Member Function Documentation

draw()

void tt::label_stencil::draw ( draw_context context, tt::color color, matrix3 transform = geo::identity{} )

inlineoverridevirtualnoexcept

Draw the cell.

Parameters

context	The current draw context.
color	The color to use for drawing.

Implements tt::stencil.

preferred_extent()

extent2 tt::label_stencil::preferred_extent ( )

inlineoverridevirtualnoexcept

Return the extent that this cell wants to be drawn as.

Reimplemented from tt::stencil.

set_layout_parameters()

void tt::label_stencil::set_layout_parameters ( aarectangle const & rectangle, float base_line_position = std::numeric_limits<float>::infinity() )

inlineoverridevirtualnoexcept

Pass layout parameters in local coordinates.

Parameters

rectangle	The rectangle the stencil will be drawn into.
base_line_position	The position of the base line within the rectangle.

Reimplemented from tt::stencil.

set_show_icon()

void tt::label_stencil::set_show_icon ( bool flag )

inlinenoexcept

Set the show_icon() flag.

show_icon()

bool tt::label_stencil::show_icon ( ) const

inlinenoexcept

Whether the text in the label will align to an optional icon in the label.

Make space for, and optionally display, an icon in front of the text. This option should be used when any of the labels in a menu has an icon.

This should not be used when a menu is displayed in the same direction as the icon label. For example a left or right aligned menu item in a row menu; such as the tool-bar.

Return values

true	The text of the label will be aligned after an optional icon of the label.
false	The text of the label will be not be aligned to an optional icon of the label.
