## 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_COMMAND_TEXT_ENTER` and `wxEVT_COMMAND_TEXT_UPDATED`, 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.

Starts batching undo history for commands.

bool wxRichTextCtrl::BeginBold | ( |  | ) | `[inline]`

Begins using bold.

bool wxRichTextCtrl::BeginCharacterStyle | ( | const wxString & | characterStyle | ) | `[inline]`

Begins using the named character style.

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

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.

bool wxRichTextCtrl::BeginLineSpacing | ( | int | lineSpacing | ) | `[inline]`

Begins appling line spacing.

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.

| ) |  |  | `[inline]`

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.

| ) |  |  | `[virtual]`

Gets the attributes at the given position.

This function gets the uncombined style - that is, the attributes associated with the paragraph or character content, and not necessarily the combined attributes you see on the screen. To get the combined attributes, use GetStyle().

If you specify (any) paragraph attribute in style's flags, this function will fetch the paragraph attributes. Otherwise, it will return the character attributes.

wxPerl Note: In wxPerl this method is implemented as GetUncombinedStyle(position) returning a 2-element list (ok, attr).

Returns the cursor to be used over URLs.

wxRichTextLine* wxRichTextCtrl::GetVisibleLineForCaretPosition | ( | long | caretPosition | ) | const

Internal helper function returning the line for the visible caret position.

If the caret is shown at the very end of the line, it means the next character is actually on the following line. So this function gets the line we're expecting to find if this is the case.

virtual bool wxRichTextCtrl::HasCharacterAttributes | ( | const wxRichTextRange & | range,
|  | const wxRichTextAttr & | style |
| ) |  |  | const`[inline, virtual]`

If any of the attributes are different within the range, the test fails.

You can use this to implement, for example, bold button updating. style must have flags indicating which attributes are of interest.

virtual bool wxRichTextCtrl::HasParagraphAttributes | ( | const wxRichTextRange & | range,
|  | const wxRichTextAttr & | style |
| ) |  |  | const`[inline, virtual]`

Test if this whole range has paragraph attributes of the specified kind.

If any of the attributes are different within the range, the test fails. You can use this to implement, for example, centering button updating. style must have flags indicating which attributes are of interest.

virtual bool wxRichTextCtrl::HasSelection | ( |  | ) | const`[virtual]`

Returns true if there is a selection and the object containing the selection was the same as the current focus object.

virtual bool wxRichTextCtrl::HasUnfocusedSelection | ( |  | ) | const`[virtual]`

Returns true if there was a selection, whether or not the current focus object is the same as the selection's container object.

virtual wxTextCtrlHitTestResult wxRichTextCtrl::HitTest | ( | const wxPoint & | pt,
|  | long * | pos |
| ) |  |  | const`[virtual]`

Finds the character at the given position in pixels.

bool wxRichTextCtrl::IsDefaultStyleShowing | ( |  | ) | const`[inline]`

Returns true if the user has recently set the default style without moving the caret, and therefore the UI needs to reflect the default style and not the style at the caret.

Below is an example of code that uses this function to determine whether the UI should show that the current style is bold.

See also:
  SetAndShowDefaultStyle().

virtual bool wxRichTextCtrl::IsEditable | ( |  | ) | const`[virtual]`

Returns true if the control is editable.

- wxRICHTEXT_SETSTYLE_CHARACTERS_ONLY: specifies that the style should only be applied to characters, and not the paragraph. This allows content styling to be preserved independently from that of e.g. a named paragraph style.
- wxRICHTEXT_SETSTYLE_RESET: resets (clears) the existing style before applying the new style.
- wxRICHTEXT_SETSTYLE_REMOVE: removes the specified style. Only the style flags are used in this operation.
