Detailed Description

Container that automatically resizes children to fit the entire available space between children.

The children are positioned side by side.

Member Function Documentation

◆ clone()

Widget::Ptr tgui::HorizontalLayout::clone ( ) const
inlineoverrideprotectedvirtual

Makes a copy of the widget if you don't know its exact type.

This function should only be used when you don't know the type of the widget. If you know what kind of widget you are copying, you should use the copy function.

Returns
Copy of the widget

Reimplemented from tgui::Group.

◆ copy()

static HorizontalLayout::Ptr tgui::HorizontalLayout::copy ( ConstPtr  layout)
static

Makes a copy of another layout.

Parameters
layoutThe other layout
Returns
The new layout

◆ create()

static HorizontalLayout::Ptr tgui::HorizontalLayout::create ( const Layout2d size = {"100%", "100%"})
static

Creates a new horizontal layout widget.

Parameters
sizeSize of the horizontal layout
Returns
The new horizontal layout

◆ updateWidgets()

void tgui::HorizontalLayout::updateWidgets ( )
overrideprotectedvirtual

Implements tgui::BoxLayout.
