QMatrix4x4:: QMatrix4x4 (const QMatrix & matrix )

此函數已過時。提供它是為使舊源代碼能繼續工作。強烈建議不要在新代碼中使用它。

Constructs a 4x4 matrix from a conventional Qt 2D affine transformation matrix .

若 matrix has a special type (identity, translate, scale, etc), the programmer should follow this constructor with a call to optimize () if they wish QMatrix4x4 to optimize further calls to translate (), scale ()，等。

另請參閱 toAffine () 和 optimize ().

void QMatrix4x4:: flipCoordinates ()

此函數已過時。提供它是為使舊源代碼能繼續工作。強烈建議不要在新代碼中使用它。

Flips between right-handed and left-handed coordinate systems by multiplying the y and z co-ordinates by -1. This is normally used to create a left-handed orthographic view without scaling the viewport as ortho () 所做的。

另請參閱 ortho ().

QMatrix QMatrix4x4:: toAffine () const

此函數已過時。提供它是為使舊源代碼能繼續工作。強烈建議不要在新代碼中使用它。

使用 toTransform () 代替。

Returns the conventional Qt 2D affine transformation matrix that corresponds to this matrix. It is assumed that this matrix only contains 2D affine transformation elements.

另請參閱 toTransform ().

template <int N, int M> QGenericMatrix < N , M , float > qGenericMatrixFromMatrix4x4 (const QMatrix4x4 & matrix )

此函數已過時。提供它是為使舊源代碼能繼續工作。強烈建議不要在新代碼中使用它。

Returns a NxM generic matrix constructed from the left-most N columns and top-most M rows of matrix . If N or M is greater than 4, then the remaining elements are filled with elements from the identity matrix.

另請參閱 QMatrix4x4::toGenericMatrix ().

template <int N, int M> QMatrix4x4 qGenericMatrixToMatrix4x4 (const QGenericMatrix < N , M , float > & matrix = N)

此函數已過時。提供它是為使舊源代碼能繼續工作。強烈建議不要在新代碼中使用它。

Returns a 4x4 matrix constructed from the left-most 4 columns and top-most 4 rows of matrix 。若 matrix has less than 4 columns or rows, the remaining elements are filled with elements from the identity matrix.
