Member Function Documentation

bool SimShell::Gui::HasUnsavedChangesPrompt::PromptClose ( QWidget * parent = nullptr )

Display dialog window containing a list (or tree) of widgets that contain unsaved changes.

The user can select which widgets to save and which to discard, or to cancel the close operation. If there are no unsaved changes (in this widget and in its children), then no dialog is displayed and the method immediately returns true.

Returns: Whether we are in unopened state, i.e. close operation was successful (regardless whether user saved or discarded changes)
