{
int MultiCurve = viewer->GetPlotIndex("MultiCurve");
AttributeSubject *atts = viewer->DelayedState()->GetPlotAttributes(MultiCurve);
if(atts != 0)
{
DataNode root("root");
atts->CreateNode(&root, true, false);
DataNode *multiCurveNode = root.GetNode("MultiCurveAttributes");
DataNode *singleColorNode = multiCurveNode->GetNode("singleColor");
DataNode *colorAttributeNode = singleColorNode->GetNode("ColorAttribute");
DataNode *colorNode = colorAttributeNode->GetNode("color");
const unsigned char *oldColor = colorNode->AsUnsignedCharArray();
unsigned char newColor[4];
newColor[0] = oldColor[0];
newColor[1] = oldColor[1];
newColor[2] = oldColor[2];
newColor[3] = (unsigned char)opacity;
DataNode *newColorNode = new DataNode("color", newColor, 4);
colorAttributeNode->RemoveNode(colorNode);
colorAttributeNode->AddNode(newColorNode);
atts->SetFromNode(&root);
atts->Notify();
emit multiCurveChanged(atts);
}
}示例2:
void
QvisLegacyStreamlinePlotWindow::ProcessOldVersions(DataNode *parentNode,
const char *configVersion)
{
if(parentNode == 0)
return;
DataNode *searchNode = parentNode->GetNode("Streamline plot attributes");
if(searchNode == 0)
return;
// Remove height/width information if the config file is older than
// 1.4.1 since this window changed size quite a bit in version 1.4.1.
if (LegacyStreamlineAttributes::VersionLessThan(configVersion, "1.4.1"))
{
searchNode->RemoveNode("width");
searchNode->RemoveNode("height");
}
