<h3 class="flags"><a name="AlignmentFlag-enum"></a>enum Qt::AlignmentFlag<br />flags Qt::Alignment</h3>

115

145

<p>This enum type is used to describe alignment. It contains horizontal and vertical flags that can be combined to produce the required effect.</p>

116

146

<p>The <a href="qt.html#TextElideMode-enum">TextElideMode</a> enum can also be used in many situations to fine-tune the appearance of aligned text.</p>

117

147

<p>The horizontal flags are:</p>

By default key compression is off, so widgets receive one key press event for each key press (or more, since autorepeat is usually on). If you turn it on and your program doesn't keep up with key input, Qt may try to compress key events so that more than one character can be processed in each event. For example, a word processor widget might receive 2, 3 or more characters in each <a href="qkeyevent.html#text">QKeyEvent::text</a>(), if the layout recalculation takes too long for the CPU. If a widget supports multiple character unicode input, it is always safe to turn the compression on. Qt performs key event compression only for printable characters. <a href="qt.html#Modifier-enum">Qt::Modifier</a> keys, cursor movement keys, function keys and miscellaneous action keys (e.g. Escape, Enter, Backspace, PrintScreen) will stop key event compression, even if there are more compressible key events available.

A tool window is often a small window with a smaller than usual title bar and decoration, typically used for collections of tool buttons. It there is a parent, the tool window will always be kept on top of it. If there isn't a parent, you may consider using Qt::WindowStaysOnTopHint as well. If the window system supports it, a tool window can be decorated with a somewhat lighter frame. It can also be combined with Qt::FramelessWindowHint. <br /> <br /> On Mac OS X, tool windows correspond to the <a href="http://developer.apple.com/documentation/Carbon/Conceptual/HandlingWindowsControls/hitb-wind_cont_concept/chapter_2_section_2.html">Floating</a> class of windows. This means that the window lives on a level above normal windows; it impossible to put a normal window on top of it. By default, tool windows will disappear when the application is inactive. This can be controlled by the <a href="qt.html#WidgetAttribute-enum">Qt::WA_MacAlwaysShowToolWindow</a> attribute.</td></tr>

1433

2642

<p>Returns true if the string <i>text</i> is likely to be rich text; otherwise returns false.</p>

1434

2643

<p>This function uses a fast and therefore simple heuristic. It mainly checks whether there is something that looks like a tag before the first line break. Although the result may be correct for common cases, there is no guarantee.</p>
