wxTextAttrEx

Задать вопрос на форуме...

wxTextAttrEx is an extended version of wxTextAttr with more paragraph attributes. Currently it is only used with wxRichTextCtrl.

It is intended that eventually, the members of wxTextAttrEx will be folded into wxTextAttr, and wxTextAttr will be the official cross-platform API for text controls that support attributes. However, for now, wxTextAttrEx is provided as a means of enabling extra functionality in wxRichTextCtrl, while retaining some compatibility with the wxTextAttr API.

The most efficient method of accessing wxRichTextCtrl functionality is a third attribute class, wxRichTextAttr, which optimizes its storage to allow it to be used for implementing objects in a buffer, as well as access to that buffer.

This section only documents the additional members; see wxTextAttr for the remaining functions.

Constants

The following values can be passed to SetAlignment to determine paragraph alignment.

enum wxTextAttrAlignment
{
    wxTEXT_ALIGNMENT_DEFAULT,
    wxTEXT_ALIGNMENT_LEFT,
    wxTEXT_ALIGNMENT_CENTRE,
    wxTEXT_ALIGNMENT_CENTER = wxTEXT_ALIGNMENT_CENTRE,
    wxTEXT_ALIGNMENT_RIGHT,
    wxTEXT_ALIGNMENT_JUSTIFIED
};

These values are passed in a bitlist to SetFlags to determine what attributes will be considered when setting the attributes for a text control.
