Detailed Description

An abstract base class which can be implemented by components that function as text editors.

This class allows different types of text editor component to provide a uniform interface, which can be used by things like OS-specific input methods, on-screen keyboards, etc.

Member Function Documentation

getCaretRectangle()

virtual Rectangle<int> TextInputTarget::getCaretRectangle ( )

pure virtual

Returns the position of the caret, relative to the component's origin.

Implemented in TextEditor, and CodeEditorComponent.

Referenced by CodeEditorComponent::getCaretPos().

getHighlightedRegion()

virtual Range<int> TextInputTarget::getHighlightedRegion ( ) const

pure virtual

Returns the extents of the selected text region, or an empty range if nothing is selected,.

Implemented in TextEditor, and CodeEditorComponent.

Referenced by CodeEditorComponent::getSelectionEnd().

getKeyboardType()

virtual VirtualKeyboardType TextInputTarget::getKeyboardType ( )

inlinevirtual

Returns the target's preference for the type of keyboard that would be most appropriate.

This may be ignored, depending on the capabilities of the OS.

Reimplemented in TextEditor.

getTextInRange()

virtual String TextInputTarget::getTextInRange ( const Range< int > &  range ) const

pure virtual

Returns a specified sub-section of the text.

Implemented in TextEditor, and CodeEditorComponent.

Referenced by CodeEditorComponent::getSelectionEnd().

insertTextAtCaret()

virtual void TextInputTarget::insertTextAtCaret ( const String &  textToInsert )

pure virtual

Inserts some text, overwriting the selected text region, if there is one.

Implemented in TextEditor, and CodeEditorComponent.

Referenced by CodeEditorComponent::getSelectionEnd().

isTextInputActive()

virtual bool TextInputTarget::isTextInputActive ( ) const

pure virtual

Returns true if this input target is currently accepting input.

For example, a text editor might return false if it's in read-only mode.

Implemented in TextEditor, and CodeEditorComponent.

setHighlightedRegion()

virtual void TextInputTarget::setHighlightedRegion ( const Range< int > &  newRange )

pure virtual

Sets the currently-selected text region.

Implemented in TextEditor, and CodeEditorComponent.

Referenced by CodeEditorComponent::getSelectionEnd().

setTemporaryUnderlining()

virtual void TextInputTarget::setTemporaryUnderlining ( const Array< Range< int > > &  underlinedRegions )

pure virtual

Sets a number of temporarily underlined sections.

This is needed by MS Windows input method UI.

Implemented in TextEditor, and CodeEditorComponent.
