Member Function Documentation

void gcp::WidgetData::ClearSelection (  )  [inline]

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

Definition at line 173 of file widgetdata.h.

References SelectedObjects.

void gcp::WidgetData::Copy ( GtkClipboard *  clipboard  ) 

Parameters:
clipboard a GtkClipboard.
Copies the current selection to the clipboard.

void gcp::WidgetData::GetObjectBounds ( gcu::Object const *  obj,
gccv::Rect rect 
) const

Parameters:
obj a gcu::Object.
rect an ArtDRect which will receive the object bounds.
Gets the object bounds in canvas coordinates.

void gcp::WidgetData::GetSelectionBounds ( gccv::Rect rect  )  const

Parameters:
rect an ArtDRect which will receive the selection bounds.
Gets the selection bounds in canvas coordinates.

static xmlDocPtr gcp::WidgetData::GetXmlDoc ( GtkClipboard *  clipboard  )  [static]

Parameters:
clipboard a 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 189 of file widgetdata.h.

References SelectedObjects.

bool gcp::WidgetData::IsSelected ( gcu::Object const *  obj  )  const

Parameters:
obj an object.
Returns:
true if the object is selected, false otherwise.

void gcp::WidgetData::MoveSelectedItems ( double  dx,
double  dy 
)

Parameters:
dx the x coordinate of the translation vector.
dy the 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:
dx the x coordinate of the translation vector.
dy the 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:
x the x coordinate of the rotation center.
y the y coordinate of the rotation center.
angle the 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:
obj the object to select.
state the new selection state.
Selects the specified object.

void gcp::WidgetData::ShowSelection ( bool  state  ) 

Parameters:
state whether 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::Unselect ( gcu::Object obj  ) 

Parameters:
obj the object to unselect.
Unselects a specified object.

void gcp::WidgetData::UnselectAll (  ) 

Unselects everything.
