| 45 |
|
|---|
| 46 | The Code Editor example shows how to create a simple editor that
|
|---|
| 47 | has line numbers and that highlights the current line.
|

|
|---|
| 49 | \image codeeditor-example.png
|
|---|
| 50 |
|
|---|
| 51 | As can be seen from the image, the editor displays the line
|
|---|
| 52 | numbers in an area to the left of the area for editing. The editor
|
|---|
| 53 | will highlight the line containing the cursor.
|
|---|
| 54 |
|
|---|
| 55 | We implement the editor in \c CodeEditor, which is a widget that
|
|---|
| 56 | inherits QPlainTextEdit. We keep a separate widget in \c
|
|---|
| 57 | CodeEditor (\c LineNumberArea) onto which we draw the line
|
|---|
| 58 | numbers.
|
|---|
| 59 |
|
|---|
| 60 | QPlainTextEdit inherits from QAbstractScrollArea, and editing
