Detailed Description#

A QPaintedTextureImage provides a way to specify a texture image (and thus an OpenGL texture) through a QPainter. The width and height of the texture image can be specified through the width and height or size properties.

A QPaintedTextureImage must be subclassed and the virtual paint() function implemented. Each time update() is called on the QPaintedTextureImage , the paint() function is invoked and the resulting image is uploaded.

The QPaintedTextureImage must be attached to some QAbstractTexture .

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property heightᅟ: int#

This property holds the height of the texture image. The height must be greater than or equal to 1.

Access functions:

height()
setHeight()
Signal heightChanged()

property sizeᅟ: QSize#

This property holds the size of the texture image.

See also

height width

Access functions:

size()
setSize()
Signal sizeChanged()

property widthᅟ: int#

This property holds the width of the texture image. The width must be greater than or equal to 1.

Access functions:

width()
setWidth()
Signal widthChanged()

__init__([parent=None])#

Parameters:: parent – QNode

height()#

Return type:: int

See also

setHeight()

Getter of property heightᅟ .

heightChanged(w)#

Parameters:: w – int

Notification signal of property heightᅟ .

abstract paint(painter)#

Parameters:: painter – QPainter

Paints the texture image with the specified QPainter object painter.

QPainter considers the top-left corner of an image as its origin, while OpenGL considers the bottom-left corner of a texture as its origin. An easy way to account for this difference is to set a custom viewport on the painter before doing any other painting:

painter->setViewport(0, height(), width(), -height());
...

setHeight(h)#

Parameters:: h – int

Sets the height (h) of the texture image. Triggers an update, if the size changes.

See also

height()

Setter of property heightᅟ .

setSize(size)#

Parameters:: size – QSize

Sets the width and height of the texture image. Triggers an update, if the size changes.

See also

size()

Setter of property sizeᅟ .

setWidth(w)#

Parameters:: w – int

Sets the width (w) of the texture image. Triggers an update, if the size changes.

See also

width()

Setter of property widthᅟ .

size()#

Return type:: QSize
