Detailed Description

The SvgTextCursor class.

This class handles cursor movement and text editing operations.

It acts as the KoToolSelection for SvgTextTool, allowing it to integrate with the basic KoToolBase functionality for copy, cut paste and clear.

A selection is defined as the anchor being different from the cursor position, with the move operation accepting whether you want to shift the cursor position.

It is also a shape listener to allow the textcursor to update itself whenever the corresponding text shape changes.

		const QSet< KoSvgTextProperties::PropertyId >	removeProperties = QSet<KoSvgTextProperties::PropertyId>(),
		bool	paragraphOnly = false,
		bool	selectWord = false )

mergePropertiesIntoSelection Within Krita's SVG/CSS text system, it is possible to apply incomplete properties to a whole range. In that case, only the existing properties are applied. Properties can also be removed this way.

Parameters

props	– properties to apply.
removeProperties	– properties to be removed.
paragraphOnly	– whether to apply to the paragraph.
selectWord	– whether to select the word if there's no selection.
