Description

Functions

cr_cascade_new ()

CRCascade *
cr_cascade_new (CRStyleSheet *a_author_sheet,
                CRStyleSheet *a_user_sheet,
                CRStyleSheet *a_ua_sheet);

Constructor of the CRCascade class. Note that all three parameters of this method are ref counted and their refcount is increased. Their refcount will be decreased at the destruction of the instance of CRCascade. So the caller should not call their destructor. The caller should call their ref/unref method instead if it wants

Returns the newly built instance of CRCascade or NULL if an error arose during constrution.

Parameters

a_author_sheet

the author origin style sheet. May be NULL.

 

a_user_sheet

the user origin style sheet. May be NULL.

 

a_ua_sheet

the user agent origin style sheet. May be NULL.

 

cr_cascade_get_sheet ()

CRStyleSheet *
cr_cascade_get_sheet (CRCascade *a_this,
                      enum CRStyleOrigin a_origin);

Gets a sheet, part of the cascade. Note that the returned stylesheet is refcounted so if the caller wants to manage it's lifecycle, it must use cr_stylesheet_ref()/cr_stylesheet_unref() instead of the cr_stylesheet_destroy() method. Returns the style sheet, or NULL if it does not exist.

Parameters

a_this

the current instance of CRCascade.

 

a_origin

the origin of the style sheet as defined in the css2 spec in chapter 6.4. Gets a given origin sheet.

 

cr_cascade_set_sheet ()

enum CRStatus
cr_cascade_set_sheet (CRCascade *a_this,
                      CRStyleSheet *a_sheet,
                      enum CRStyleOrigin a_origin);

Sets a stylesheet in the cascade

Parameters

a_this

the current instance of CRCascade.

 

a_sheet

the stylesheet to set.

 

a_origin

cr_cascade_ref ()

void
cr_cascade_ref (CRCascade *a_this);

Increases the reference counter of the current instance of CRCascade.

Parameters

a_this

the current instance of CRCascade

 

cr_cascade_unref ()

void
cr_cascade_unref (CRCascade *a_this);

Decrements the reference counter associated to this instance of CRCascade. If the reference counter reaches zero, the instance is destroyed using cr_cascade_destroy()

Parameters

a_this

the current instance of CRCascade.

 

cr_cascade_destroy ()

void
cr_cascade_destroy (CRCascade *a_this);

Destructor of CRCascade.

Parameters

a_this

the current instance of CRCascade
