Constructor & Destructor Documentation

◆ Label() [1/2]

fcn::Label::Label ( )

Definition at line 16 of file label.cpp.

◆ Label() [2/2]

fcn::Label::Label ( std::string caption )

explicit

Constructor.

The label will be automatically resized to fit the caption.

Parameters

caption The caption of the label.

Definition at line 21 of file label.cpp.

References adjustSizeImpl(), mAlignment, and mCaption.

Member Function Documentation

◆ adjustSize()

void fcn::Label::adjustSize ( )

overridevirtual

Resizes the widget's size to fit the content exactly.

Reimplemented from fcn::Widget.

Definition at line 54 of file label.cpp.

References adjustSizeImpl().

◆ adjustSizeImpl()

void fcn::Label::adjustSizeImpl ( )

protected

Adjusts the size of the label to fit the caption.

The public adjustSize() method serves as a virtual entry point for polymorphism, while this adjustSizeImpl() method contains the concrete implementation of the resizing logic.

See also: adjustSize (virtual entry point for polymorphism)

Definition at line 59 of file label.cpp.

Referenced by adjustSize(), Label(), resizeToContent(), and setCaption().

◆ draw()

void fcn::Label::draw ( Graphics * graphics )

overridevirtual

Draws the widget.

The call to draw is initiated by the widget's parent. The graphics object is set up so that all drawing is relative to the widget, i.e coordinate (0,0) is the top left corner of the widget. It is not possible to draw outside of a widget's dimension. If a widget has children, the parent's draw function will always be called before the children's draw functions are called.

NOTE: A widget with children won't draw its children unless the children area given by Widget::getChildrenArea returns a none empty rectangle inside the widgets dimension. The children area is considered relative to the widget's position.

Parameters

Graphics & Rendering A graphics object to draw with.

See also: getChildrenArea, drawOutline, drawBorder

Implements fcn::Widget.

Definition at line 66 of file label.cpp.

◆ getAlignment()

Graphics::Alignment fcn::Label::getAlignment ( ) const

Gets the alignment of the caption.

The alignment is relative to the center of the label.

Returns: The alignment of caption of the label.

See also: setAlignment Graphics

Definition at line 42 of file label.cpp.

References mAlignment.

Referenced by draw().

◆ getCaption()

std::string const & fcn::Label::getCaption ( ) const

Gets the caption of the label.

Returns: The caption of the label.

See also: setCaption

Definition at line 26 of file label.cpp.

References mCaption.

Referenced by draw().

◆ resizeToContent() [1/2]

void fcn::Widget::resizeToContent ( )

inline

Resizes the widget's size to fit the content exactly, calls recursively all childs.

This is a convenience wrapper that calls resizeToContent(true).

Definition at line 1417 of file widget.hpp.

◆ resizeToContent() [2/2]

void fcn::Label::resizeToContent ( bool recursion )

overridevirtual

Resize this widget to fit its content.

Parameters

recursion If true, perform the resize operation recursively on children.

Reimplemented from fcn::Widget.

Definition at line 47 of file label.cpp.

References adjustSizeImpl().

◆ setAlignment()

void fcn::Label::setAlignment ( Graphics::Alignment alignment )

Sets the alignment of the caption.

The alignment is relative to the center of the label.

Parameters

alignment The alignment of the caption of the label.

See also: getAlignment, Graphics

Definition at line 37 of file label.cpp.

References mAlignment.

◆ setCaption()

void fcn::Label::setCaption ( std::string const & caption )

Sets the caption of the label.

It's advisable to call adjustSize after setting of the caption to adjust the label's size to fit the caption.

Parameters

caption The caption of the label.

See also: getCaption, adjustSize

Definition at line 31 of file label.cpp.

References adjustSizeImpl(), and mCaption.

protected

Holds the caption of the label.
