virtual const wxRichTextAttr& wxRichTextParagraphLayoutBox::GetBasicStyle | ( |  | ) | const

Returns 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).

Reimplemented from wxRichTextCompositeObject.

Reimplemented in wxRichTextTable, and wxRichTextField.

| inline

Returns the associated control.

virtual bool wxRichTextParagraphLayoutBox::GetStyle | ( | long | position,
|  | wxRichTextAttr & | style
| ) |  |
| virtual

Returns the combined text attributes for this 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.

wxRichTextAttr wxRichTextParagraphLayoutBox::GetStyleForNewParagraph | ( | wxRichTextBuffer * | buffer,
|  | long | pos,
|  | bool | caretPosition = `false`,
|  | bool | lookUpNewParaStyle = `false`

Returns the style that is appropriate for a new paragraph at this position.

If the previous paragraph has a paragraph style name, looks up the next-paragraph style.

virtual bool wxRichTextParagraphLayoutBox::GetStyleForRange | ( | const wxRichTextRange & | range,
|  | wxRichTextAttr & | style
| ) |  |
| virtual

This function gets a style representing the common, combined attributes in the given range.

Attributes which have different values within the specified range will not be included the style flags.

The function is used to get the attributes to display in the formatting dialog: the user can edit the attributes common to the selection, and optionally specify the values of further attributes to be applied uniformly.

To apply the edited attributes, you can use SetStyle() specifying the wxRICHTEXT_SETSTYLE_OPTIMIZE flag, which will only apply attributes that are different from the combined attributes within the range. So, the user edits the effective, displayed attributes for the range, but his choice won't be applied unnecessarily to content. As an example, say the style for a paragraph specifies bold, but the paragraph text doesn't specify a weight. The combined style is bold, and this is what the user will see on-screen and in the formatting dialog. The user now specifies red text, in addition to bold. When applying with SetStyle(), the content font weight attributes won't be changed to bold because this is already specified by the paragraph. However the text colour attributes will be changed to show red.

virtual wxRichTextStyleSheet* wxRichTextParagraphLayoutBox::GetStyleSheet | ( |  | ) | const
| virtual

Returns the style sheet associated with the overall buffer.

Reimplemented in wxRichTextBuffer.

virtual wxString wxRichTextParagraphLayoutBox::GetText | ( |  | ) | const

virtual bool wxRichTextParagraphLayoutBox::GetUncombinedStyle | ( | long | position,
|  | wxRichTextAttr & | style
| ) |  |
| virtual

Returns the content (uncombined) attributes for this position.

virtual long wxRichTextParagraphLayoutBox::GetVisibleLineNumber | ( | long | pos,
|  | bool | caretPosition = `false`,
|  | bool | startOfLine = `false`
| ) |  | const
| virtual

Given a position, returns the number of the visible line (potentially many to a paragraph), starting from zero at the start of the buffer.

We also have to pass a bool (startOfLine) that indicates whether the caret is being shown at the end of the previous line or at the start of the next, since the caret can be shown at two visible positions for the same underlying position.

virtual wxString wxRichTextParagraphLayoutBox::GetXMLNodeName | ( |  | ) | const
| inline virtual

Returns the XML node name of this object.

This must be overridden for wxXmlNode-base XML export to work.

Reimplemented from wxRichTextObject.

Reimplemented in wxRichTextTable, wxRichTextCell, wxRichTextField, and wxRichTextBox.

virtual bool wxRichTextParagraphLayoutBox::HasCharacterAttributes | ( | const wxRichTextRange & | range,
|  | const wxRichTextAttr & | style
| ) |  | const
| virtual

Test if this whole range has character 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, bold button updating. style must have flags indicating which attributes are of interest.

virtual bool wxRichTextParagraphLayoutBox::HasParagraphAttributes | ( | const wxRichTextRange & | range,
|  | const wxRichTextAttr & | style
| ) |  | const
| 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 int wxRichTextParagraphLayoutBox::HitTest | ( | wxDC & | dc,
|  | wxRichTextDrawingContext & | context,
|  | const wxPoint & | pt,
|  | long & | textPosition,
|  | wxRichTextObject ** | obj,
|  | wxRichTextObject ** | contextObj,
|  | int | flags = `0`
| ) |  |
| virtual

Hit-testing: returns a flag indicating hit test details, plus information about position.

contextObj is returned to specify what object position is relevant to, since otherwise there's an ambiguity. @ obj might not be a child of contextObj, since we may be referring to the container itself if we have no hit on a child - for example if we click outside an object.

The function puts the position in textPosition if one is found. pt is in logical units (a zero y position is at the beginning of the buffer).

Returns
  One of the wxRichTextHitTestFlags values.

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

|  | int | flags = `wxRICHTEXT_SETPROPERTIES_WITH_UNDO`
| ) |  |
| virtual

Sets the properties for the given range, passing flags to determine how the attributes are set.

You can merge properties or replace them.

The end point of range is specified as the last character position of the span of text, plus one. So, for example, to set the properties for a character at position 5, use the range (5,6).

flags may contain a bit list of the following values:

- wxRICHTEXT_SETPROPERTIES_NONE: no flag.
- wxRICHTEXT_SETPROPERTIES_WITH_UNDO: specifies that this operation should be undoable.
- wxRICHTEXT_SETPROPERTIES_PARAGRAPHS_ONLY: specifies that the properties should only be applied to paragraphs, and not the content.
- wxRICHTEXT_SETPROPERTIES_CHARACTERS_ONLY: specifies that the properties should only be applied to characters, and not the paragraph.

Associates a control with the buffer, for operations that for example require refreshing the window.

virtual bool wxRichTextParagraphLayoutBox::SetStyle | ( | const wxRichTextRange & | range,
|  | const wxRichTextAttr & | style,
|  | int | flags = `wxRICHTEXT_SETSTYLE_WITH_UNDO`
| ) |  |
| virtual

Sets the attributes for the given range.

Pass flags to determine how the attributes are set.

The end point of range is specified as the last character position of the span of text. So, for example, to set the style for a character at position 5, use the range (5,5). This differs from the wxRichTextCtrl API, where you would specify (5,6).

flags may contain a bit list of the following values:

- wxRICHTEXT_SETSTYLE_NONE: no style flag.
- wxRICHTEXT_SETSTYLE_WITH_UNDO: specifies that this operation should be undoable.
- wxRICHTEXT_SETSTYLE_OPTIMIZE: specifies that the style should not be applied if the combined style at this point is already the style in question.
- wxRICHTEXT_SETSTYLE_PARAGRAPHS_ONLY: specifies that the style should only be applied to paragraphs, and not the content. This allows content styling to be preserved independently from that of e.g. a named paragraph style.
- 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.

virtual void wxRichTextParagraphLayoutBox::SetStyle | ( | wxRichTextObject * | obj,
