Pagination Example with PageBreak
|
||||||
|
|
||||||
|
This example demonstrates:
|
||||||
|
- Using PageBreak to force content onto new pages
|
||||||
|
- Multi-page document layout with automatic page creation
|
||||||
|
- Different content types across multiple pages
|
||||||
|
- Page numbering and document flow
|
||||||
|
- Combining text, images, and tables across pages
|
||||||
|
|
||||||
|
This shows how to create multi-page documents with explicit page breaks.

Link Navigation Example

This example demonstrates:
|

- Creating clickable links with LinkedWord
|

|
- Different link types (INTERNAL, EXTERNAL, API, FUNCTION)
|
||||||
|
- Link styling with underlines and colors
|
||||||
|
- Link callbacks and event handling
|
||||||
|
- Interactive link states (hover, pressed)
|
||||||
|
- Organizing linked content in paragraphs
|
||||||
|
|
||||||
|
This shows how to create interactive documents with hyperlinks.

This example demonstrates:
|

|
- All FormFieldType variations (TEXT, PASSWORD, EMAIL, etc.)
|
||||||
|
- Form layout with multiple fields
|
||||||
|
- Field labels and validation
|

|
- Form submission callbacks
|
||||||
|
- Organizing forms on pages
|
||||||
|
|

This shows how to create interactive forms with all available field types.

## 🆕 New Examples (2024-11)
|
||||||
|
|
||||||
|
These examples address critical coverage gaps and demonstrate advanced features:
|
||||||
|
|
||||||
|
### 08. Pagination with PageBreak (NEW) ✅
|
||||||
|
**`08_pagination_demo.py`** - Multi-page documents with explicit and automatic pagination
|
||||||
|
|
||||||
|
```bash
|
||||||
|
python 08_pagination_demo.py
|
||||||
|
```
|
||||||
|
|
||||||
|
**Test Coverage:** [tests/examples/test_08_pagination_demo.py](../tests/examples/test_08_pagination_demo.py) - 11 tests
|
||||||
|
|
||||||
|
Demonstrates:
|
||||||
|
- Using `PageBreak` to force content onto new pages
|
||||||
|
- Multi-page document layout with explicit breaks
|
||||||
|
- Automatic pagination when content overflows
|
||||||
|
- Page numbering functionality
|
||||||
|
- Document flow control
|
||||||
|
- Combining pages into vertical strips
|
||||||
|
|
||||||
|
**Coverage Impact:** Fills critical gap - PageBreak layouter had NO examples before this!
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
### 09. Link Navigation (NEW) ✅
|
||||||
|
**`09_link_navigation_demo.py`** - All link types and interactive navigation
|
||||||
|
|
||||||
|
```bash
|
||||||
|
python 09_link_navigation_demo.py
|
||||||
|
```
|
||||||
|
|
||||||
|
**Test Coverage:** [tests/examples/test_09_link_navigation_demo.py](../tests/examples/test_09_link_navigation_demo.py) - 10 tests
|
||||||
|
|
||||||
|
Demonstrates:
|
||||||
|
- **Internal links** - Document navigation (`#section1`, `#section2`)
|
||||||
|
- **External links** - Web URLs (`https://example.com`)
|
||||||
|
- **API links** - API endpoints (`/api/settings`, `/api/save`)
|
||||||
|
- **Function links** - Direct function calls (`calculate()`, `process()`)
|
||||||
|
- Link styling (underlined, color-coded by type)
|
||||||
|
- Link callbacks and interactivity
|
||||||
|
- Mixed text and link paragraphs
|
||||||
|
|
||||||
|
**Coverage Impact:** Comprehensive - All 4 LinkType variations demonstrated!
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
### 10. Comprehensive Forms (NEW) ✅
|
||||||
|
**`10_forms_demo.py`** - All 14 form field types with validation
|
||||||
|
|
||||||
|
```bash
|
||||||
|
python 10_forms_demo.py
|
||||||
|
```
|
||||||
|
|
||||||
|
**Test Coverage:** [tests/examples/test_10_forms_demo.py](../tests/examples/test_10_forms_demo.py) - 9 tests
