QTouchEvent.TouchPoint ¶

概要 ¶

详细描述 ¶

class PySide2.QtGui.QTouchEvent. TouchPoint ( other ) ¶

PySide2.QtGui.QTouchEvent.TouchPoint([id=-1])

param id

int

param other

TouchPoint

构造 TouchPoint for use in a QTouchEvent .

PySide2.QtGui.QTouchEvent.TouchPoint. InfoFlag ¶

The values of this enum describe additional information about a touch point.

常量	描述
QTouchEvent.TouchPoint.Pen	Indicates that the contact has been made by a designated pointing device (e.g. a pen) instead of a finger.
QTouchEvent.TouchPoint.Token	Indicates that the contact has been made by a fiducial object (e.g. a knob or other token) instead of a finger.

PySide2.QtGui.QTouchEvent.TouchPoint. ellipseDiameters ( ) ¶

返回类型

QSizeF

Returns the width and height of the bounding ellipse of this touch point. The return value is in logical pixels. Most touchscreens do not detect the shape of the contact point, so a null size is the most common value. In other cases the diameters may be nonzero and equal (the ellipse is approximated as a circle).

PySide2.QtGui.QTouchEvent.TouchPoint. flags ( ) ¶

返回类型

InfoFlags

Returns additional information about the touch point.

InfoFlags

PySide2.QtGui.QTouchEvent.TouchPoint. id ( ) ¶

返回类型

int

Returns the id number of this touch point.

Do not assume that id numbers start at zero or that they are sequential. Such an assumption is often false due to the way the underlying drivers work.

PySide2.QtGui.QTouchEvent.TouchPoint. lastNormalizedPos ( ) ¶

返回类型

QPointF

Returns the normalized position of this touch point from the previous touch event.

The coordinates are normalized to the size of the touch device, i.e. (0,0) is the top-left corner and (1,1) is the bottom-right corner.

normalizedPos() startNormalizedPos()

PySide2.QtGui.QTouchEvent.TouchPoint. lastPos ( ) ¶

返回类型

QPointF

Returns the position of this touch point from the previous touch event, relative to the widget or QGraphicsItem that received the event.

pos() startPos()

PySide2.QtGui.QTouchEvent.TouchPoint. lastScenePos ( ) ¶

返回类型

QPointF

Returns the scene position of this touch point from the previous touch event.

The scene position is the position in QGraphicsScene coordinates if the QTouchEvent is handled by a QGraphicsItem::touchEvent() reimplementation, and identical to the screen position for widgets.

PySide2.QtGui.QTouchEvent.TouchPoint. lastScreenPos ( ) ¶

返回类型

QPointF

Returns the screen position of this touch point from the previous touch event.

PySide2.QtGui.QTouchEvent.TouchPoint. normalizedPos ( ) ¶

返回类型

PySide2.QtGui.QTouchEvent.TouchPoint. pressure ( ) ¶

返回类型

qreal

Returns the pressure of this touch point. The return value is in the range 0.0 to 1.0.

PySide2.QtGui.QTouchEvent.TouchPoint. rawScreenPositions ( ) ¶

返回类型

Returns the raw, unfiltered positions for the touch point. The positions are in native screen coordinates. To get local coordinates you can use mapFromGlobal() of the QWindow returned by window() .

注意

Returns an empty vector if the touch device’s capabilities do not include RawPositions .

注意

Native screen coordinates refer to the native orientation of the screen which, in case of mobile devices, is typically portrait. This means that on systems capable of screen orientation changes the positions in this list will not reflect the current orientation (unlike pos() , screenPos() , etc.) and will always be reported in the native orientation.

PySide2.QtGui.QTouchEvent.TouchPoint. rect ( ) ¶

返回类型

QRectF

注意

此函数被弃用。

This function is deprecated since 5.9 because it returns the outer bounds of the touchpoint regardless of rotation, whereas a touchpoint is more correctly modeled as an ellipse at position pos() with ellipseDiameters() which are independent of rotation() .

PySide2.QtGui.QTouchEvent.TouchPoint. rotation ( ) ¶

返回类型

qreal

Returns the angular orientation of this touch point. The return value is in degrees, where zero (the default) indicates the finger or token is pointing upwards, a negative angle means it’s rotated to the left, and a positive angle means it’s rotated to the right. Most touchscreens do not detect rotation, so zero is the most common value.

PySide2.QtGui.QTouchEvent.TouchPoint. scenePos ( ) ¶

返回类型

QPointF

Returns the scene position of this touch point.

The scene position is the position in QGraphicsScene coordinates if the QTouchEvent is handled by a QGraphicsItem::touchEvent() reimplementation, and identical to the screen position for widgets.

PySide2.QtGui.QTouchEvent.TouchPoint. sceneRect ( ) ¶

返回类型

注意

此函数被弃用。

This function is deprecated since 5.9 because it returns the outer bounds of the touchpoint regardless of rotation, whereas a touchpoint is more correctly modeled as an ellipse at position scenePos() with ellipseDiameters() which are independent of rotation() .
