Parameters
autoSizeShould the size of the label be changed when the text changes?

When the label is in auto-size mode, the width and height of the label will be changed to fit the text. Otherwise, only the part defined by the size will be visible.

The label is auto-sized by default.

◆ setHorizontalAlignment()

void tgui::Label::setHorizontalAlignment ( tgui::HorizontalAlignment alignment)

Changes the horizontal text alignment.

Parameters
alignmentThe new horizontal text alignment

By default the text is aligned to the left.

◆ setMaximumTextWidth()

void tgui::Label::setMaximumTextWidth ( float maximumWidth)

Changes the maximum width that the text will have when auto-sizing.

Parameters
maximumWidthThe new maximum text width

This property is ignored when an exact size has been given. Pass 0 to this function to disable the maximum.

When the text is auto-sizing then the text will be split over several lines when its width would exceed the value passed to this function.

◆ setParent()

void tgui::Label::setParent ( Container * parent)
overridevirtual

Reimplemented from tgui::Widget.

◆ setScrollbarPolicy()

void tgui::Label::setScrollbarPolicy ( Scrollbar::Policy policy)

Changes when the vertical scrollbar should be displayed.

Parameters
policyThe policy for displaying the vertical scrollbar

◆ setScrollbarValue()

void tgui::Label::setScrollbarValue ( unsigned int value)

Changes the thumb position of the scrollbar.

Parameters
valueNew value of the scrollbar

◆ setSize() [1/2]

void tgui::Label::setSize ( const Layout2d & size)
overridevirtual

Changes the area of the text that will be drawn.

Parameters
sizeSize of the part to draw

Only the part of the text that lies within the size will be drawn.

When a background color is set, the drawn background will have this size. So setting a size that is bigger than the text will result in a bigger area being filled.

When this function is called, the label will no longer be auto-sizing.
