Detailed Description

Class that encapsulates information for a text component.

Member Function Documentation

const String& CEGUI::TextComponent::getFont ( ) const

Return the name of the font set to be used when rendering this TextComponent.

Note
This returns the name of the font set directly to the TextComponent, which may or may not be the actual font that will be used - since the actual font may be sourced from a property or the main font setting on a window that the TextComponent is rendered to, or the default font. To get the actual font name that will be used, call the getEffectiveFont function instead.
Returns
String object containing the name of a font
const String& CEGUI::TextComponent::getFontPropertySource ( ) const

Return the name of the property that will be used to determine the font to use for rendering the text string for this TextComponent.

Returns
String object holding the name of a Propery.
HorizontalTextFormatting CEGUI::TextComponent::getHorizontalFormatting ( const Window wnd) const

Return the current horizontal formatting setting for this TextComponent.

Returns
One of the HorizontalTextFormatting enumerated values.
const String& CEGUI::TextComponent::getText ( ) const

Return the text set for this TextComponent.

Note
This returns the text string set directly to the TextComponent, which may or may not be the actual string that will be used - since the actual string may be sourced from a property or the main text string from a window that the TextComponent is rendered to. To get the actual string, call the getEffectiveText function instead.
const String& CEGUI::TextComponent::getTextPropertySource ( ) const

Return the name of the property that will be used to determine the text string to render for this TextComponent.

Returns
String object holding the name of a Propery.
const String& CEGUI::TextComponent::getTextVisual ( ) const

return text string with visual ordering of glyphs.

Note
This returns the visual text derived from the string set directly to the TextComponent, which may or may not be the actual string that will be used - since the actual string may be sourced from a property or the main text string from a window that the TextComponent is rendered to. To get the actual visual string, call the getEffectiveVisualText function instead.
VerticalTextFormatting CEGUI::TextComponent::getVerticalFormatting ( const Window wnd) const

Return the current vertical formatting setting for this TextComponent.

Returns
One of the VerticalTextFormatting enumerated values.
bool CEGUI::TextComponent::isFontFetchedFromProperty ( ) const

Return whether this TextComponent fetches it's font via a property on the target window.

Returns
  • true if the font comes via a Propery.
  • false if the font is defined explicitly, or will come from the target window.
bool CEGUI::TextComponent::isTextFetchedFromProperty ( ) const

Return whether this TextComponent fetches it's text string via a property on the target window.

Returns
  • true if the text string comes via a Propery.
  • false if the text string is defined explicitly, or will come from the target window.
void CEGUI::TextComponent::setFont ( const String font)

Set the name of a font to be used when rendering this TextComponent.

Note
Setting this may not set the actual font that will be used when rendering the TextComponent. The acutal font used will depend upon whether a font source property is set and whether the font name set here is set to the empty string or not.
Parameters
fontString containing name of a font
void CEGUI::TextComponent::setFontPropertySource ( const String property)

Set the name of the property that will be used to determine the font to use for rendering the text string of this TextComponent.

Parameters
propertyString object holding the name of a Propery. The property should access a valid font name.
Returns
Nothing.
void CEGUI::TextComponent::setHorizontalFormatting ( HorizontalTextFormatting  fmt)

Set the horizontal formatting setting for this TextComponent.

Parameters
fmtOne of the HorizontalTextFormatting enumerated values.
Returns
Nothing.
void CEGUI::TextComponent::setText ( const String text)

Set the text string for this TextComponent.

Note
Setting this string may not set the actual string that will be used when rendering the TextComponent. The acutal string used will depend upon whether a text source property is set and whether this string is set to the empty string or not.
Parameters
textString containing text to set on the TextComponent.
void CEGUI::TextComponent::setTextPropertySource ( const String property)

Set the name of the property that will be used to determine the text string to render for this TextComponent.

Parameters
propertyString object holding the name of a Propery. The property can contain any text string to render.
Returns
Nothing.
void CEGUI::TextComponent::setVerticalFormatting ( VerticalTextFormatting  fmt)

Set the vertical formatting setting for this TextComponent.

Parameters
fmtOne of the VerticalTextFormatting enumerated values.
Returns
Nothing.
void CEGUI::TextComponent::writeXMLToStream ( XMLSerializer xml_stream) const

Writes an xml representation of this TextComponent to out_stream.

Parameters
xml_streamStream where xml data should be output.
Returns
Nothing.
