Detailed Description

A toolbar widget is located at the top of a window and lays out its children horizontally.

The toolbar widget is shown at the top of a window, it is drawn with a different background than the window's content to differentiate from it.

Child widgets may be added on both the left side and right side of the toolbar, a small space in the center is added for visual separation.

Child widgets are drawn to full height of the toolbar determined by the preferred size of all contained widgets. The width of each widget is determined by their preferred size

toolbar_widget()

hi::v1::toolbar_widget::toolbar_widget ( widget * parent )

noexcept

Constructs an empty row/column widget.

Parameters

parent

The parent widget.

Member Function Documentation

make_widget()

template<typename Widget , horizontal_alignment Alignment = horizontal_alignment::left, typename... Args>

Widget & hi::v1::toolbar_widget::make_widget ( Args &&... args )

inline

Add a widget directly to this toolbar-widget.

When Alignment is horizontal_alignment::left the new widget is added to the right of the previous added widget on the left side of the toolbar.

When Alignment is horizontal_alignment::right the new widget is added to the left of the previous added widget on the right side of the toolbar.

Template Parameters

Widget	The type of the widget to be constructed.
Alignment	Add widgets to the left, or right.

Parameters

args	The arguments passed to the constructor of the widget.

Returns

A reference to the widget that was created.
