C++ (Cpp) data_lower_layer Examples

Example #1

File: layer_dialog.c Project: AmiGanguli/dia

static void
layer_change_revert(struct LayerChange *change, Diagram *dia)
{
  switch (change->type) {
  case TYPE_DELETE_LAYER:
    data_add_layer_at(dia->data, change->layer, change->index);
    break;
  case TYPE_ADD_LAYER:

    break;
  case TYPE_RAISE_LAYER:
    data_lower_layer(dia->data, change->layer);
    break;
  case TYPE_LOWER_LAYER:
    data_raise_layer(dia->data, change->layer);
    break;
  }

  diagram_add_update_all(dia);

  if (layer_dialog->diagram == dia) {
    layer_dialog_set_diagram(dia);
  }

  change->applied = 0;
}

Example #2

File: pydia-diagramdata.c Project: UIKit0/dia

static PyObject *

{
    PyDiaLayer *layer;

    if (!PyArg_ParseTuple(args, "O!:DiagramData.lower_layer",

	return NULL;
    data_lower_layer(self->data, layer->layer);
    Py_INCREF(Py_None);
    return Py_None;
}
