Public Member Functions
QSize	minimumSizeHint () const override
	Returns the minimum recommended size for the label. Similar to sizeHint, but based on the minimum text size.
void	SetShapeColor (const QColor &color)
	Sets the color of the circle and its glow. Triggers a repaint of the label.
QSize	sizeHint () const override
	Returns the recommended size for the label. Calculates the size based on the text size plus the space required for the colored circle, its glow, and padding.
	UserInfoLabel (QWidget *parent=nullptr)
	Constructs a UserInfoLabel. Initializes default parameters for the circle and glow effect (diameter, pen width, glow layers, spread) and calculates the total space required for the shape.

Protected Member Functions
void	paintEvent (QPaintEvent *event) override
	Overridden paint event handler. Draws the custom label appearance. Renders the background, the colored circle with its multi-layered glow effect, and finally the label text positioned to the right of the shape.

Private Attributes
int	circle_diameter_
	Diameter of the main colored circle indicator.
int	glow_layers_
	Number of layers used to render the glow effect.

	How much each glow layer expands outwards relatively to the previous one.
qreal	pen_width_
	The thickness of the pen used to draw the main circle.
QColor	shape_color_
	The base color used for the circle and its glow.
int	shape_padding_
	Horizontal padding between the right edge of the glow and the start of the text.

	Pre-calculated total width required for the circle and its maximum glow extent.

Detailed Description

A custom QLabel that displays text alongside a colored circle with a glow effect.

This label is designed to show user information (like a username) preceded by a visual indicator (a colored circle). The circle's color can be set using SetShapeColor, and it features a multi-layered glow effect rendered in the paintEvent. The size hint is adjusted to accommodate the circle and its glow.

Returns the minimum recommended size for the label. Similar to sizeHint, but based on the minimum text size.

Returns

The calculated minimum QSize hint.

paintEvent()

void UserInfoLabel::paintEvent ( QPaintEvent * event )

Overridden paint event handler. Draws the custom label appearance. Renders the background, the colored circle with its multi-layered glow effect, and finally the label text positioned to the right of the shape.

Parameters

event

The paint event.

SetShapeColor()

void UserInfoLabel::SetShapeColor

const QColor &

color

)

Sets the color of the circle and its glow. Triggers a repaint of the label.

Parameters

color

The desired QColor for the shape.

sizeHint()

QSize UserInfoLabel::sizeHint ( ) const

override

Returns the recommended size for the label. Calculates the size based on the text size plus the space required for the colored circle, its glow, and padding.

Returns

The calculated QSize hint.
