How to know document panel is closed

6 months 3 weeks ago #1 by Liping Liu (Co Wheels Technology Co., Ltd.)
How to know document panel is closed was created by Liping Liu (Co Wheels Technology Co., Ltd.)
I am using DockPanelManager class to develop multi-document application (QtitanComponentsInstaller2023.1.0_PySide2_Qt5.15.2Win_x64).
I create a new document panel by using insertDocumentPanel API.

Now I have a question:
How I can receive a notice or event when an opend panel is closed?

To track changes in the panel state during operation, use these signals:

void DockPanelManager::aboutToShow(DockPanelBase* panel, bool& handled);
void DockPanelManager::aboutToClose(DockPanelBase* panel, bool& handled);
void DockPanelManager::aboutToAutoHide(DockPanelBase* panel, bool& handled);
void DockPanelManager::aboutToFloat(DockPanelBase* panel, bool& handled);

void DockPanelManager::dockPanelActivated(DockWidgetPanel* panel);
void DockPanelManager::dockPanelDeactivated(DockWidgetPanel* panel);

Additionally, you can listen QCloseEvent from the panel.
