詳細描述

A QAbstractTextureImage that can be written through a QPainter .

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 ， paint () function is invoked and the resulting image is uploaded.

The QPaintedTextureImage must be attached to some QAbstractTexture .

QPaintedTextureImage:: QPaintedTextureImage ( Qt3DCore::QNode * parent = nullptr)

Default constructs an instance of QPaintedTextureImage.

[虛擬] QPaintedTextureImage:: ~QPaintedTextureImage ()

Destroys the instance of QPaintedTextureImage. The destructor is virtual.

[pure virtual protected] void QPaintedTextureImage:: paint ( QPainter * painter )

Paints the texture image with the specified QPainter 對象 painter .

[slot] void QPaintedTextureImage:: setHeight ( int h )

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

注意： setter 函數對於特性 height .

另請參閱 height ().

[slot] void QPaintedTextureImage:: setSize ( QSize size )

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

注意： setter 函數對於特性 size .

另請參閱 size ().

[slot] void QPaintedTextureImage:: setWidth ( int w )

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

注意： setter 函數對於特性 width .

另請參閱 width ().

void QPaintedTextureImage:: update (const QRect & rect = QRect())

Schedules the painted texture's paint () function to be called, which in turn uploads the new image to the GPU. Parameter rect is currently unused.
