## Detailed Description

wxRichTextCtrl provides a generic, ground-up implementation of a text control capable of showing multiple styles and images.

wxRichTextCtrl sends notification events: see wxRichTextEvent.

It also sends the standard wxTextCtrl events `wxEVT_TEXT_ENTER` and `wxEVT_TEXT`, and wxTextUrlEvent when URL content is clicked.

For more information, see the wxRichTextCtrl Overview.

## Styles

This class supports the following styles:

- wxRE_CENTRE_CARET:
  The control will try to keep the caret line centred vertically while editing. wxRE_CENTER_CARET is a synonym for this style.
- wxRE_MULTILINE:
  The control will be multiline (mandatory).
- wxRE_READONLY:
  The control will not be editable.

## ◆ ApplyStyle()

virtual bool wxRichTextCtrl::ApplyStyle | ( | wxRichTextStyleDefinition * | def | ) |
| virtual

Applies the style sheet to the buffer, matching paragraph styles in the sheet against named styles in the buffer.

This might be useful if the styles have changed. If sheet is nullptr, the sheet set with SetStyleSheet() is used. Currently this applies paragraph styles only.

| virtual

Starts batching undo history for commands.

## ◆ BeginBold()

bool wxRichTextCtrl::BeginBold | ( |  | ) |

## ◆ BeginLeftIndent()

bool wxRichTextCtrl::BeginLeftIndent | ( | int | leftIndent,
|  | int | leftSubIndent = `0`
| ) |  |

Begins applying a left indent and subindent in tenths of a millimetre.

The subindent is an offset from the left edge of the paragraph, and is used for all but the first line in a paragraph. A positive value will cause the first line to appear to the left of the subsequent lines, and a negative value will cause the first line to be indented to the right of the subsequent lines.

wxRichTextBuffer uses indentation to render a bulleted item. The content of the paragraph, including the first line, starts at the leftIndent plus the leftSubIndent.

Parameters

  leftIndent | The distance between the margin and the bullet.
  leftSubIndent | The distance between the left edge of the bullet and the left edge of the actual paragraph.

## ◆ BeginLineSpacing()

bool wxRichTextCtrl::BeginLineSpacing | ( | int | lineSpacing | ) |

spacing is a multiple, where 10 means single-spacing, 15 means 1.5 spacing, and 20 means double spacing.

The wxTextAttrLineSpacing constants are defined for convenience.

## ◆ BeginListStyle()

|  | int | level = `1`,
|  | int | number = `1`
| ) |  |

Optionally, you can also pass a level and a number.

## ◆ BeginNumberedBullet()

bool wxRichTextCtrl::BeginNumberedBullet | ( | int | bulletNumber,
|  | int | leftIndent,
|  | int | leftSubIndent,
|  | int | bulletStyle = `wxTEXT_ATTR_BULLET_STYLE_ARABIC|wxTEXT_ATTR_BULLET_STYLE_PERIOD`
| ) |  |

Begins a numbered bullet.

This call will be needed for each item in the list, and the application should take care of incrementing the numbering.

bulletNumber is a number, usually starting with 1. leftIndent and leftSubIndent are values in tenths of a millimetre. bulletStyle is a bitlist of the wxTextAttrBulletStyle values.

wxRichTextBuffer uses indentation to render a bulleted item. The left indent is the distance between the margin and the bullet. The content of the paragraph, including the first line, starts at leftMargin + leftSubIndent. So the distance between the left edge of the bullet and the left of the actual paragraph is leftSubIndent.

## ◆ BeginParagraphSpacing()

|  | int | after
| ) |  |

|  | int | leftSubIndent,
|  | int | bulletStyle = `wxTEXT_ATTR_BULLET_STYLE_SYMBOL`
| ) |  |

Begins applying a symbol bullet, using a character from the current font.

See BeginNumberedBullet() for an explanation of how indentation is used to render the bulleted paragraph.

virtual void wxRichTextCtrl::SelectAll | ( |  | ) |
| virtual

Selects all the text in the buffer.

## ◆ SelectNone()

virtual void wxRichTextCtrl::SelectNone | ( |  | ) |
| virtual

Cancels any selection.

See also
  IsDefaultStyleShowing().

## ◆ SetBasicStyle()

virtual void wxRichTextCtrl::SetBasicStyle | ( | const wxRichTextAttr & | style | ) |

Sets the basic (overall) style.

This is the style of the whole buffer before further styles are applied, unlike the default style, which only affects the style currently being applied (for example, setting the default style to bold will cause subsequently inserted text to be bold).

## ◆ SetCaretAtLineStart()

void wxRichTextCtrl::SetCaretAtLineStart | ( | bool | atStart | ) |

| ) |  |

Sets the caret position.

The caret position is the character position just before the caret. A value of -1 means the caret is at the start of the buffer. Please note that this does not update the current editing style from the new position or cause the actual caret to be refreshed; to do that, call wxRichTextCtrl::SetInsertionPoint instead.

## ◆ SetCaretPositionAfterClick()

bool wxRichTextCtrl::SetCaretPositionAfterClick | ( | wxRichTextParagraphLayoutBox * | container,
