示例1: update
//! recreate html page if something changes
void MetadataItemPropertiesPanel::update()
{
Database* db = dynamic_cast<Database*>(objectM);
if (db && !db->isConnected())
{
objectM = 0;
if (MetadataItemPropertiesFrame* f = getParentFrame())
f->Close();
// MB: This code used to use:
//f->removePanel(this);
// which would allow us to mix property pages from different
// databases in the same Frame, but there are some mysterious
// reasons why it causes heap corruption with MSVC
return;
}
// if table or view columns change, we need to reattach
if (objectM->getType() == ntTable || objectM->getType() == ntView) // also observe columns
{
Relation* r = dynamic_cast<Relation*>(objectM);
if (!r)
return;
SubjectLocker locker(r);
r->ensureChildrenLoaded();
for (ColumnPtrs::iterator it = r->begin(); it != r->end(); ++it)
(*it)->attachObserver(this, false);
}
// if description of procedure params change, we need to reattach
if (objectM->getType() == ntProcedure)
{
Procedure* p = dynamic_cast<Procedure*>(objectM);
if (!p)
return;
SubjectLocker locker(p);
p->ensureChildrenLoaded();
for (ParameterPtrs::iterator it = p->begin(); it != p->end(); ++it)
(*it)->attachObserver(this, false);
}
// with this set to false updates to the same page do not show the
// "Please wait while the data is being loaded..." temporary page
// this results in less flicker, but may also seem less responsive
if (!htmlReloadRequestedM)
requestLoadPage(false);
