Detailed Description

WidgetStack manages multiple widgets in a stack.

WidgetStack, like WidgetProxy, delegates at most one widget. Unlike WidgetProxy, it maintains multiple widgets. It saves all widgets pushed into by SetWidget and always shows the top one. The WidgetStack is a subclass of WidgetProxy, in another word, the topmost widget will delegate it self to WidgetStack. PopWidget will remove the topmost widget and callback set by SetOnTop taking the new topmost widget will be called. The WidgetStack disappears in GUI if there is no widget in stack.

Due to content and layout changing of the new widget, after SetWidget or PopWidget the relayout of Window might need be called.

Member Function Documentation

◆ PopWidget()

std::shared_ptr< Widget > open3d::visualization::gui::WidgetStack::PopWidget ( )

Pop the top most widget.

Due to content and layout changing of the new widget, the relayout of Window might need be called.

Parameters

widget Widget to push into stack to be topmost showing wiget.

Returns: widget is popped, or NULL if no widget in the stack.

◆ PushWidget()

void open3d::visualization::gui::WidgetStack::PushWidget ( std::shared_ptr< Widget > widget )

Push a widget into stack so the it be the topmost widget.

After a widget is pushed into stack, it will be shown in the GUI. Due to content and layout changing of the new widget, the relayout of Window might need be called.

Parameters

widget Widget to push into stack to be topmost showing wiget.

◆ SetOnTop()

void open3d::visualization::gui::WidgetStack::SetOnTop ( std::function< void(std::shared_ptr< Widget >)> onTopCallback )

Setup a callback while a widget is popped out and a new widget becomes the topmost one.

Parameter of callback will be the new topmost widget.

Parameters

onTopCallback Callback function taking the new topmost widget.
