Reimplementado de QWidget.
| void QSpinWidget::mouseMoveEvent | ( | QMouseEvent * | e | ) | [protected, virtual] |
This event handler, for event e, can be reimplemented in a subclass to receive mouse move events for the widget.
If mouse tracking is switched off, mouse move events only occur if a mouse button is pressed while the mouse is being moved. If mouse tracking is switched on, mouse move events occur even if no mouse button is pressed.
QMouseEvent::pos() reports the position of the mouse cursor, relative to this widget. For press and release events, the position is usually the same as the position of the last mouse move event, but it might be different if the user's hand shakes. This is a feature of the underlying window system, not Qt.

| void QSpinWidget::mousePressEvent | ( | QMouseEvent * | e | ) | [protected, virtual] |

| void QSpinWidget::mousePressEvent | ( | QMouseEvent * | e | ) | [protected, virtual] |
This event handler, for event e, can be reimplemented in a subclass to receive mouse press events for the widget.
If you create new widgets in the mousePressEvent() the mouseReleaseEvent() may not end up where you expect, depending on the underlying window system (or X11 window manager), the widgets' location and maybe more.
The default implementation implements the closing of popup widgets when you click outside the window. For other widget types it does nothing.

| void QSpinWidget::paintEvent | ( | QPaintEvent * | ) | [protected, virtual] |
This event handler can be reimplemented in a subclass to receive paint events.
A paint event is a request to repaint all or part of the widget. It can happen as a result of repaint() or update(), or because the widget was obscured and has now been uncovered, or for many other reasons.
Many widgets can simply repaint their entire surface when asked to, but some slow widgets need to optimize by painting only the requested region: QPaintEvent::region(). This speed optimization does not change the result, as painting is clipped to that region during event processing. QListView and QCanvas do this, for example.
Qt also tries to speed up painting by merging multiple paint events into one. When update() is called several times or the window system sends several paint events, Qt merges these events into one event with a larger region (see QRegion::unite()). repaint() does not permit this optimization, so we suggest using update() when possible.
When the paint event occurs, the update region has normally been erased, so that you're painting on the widget's background. There are a couple of exceptions and QPaintEvent::erased() tells you whether the widget has been erased or not.
The background can be set using setBackgroundMode(), setPaletteBackgroundColor() or setBackgroundPixmap(). The documentation for setBackgroundMode() elaborates on the background; we recommend reading it.

| void QSpinWidget::resizeEvent | ( | QResizeEvent * | ) | [protected, virtual] |
This event handler can be reimplemented in a subclass to receive widget resize events. When resizeEvent() is called, the widget already has its new geometry. The old size is accessible through QResizeEvent::oldSize().
The widget will be erased and receive a paint event immediately after processing the resize event. No drawing need be (or should be) done inside this handler.
Widgets that have been created with the WNoAutoErase flag will not be erased. Nevertheless, they will receive a paint event for their entire area afterwards. Again, no drawing needs to be done inside this handler.
The default implementation calls updateMask() if the widget has automatic masking enabled.

| void QSpinWidget::styleChange | ( | QStyle & | ) | [protected, virtual] |
This virtual function is called when the style of the widgets changes. oldStyle is the previous GUI style; you can get the new style from style().
Reimplement this function if your widget needs to know when its GUI style changes. You will almost certainly need to update the widget using update().
The default implementation updates the widget including its geometry.

| void QSpinWidget::wheelEvent | ( | QWheelEvent * | e | ) | [protected, virtual] |
This event handler, for event e, can be reimplemented in a subclass to receive wheel events for the widget.
If you reimplement this handler, it is very important that you ignore() the event if you do not handle it, so that the widget's parent can interpret it.
The default implementation ignores the event.

| void QSpinWidget::windowActivationChange | ( | bool | oldActive | ) | [protected, virtual] |
This virtual function is called for a widget when its window is activated or deactivated by the window system. oldActive is the previous state; you can get the new setting from isActiveWindow().
Reimplement this function if your widget needs to know when its window becomes activated or deactivated.
The default implementation updates the visible part of the widget if the inactive and the active colorgroup are different for colors other than the highlight and link colors.
