Detailed Description

Displays a text caption.

Definition at line 25 of file label.hpp.

Constructor & Destructor Documentation

◆ Label() [1/2]

fcn::Label::Label ( )

Definition at line 22 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
captionThe caption of the label.

Definition at line 27 of file label.cpp.

References adjustSizeImpl(), 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 70 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)

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
graphicsA graphics object to draw with.

getChildrenArea, drawOutline, drawBorder

◆ 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.

◆ getCaption()

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

Gets the caption of the label.

Returns
The caption of the label.

setCaption

◆ getVerticalAlignment()

Graphics::VerticalAlignment fcn::Label::getVerticalAlignment ( ) const

Gets the vertical alignment of the caption.

Returns
The vertical alignment of the caption.
See also
setVerticalAlignment

Definition at line 58 of file label.cpp.

References mVerticalAlignment.

◆ resizeToContent()

void fcn::Label::resizeToContent ( bool recursion = true)
overridevirtual

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

The default value true allows callers to use resizeToContent() without argument.

Parameters
recursionIf true, perform the resize operation recursively on children.

Reimplemented from fcn::Widget.

Definition at line 63 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
alignmentThe alignment of the caption of the label.
See also
getAlignment, Graphics

Definition at line 43 of file label.cpp.

References mAlignment.

◆ setCaption()

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

Sets the caption of the label.

After updating the caption, call adjustSize() to ensure the label resizes to fit the new content.

Parameters
captionThe caption of the label.
See also
getCaption, adjustSize

Definition at line 37 of file label.cpp.

References adjustSizeImpl(), and mCaption.

◆ setVerticalAlignment()

void fcn::Label::setVerticalAlignment ( Graphics::VerticalAlignment alignment)

Sets the vertical alignment of the caption.

Parameters
alignmentThe vertical alignment of the caption.
See also
getVerticalAlignment

Definition at line 53 of file label.cpp.

References mVerticalAlignment.
