Interface IViewModule4
interface IViewModule4
Extends IViewModule3
This interface extends IViewModule3 with additional capability to create empty text view
without requiring a ITextLayout parameter.
Methods
makeEmptyTextView()
Creates a new empty ITextView object. This creates anITextView*makeEmptyTextView()
ITextView instance without requiring an ITextLayout parameter
at construction time. The text layout can be set later using ITextView::updateTextLayout
method when the content becomes available.
Use Cases:
- Lazy loading scenarios where text content is fetched asynchronously
- Performance optimization when creating multiple views upfront but populating content later
- Dynamic UI construction where layout parameters depend on runtime conditions
- The returned ITextView is in an uninitialized state until updateTextLayout() is called
- The view will not render any text content until a layout is provided
- The view can be added to the view hierarchy immediately, but will appear empty
- Calling updateTextLayout() triggers layout calculation and rendering
IViewModule::makeTextView when the ITextLayout is immediately available.
Use makeEmptyTextView() when you need to create the view first and populate content later.
Returns
ITextView*
A pointer to the newly created ITextView instance with empty text.
