scrolling stops in some circumstances Basically, if the user moves the mouse after scrolling the area with the wheel, we should release the time based lock we use to avoid unwanted widget changes mid-scroll immediately. Otherwise it's impossible to scroll wheel->move mouse onto widget->wheel to change widget value quickly.

class QgsScrollArea : QScrollArea

%Docstring(signature="appended")
|
|
A QScrollArea subclass with improved scrolling behavior.
|
|
|
|
:py:class:`QgsScrollArea` should be used instead of QScrollArea widgets.
|
|
In most cases the use is identical, however :py:class:`QgsScrollArea`
|
|
has extra logic to avoid wheel events changing child widget
|
|
values when the mouse cursor is temporarily located over
|
|
a child widget during a scroll event.
|
|
|
|
All QGIS code and plugins should use :py:class:`QgsScrollArea` in place
|
|
of QScrollArea.

Constructor for QgsScrollArea.

void scrollOccurred();
|

Should be called when a scroll occurs on with the

QScrollArea itself or its child :py:func:`~QgsScrollArea.viewport`.

Returns ``True`` if a scroll recently occurred within

|

Sets whether the scroll area only applies vertical.
|
|
|
|
If set to ``True``, then scroll area children will resize horizontally to match the width of
|
|
the scroll area widget.
