OEHighlightLabel¶

class OEHighlightLabel

The OEHighlightLabel class allows the customization the style of the label that can be position on molecule depiction by calling the OEAddLabel function.

The OEHighlightLabel class stores the following properties:

Property	Get method	Set method	Corresponding namespace / class / type
text	`GetText`	`OEHighlightLabel constructors`	string
bounding box pen	`GetBoundingBoxPen`	`SetBoundingBoxPen`	OEPen
label font	`GetFont`	`SetFont`	OEFont
label font scale	`GetFontScale`	`SetFontScale`	positive floating point number in the range of `[0.25, 1.5]` or `0.0`

Constructors¶

OEHighlightLabel(const std::string &text)

Creates an OEHighlightLabel object with default style.

text: The text that is going to be positioned on the molecule depiction.

Example:

OEHighlightLabel label = new OEHighlightLabel("match");

Example of adding label with default style¶

OEHighlightLabel(const std::string &text, const OEFont &font)

Creates an OEHighlightLabel object with user-defined font.

text: The text that is going to be positioned on the molecule depiction.
font: The OEFont object that encapsulates properties that determine the display style of text.

Example:

OEFont font = new OEFont(OEFontFamily.Courier, OEFontStyle.Bold, 12,
                             OEAlignment.Center, oechem.getOEDarkRed());
OEHighlightLabel label = new OEHighlightLabel("match", font);

Example of adding label with user-defined font¶

OEHighlightLabel(const std::string &text, const OESystem::OEColor &color)

Creates an OEHighlightLabel object with user-defined border color.

text: The text that is going to be positioned on the molecule depiction.
color: The color of the border around the label.

GetBoundingBoxPen¶

const OEPen &GetBoundingBoxPen() const

Returns the pen that is used to draw a border around the label.

SetBoundingBoxPen method

GetFont¶

const OEFont &GetFont() const

Returns the font of the label.

OEHighlightLabel.SetFont method

GetFontScale¶

double GetFontScale() const

Returns the multiplier that can be used to increase or decrease the font size of the label relative to the font size used to render labels of the of the depicted molecule. The default value is 0.75.

OEHighlightLabel.SetFontScale method

GetText¶

std::string GetText() const

Returns the text of the label.

SetBoundingBoxPen¶

void SetBoundingBoxPen(const OEPen &pen)

Sets the pen that is used to draw a border around the label.

Example:

OEHighlightLabel label = new OEHighlightLabel("match");
OEPen pen = new OEPen(new OEColor(255, 220, 220), oechem.getOEDarkRed(), OEFill.On, 16.0, OEStipple.ShortDash);
label.SetBoundingBoxPen(pen);

SetFont¶

void SetFont(const OEFont &font)

Set the font of the label.

Example:

OEHighlightLabel label = new OEHighlightLabel("match");
OEFont font = new OEFont(OEFontFamily.Default, OEFontStyle.Default, 12,
                             OEAlignment.Center, oechem.getOEDarkRed());
label.SetFont(font);

Example of adding label with user-defined font¶

Note

The size of fonts of the label depends on:

the size of the font used to render atom labels of the the depicted molecule
the multiplier set by the OEHighlightLabel.SetFontScale method

OEFont class

SetFontScale¶

void SetFontScale(double scale)

Sets the multiplier that can be used to increase or decrease the font size of the label relative to the font size used to render atom labels of the of the depicted molecule.

scale

This value has to be either 0.0 or in a range of [0.25, 1.50]. The default value is 0.75.

In case of 0.0, the label is not scaled with the molecule but rather fixed font size is used regardless of the size of the depicted molecule.

Example:

OEHighlightLabel label = new OEHighlightLabel("match");
label.SetFontScale(1.2);
