。在Windows上，你必須使用控制面板。）

<li><tt>Qt::AltButton</tt> - 鍵盤上的Alt（或者Meta）鍵也被按下了。
<li><tt>Qt::MetaButton</tt> - 鍵盤上的Meta鍵也被按下了。
<li><tt>Qt::Keypad</tt> - 小鍵盤區的按鍵被按下了。
<li><tt>Qt::KeyButtonMask</tt> - Shift鍵、Control鍵和Alt鍵的一個掩碼。
