The TQDragMoveEvent class provides an event which is sent while a drag and drop is in progress.
< p > When a widget < a href = "tqwidget.html#setAcceptDrops" > accepts drop
events< / a > , it will receive this event repeatedly while the
drag is within the widget's boundaries. The widget should examine
the event to see what data it < a href = "qdropevent.html#provides" > provides< / a > , and < a href = "#accept" > accept< / a > () the drop if appropriate.
< p > Note that this class inherits most of its functionality from
< a href = "qdropevent.html" > TQDropEvent< / a > .
< p > See also < a href = "draganddrop.html" > Drag And Drop Classes< / a > and < a href = "events.html" > Event Classes< / a > .
< hr > < h2 > Member Function Documentation< / h2 >
< h3 class = fn > < a name = "TQDragMoveEvent" > < / a > TQDragMoveEvent::TQDragMoveEvent ( const < a href = "ntqpoint.html" > TQPoint< / a > & pos, < a href = "ntqevent.html#Type-enum" > Type< / a > type = DragMove )
< / h3 >
< p > Creates a TQDragMoveEvent for which the mouse is at point < em > pos< / em > ,
and the event is of type < em > type< / em > .
< p > < b > Warning:< / b > Do not create a TQDragMoveEvent yourself since these
objects rely on TQt's internal state.
< h3 class = fn > void < a name = "accept" > < / a > TQDragMoveEvent::accept ( const < a href = "ntqrect.html" > TQRect< / a > & r )
< / h3 >
< p > The same as < a href = "#accept" > accept< / a > (), but also notifies that future moves will
also be acceptable if they remain within the rectangle < em > r< / em > on the
widget: this can improve performance, but may also be ignored by
the underlying system.
< p > If the rectangle is < a href = "ntqrect.html#isEmpty" > empty< / a > , then
drag move events will be sent continuously. This is useful if the
source is scrolling in a timer event.
< p > Examples: < a href = "desktop-example.html#x1727" > desktop/desktop.cpp< / a > and < a href = "dirview-example.html#x1668" > dirview/dirview.cpp< / a > .
< h3 class = fn > < a href = "ntqrect.html" > TQRect< / a > < a name = "answerRect" > < / a > TQDragMoveEvent::answerRect () const
< / h3 >
< p > Returns the rectangle for which the acceptance of the move event
applies.
< h3 class = fn > void < a name = "ignore" > < / a > TQDragMoveEvent::ignore ( const < a href = "ntqrect.html" > TQRect< / a > & r )
< / h3 >
< p > The opposite of < a href = "#accept" > accept< / a > (const < a href = "ntqrect.html" > TQRect< / a > & ), i.e. says that moves within
rectangle < em > r< / em > are not acceptable (will be ignored).
< p > Example: < a href = "dirview-example.html#x1669" > dirview/dirview.cpp< / a > .
