Member Function Documentation

bool gcp::WidgetData::ChildrenSelected ( gcu::Object const *  obj) const
Parameters:
objan object.
Returns:
true if all the object children are selected, false otherwise or if has no children.
void gcp::WidgetData::ClearSelection ( ) [inline]

Empties the set of selected objects. Called after objects have been deleted.

Definition at line 189 of file widgetdata.h.

References SelectedObjects.

void gcp::WidgetData::Copy ( GtkClipboard *  clipboard)
Parameters:
clipboarda GtkClipboard.

Copies the current selection to the clipboard.

void gcp::WidgetData::GetObjectBounds ( gcu::Object const *  obj,
gccv::Rect rect 
) const
Parameters:
obja gcu::Object.
rectan ArtDRect which will receive the object bounds.

Gets the object bounds in canvas coordinates.

void gcp::WidgetData::GetObjectsBounds ( std::set< gcu::Object const * > const &  objects,
gccv::Rect rect 
) const
Parameters:
objectsa set of gcu::Object.
rectan ArtDRect which will receive the object bounds.

Gets the object bounds in canvas coordinates.

gcu::Object* gcp::WidgetData::GetSelectedAncestor ( gcu::Object obj)
Parameters:
objan object.
Returns:
the topmost ancestor whose all children are selected, NULL if none or if the ancestor is the document.
void gcp::WidgetData::GetSelectionBounds ( gccv::Rect rect) const
Parameters:
rectan ArtDRect which will receive the selection bounds.

Gets the selection bounds in canvas coordinates.

static xmlDocPtr gcp::WidgetData::GetXmlDoc ( GtkClipboard *  clipboard) [static]
Parameters:
clipboarda GtkClipboard.
Returns:
the xmlDocPtr associtated with the clipboard.
bool gcp::WidgetData::HasSelection ( ) [inline]
Returns:
true if at least one object is selected, false otherwise.

Definition at line 205 of file widgetdata.h.

References SelectedObjects.

bool gcp::WidgetData::IsSelected ( gcu::Object const *  obj) const
Parameters:
objan object.
Returns:
true if the object is selected, false otherwise.
void gcp::WidgetData::MoveSelectedItems ( double  dx,
double  dy 
)
Parameters:
dxthe x coordinate of the translation vector.
dythe y coordinate of the translation vector.

Moves the items representing the selection, but don't move the objects themselves and don't modify the document. This is used by the selection tool but might be deprecated in the future.

void gcp::WidgetData::MoveSelection ( double  dx,
double  dy 
)
Parameters:
dxthe x coordinate of the translation vector.
dythe y coordinate of the translation vector.

Moves the selection. This method creates an Operation instance for the Undo/Redo framework.

void gcp::WidgetData::RotateSelection ( double  x,
double  y,
double  angle 
)
Parameters:
xthe x coordinate of the rotation center.
ythe y coordinate of the rotation center.
anglethe rotation angle.

Rotates the selection. This method does not create an Operation instance.

void gcp::WidgetData::SelectAll ( )

Selects the whole document.

void gcp::WidgetData::SetSelected ( gcu::Object obj,
int  state = gcp::SelStateSelected 
)
Parameters:
objthe object to select.
statethe new selection state.

Selects the specified object.

void gcp::WidgetData::ShowSelection ( bool  state)
Parameters:
statewhether to show or not the selection.

If state is true, the selection is highlighted, otherwise, it is displayed normally. This is used when printing or exporting an image.

void gcp::WidgetData::SimplifySelection ( )

Replace the selected objects by their parents if all parents children are selected.

void gcp::WidgetData::Unselect ( gcu::Object obj)
Parameters:
objthe object to unselect.

Unselects a specified object.

void gcp::WidgetData::UnselectAll ( )

Unselects everything.
