All Implemented Interfaces:

Direct Known Subclasses:

ListItemWidget

public class LabelWidget
extends Widget

A widget representing a text. The widget is not opaque and is checking clipping for by default.

It allows to set 4 types of horizontal and vertical alignments (by default LEFT as horizontal and BASELINE as vertical).

Swing Font-hinting feature may cause the labels are not rendered completely. Using setUseGlyphVector you may force the label to be converted to a glyph vector which scales correctly for any zoom factor.

Constructor Details

LabelWidget

public LabelWidget(Scene scene)

Creates a label widget.

Parameters:

scene - the scene

public LabelWidget(Scene scene,
 String label)

Creates a label widget with a label.

Parameters:

scene - the scene

label - the label

Method Details

getLabel

public String getLabel()

Returns a label.

Returns:

the label

setLabel

public void setLabel(String label)

Sets a label.

Parameters:

label - the label

getAlignment

public LabelWidget.Alignment getAlignment()

Returns a text horizontal alignment.

Returns:

the text horizontal alignment

setAlignment

public void setAlignment(LabelWidget.Alignment alignment)

Sets a text horizontal alignment.

Parameters:

alignment - the text horizontal alignment

getVerticalAlignment

public LabelWidget.VerticalAlignment getVerticalAlignment()

Gets a text vertical alignment.

Returns:

the text vertical alignment

setVerticalAlignment

public void setVerticalAlignment(LabelWidget.VerticalAlignment verticalAlignment)

Sets a text vertical alignment.

Parameters:

verticalAlignment - the text vertical alignment

getOrientation

public LabelWidget.Orientation getOrientation()

Gets a text orientation.

Returns:

the text orientation

Since:

2.1

setOrientation

public void setOrientation(LabelWidget.Orientation orientation)

Sets a text orientation.

Parameters:

orientation - the text orientation

Since:

2.1

isPaintAsDisabled

public boolean isPaintAsDisabled()

Returns whether the label is painted as disabled.

Returns:

true, if the label is painted as disabled

setPaintAsDisabled

public void setPaintAsDisabled(boolean paintAsDisabled)

Sets whether the label is painted as disabled.

Parameters:

paintAsDisabled - if true, then the label is painted as disabled

isUseGlyphVector

public boolean isUseGlyphVector()

Returns whether the label widget is using glyph vector for rendering text.

Returns:

true, if the label widget is using glyph vector

Since:

2.7

setUseGlyphVector

public void setUseGlyphVector(boolean useGlyphVector)

Sets whether the label widget is using glyph vector for rendering text.

Note that using glyph vector could slow-down the rendering performance. Note that if you are not using glyph vector then the text may be clipped when a scene has zoom factor different from 1.0.

Parameters:

useGlyphVector - if true, then a glyph vector is used for rendering text

Since:

2.7

calculateClientArea

protected Rectangle calculateClientArea()
