void Goocanvas::ItemSimple::changed | ( | bool | recompute_bounds | ) |
This function is intended to be used by subclasses of Goo::CanvasItemSimple.
It is used as a callback for the "changed" signal of the item models. It requests an update or redraw of the item as appropriate.
- Parameters
-
recompute_bounds If the item's bounds need to be recomputed.
bool Goocanvas::ItemSimple::check_in_path | ( | double | x, |
double | y, | ||
const Cairo::RefPtr< Cairo::Context > & | cr, | ||
PointerEvents | pointer_events | ||
) | const |
This function is intended to be used by subclasses of Goo::CanvasItemSimple.
It checks if the given point is in the current path, using the item's style settings.
- Parameters
-
x The x coordinate of the point. y The y coordinate of the point. cr A cairo context. pointer_events Specifies which parts of the path to check.
- Returns
true
if the given point is in the current path.
void Goocanvas::ItemSimple::check_style | ( | ) |
This function is intended to be used by subclasses of Goo::CanvasItemSimple, typically in their update() or get_requested_area() methods.
It ensures that the item's style is setup correctly. If the item has its own Goo::CanvasStyle it makes sure the parent is set correctly. If it doesn't have its own style it uses the parent item's style.
double Goocanvas::ItemSimple::get_line_width | ( | ) | const |
Gets the item's line width.
- Returns
- The item's line width.

void Goocanvas::ItemSimple::get_path_bounds | ( | const Cairo::RefPtr< Cairo::Context > & | context, |
Bounds& | bounds | ||
) | const |
This function is intended to be used by subclasses of Goo::CanvasItemSimple, typically in their update() or get_requested_area() methods.
It calculates the bounds of the current path, using the item's style settings, and stores the results in the given Goo::CanvasBounds struct.
The returned bounds contains the bounding box of the path in device space, converted to user space coordinates. To calculate the bounds completely in user space, use cairo_identity_matrix() to temporarily reset the current transformation matrix to the identity matrix.
- Parameters
-
context A cairo context. bounds The Goo::CanvasBounds struct to store the resulting bounding box.
