示例1: updateChildComponents
void ComponentBuilder::updateChildComponents (Component& parent, const ValueTree& children)
{
using namespace ComponentBuilderHelpers;
const int numExistingChildComps = parent.getNumChildComponents();
Array <Component*> componentsInOrder;
componentsInOrder.ensureStorageAllocated (numExistingChildComps);
{
OwnedArray<Component> existingComponents;
existingComponents.ensureStorageAllocated (numExistingChildComps);
int i;
for (i = 0; i < numExistingChildComps; ++i)
existingComponents.add (parent.getChildComponent (i));
const int newNumChildren = children.getNumChildren();
for (i = 0; i < newNumChildren; ++i)
{
const ValueTree childState (children.getChild (i));
ComponentBuilder::TypeHandler* const type = getHandlerForState (childState);
jassert (type != nullptr);
if (type != nullptr)
{
Component* c = findComponentWithID (existingComponents, getStateId (childState));
if (c == nullptr)
c = createNewComponent (*type, childState, &parent);
componentsInOrder.add (c);
}
}
// (remaining unused items in existingComponents get deleted here as it goes out of scope)
}
// Make sure the z-order is correct..
