Detailed Description

Editbox class for the FalagardBase module.

This class requires LookNFeel to be assigned. The LookNFeel should provide the following:

States:

Enabled: Rendering for when the editbox is in enabled and is in read-write mode.
ReadOnly: Rendering for when the editbox is in enabled and is in read-only mode.
Disabled: Rendering for when the editbox is disabled.
ActiveSelection: additional state rendered for text selection (the imagery in this section is rendered within the selection area.)
InactiveSelection: additional state rendered for text selection (the imagery in this section is rendered within the selection area.)

NamedAreas:

TextArea: area where text, selection, and caret imagery will appear.

PropertyDefinitions (optional)

NormalTextColour: property that accesses a colour value to be used to render normal unselected text. If this property is not defined, the colour defaults to black.
SelectedTextColour: property that accesses a colour value to be used to render selected text. If this property is not defined, the colour defaults to black.

Imagery Sections:

Caret

Member Function Documentation

size_t CEGUI::FalagardEditbox::getTextIndexFromPosition ( const Vector2f & pt ) const

virtual

Return the text code point index that is rendered closest to screen position pt.

Parameters

pt	Point object describing a position on the screen in pixels.

Returns: Code point index into the text that is rendered closest to screen position pt.

Implements CEGUI::EditboxWindowRenderer.

bool CEGUI::FalagardEditbox::handleFontRenderSizeChange ( const Font *const font )

virtual

Perform any updates needed because the given font's render size has changed.

/note This base implementation deals with updates needed for various definitions in the assigned widget look. If you override, you should generally always call this base class implementation.

Parameters

font	Pointer to the Font whose render size has changed.

Returns

true if some action was taken.
false if no action was taken (i.e font is not used here).

Reimplemented from CEGUI::WindowRenderer.

void CEGUI::FalagardEditbox::render ( )

virtual

Populate render cache.

This method must be implemented by all window renderers and should perform the rendering operations needed for this widget. Normally using the Falagard API...

Implements CEGUI::WindowRenderer.

void CEGUI::FalagardEditbox::setColourRectToOptionalPropertyColour	(	const String &	propertyName,
		ColourRect &	colour_rect
	)		const

Set the given ColourRect to the colour(s) fetched from the named property if it exists, else the default colour of black.

Parameters

propertyName	String object holding the name of the property to be accessed if it exists.
colour_rect	Reference to a ColourRect that will be set.

void CEGUI::FalagardEditbox::setTextFormatting ( const HorizontalTextFormatting format )

Sets the horizontal text formatting to be used from now onwards.

Parameters

format

Specifies the formatting to use. Currently can only be one of the following HorizontalTextFormatting values:

HTF_LEFT_ALIGNED (default)
HTF_RIGHT_ALIGNED
HTF_CENTRE_ALIGNED
