<hr><a name="details"></a><h2>Detailed Description</h2>


The TQFocusEvent class contains event parameters for widget focus
events.
<p> 
<p> Focus events are sent to widgets when the keyboard input focus
changes. Focus events occur due to mouse actions, keypresses (e.g.
Tab or Backtab), the window system, popup menus, keyboard
shortcuts or other application specific reasons. The reason for a
particular focus event is returned by <a href="#reason">reason</a>() in the appropriate
event handler.
<p> The event handlers <a href="ntqwidget.html#focusInEvent">TQWidget::focusInEvent</a>() and
<a href="ntqwidget.html#focusOutEvent">TQWidget::focusOutEvent</a>() receive focus events.
<p> Use <a href="#setReason">setReason</a>() to set the reason for all focus events, and
<a href="#resetReason">resetReason</a>() to set the reason for all focus events to the reason
in force before the last setReason() call.
<p> <p>See also <a href="ntqwidget.html#setFocus">TQWidget::setFocus</a>(), <a href="ntqwidget.html#focusPolicy-prop">TQWidget::focusPolicy</a>, and <a href="events.html">Event Classes</a>.

<hr><h2>Member Type Documentation</h2>
<h3 class=fn><a name="Reason-enum"></a>TQFocusEvent::Reason</h3>

<p> This enum specifies why the focus changed.
<ul>
<li><tt>TQFocusEvent::Mouse</tt> - because of a mouse action.
<li><tt>TQFocusEvent::Tab</tt> - because of a Tab press.
<li><tt>TQFocusEvent::Backtab</tt> - because of a Backtab press
(possibly including Shift/Control, e.g. Shift+Tab).
<li><tt>TQFocusEvent::ActiveWindow</tt> - because the window system made this window (in)active.
<li><tt>TQFocusEvent::Popup</tt> - because the application opened/closed a popup that grabbed/released focus.
<li><tt>TQFocusEvent::Shortcut</tt> - because of a keyboard shortcut.
<li><tt>TQFocusEvent::Other</tt> - any other reason, usually application-specific.
</ul><p> See the <a href="focus.html">keyboard focus overview</a> for more
about focus.

</h3>
Resets the reason for all future focus events to the value before
the last <a href="#setReason">setReason</a>() call.
<p> <p>See also <a href="#reason">reason</a>() and <a href="#setReason">setReason</a>().

<h3 class=fn>void <a name="setReason"></a>TQFocusEvent::setReason ( <a href="qfocusevent.html#Reason-enum">Reason</a>&nbsp;reason )<tt> [static]</tt>
