How do you notify an app that the active document is closed ?
Problem statement:
My app is currently listening to a state updater event:
SBSimulatorEvent::StateUpdateEnd
but when I close the document my app is not notified and tries to address some elements that are not anymore in the datagraph and therefore crash...
Hi Clement,
To listen to the document closed signal I connect my nodes to a custom signal like this:
SB_FOR(SBNode* node, atomIndexer) node->connectBaseSignalToSlot(this, SB_SLOT(&SENormalModesAnalysisApp::onBaseEvent));
Then, in my onBaseEvent function I catch the NodeEraseBegin event which corresponds to the signal emitted when the document is closed or the nodes erased.
void SENormalModesAnalysisApp::onBaseEvent(SBBaseEvent* event) {
if (event->getType() == SBBaseEvent::NodeEraseBegin) {
//disconnet the connected nodes
SB_FOR(SBNode* node, atomIndexer)
{node->disconnectBaseSignalFromSlot(this, SB_SLOT(&SENormalModesAnalysisApp::onBaseEvent));
}
//....//
}
Remember to disconnect the connected nodes.
Hope I answered your question,
